1. Description 

This manual describes the IU30 Impregnation Unit, together with full details on the initial 

setting‐up, operation and maintenance of the machine. When using this manual it is useful 

to refer to the appropriate diagrams, in particular to the main diagram (Figure 1 on previous 

page). The bracketed numbers which appear in the following text refer to the parts of the 

machine highlighted on the diagram. 

1.1 Equipment Use 

The Vacuum Impregnation system is intended for the out gassing of porous geological rock 

materials such as sandstone, soils, gypsum, chalk etc... in order to impregnate and 

consolidate the materials with epoxy resin (Epoxy pack 301). 

This product is meant for use with Epoxy pack 301`and is not intended for the out gassing of 

other resins, polymers or other unknown volatiles which may be hazardous. 

It is not intended to be used for other applications out with the above stated purposes 

without the operator first obtaining agreement from the manufacturer. Any unauthorised 

process or improper use of the system may invalidate the warranty and could damage the 

machine and/or cause injury to the operator. Logitech do not accept liability for any 

improper use of the system resulting in damage or harmful results. 

1.2 Machine Designation 

The serial plate of the machine is located next to the mains inlet cable on the right side of 

the unit. The serial number is a 6 digit number in the format 00‐00‐00. The machine model 

is recognised by the first two numbers which will be: 73. The second two numbers denote 

the number of machines built that year and the final two numbers represent the year of 

manufacture. For example: 73‐05‐08 represents the 5th machine manufactured in 2008. 

1.3 Manufacturer Information 

These machines are manufactured by: 

Logitech Ltd 

Erskine Ferry Rd, 

Old Kilpatrick 

Glasgow 

G60 5EU, 

Scotland, UK 


2. Installation 

2.1 Unpacking Instructions 

The machine is packed in a wooden transit case and supported internally using expandable 

foam to provide maximum protection during transit. 

For unpacking, remove the top from the wooden case. Then remove all internal packing 

foam/materials and dismantle the wooden case by removing all four sides. 

NOTE ‐ This machine is very heavy due to the integral vacuum pump, it weighs 74kg. No 

attempt should be made to lift the IU30 without assistance. We recommend that a 

minimum of 2 people are required for safe lifting. 

Lift the machine by the base casting and place on a suitable level surface, allowing enough 

clearance distance for power cables and a minimum of 2" (5.08cm) clearance for air 

circulation behind the machine. 

At this point a hose connection should be made to the vacuum pump vent at the rear of the 

machine to a suitable ventilation point. 

2.2 Initial Check & Oil Fill 

When setting up the IU30 for the first time, the following procedure should be followed to 

ensure that the machine is in proper working order. 

NOTE ‐ UNSCREW THE OIL FILLER CAP (6) AND ADD OIL FROM THE CONTAINER SUPPLIED 

TO FILL THE VACUUM PUMP TO THE MAXIMUM MARK ON THE SIGHT GLASS (5). 

Replace the filler cap (6) (the remaining vacuum oil should be stored for topping up at a 

future date). 

Inspect the machine visually to ensure that it has not been damaged during transit. Contact 

Logitech and/or the carrier immediately if damage has occurred. 

The plug wiring is as follows: line ‐ brown; neutral ‐ blue; earth ‐ yellow/green. 

Plug the power cable into the connection point at the right hand side of the machine. 

Connect the machine to a suitable electrical supply, having ensured that the voltage rating 

corresponds to your local mains supply. 


2.3 Checking the Vacuum 

Fit the resin feed system to the resin and sample chambers, as shown in the diagram for 

section 3.1.3, ensuring that the O‐rings, shown in section 3.1.1, are in place contacting the 

top of the glass lid (16). Check visually that the O‐rings on the sample chamber (1) are in 

place and that the resin chamber (2) is sitting squarely under the glass lid (16) on its spring 

loaded base. Ensure that the resin and sample chamber valves (10, 12) and the resin and 

sample chamber vents (11, 13) are closed. 

Switch on the machine using the mains switch at the side by the electrical inlet. The pump 

will start and the mains indicator light (8) on the pirani gauge (9) will glow green. The pirani 

gauge (9) will progressively reduce in reading to the ultimate vacuum achieved by the pump 

over a period of up to half a minute. This should be in the region 10 ‐2 to 5x10 ‐2 mbar. 

Slowly open the sample chamber valve (12) ‐ the sample chamber (1) will start to pump 

down. On a new machine the vacuum will gradually build over a period which may be as 

long as half an hour, depending on water vapour etc., which has accumulated in transit 

(after this first pump down the sample chamber should evacuate in under five minutes). If 

the vacuum fails to start building, ensure that all O‐rings are sitting on clean surfaces. 

Repeat this check after opening the resin chamber valve (10), so that both chambers are 

evacuated. In both cases the ultimate vacuum reach will depend on atmospheric and other 

conditions but should be in the region of 5x10 ‐2 mbar to 10 ‐1 mbar. 

2.4 Health & Safety 

When operating this unit the operator must be aware of the risks involved when working 

with resins and vacuum pressure. 

a) The unit is operated under sufficient vacuum pressure to accelerate the exothermic 

reaction in the resin when out gassing. Care must be taken to slowly control the rate 

of expansion of the resin bubbling up or effervescing to retain it inside the mixing 

vessel. This is done by manually adjusting rate of air removal via the vacuum/air 

control valves. 

b) The vacuum pump exhaust port emits oil vapour and must be vented correctly 

through a suitable oil mist filter (see separate vacuum pump manual if supplied with 

the machine) or to the facility exhaust system to prevent oil mist in the working 

area. 

c) The system is not sensitive to vibration and can be installed on a standard bench 

which will support the weight (74kg). 


d) The system should be situated away from areas of dust or particle contamination as 

this may affect the quality of the impregnation if airborne particulates become 

trapped in the resin layer. 

e) No special lighting is required for the system and the machine may be operated 

from 200 lux or above environment with no flicker or glare. 

2.5 Machine Noise Levels 

The IU30 series of machines in normal operation run at a noise level below 70dB (A). 

The main noise from the unit occurs through the oil pump and motor which is below 70dB 

(A). 

The IU30 unit was tested using a calibrated ISOTECH SLM‐52N (serial number 090514361) 

sound level gauge (technical data included in the technical file) over a one hour period and 

averaged below 70dB (A). Background levels were recorded at 58dB (A) +/‐2dB before and 

after the tests. The sound meter was placed 1m from the unit and facing the unit directly at 

a height 1.6m from the floor. 


3. Operation 

3.1 Set Up 

Before assembling the resin (2) and sample (1) chambers, ensure that all rubber O‐rings and 

equipment contact surfaces are clean and dirt free by wiping thoroughly with isopropanol 

alcohol. A small quantity of vacuum grease may also be used on contact surfaces to reduce 

the likelihood of resin contamination. 

