All the information in this manual must be read and understood before system installation or 

maintenance. 

Pay particular attention to the manual sections with note WARNING: 

the non observance of that notes can cause damage to the persons and/or equipments. 


Page 3 of 29

1. PURPOSE 

SANCO 


The purpose of this manual is to provide the installer with the necessary information required for 

correct assembly of the systems and special apparatus, and furthermore, information regarding the 

inspections to be carried out and tests to be executed on the systems before being made available for 

use. 

This manual has also the scope to give the contractor or user the information necessary for the 

installation, preliminary and final verification, before the start-up of the system or of the special 

equipment supplied, and furthermore, information regarding the system maintenance. 

As this manual is not specific for type of system or equipment supplied, we have 

considered the common parts, recognizable in similar situations, with reference to other documents in 

which the characteristics of the components used are clearly described, as well as all the other 

information necessary for the installation and verification. 


Page 4 of 29

2. HEALTH AND SAFETY 

2.1. SAFETY REQUIREMENTS 

SANCO 


Safety rules to be observed during the assembling and maintenance are those indicated by 

regulations in force, all further regulations prescribed by the purchaser or by the Authorities having 

jurisdiction and also, where applicable, European safety directive (Machinery directive 37/98, 

PED97/23, ATEX 94/9, EMC 89/336, low voltage 73/23). 

2.2. GAS TOXICITY 

The supplied fire - fighting system uses the carbon dioxide as an extinguishing agent. This normally 

appears in the form of odourless and colourless gas which, through rapid and severe expansion, will 

produce both a fall in temperature (because it is capable of evaporating quickly without leaving 

residue) and a reduction in the percentage of oxygen below the values which allow combustion. 

Carbon dioxide insulates more than air and does not corrode or damage any material. 

Carbon dioxide, which remains within a location, can be easily removed by airing or by mechanical 

ventilation because it is heavier than simple air. 

Due to the fact that a man can not breathe without difficulty in a room where carbon dioxide is present 

in any concentration higher than 3.5%, it is important to be extremely careful on entering a room in 

which even a small amount of gas has been released. Therefore, the use of breathing apparatus is 

very important. 

If a person should show symptoms of carbon dioxide suffocation, it is necessary to take that person 

out of the location immediately, then artificial respiration should be administered, like it would be in the 

case of drowning, oxygen has to be given in order to achieve revival. Carbon dioxide which remains 

within a location can be easily removed by airing or by mechanical ventilation because it is heavier 

than air. 

These operations should be carried out in the presence of a doctor. 

2.3. CO2 CYLINDERS DANGER 

Pressurized (charged) cylinders are extremely hazardous and, if not handled properly, are capable of 

violent discharge. This may result in serious bodily injury or property damage ; always handle carbon 

dioxide cylinders with care. Cylinders are factory equipped with a protection cap. This device is a 

safety feature and provide protection during handling. 

Do not move or handle a carbon dioxide cylinder unless the protection cap and the valve safety pin 

are installed. For cylinder installation and removing see the relative paragraphs. 

2.4. ELECTRIC SAFETY 

The supplied fire - fighting system has a power supply for electrical equipments. 

During any operation of assembly and maintenance for any electrical equipments, the system isolation 

from power supply is mandatory.

3. GENERAL NOTES REGARDING CARBON DIOXIDE 

3.1. CO2 SYSTEMS FIELD APPLICATION 

Carbon dioxide can be used to extinguish fires caused by: 

- inflammable liquids (class B fires) and materials reacting in a similar way to fire exposures, i.e. give 

surface fires 

- inflammable gases (C class fires); in that case you need to check that after the extinction there is no 

formation of explosive atmosphere because of unburnt gas leaks 

- devices and electrical systems under tension 

- wood, paper, cloth, etc. (A class fires); normally in these cases a great quantity of CO2 and a long 

permanence of the same in atmosphere are necessary to allow for the slow decreasing of ambient 

temperature and of embers 

With CO2 there is no extinction of fires caused by: 

- products containing the oxygen necessary for combustion 

- metals and chemical products reacting to CO2, such as alkaline metals and titanium 

Extinguishing action of carbon dioxide is based upon the reduction of the concentration of oxygen in 

the air down to a level preventing combustion, at the same time the cooling caused by carbon dioxide 

discharge contributes, as a secondary effect, to extinction. 

After discharging it may be necessary to keep carbon dioxide in the environment even once the fire 

has been extinguished, in order to allow for the various objects to cool down and avoid new fires 

starting. 

The carbon dioxide at environmental conditions is at gaseous state, consequently it is used into closed 

rooms where the gas loss is moderate. It can be, however, used for the protection of open areas, by 

adopting proper techniques.

4. CO2 SYSTEMS GENERAL DESCRIPTION 

The following systems described were installed for fire - fighting protection of areas which have 

electrical apparatus and/or live wires, by means of high pressure type carbon dioxide systems. 

The system, of the fixed type, is made up of piping normally empty, connected to a set of CO2 storage 

cylinders. 

Nozzles of the open type, distributed and orientated in accordance with the applicable standards 

installed onto the piping, release the gas within the protected area to contain and extinguish the fire. 

The intervention of the system is activated automatically by means of the fire detection system which 

will power up the electric controls located on the pilot cylinder, and/or manually, on site, by means of 

suitable handle controls acting exclusively on the pilot cylinder of the CO2 storage set. 

The intervention of the pilot cylinder will control the opening of all other slave cylinders. 

The release of gas will activate, by means of a pressure device, the alarm signals, which will then be 

displayed as the intervention on the control panel. 

4.1. CO2 CYLINDERS UNIT 

The fire is extinguished thanks to the release within the protected areas of a calculated quantity of 

carbon dioxide stored on cylinders placed in a safe position, on a suitable rack. 

The quantity of carbon dioxide is calculated in accordance with Regulation number 12 of The 

American National Fire Protection Association (NFPA) and based upon the specific requirement of the 

project 

The cylinders are made of special carbon steel and tested up to 250 Kg. / cm 2 . 

Every cylinder is equipped with a special quick release valve and siphon, and complete with a safety 

disk against over-pressure. 

The bursting pressure of the safety disk is equal to 250 bar. 

Each cylinder is further provided with a mechanical weighing device, which indicates that the contents 

of the cylinders are max. 10% below their nominal charge. 

All the cylinders are connected to a manifold by means of flexible hoses. On the connections of the 

manifold, suitable check valves are installed. 

These allow the performance of the system even in the case of one or more disconnected cylinders 

for maintenance purposes. 

For cylinder unit controlled with pneumatic devices, the pilot cylinder check valves are supplied with a 

lateral coupling, for the connection of the pressurisation circuit of the pneumatic operator which 

controls the intervention of the system of levers of all the slave cylinders. 

4.2. DISTRIBUTION NETWORK 

The distribution network is made of piping of calculated thickness to cope with the pressure of the 

gas, connected by means of fittings junctions. 

Discharge nozzles, supplied with purposely calculated drills, are installed onto the piping in the ideal 

position. 

The quantity and the location of these nozzles are established according to the type of protection, the 

discharge time and the characteristics of the area and/or the protected equipment. 

4.3. FIRE DETECTION AND FIRE ALARM SYSTEM 

In the protected areas, for quick signalling and a subsequent immediate intervention, fire detection 

systems with smoke, gas or heat detectors are installed. 

The systems are controlled by main control panel located in the FIRE FIGHTING ROOM. 

In the field, near particular zone specified in the project, are placed several fire alarm devices as 

horns and flashing lamps to warning the personnel to evacuate immediately the area; moreover others 

devices as push buttons, are placed for a manual alarm call, manual discharge or shutdown function. 