3.1.1 The Resin Chamber 

Figure 2: The Resin Chamber 

The resin chamber (2) consists of a metal cylinder with two 14 x 0.35cm rubber O‐rings fitted 

to upper and lower grooves with a metal base plate. This plate carries a vacuum inlet tube 

with a single O‐ring. The resin chamber base plate should be fitted neatly onto the six 

springs on the base at the left hand side of the IU30 with the vacuum inlet tube entered into 

the hole in the base. It is rarely necessary to remove this after initial fitting. 

Place a suitable receptacle, such as a 500ml beaker, for the resin inside the resin chamber. 

This should not obstruct the vacuum inlet on the base plate. 

3.1.2 The Sample Chamber 

This chamber has upper and lower grooves, into which are fitted two 24 x 0.5cm rubber O‐ 

rings. The chamber can then be placed directly on to the right hand side of the IU30 base. 

Ensure that the lower end of the chamber fits around the vacuum inlet and is sitting cleanly, 

with its O‐ring on the base, located by three screw heads. 

The disposable sample chamber lining should be placed inside the sample chamber (1). This 

will protect the chamber from resin spills and aid faster cleaning of machine parts. 

Samples to be impregnated should be as clean and dry as possible. They should be placed in 

suitable containers, usually made from heavy gauge aluminium foil, ensuring that they are 


tall enough for the resin to completely cover the samples when impregnated. Place sample 

containers or moulds inside the lining bucket. 

Take care to place the samples in an appropriate position underneath the resin feed 

system’s (14) outlet (22) to the sample chamber. If multiple samples are to be impregnated, 

the resin feed inlet (15) can be angled to access the samples. The vacuum inlet on the floor 

of the sample chamber (1) should NOT be covered at any time (a spacer is fitted to the 

machine base to prevent the plastic liner from obstructing the inlet). 

3.1.3 Resin Feed System 

Figure 3: The Resin Feed System 

The resin feed system (item 14 on figure 1: Overview Diagram) should be set up in 

accordance with the above diagram, although there is no specific requirement for two 0.6 x 

0.2cm O‐rings (20) to be used at each side of the disposable resin feed tube. 

A length of quarter inch or 6mm plastic tube, approximately 1 metre in length, is used to 

transfer the resin from the resin chamber (2) where it is out‐gassed, to the sample chamber 

(1). 

To fit the plastic tubing use the following steps: 

17. Clamp bar 

18. Resin feed clamp 

19. 5x0.35cm O ring 

20. 0.6x0.2cm O ring 

21. Clamp nut 

22. To resin chamber 

23. Resin inlet nut 

24. To sample chamber 

25. Resin inlet 

a) Thread the clamp (18), followed by the small O‐ring (20), onto 

the tube. 

b) The clamp bar (17) should now be screwed up tight, closing the 

tubing but leaving sufficient tube to reach the bottom of the 

resin beaker. 

c) Screw the clamp nut (21) tightly onto the underside of the 

clamp (the O‐rings will be secured in place and the tube sealed 

to the clamp). 

d) Fit the larger rubber O‐rings (19) to the underside of the clamp 

unit. 


e) Slide the resin inlet nut (23), small O‐ring (20), and resin inlet 

onto the opposite end of the plastic tubing and screw them 

together tightly. 

f) Add the second larger O‐ring (19) to the underside groove of the 

resin inlet. 

g) Lower the glass chamber top plate (16), leaving it resting on the 

resin and sample chambers’ top O‐rings. 

h) Fit the resin inlet (15) and resin feed clamp (18) with the tube 

into the holes in the glass lid. 

3.2. Sequence Operation 

3.2.1. Evacuating the Sample and Resin Chambers 

a) Add samples to the sample chamber (1) and a resin beaker to 

the resin chamber (2). 

b) Switch the vacuum pump on. 

c) Close both the resin chamber vent (11) and the sample chamber 

vent (13). 

d) Open the sample chamber valve (12). 

e) It may be necessary to press down on the glass plate, in order 

for the sample chamber to seal itself. 

f) The pirani gauge (9) will indicate whether the sample chamber 

(1) is evacuating. 

g) Ensure that the resin chamber (2) is sealed firmly under the 

reinforced glass plate lid (16). 

h) Open the resin chamber valve (10). 

i) The pirani gauge (9) should now register that the resin chamber 

(2) is being evacuated. 

NOTE ‐ Should the pirani gauge (9) indicate that the sample chamber (1) is not evacuating, 

check that the resin feed clamp (18) is tightened sufficiently ‐ any seepage from the clamp 

area will prevent a vacuum from forming in the sample chamber (1). 

Once satisfied that both the resin (2) and sample chambers (1) are operating correctly, the 

samples should be left to outgas in the sample chamber (NB ‐ open the sample chamber 

valve (12)). Evacuate the samples to a level dependent on material and results required 

(soils are best left to outgas overnight). Samples are outgassed to a minimum of 1x10 ‐1 Mbar 

to achieve the best results from the system. 

NOTE ‐ The higher the vacuum achieved and the longer the sample is outgassed, the better 

the results that can be obtained. 


3.2.2. Evacuating the Resin 

a) When the sample has been out gassed for a sufficient period of 

time, mix the resin. 

Mix ratios of the Logitech Epoxy 301 (Ocon‐185) 

Mixing by volume: 3 parts of Resin (part A) to 1 part of Hardener (part B) 

Mixing by weight: 4 parts of Resin (part A) to 1 part of Hardener (part B) 

Mix ratio of Logitech Keystone oil Blue dye (Ocon‐241) 

1 gram of Keystone oil blue dye – 100ml of the mixed Epoxy 301 

b) Close the resin chamber valve (10). 

c) Open the resin chamber vent (11) and lift off the resin feed 

clamp (18). 

d) Place the funnel in the resin chamber hole and pour the resin 

into the beaker below. 

e) Replace the resin feed clamp (18) and switch off the resin 

chamber vent (11). 

f) Open the resin chamber valve (10) very slowly, watching the 

resin level closely. 

g) At this point the vacuum throughout the system will drop and 

then slowly rise as the resin is evacuated. 

The resin will begin to froth and must be controlled to ensure that it does not rise 

sufficiently to spill from the beaker and enter the vacuum system. This would cause serious 

damage to the vacuum pump system. If spillage outside the resin beaker occurs, it is 

essential to abort the run and clean up the spillage immediately. 

Control the resin level by manipulating the resin chamber valve (10) (opening and closing the 

valve as required). The resin quickly settles, giving out larger intermittent bubbles, and at 

this point the resin chamber valve (10) can be fully opened. 

During this sequence, it is necessary to open the gas ballast control (7) to purge the vacuum 

pump. This is achieved by turning the control (7) 45 degrees in an anti‐clockwise direction 

(where severe purging is required, the control (7) may be turned 90 degrees in an anti‐ 

clockwise direction). 

NOTE ‐ Resins with highly volatile components may not be suitable for use with this 

equipment. 

The vacuum will gradually rise as the resin out‐gassing becomes noticeably less and less. The 

final vacuum will normally be approximately 2 x 10 ‐1 Mbar, depending upon the resin used. 