Often, in proximity of the protected areas accesses, CO2 system status panels are installed to warning 

the personnel related to the CO2 system operations (ex. System “Auto” , “Inhibited” , “CO2 Discharge”). 

For the description of these systems see the relevant manual. 


Page 8 of 29

4.4. SYSTEM OPERATION 

SANCO 


The automatic intervention of the system is activated by a detection system which will actuate by 

means of the electrical control the pilot cylinders and consequently the beginning of the gas discharge 

(the start discharge is normally delayed of 30 seconds). 

Part of the gas, by means of the pneumatic circuit of the check valve, will pressurise the pneumatic 

pistons; these ones, by means of their levers pull the opening control bars of all the interested 

cylinders. 

The actuation manual control by means of a push button will follow the above described logic of 

intervention. 

To signal the intervention of the system, on the discharge pipe is installed a pressure device (normally 

a pressure switch with manual reset), connected to the system alarm panel. 

For the emergency manual mechanical control, it is necessary to proceed as follows: 

- act on the pull handle on the cylinder rack, causing the immediately intervention and the gas 

discharge. 

WARNING: Before actuate the intervention devices, be sure that nobody is in the protected 

zone or it the nearby or communicant zones . 

The gas discharge is extremely dangerous for the people which should inhale it or for the 

rescuers if not provided with breathing apparatus. 

CARBON DIOXIDE GAS CAN CAUSE INJURY OR DEATH.

order to verify the tightness of the couplings and the integrity of the components. The test pressure will 

be about 3 bar. The period of the test will be at least 10’. Longer periods will be expressly indicated on 

the project documents. 

• A test pressure decrease within 20% after 10’ will be acceptable. 

During the test possible leakage will be verified. They will have to be eliminated and the test will have 

to be repeated till the relevant result will be positive. 

The cut-off valves must be closed and instead of the nozzles, caps will be assembled. 

The verification can be carried out in different system section, in case the system is particularly 

extended or in case some particular considerations are necessary.

SANCO 


• At the end of the pneumatic test, removing all the caps and carry out the blowing of the piping by 

means of inlet of compressed air or nitrogen. 

The flow must have the direction from control unit to nozzles. 

Clean any obstructed connection and all the dirty traps at the end of the pipe line, even if partially, 

before reinstalling the nozzles. 

At the end of the operation install the nozzles, taking care that all the couplings are tightened. 

REMARK: the CO2 system include a variety of discharge nozzles, each designed for a specific 

application or flow rate: all nozzles have discharge orifices drilled to suit the specific nozzle location 

and discharge flow requirements (see the stamped values on each nozzle). 

When installing nozzles, it is imperative that the correct nozzle be installed in its appropriate location 

within the system discharge piping network (refer to the CO2 piping layout drawing to find the exactly 

location of each nozzle): the not respect of such indications involve a not corrected discharge 

inside the specified protected area. 

c) Whole system: 

• Check that the installation is complete and that the nozzles and the special components have been 

correctly placed. 

Issue test reports indicating that the final operations have been carried out. The documents should be 

complete with the registered data, the date and the name of the persons who took part in the 

operations. 

7.7. FINAL CHECK 

a) Cylinders units : 

• Verify that the structures are well fixed both among them and to the floor, the counterweight of 

weighing devices are locked between the relevant nuts and lock nuts, the pneumatic circuits are 

connected and couplings well closed. 

• Verify that all electric equipment are correctly connected, but that the relevant control panels are 

not energized. 

For all operations of test of the control and signaling circuits, refer to the relevant manuals. 

b) Distribution system 

• Verify that the pipes are completely assembled and connected and supports are well fixed on the 

structures, walls and ceilings; the discharge nozzles are installed in its appropriate locations and 

supplied with protecting screen. 

c) Protected area : 

• Verify that all pipes passing through walls and ceilings are sealed; all openings, that are not 

considered in the system calculations, are sealed or supplied with automatic closing devices; the 

existence of all warning intervention devices to evacuate the protected area. 

d) Whole system 

• Carry out the test operations as below described, in order to verify, where possible, the correct 

working of the equipment before the possible “START UP”. 


Page 19 of 29

8. TEST PROCEDURE 

SANCO 


At the end of the control operations previously described, proceed with the hereunder listed test 

operations. 

8.1. FUNCTIONAL TEST 

Carry out the functional test of the different components in order to make sure of their working, without 

causing the intervention of the extinguishing systems but only the activation of signaling and control 

devices, connected to the different components or controlled by them. 

• Test the pressure switch pushing in the internal piston 

(see relevant manual for others pressure devices as pressure transmitters). 

• Test the electromechanical controls with lever extension of pilot cylinder valves disconnected 

from the same valves, in order to verify their activation by means of an electric impulse controlled 

by the relevant control panel. 

• Check the intervention of the weighing switches, by putting up cylinders lightly, till they will operate. 

• Check the correct function of other devices if any (cut-off valve limit switches, selector switches, 

etc.) 

8.2. OPERATIONAL TEST 

As per NFPA12 requirements, each carbon dioxide system must be tested with full gas discharge in 

order to make sure that the project characteristics are observed, causing the intervention of the 

systems with the distribution of the extinguishing agent in the considered area. 

For this test we suggest to contact a Fire Fighting Company or equivalent agency, agreed with 

authority having jurisdiction. 

The execution of the test must be entrusted to trained personnel, who are also provided with all 

necessary safety equipment. 

All CO2 systems testing should successfully accomplish the following: 

• Check the integrity of the piping distribution including cylinders rack, supports and anchors. 

• Verify detector operation. 

• Verify audible and/or visual alarm operation. 

• Verify manual release operation. 

• Verify that all interlock and shutdown functions operate and occur at the appropriate time in the 

system discharge sequence. 

• Actuation sequence conforms to the intended design and pre-discharge time delays (if provided), 

operates correctly and with the correct time delay period. 

• All pressure operated devices function as intended at the correct point in the firing sequence. 

• All safety and warning features are in place and operate satisfactorily. 

• Design concentration is attained within the appropriate time in accordance with NFPA 12. 

• Designed concentration levels are attained and remain in the hazard area for the period of time 

specified. The ability to reach and maintain concentration levels is STRICTLY dependent upon the 

construction of the enclosure and measures taken to prevent agent loss. Total flood systems 

perform best when agent loss due leakage from the enclosure is held a minimum. 


Page 20 of 29

SANCO 


REMARK: performing a “Room Integrity Fan Test” is strongly recommended prior to conducting a 

discharge test; this test is “non-destructive” and will help to find the points of possible hazard leakage 

that can be sealed and secured before the discharge test is performed. 

In order to carry out the “OPERATING TESTS”, it will be necessary to complete the assembly of 

extension pilot cylinder levers and the removal of all safety pins of cylinder valves. 

At the end of the test, a final test report has to be issued, signed by all persons representing the firm 

charged with the installation, the purchaser / final customer. 

On the report all data relevant to the test and possible remarks will have to be indicated.

9. SYSTEM OPERATIONS 

9.1. START-UP PROCEDURES 

SANCO 


When the systems are completely tested, as indicate in the above chapters, the following control 

operations must be executed: 

a) Cylinder battery, please check: 

• that the structures are properly fixed, one to the other and to the floor; 

• that the counter weights of the weighing devices are blocked within the relevant nuts and bolts; 

• the pneumatic circuits are properly connected and the fittings properly sealed 

• the electric circuit are connected to the equipment and to the signalling and control system 

• the safety pins are positioned in the valves 

• set and rearm the controls without positioning the lever extensions 

• with the cylinder lever extensions disconnected from the same valve, test the electromechanical 

control with the actuation by means of electrical impulse controlled by the relevant panel 