An average time for the resin out‐gassing process is approximately 15 minutes. 

3.2.3. Adding the Resin to the Sample 

a) Close the resin chamber valve (10). 

b) Open the resin chamber vent (11). 

c) Slowly loosen the resin feed clamp (18), until the resin starts to 

pull through to the sample chamber (1). 


d) Allow enough resin to flow into the sample to adequately cover 

it before closing the resin feed clamp (18) tightly. 

Leave the submerged samples in the evacuated sample chamber (1) for as long as the 

properties of the resin used will safely allow. If using Logitech Epoxypack 301, this stage 

should take 15 minutes. The vacuum will continue to rise and further outgassing in the 

sample container will occur. 

When the desired vacuum is achieved, or when time expires due to resin pot life, switch off 

the sample chamber valve (12) and open the sample chamber vent (13). 

This causes air to be admitted to the system, impregnating the samples with resin by 

atmospheric pressure. Switch off the vacuum gauge and the vacuum pump. 

3.2.4. Completing the Process 

The resin feed system (14) can then be removed, the reinforced glass plate (16) raised and 

the samples removed from the sample chamber (1). These will cure overnight at room 

temperature. 

The resin feed system should then be dismantled. Once the disposable tube is unscrewed 

from the clamp (18) and inlet (25) parts. The tube can now be discarded. 

NOTE ‐ It is vital to remove all traces of resin and thoroughly clean all parts of the system 

before any resin cures. 

Both the resin (2) and sample (1) chambers should be dismantled. Remove the O‐rings 

and wipe them clean with isopropanol (in a well ventilated area), as this will effectively 

remove any resin before it hardens. 

Applying a small amount of silicon vacuum grease to the assembly will ease future cleaning 

operations. Good cleaning techniques, at the end of each impregnation, enable a good 

vacuum to be formed in subsequent operations and also ensures that dirt does not 

contaminate the vacuum system. 


4. Maintenance 

4.1 General 

Little maintenance of the equipment should be required other than regular and thorough 

cleaning of the machine and testing the vacuum system for leakage. 

Access to hidden components is gained by removal of the rear panel and should only be 

attempted after disconnection of the mains supply. 

Further work should only be carried out after discussion with Logitech Ltd., as removing 

the rear casing involves disturbing oil and electrical connections. 

4.2 Vacuum Pump – Potential Failures or Breakdowns 

(a) The most common interruption to normal operation is when the vacuum pump oil is 

contaminated and needs out gassed. See the vacuum pump manual for various 

settings. 

(b) Periodically check the oil level in the oil sight glass (5) and, if required, replenish with 

light vacuum pump oil as specified in the manufacturer's manual. The oil is applied 

by opening the oil filler cap (6) located on the top panel of the machine and topping 

up as necessary. 

(c) During the resin evacuation process, it is possible that contaminated vapours will 

gradually enter the pump. Whilst the pump is very tolerant of contamination, it is 

necessary to open the gas ballast control (7) (located on the top panel ) during this 

particular operation, thus introducing clean air into the system to purge the pump. 

(See pump manufacturer's manual for further information.) 

(d) Oil mist and fumes are channelled to the exhaust outlet at the rear of the machine. 

This may be connected to an extraction system or fitted with an Balston filter which 

can be supplied on request (Cat. No. 2VAC‐002). 

If the system failure cannot be found in the first instance contact either your local 

representative or the manufacturer for assistance. 

4.3 Vacuum System 

Periodically check the vacuum system connections, seals and "O" rings for wear and leakage, 

greasing as required. When necessary, repeat the vacuum check described in Section 2.3.

1.2 ATEX directive implications 

� This equipment is designed to meet the requirements of Group II Category 3 equipment in accordance with 

Directive 94/9/EC of the European Parliament and the Council of 23rd March 1994 on the approximation of 

the laws of the Member States concerning equipment and protective systems intended for use in potentially 

explosive atmospheres. (The ATEX Directive). 

The ATEX Category 3 applies in respect of potential ignition sources internal to the equipment. An ATEX Category 

has not been assigned in respect of potential ignition sources on the outside of the equipment as the equipment 

has not been designed for use where there is an external potentially explosive atmosphere. 

There is no potential source of ignition within the pump during normal operation but there may be potential 

sources of ignition under conditions of predicted and rare malfunction as defined in the Directive. Accordingly, 

although the pump is designed to pump flammable materials and mixtures, operating procedures should ensure 

that under all normal and reasonably predicted conditions, these materials and mixtures are not within 

explosive limits. Category 3 is considered appropriate for the avoidance of ignition in the case of a rare 

malfunction which allows flammable materials or mixtures to pass through the pump while within their explosive 

limits. 

� When flammable or pyrophoric materials are present within the equipment you must: 

� Not allow air to enter the equipment. 

� Ensure that the system is leak tight. 

� For further information, please contact Edwards: refer to the Addresses page at the end of this manual for 

details of your nearest Edwards company.

Introduction

Introduction 

A652–01–880 Issue S 

1.3 Description 

The Edwards RV rotary vane pump is shown in Figure 1. Refer to Figure 1 for item numbers in brackets in the following 

descriptions. The RV pumps are two-stage, oil-sealed, sliding-vane vacuum pumps. The pump has NW25 inlet (4) and 

outlet (7) ports, a gas-ballast control (5) and a mode selector (11). When the pump is switched off, an inlet-valve 

seals the inlet and prevents the suck-back of air and oil into the vacuum system. 

The RV3 and RV5 pumps have a retractable lifting handle (3). The RV8 and the RV12 pumps are fitted with a lifting 

bracket for use with suitable lifting equipment. 

An oil-pump delivers pressurised oil to the vacuum pumping mechanism in the RV pump. You can inspect the level 

and condition of the oil in the oil-box through a sight-glass (8). Two oil filler-plugs (6) and an oil drain-plug (9) are 

provided on the oil-box. 

The pump mechanism is driven directly by a single-phase or three-phase electric motor through a flexible 

motor-coupling. The motor is totally enclosed and is cooled by the motor cooling-fan which directs air along the 

motor fins. The pumps are cooled by an additional fan attached to the motor-coupling. 

Single-phase motors are fitted with an on/off switch (12) and a thermal overload device. When the motor is too hot, 

the thermal overload device switches off the pump. The thermal overload device has an automatic reset; when the 

motor cools down, the device resets and (unless you have incorporated suitable control equipment which must be 

manually reset: see Sections 3.7.2 and 3.8.2), the motor will restart. 

The pump is mounted on a base plate on rubber feet (10). Details of suitable vibration isolators and other accessories 

are provided in Section 7.4. 

Refer to Section 8 for additional information if your pump is PFPE-prepared. 

1.4 Performance modes and controls 

The pump has two controls: the mode selector (11) and the gas-ballast control (5). Six possible combinations of these 

controls allow for a wide choice of operating characteristics so you can optimise the performance of the pump for a 

given application. 

1.4.1 Mode selector 

The mode selector has two positions; refer to Section 4.2 to select these positions. Throughout the rest of this 

manual, the following convention is used: 

� The High Vacuum mode is specified by the � symbol. 

� The High Throughput mode is specified by the � symbol. 

With the mode selector set to High Vacuum mode �, pressurised oil is fed to the low vacuum stage only. In this mode 

of operation, the pump provides the best possible ultimate vacuum. 

With the mode selector set to High Throughput mode �, pressurised oil is fed to the high vacuum and low vacuum 

stages. In this mode of operation, the pump can sustain long-term high inlet pressures. 



1.4.2 Gas-ballast control 

A652–01–880 Issue S 

To pump high vapour loads, gas-ballast is delivered into the pump to prevent condensation of the vapour carried by 

the pumped gases. 

Air can be introduced to the low vacuum stage through the gas-ballast valve. Alternatively, an inert gas such as 

nitrogen can be supplied through a suitable external valve. 

The gas-ballast control has three positions: 

� Closed (position ‘0’) 

� Low flow (position ‘I’) 

� High flow (position ‘II’). 

1.5 Construction 

The pump-shafts and rotors are made of high-grade cast-iron. The pump-body and oil-box are made from 

cast-aluminium. All surfaces of the pump which are exposed to the pumped gases are free from copper, zinc and 

cadmium. 

Other materials of construction include fluorocarbon elastomer, nitrile, silicon, chemically-resistant polymers, nickel 

and stainless steel.

2.6 Electrical data: single-phase pumps 

Note: We recommend that you use fuses of the maximum ratings specified in Tables 9 and 10. You must not use 

fuses of a higher rating. 

The dual-voltage, dual-frequency motor is designed for a single-phase electrical supply and is suitable for 50 Hz or 

60 Hz operation. The motor can be manually switched between nominal supply voltages of 110–120 V and 220–240 V 

(refer to Section 3.7.1). 

When you start a cold pump, the motor will draw the start-up current shown in Tables 9 and 10 for up to several 

seconds, so you must use a slow-blow fuse to prevent unnecessary fuse failure during pump start-up. Within five 

minutes, as the oil in the pump warms up, the current drawn will slowly reduce to the full load current specified in 

Tables 9 and 10.

2.7 Electrical data: three-phase pumps 

A652–01–880 Issue S 

The dual-voltage, dual-frequency motor is designed for a three-phase electrical supply and is suitable for 50 Hz or 

60 Hz operation. The motor can be manually switched between nominal supply voltages of 220–240 V and 380–460 V 

(refer to Section 3.8.1). Pumps are supplied preset for nominal 380–460 V electrical supplies. 

When you start a cold pump, the motor will draw the start-up current shown in Table 11 for up to 0.5 seconds. The 

current will then reduce quickly as the motor reaches rated rotational speed. Within 5 minutes, as the oil and pump 

warms up, the current drawn will slowly reduce to a maximum of the full load current specified in Table 11. 

When you start a warm pump, the motor will draw the start-up current shown in Table 11 for up to 0.5 seconds. The 

current drawn will then immediately fall to a maximum of the full load current. 

Electrical short-circuit and ground-fault protection of the pump will be provided by fitting Class CC fuses of the values 

shown in Table 11 at the point of connection to the supply. If these are not available in your country of use, Type aM 

European fuses of the same rating can also be used.

3.1 Safety 

WARNING 

A652–01–880 Issue S 

We recommend that you do not use a hydrocarbon-prepared RV pump for pumping hazardous 

substances. PFPE-prepared pumps are suitable for oxygen applications: refer to Section 8. 

You must ensure that the RV pump is suitable for your application. If you have any doubt as to the suitability of the 

RV pump for your application, refer to the Edwards guidelines on vacuum pump and vacuum system safety (see the 

Associated publications at the end of the Contents list at the front of this manual). 

A suitably trained and supervised technician must install your RV pump. Obey the safety instructions listed below 

when you install the pump, especially when you connect the pump into an existing system. Details of specific safety 

precautions are given at the appropriate point in the instructions. 

� Wear the appropriate safety-clothing when you come into contact with contaminated components. 

� Vent and purge your vacuum system before you start installation work. 

� Ensure that the installation technician is familiar with the safety procedures which relate to the pump-oil 

and the products handled by the pumping system. Take suitable precautions to avoid the inhalation of oil 

mist and excessive skin contact with pump-oil, as prolonged exposure can be harmful. 

� Disconnect the other components in the pumping system from the electrical supply so that they cannot be 

operated accidentally. 

3.2 System design considerations 

Consider the following points when you design your pumping system: 

� Use a suitable valve to isolate the pump from your vacuum system if you need to allow the pump to warm up 

before you pump condensable vapours, or to provide additional system protection when the pump is 

switched off. 

� Avoid high levels of heat input to the pump from the process gases, otherwise the pump may overheat and 

seize, and cause the motor thermal overload device to open. 

� If you use the pump in a high ambient temperature and have a high gas throughput, the temperature of the 

pump-body may exceed 70°C and you must fit suitable guards to prevent contact with hot surfaces. 

� Make sure that the exhaust pipeline cannot become blocked. If you have an exhaust-isolation valve, make 

sure that you cannot operate the pump with the valve closed. 

� Provide for a purge of inert gas when you shut down the pumping system, to dilute dangerous gases to safe 

concentrations. A suitable gas ballast adaptor for introduction of purge gas into the pump is available as an 

accessory (see Section 7.4.8). 



Installation

Installation 

A652–01–880 Issue S 

3.3 Unpack and inspect 

1. Remove all packing materials, and remove the pump from its packing-box. 

2. Remove the protective covers from the inlet and outlet-ports and inspect the pump. If the pump is damaged, 

notify your supplier and the carrier in writing within three days; state the Item Number of the pump together 

with your order number and your supplier’s invoice number. Retain all the packing materials for inspection. Do 

not use the pump if it is damaged. 

If the pump is not to be used immediately, replace the protective covers. Store the pump in suitable conditions, as 

described in Section 6.1. 

3.4 Locate the pump 

The RV3 and RV5 pumps have a lifting handle which you can use to move the pump by hand. If you wish to use 

mechanical lifting equipment, do not attach the equipment to the handle; for stability, use slings around the motor 

and the pump-body. 

Do not lift the RV8 and RV12 pumps by hand; attach your mechanical lifting equipment to the lifting bracket on the 

pump. You do not need to use slings to move the RV8 and RV12 pumps. 

Provide a firm, level platform for the pump. Locate the pump so that the oil-level sight-glass is visible and the oil 

filler-plug, oil drain-plug, mode selector and gas-ballast control are accessible. 

If your pump will be located inside an enclosure, make sure that there is adequate ventilation at both ends of the 

pump, so that the ambient temperature around the pump does not exceed 40°C. There must be a minimum space of 

25 mm between the pump and the enclosure walls. 