• lift slowly the cylinder to verify the action of the weighing device and the click of the related limit 

switch 

• actuate by means of the relevant internal piston the “system intervened” pressure switch (for this 

operation the pressure switch will be disconnected from their coupling). For others pressure 

devices as pressure transmitters see the relevant manual. 

b) Distribution net, please check: 

• The piping are completely assembled, connected and the supports are properly fixed on the 

structures, walls and ceilings; 

• The CO2 nozzles are installed 

c) Protected area, please check: 

• All passages of the piping through walls and ceilings are well sealed; 

• All the openings, non considered in system calculation are sealed or provided with automatic 

closing devices at the system intervention; 

• All the pre-alert devices for the evacuation of the protected area are correctly installed and visible 

REMARKS: - start up of the CO2 system can be effected only if the detection system has 

been inspected and tested as described in the relevant manual. 

- to make the system working it is necessary to authorize the “AUTOMATIC” function 

in the control panel. At the end of all the above described operations, verify that the 

control panel is fully functioning and that it does not signal any fault or alarm condition. 

WARNING: After system installation and start-up procedure remove the safety pins 

from the cylinders and open cut-off valves. 

NOW THE SYSTEM IS READY TO BE “STARTED” 


Page 22 of 29

9.2. NORMAL OPERATIONS 

SANCO 


Once the system here described is working in accordance with all procedures described in the 

previous chapters and is kept in perfect condition always in accordance with the maintenance 

instructions described in the proper chapters of this manual, is in a position of operate in an 

independent way on condition that all required values concerning pressure and flow are respected. 

At the same time, also detection and control system must be on operating condition, as indicated in 

the relevant manual. 

Particular care must be taken as for new structures or storage conditions of the goods in the protected 

hazard do not imply the good working of the same, or modify the characteristics of the protected 

hazard, making the system not suitable. 

9.3. SHUT DOWN PROCEDURE 

WARNING The system should be placed out of service only for repairs. The work to be done must be 

completed in a manner to minimise the time that the system must be out of service. All hazardous 

activities in the effected area shall be terminated until the system is placed back in service. Any 

system impairment shall be co-ordinated with the owner, local authority having jurisdiction and other 

related parties. Place a roving fire patrol in the area covered by the system until the system is back in 

service. 

Prior to turning off any valves or activating any alarms, notify local security guards and/or central alarm 

station (if used) so that a false alarm will not be signalled and result in a local fire department 

response. 

After the precautions indicated above and before any disassembly of the parts of the system, follow 

the instructions listed below: 

• Close cut-off valve; 

• Disconnect the pneumatic line which controls the pneumatic operators that open the cylinders from 

the discharge collector; 

• Disconnect the opening control levers of the valves mounted on the pilot cylinder; 

• Put, in the appropriate drills, the shear pins which are fixed to the valves body by a small wire rope 

inhibiting the function of the valve itself; 

• Put “SYSTEM OUT OF ORDER” warning notices into positions where they can be well noticed; 

REPAIRS: When necessary, owing to intervention or damages occurred, please execute repairs and 

mind to use same material as the original ones and following in this way the initial project. 

Any difference need to be approved in writing, by SANCO or by the local Authority having jurisdiction. 

Repairs must be carried out in accordance with the guidelines of the operations described in the 

previous chapters. 

RESTART: See Section 8.1 of this Manual “START-UP PROCEDURES” for all operations 

concerning the operative restoration of the system. At the end of those operations which have required 

the replacement of some parts, the components which are normally stored as spare parts and which 

have been used for repairs, should be replaced; the new components should be identical to those 

which have been used for repairs or of an equivalent type, authorised by the Manufacturer. 


Page 23 of 29

9.4 TROUBLESHOOTING 

SANCO 


Due to the fact that the CO2 components do not function continuously, they manifest a low degree of 

wear. Therefore, with normal use and preventive maintenance carried out, protecting against corrosion 

and eventual mechanical damage caused by accidental impacts, the system should be reliable for a 

long time.