3.5 Fill the pump with oil 

Fill the pump with oil as described below. Refer to Section 2.5 for the recommended oil. Refer to Figure 1 for the 

item numbers in brackets. 

1. Remove one of the oil filler-plugs (6) 

WARNING 

Use suitable lifting equipment to move the RV8 or RV12 pump. 

The mass of the RV8 and RV12 pumps is approximately 26 kg. 

WARNING 

You must not use a hydrocarbon-prepared pump to process oxygen in concentrations greater than 

25 % in volume. If you do, there is a risk of fire or explosion in the oil-box of the pump. 

PFPE-prepared pumps are available: refer to Section 8. 

2. Pour oil into the pump until the oil-level just reaches the MAX mark on the bezel at the top of the sight-glass (8). 

If the oil-level goes above the MAX mark, remove the drain-plug (9) and drain the excess oil from the pump. 

3. After a few minutes, recheck the oil-level. If the oil-level is now below the MAX mark, pour more oil into the 

pump. 

4. Refit the oil filler-plug. Tighten the plug firmly by hand. Do not overtighten. 



3.6 Fit the motor (bareshaft pumps only) 

If you have a bareshaft pump, fit the motor to the pump now: refer to Section 9. 

3.7 Electrical installation: single-phase pumps 

3.7.1 Check and configure the motor 

CAUTION 

A652–01–880 Issue S 

Ensure that the motor is correctly configured for your electrical supply. If you operate the pump when the motor 

is not correctly configured for the electrical supply, you will damage the motor. 

Refer to Figure 4 for the item numbers in brackets. 

Ensure that the voltage shown on the voltage indicator (4) in the motor-cover corresponds with your electrical supply 

voltage. If it does not, you must change the configuration of the pump-motor to match your electrical supply voltage; 

use the procedure below. 

1. Undo the four screws, remove the cover-plate (1) and lift out the voltage indicator moulding (4). 

2. Press the voltage selector switch (3) to select the alternative position. 

3. Turn the voltage indicator moulding over so that the outer panel shows the required voltage. Refit the moulding. 

4. Refit the cover-plate and secure it with the four screws. 

3.7.2 Connect the pump to your electrical supply 

WARNING 

Ensure that the electrical installation of the RV pump conforms with your local and national safety 

requirements. It must be connected to a suitably fused and protected electrical supply and a 

suitable earth (ground) point. 

Notes: In the UK, if you use a 13 A plug, it must comply with BS1363A and be fitted with a 13 A fuse which 

complies with BS1362. 

To prevent automatic restart of the pump-motor if the electrical supply is restored after an electrical 

supply failure, connect the pump to the electrical supply through suitable control equipment which 

must be reset manually after an electrical supply failure. 

Make the electrical connections to the pump-motor with an IEC 320 cable socket (cold condition type) 

that satisfies your local electrical standards. 

To maintain compliance with CSA standards, you must only use CSA/UL certified electrical supply cables 

and connectors. Cables must be SJT rated (minimum) and must incorporate an earth conductor. The 

conductors in the cable must be a minimum of 18 AWG. The temperature rating of the cable must be 

70°C or greater. 



Installation

Installation 

A652–01–880 Issue S 

If your RV pump was supplied with an electrical supply cable, the cable will be fitted with a moulded IEC connector 

at one end. The other end of the cable may be fitted with a plug suitable for your local electrical supply. A cable 

without a plug will contain wires colour coded as follows: 

Colour Use 

Green and yellow Earth (ground) 

Blue Neutral 

Brown Live 

1. Ensure that the on/off switch on the motor (Figure 4, item 5) is in the ‘off’ position. 

2. Insert the moulded IEC connector at the end of the cable into the electrical inlet-connector on the motor 

(Figure 4, item 2). 

3. Connect the plug (if fitted) at the other end of the cable to your electrical supply. If a plug is not fitted, connect 

the wires in the cable to the correct terminals of your electrical supply. 

3.7.3 Check the direction of rotation 

CAUTION 

Ensure that the pump-motor rotates in the correct direction. If it does not, the pump and your vacuum system 

can become pressurised. 


1. Watch the motor cooling-fan through the motor fan-cover (13). 

2. Use the on/off switch (12) to switch-on the electrical supply to the motor for a few seconds. 

3. Check that the motor cooling-fan rotates in the correct direction (14) shown by the arrow on the motor 

fan-cover. If the direction of rotation is incorrect, switch off the electrical supply immediately and contact your 

supplier or Edwards for advice.

3.8 Electrical installation: three-phase pumps 

3.8.1 Check and configure the motor 

CAUTION 

Ensure that the motor is correctly configured for your electrical supply. If you operate the pump when the motor 

is not correctly configured for the electrical supply, you will damage the motor. 

1. Remove the screws which secure the cover of the motor terminal-box. Remove the cover. 

2. Remove the cable-gland from the inside of the terminal-box and fit the cable-gland to the cable leadthrough 

hole in the side of the terminal-box. 

3. Ensure that the motor is correctly configured for your electrical supply. If necessary, reconfigure the links 

(Figures 5 and 6, item 1) to suit your electrical supply: 

� For 200–230 V electrical supplies, the links must be configured as shown in Figure 5. 

� For 380–460 V electrical supplies, the links must be configured as shown in Figure 6. 

3.8.2 Connect the pump to your electrical supply 

WARNING 

Ensure that the electrical installation of the RV pump conforms with your local and national safety 

requirements. It must be connected to a suitably fused and protected electrical supply and a 

suitable earth (ground) point. 

Notes: To prevent automatic restart of the pump-motor if the electrical supply is restored after an electrical 

supply failure, connect the pump to the electrical supply through suitable control equipment which 

must be reset manually after an electrical supply failure. 

To maintain compliance with CSA (Canadian Standards Association) standards, you must incorporate a 

switch or circuit breaker in the pump electrical supply. The switch or circuit breaker must be close to 

the pump and easily accessible, and must be clearly marked to identify that it is the electrical supply 

disconnection device for the pump. 

We recommend that you connect the electrical supply to the motor through a starter or circuit breaker which has 

thermal over-current protection which can be adjusted to suit the full load current ratings shown in Table 11. The 

fuse ratings in Table 11 are provided for guidance only. The supplier of your thermal over-current protection device 

may specify different values to ensure correct operation of the fuse and the over-current protection device. Ensure 

that the fuse you use is suitable for the starting currents given in Table 11. 

1. Pass the electrical supply cable through the cable-gland. The diameter of the electrical supply cable should be 

in the range 7to11mm. 

2. Use insulated crimped connectors to connect the wires in the cable to the terminals U1, V1 and W1 and Earth 

(ground) in the terminal-box as shown in Figures 5 and 6. You must tighten the earth (ground) terminal 

connection to a torque of 2.13 to 2.87 Nm. 

3. Ensure that the cover gasket is correctly positioned, then refit the cover to the terminal-box and secure with the 

screws. Tighten the strain-relief nut on the cable-gland.

3.8.3 Check the direction of rotation 

CAUTION 

Ensure that the pump-motor rotates in the correct direction. If it does not, the pump and your vacuum system 

can become pressurised. 

1. Refer to Figure 1. Watch the motor cooling-fan through the motor fan-cover (13). 

2. Switch-on the electrical supply to the motor for a few seconds. 

3. Check that the motor cooling-fan rotates in the correct direction shown by the arrow on the motor mounting 

plate. If the direction of rotation is incorrect: 

� Switch off the electrical supply immediately. 

� Isolate the pump from the electrical supply. 

� Remove the terminal-box cover and swap wires L1 and L3: see Figures 5 and 6. 

� Refit the cover to the terminal-box. 

3.9 Inlet and outlet connections 

WARNING 

Connect the exhaust to a suitable treatment plant to prevent the discharge of dangerous gases and 

vapours to the surrounding atmosphere. Use a catchpot to prevent the drainage of contaminated 

condensate back into the pump. 

Before you connect the pump to your vacuum system, fit the centring-ring and inlet-filter (supplied with the pump) 

to the pump inlet-port (see Figure 5). 

Take note of the following information when you connect the pump to your vacuum system. Refer to Section 7.4 for 

details of the accessories mentioned below. Use standard NW25 fittings (not supplied) when you connect the pump. 

� For optimum pumping speeds, ensure that the pipeline connected to the pump-inlet is as short as possible 

and has an internal diameter of 25 mm or larger. 

� Support the vacuum pipelines to prevent loading of the coupling-joints. 

� If necessary, incorporate flexible bellows in your system pipelines to reduce the transmission of vibration and 

to prevent loading of coupling-joints. If you use flexible bellows, you must ensure that you use bellows which 

have a maximum pressure rating which is greater than the highest pressure that can be generated in your 

system. We recommend that you use Edwards flexible bellows. 

� Use a suitable inlet trap if you pump condensable vapours or if you use the pump for very dusty applications. 

� Use a suitable valve to isolate the pump from your vacuum system if you need to pump condensable vapours 

or maintain vacuum when the pump is switched off. 

� Ensure that sealing surfaces are clean and scratch-free. 



In any of the following circumstances, we recommend that you fit an oil mist filter to the pump outlet: 

� If you use the pump with the gas ballast control open (in position ‘I’ or position ‘II’). 

A652–01–880 Issue S 

� If you operate the pump with an inlet pressure greater than 10 mbar (1 x 10³ Pa) for extended periods. 

� If you frequently pump down from atmospheric pressure. 

The oil mist filter will trap the oil exhausted from the pump; you can reuse the oil if it is not contaminated. 

3.10 Leak-test the system 

Leak-test the system and seal any leaks found after you have installed the RV pump, to prevent leakage of substances 

out of the system and leakage of air into the system.

4 Operation 

4.1 ATEX directive implications 

4.1.1 Introduction 

A652–01–880 Issue S 

This equipment is designed to meet the requirements of Group II Category 3 equipment in accordance with 

Directive 94/9/EC of the European Parliament and the Council of 23rd March 1994 on the approximation of the laws 

of the Member States concerning equipment and protective systems intended for use in potentially explosive 

atmospheres. (The ATEX Directive) 

The ATEX Category 3 applies in respect of potential ignition sources internal to the equipment. An ATEX Category has 

not been assigned in respect of potential ignition sources on the outside of the equipment as the equipment has not 

been designed for use where there is an external potentially explosive atmosphere. 

There is no potential source of ignition within the pump during normal operation but there may be potential sources 

of ignition under conditions of predicted and rare malfunction as defined in the Directive. Accordingly, although the 

pump is designed to pump flammable materials and mixtures, operating procedures should ensure that under all 

normal and reasonably predicted conditions, these materials and mixtures are not within explosive limits. Category 3 

is considered appropriate for the avoidance of ignition in the case of a rare malfunction which allows flammable 

materials or mixtures to pass through the pump while within their explosive limits. 

4.1.2 Flammable/pyrophoric materials 

When flammable or pyrophoric materials are present within the equipment you must: 

� Not allow air to enter the equipment. 

� Ensure the system is leak tight. 

WARNING 

Do not expose any part of your body to vacuum. If you do, you may be injured. 

WARNING 

You must obey the instructions and take note of the precautions given below, to ensure that 

pumped gases do not enter their flammable ranges. 

� Use an inert gas purge (for example, a nitrogen purge) to dilute any flammable gases or vapours entering the 

pump inlet, and/or use an inert gas purge to reduce the concentration of flammable gases or vapours in the 

pump and in the exhaust pipeline to less than one quarter of the gases’ published lower explosive limits 

(LEL). 

� Use an inert gas purge into the pump gas ballast connection to prevent the condensation of flammable 

vapours within the pump mechanism and exhaust pipeline. 



Operation

Operation 

A652–01–880 Issue S 

4.1.3 Gas purges 

Switch on the inert gas purge to remove air from the pump and the exhaust pipeline before the process starts. Switch 

off the purge flow at the end of the process only after any remaining flammable gases or vapours have been purged 

from the pump and exhaust pipeline. 

If liquids that produce flammable vapours could be present in the pump foreline, then the inert gas purge to the RV3, 

RV5, RV8 and RV12 rotary vane pump should be left on all the time this liquid is present. Flammable liquids could be 

present in the foreline as a result of condensation, or may be carried over from the process. 

When you calculate the flow rate of inert gas required for dilution, consider the maximum flow rate for the 

flammable gases/vapours that could occur. For example, if a mass flow controller is used to supply flammable gases 

to the process, you should assume a flow rate for flammable gases that could arise if the mass flow controller is fully 

open. 

Continually measure the inert gas purge flow rate: if the flow rate falls below that required, you must stop the flow 

of flammable gases or vapours into the pump. 

Note: We recommend that you obtain and read the Vacuum Pump and Vacuum System Safety manual (publication 

number P300–20–000), available from Edwards or your supplier. 

4.2 How to use the pump controls 


WARNING 

If you use inert gas purges to dilute dangerous gases to a safe level, ensure that the RV3, RV5, RV8 

and RV12 rotary vane pump is shut down if an inert gas supply fails. 

WARNING 

You must obey the instructions and take note of the precautions given below, to ensure that 

pumped gases do not enter their flammable ranges. 

You can use the mode selector (Figure 1, item 11) and the gas-ballast control (Figure 1, item 5) to optimise the 

performance of the RV pump for your application. The performance characteristics of the pump with the different 

control settings are shown in Tables 3 and 4. You can change the position of both the mode selector and the 

gas-ballast control when the pump is off or when the pump is operating. 



4.2.2 Mode selector 

A652–01–880 Issue S 

Note: The pump is supplied with High Vacuum mode � selected. If High Vacuum mode is selected and you cannot 

turn the mode selector by hand to select the High Throughput mode, use a suitable tool fitted to the flat 

part of the mode selector to turn the selector. 