11. INSTRUCTION FOR THE CYLINDERS RECHARGING 

When, after an intervention discharge or for the restoration of the nominal charge of the extinguishing 

agent, it is necessary to refill the cylinders, proceed as follows. 

WARNING CO2 cylinders should never be handled or moved without the protective safety cap 

securely in place. DO NOT remove this cap until the cylinders have been installed in to their rack. 

11.1. REMOVAL 

• Temporarily put the system out of order, acting on the control and signalling panel, according to the 

procedures described in the relevant manual 

• Verify that all precautions have been taken, in order to act in complete safety condition on the 

cylinders batteries, included the warning by means of a proper notice indicating ‘SYSTEM OUT OF 

ORDER’. 

• Disarm the emergency control systems, where existing and the electromechanical controls of the 

cylinders and on the release cabinet. 

• Draw off the valve lever from the cylinder valve. 

• Disconnect the discharge hose from the cylinder. 

• Disconnect the cylinder from the rack following backwards the indications contained in the chapter 

concerning the installation of the same. 

• Send the cylinder to the supplier for relevant recharging and checking, it will have to be sent 

complete with the relevant protections (cap, seal, etc.) 

11.2. RECHARGING 

• Carry out the weighing of the cylinder for the definition of the quantity necessary for the restoring of 

the discharge conditions. 

• Verify if it is a restoration, the seal of the valve by means of proper liquids or sprays for searching 

of little leakage. In case some leakage could be found out, completely discharge the cylinder, after 

having blocked it firmly and provide for maintenance or replacement of the valve with another of the 

same type. 

• Place the cylinder on a balance, fixing it and verifying its stability. 

• Connect the valve, outlet site, to the hose of the recharging system, provided with the shut-off and 

vent valves. 

• Steadily tighten the connections. 

• Open the cylinder valve, and verify that the shut-off and vent valves are closed. Verify the seals, if 

they works with cylinders partially charged. 

• Open the charging valve and transfer the extinguishing agent in the cylinder. When the desired 

weight is reached, close the charging valves and the cylinder valve. Open the vent valve and verify 

that there are no leakage from the circuit. If it is necessary close again and verify the closing of the 

other valves 

Disconnect the hose from the cylinder and the same one from the balance. Take note of the date of 

the recharging on a proper register, included the possible maintenance carried out. Verify the seal of 

the valve and apply the transport seals and the proper protections

ISSUE G.1

ENCLOSURES 

INTRINSIC SAFETY 

Pressure switches neither store nor 

generate electricity and are therefore 

normally usable in intrinsically safe 

circuits without further certification 

provided that the power source of the 

circuit is certified Exi and the installation 

is in accordance with the relevant 

codes of practice (e.g. ANSI/ISA 12.6 or 

BS 5345 Part 4, 1977). Because of the 

low voltages and currents of I.S. circuits, 

we recommend using gold and/or 

sealed contacts. 

Temperatures in Table 1 refer to 

limitations for certified enclosures. See 

TECHNICAL DATA. 

NOTE: Codes T and U - to increase gas 

class see Table 6. 

NOTE: Codes H, T for 4X 

Aluminium Enclosure protected by 

quality epoxy paint system. 

Performance of enclosure requires 

careful installation and sealing of cable 

gland connection in situ. 

Assembly requires to be built for Marine 

use, See Table 8, Code 02. 

JAPANESE APPROVAL ✽ 

An enclosure Code `B' is available that 

meets the requirements of Japanese 

industrial standards for use in hazardous 

areas. Details on application.

In the interest of development and improvement Delta Controls Ltd, reserve the right to amend, without notice, details contained in this publication. 

No legal liability will be accepted by Delta Controls Ltd for any errors, omissions or amendments.

GENERAL 

The unit is manufactured, checked and supplied in 

accordance with our published specification, and when 

installed and used in normal or prescribed 

applications, with the lid in place and within the 

parameters set for mechanical and electrical 

performance, will not cause danger or hazard to life or 

limb. 