The mode selector controls the flow of pressurised oil to the high vacuum stage of the pump (see Section 1.4.1). You 

can turn the mode selector to one of two positions, as follows: 

To select the High Vacuum mode �, turn the mode selector fully clockwise and tighten by hand. When High Vacuum 

mode is selected, there is a gap of approximately 3 mm between the mode selector and the inner face of the side 

panel of the pump. Use this mode: 

� to achieve ultimate vacuum 

� to pump clean gases 

� to pump clean condensable vapours. 

To select the High Throughput mode �, turn the mode selector fully anticlockwise until it touches the inner face of 

the side panel of the pump, then gently tighten by hand. Use this mode: 

� for long-term operation with high gas throughput (that is, inlet pressure > 50 mbar) 

� to pump dirty condensable vapours 

� to decontaminate the oil. 

4.2.3 Gas-ballast control 

Use the gas-ballast control to change the amount of air (or inert gas) introduced into the low vacuum stage of the 

pump (refer to Section 1.4.2). Use of gas-ballast will prevent the condensation of vapours in the pump; the 

condensates would contaminate the oil. You can turn the gas-ballast control to select one of three positions, as 

follows: 

To select gas-ballast closed, turn the control to position ‘0’. Use this setting: 

� to achieve ultimate vacuum 

� to pump dry gases. 

To select low flow gas-ballast, turn the control to position ‘I’. Use this setting: 

� to pump low concentrations of condensable vapours 

� to decontaminate the oil. 

To select high flow gas-ballast, turn the control to position ‘II’. Use this setting: 

� to pump high concentrations of condensable vapours. 

When you use either low flow or high flow gas-ballast, there will be an increased rate of oil loss from the pump. 

Where possible, we recommend that you select low flow gas-ballast (position ‘I’) rather than high flow gas-ballast 

(position ‘II’) to minimise the loss of oil. 





A652–01–880 Issue S 

4.3 Start-up procedure 

If the oil is contaminated, or if the pump temperature is below 12°C, or if the electrical supply voltage is more than 

10% below the lowest voltage specified on the voltage indicator (Figure 4, item 4), the pump may operate at a 

reduced speed for a few minutes. On single-phase pumps, if the pump continues to operate at reduced speed, the 

motor thermal overload device will open and stop the pump. When the motor has cooled, the thermal overload device 

will reset automatically and the pump will restart. 

1. Check that the pump oil-level is between the MAX and MIN marks on the bezel of the oil-level sight-glass; if it is 

not, refer to Section 5.3. 

2. Turn the mode selector fully clockwise to select High Vacuum mode � or fully anticlockwise to select High 

Throughput mode �, as required (refer to Section 4.2.2). 

3. Turn the gas-ballast control to position ‘0’, ‘I’ or ‘II’, as required (refer to Section 4.2.3). 

4. Switch on the electrical supply to the pump; on single-phase pumps, use the on/off switch. 

5. If you want to achieve ultimate vacuum, to pump condensable vapours or to decontaminate the pump oil, refer 

to the procedures in Sections 4.4, 4.5 and 4.6 respectively. Otherwise, open the vacuum system isolation-valve. 

4.4 To achieve ultimate vacuum 

If the pump does not achieve the performance specified in Section 2.2, make sure that this is not due to your system 

design before you contact your supplier or Edwards for advice. In particular, the vapour pressure of all materials used 

in your vacuum system (including pump oil, see below) must be much lower than the specified ultimate vacuum of 

the pump. Refer to Section 5.12.3 for a list of possible causes for failure to achieve the specified performance; note 

however that the most common causes are: 

� Your pressure measurement technique or gauge head is unsuitable or the gauge head is faulty. 

� You have used an oil other than the recommended oil, and the vapour pressure of the oil is higher than the 

specified ultimate vacuum of the pump. 

Use the following procedure to achieve ultimate vacuum: 

1. Isolate the RV pump from your vacuum system. 

WARNING 

Ensure that your system design does not allow the exhaust pipeline to be blocked. 

2. Turn the mode selector to select High Throughput mode �, set the gas-ballast control to low flow (position ‘I’) 

and operate the pump for at least 1 hour (or overnight) to thoroughly purge the oil of contaminants. 

3. Turn the mode selector to select High Vacuum mode � and close the gas-ballast control (that is, set it to 

position ‘0’). 

Open the vacuum system isolation-valve and pump down to ultimate vacuum. 



4.5 To pump condensable vapours 

A652–01–880 Issue S 

Use gas-ballast (gas-ballast control in position ‘I’ or ‘II’) when there is a high proportion of condensable vapours in 

the process gases. 

1. Close the vacuum system isolation-valve. 

2. Turn the mode selector fully clockwise to select High Vacuum mode � or fully anticlockwise to select High 

Throughput mode �, as required (refer to Section 4.2.2). 

3. Turn the gas-ballast control to high flow (position ‘II’) and operate the pump for 30 minutes to warm the oil; this 

will help to prevent vapour condensation in the pump. 

4. Set the gas-ballast control to the position required for your application (refer to Section 4.2.3 and the data in 

Tables 3 and 4). 

5. Open the vacuum system isolation-valve. 

After you have pumped condensable vapours, you can (if necessary) decontaminate the oil: use the procedure in 

Section 4.6. 

4.6 To decontaminate the oil 

The oil in the pump should be clear; if the oil is cloudy or discoloured, it is contaminated with process vapours. 

1. Look at the condition of the oil in the oil-level sight-glass (Figure 1, item 8). If the oil is cloudy or discoloured, 

continue with the procedure at Step 2 below. 

2. Close the vacuum system isolation-valve. 

3. Turn the mode selector fully anticlockwise to select High Throughput mode �. Set the gas-ballast control to low 

flow (position ‘I’). 

4. Operate the pump until the oil is clear. 

4.7 Unattended operation 

The RV pump is designed for unattended operation under the normal operating conditions specified in Section 2.1. 

However, we recommend that you check the pump at regular intervals of not more than 14 days, or more frequently 

if you pump high volumes of gas or vapour. 

On single-phase pumps, the motor is protected by an overload device which isolates the pump from the electrical 

supply when critical temperature or current levels are exceeded. The overload device resets automatically when the 

motor has cooled. When you check the pump, make sure that the pump is not going through a repetitive cycle of 

thermal overload failures and automatic resets. If necessary, change the mode selector to High Throughput mode � 

and reduce the thermal load from the pumped gases, to prevent overheating of the pump. 





A652–01–880 Issue S 

4.8 Shut-down 

We recommend, as described in the procedure below, that you decontaminate the oil before you shut down the 

pump; this will prevent damage to the pump by the contaminates in the oil. 

1. Refer to Section 4.6 and decontaminate the oil, as required. 

2. Close the vacuum system isolation-valve (if not already closed). 

3. Close gas-ballast (that is, set the gas-ballast control to position ‘0’). 

4. On single-phase pumps, use the on/off switch to switch off the pump. 

5. Switch off the electrical supply to the pump. 



5 Maintenance 

5.1 Safety information 

WARNING 

A652–01–880 Issue S 

Obey the safety instructions given below and take note of appropriate precautions. If you do not, 

you can cause injury to people and damage to equipment. 