HEALTH AND SAFETY AT WORK ACT 1974 

WARNINGS 

1. THE USERS ATTENTION IS DRAWN TO THE 

FACT THAT, WHEN THE UNIT IS ‘LIVE’ WITH 

RESPECT TO ELECTRICAL OR PRESSURE 

SUPPLIES, A HAZARD MAY EXIST IF THE 

UNIT IS OPENED OR DISMANTLED. 

2. UNITS MUST BE SELECTED AND INSTALLED 

BY SUITABLY TRAINED AND QUALIFIED 

PERSONNEL IN ACCORDANCE WITH 

APPROPRIATE CODES OF PRACTICE SO 

THAT THE POSSIBILITY OF FAILURE 

RESULTING IN INJURY OR DAMAGE CAUSED 

BY MISUSE OR MISAPPLICATION IS 

AVOIDED. 

OPERATING PRINCIPLES 

Process pressure is sensed by a diaphragm that 

generates a force proportional to the applied pressure. 

This force is opposed by an adjustable spring which, at 

the point of equilibrium permits movement of an 

operating rod which actuates a switch or switches. 

Note: Should the diaphragm fail the process will vent 

to atmosphere via a control orifice without pressurising 

the switch enclosure. 

INSTALLATION 

The instruments are designed to be mounted vertically 

with the process connection underneath. However, 

mounting up to 45° from the vertical in any plane is 

acceptable, although a small calibration shift may 

occur. They can be mounted either direct to process, 

or to a wall or panel using the four mounting holes 

provided. Select the mounting point so as to avoid 

excessive shock, vibration or temperature fluctuation. 

Instruments should be mounted to avoid excessive 

heat transfer from the process lines or adjacent plant. 

To avoid undue stresses being imparted to the 

instrument when wall / panel mounted, it is 

recommended that a short length of flexible line be 

installed between the instrument and process line. 

Take care to select and install adaptors to the 

electrical entry that do not reduce the enclosure 

degree of protection. 

NOTE: Enclosure Codes H, T & B for NEMA 4X 

use. 

To ensure performance of enclosure, careful 

installation and sealing of cable gland in situ is 

required. 

On enclosures H, R, T, B and U, remove the lid using 

an appropriate tool if tight eg edge of spanner or metal 

rod (fig 2).

Zone 1 Enclosure (H, R, T, U, B) 

Thread seal and contact surfaces must be lightly 

lubricated using a non-setting non-corrosive grease 

compatible with the lid seal. Do not use copper 

bearing grease. Screw on lid hand tight making sure 

that mating surfaces of the lid and enclosure are in 

contact. Re-tighten the lid lock screw. 

WARNING: IT IS A SAFETY REQUIREMENT THAT 

AT LEAST 5 FULL THREADS ARE ENGAGED WHEN 

THE UNIT IS IN OPERATION. NEVER OPERATE 

THE UNIT UNLESS THIS CONDITION IS MET. DO 

NOT USE GREASES OR LUBRICANTS NOT 

COMPATIBLE WITH THE ENVIRONMENT OR 

PROCESS. 

Weather-proof Enclosure (W) 

If lid gasket is dried out or damaged, replace with new 

greased gasket. Make sure gasket aligns correctly 

with sealing faces. 

Stainless Steel Weather-proof Enclosure (A) 

Check gasket. If damaged, replace. 

OPERATION 

Pressure switches are supplied calibrated against 

falling pressure unless otherwise specified. Set Point 

adjustment refers to falling pressure. Switching 

differential is the difference between the set point and 

the operating value on rising pressure. For opening 

details see Figs 2, 6, 7, 8. 

Set Point Adjustment: Models S21, S22 (Figs 3, 4) 

1. Isolate the instrument from the process and power. 

2. Loosen lid lock screw and remove the lid. 

3. Retain in a safe place to avoid damage to threads. 

4. Slacken the set point lock screw. 

5. Rotate the set point adjuster screw as required. 

Rotate clockwise to increase the set point and counterclockwise 

to decrease the set point. 