� If your pump is PFPE-prepared, refer to Section 8 before you maintain the pump. 

� A suitably trained and supervised technician must maintain the pump. Obey your local and national safety 

requirements. 

� Ensure that the maintenance technician is familiar with the safety procedures which relate to the pump-oil 

and the products processed by the pumping system. 

� Check that all the required parts are available and of the correct type before you start work. 

� Isolate the pump and other components from the electrical supply so that they cannot be operated 

accidentally. 

� Allow the pump to cool (so that it is at a safe temperature for skin contact) before you start maintenance 

work. Make sure the pump is switched off in case the thermal overload device restarts the pump. 

� Do not reuse ‘O’ rings and seals if they are damaged. 

� After maintenance is completed, recheck the direction of pump rotation if the electrical supply has been 

disconnected. 

� The pump and the pump-oil will be contaminated with the process chemicals that have been pumped during 

operation. Ensure that the pump is decontaminated before maintenance and that you take adequate 

precautions to protect people from the effects of dangerous substances if contamination has occurred. 

� Do not touch or inhale the thermal breakdown products of fluorinated materials which may be present if the 

pump has been heated to 310°C and above. Fluorinated materials are safe in normal use but can decompose 

into very dangerous substances (which may include hydrofluoric acid) if they are heated to 310°C and above. 

The pump may have overheated if it was misused, if it malfunctioned, or if it was in a fire. Material Safety 

Data Sheets for fluorinated materials used in the pump are available on request: contact your supplier or 

Edwards.

A652–01–880 Issue S 

5.2 Maintenance plan 

The plan shown in Table 12 details the routine maintenance operations necessary to maintain RV pumps in normal 

use. Instructions for each operation are given in the section shown. 

More frequent maintenance may be required if the pump is used to pump corrosive or abrasive gases and vapours, 

such as solvents, organic substances and acids; in these circumstances, we recommend that you replace the pump 

seals every year (refer to Section 7.3 for details of available spares). If necessary, adjust the maintenance plan 

according to your experience. 

When you maintain the RV pump, use Edwards spares and maintenance kits; these contain all of the components 

necessary to complete maintenance operations successfully. The Item Numbers of the spares and kits are given in 

Section 7.3. 

5.3 Check the oil-level 

Note: If required, you can check the oil-level while the pump is operating, however you must switch off the pump 

and isolate the pump and other components in the pumping system from the electrical supply before you 

pour oil into the pump. 

Refer to Figure 1 for the items in brackets.

the reservoir until the oil reaches the MAX level mark. If the oil-level goes above the MAX mark, remove the 

drain-plug (9) and drain the excess oil from the pump. Refit the filler-plug. 

3. If the oil is contaminated, drain and refill the pump with clean oil as described in Section 5.4. 



5.4 Replace the oil 

A652–01–880 Issue S 

1. Refer to Figure 1. Operate the pump for approximately ten minutes to warm the oil, then switch off the pump 

(this lowers the viscosity of the oil and enables it to be drained from the pump more easily). 

2. Isolate the pump from your electrical supply and disconnect it from your vacuum system. 

3. Remove one of the oil filler-plugs (6). 

4. Place a suitable block under the pump-motor to tilt the pump and place a suitable container under the 

drain-plug (9). Remove the drain-plug and allow the oil to drain into the container. 

5. If the oil drained from the pump is contaminated, pour clean oil into the filler-hole and allow it to drain out of 

the pump. Repeat this step until the oil reservoir in the pump has been thoroughly cleaned. 

6. Refit the drain-plug, remove the block and reconnect the pump to your vacuum system. 

7. Fill a suitable container with clean oil and pour the oil into the filler hole until the oil-level reaches the MAX 

level mark on the bezel of the sight-glass (8). 

8. Allow a few minutes for the oil to drain into the pump. If necessary, add more oil. Refit the filler-plug. 

5.5 Inspect and clean the inlet-filter 

1. Refer to Figure 7. Disconnect your vacuum system from the pump inlet-port (3) and remove the centring-ring 

and filter assembly (1) and the ‘O’ ring (2). Inspect the centring-ring and the ‘O’ ring. If they are clean, continue 

at Step 5. If they are not clean, continue at Step 2. 

2. Remove the ‘O’ ring (2) from the centring-ring and filter assembly (1). Do not allow the ‘O’ ring to come into 

contact with the cleaning solution. 

3. Wash the centring-ring and filter assembly in a suitable cleaning solution and allow it to dry. 

4. If necessary, wipe the ‘O’ ring with a clean, dry, lint-free cloth. 

5. Refit the centring-ring and filter assembly and the ‘O’ ring to the inlet-port. Refit your vacuum system to the 

pump inlet-port.

8 PFPE-prepared RV pumps 

8.1 Summary 

A652–01–880 Issue S 

If you have ordered a PFPE-prepared RV pump, the pump will be supplied prepared for use with Edwards PFPE 

mechanical pump oils, such as Fomblin YVAC 06/6 and Krytox 1506. 

PFPE-prepared RV pumps are suitable for pumping high concentrations of oxygen. 

We recommend that you refer to Edwards publication P300–20–000 (Vacuum pump and Vacuum System Safety) before 

you install and use a PFPE-prepared RV pump. 

8.2 Installation 

CAUTION 

Never use hydrocarbon lubricants in a PFPE-prepared pump. 

When you fill the RV pump with oil (as described in Section 3.5), you must use a suitable Edwards PFPE oil. You must 

not use a hydrocarbon oil. 

8.3 Operation 

Operation of a PFPE-prepared RV pump is as specified in Section 4, but take note of the warning above. 

8.4 Maintenance 

WARNING 

PFPE-prepared RV pumps are suitable for pumping high concentrations of oxygen, but we 

recommend that you do not use a PFPE-prepared RV pump for the pumping of hazardous materials. 

WARNING 

Obey the safety instructions given below and take note of appropriate precautions. If you do not, 

you can cause injury to people. 

� Take additional care if you suspect that the pump (and hence the PFPE oil) has overheated. 

� Do not touch or inhale the thermal breakdown products of PFPE oil which may be present if the pump has 

been heated to 260°C and above. PFPE oils are safe in normal use but can decompose into very dangerous 

substances if they are heated to 260°C and above. The pump may have overheated if it was misused, if it 

malfunctioned, or if it was in a fire. Material Safety Data Sheets for PFPE oils used in the pump are available 

on request: contact your supplier or Edwards. 

Fomblin oil has different properties from other pump oils, therefore: 

� If you fill your PFPE-prepared RV pump with Fomblin oil, we recommend that you regularly check for oil 

leaks, particularly around the shaft seals. 

� If you detect an oil leak, contact your supplier or Edwards for advice.