6. Tighten the set point lock screw. 

7. Replace the instrument lid (see maintenance). 

Switching Differential Adjustment: Models S22 

(Figs 3, 4, 5) 

1. Isolate the instrument from process and power. 

2. Loosen lid lock screw and remove the lid. 

3. Retain in a safe place to avoid damage to threads. 

4. Rotate the knurled plastic wheel on the microswitch 

to adjust the switching differential. Rotate clockwise to 

increase differential and counter-clockwise to reduce 

differential. 

Note: Rotating the knurled plastic wheel will alter the 

operating value on rising pressure only. 

5. Replace the instrument lid (see maintenance). 

Note: For accurate setting, a suitable pressure gauge 

must be used in conjunction with the above procedure. 

Do not attempt to set the switch outside the scale 

limits. Though the unit may be set anywhere within its 

operation range, for optimum performance, it is good 

practice to have a set point value between 25% and 

75% of span.

Low Voltage Directive (LVD) – 73/23/EC Amended by 93/68/EEC. Switch products with 

enclosure codes ‘W’ and ‘A’ supplied CE-marked must be installed and used in accordance 

with the main instructions and this addendum supplied with each product. Products rated lower 

than 50V ac and 75 V dc are outside the scope of the LVD, and therefore, do not require CEmarking 

under this directive. The LVD does not apply to products with enclosure codes ‘H’, ‘K’, 

‘R’, ‘M’, ‘N’ for use in hazardous areas. Switch products with enclosure codes ‘H’, ‘K’, ‘R’, ‘M’, 

‘N’, are covered by the Explosive Atmospheres Directive ATEX – 94/9/EC and when CEmarked 

will indicate compliance with this directive alone. The following directives do not apply 

to switch products manufactured by Delta Controls: 

Electromagnetic Compatibility EMC – 89/336/EEC amended by 93/68/EEC. 

Machinery Safety Directive MSD – 89/392/EEC amended by 93/68/EEC. 

WIRING 

ENCLOSURE ‘W’ 

Cable Glands and adaptors – If enclosure ‘W’ is supplied with a through hole of 22 mm 

blanked with a blind grommet. Discard the grommet and fit a suitable proprietary brass or 

nylon M20 cable gland with thread length of 10 mm and locknut. Fit the nylon reducer provided 

to the inside and a fibre washer to the outside. See diagram 1. 

Alternately, the enclosure may be supplied from the factory with a threaded adaptor ready to 

accept the customer’s gland or conduit system. 

Alternatives: 

i) a metal or nylon adaptor may be used to accommodate other sizes of gland eg NPT, or 

conduit system. See diagram 2. 

ii) an elbow kit may be supplied to enable the entry to be rotated axially through 90° and 

radially through 360°. See diagram 3. 

Earthing / grounding – The user must make suitable local earthing arrangements, if required, 

to ensure that metal glands are earthed. 

An earthing point is provided inside the enclosure. If this is disturbed in any way it must be 

reassembled correctly to be an effective earth and prevent ingress. See diagram 4. When 

removing the lid slacken the M4 nut first and ensure it is re tightened whenever the lid is 

replaced. See diagram 4.1. 

ENCLOSURE ‘A’ 

Cable Glands and adaptors – Enclosure ‘A’ is supplied with an M20 x 1.5 tapped hole. Use a 

suitable stainless steel cable gland and sealing washer. Alternately the enclosure may be 

supplied with a threaded adaptor fitted at the factory ready to accept the customer’s gland or 

conduit system. See diagram 5. 

Earthing / grounding – Bonding between the enclosure and gland / adaptor will be achieved 

when both parts are screwed together. An earthing point is provided inside the enclosure. If 

this is disturbed in any way it must be reassembled correctly to be an effective earth and 

prevent ingress. See diagram 4. 

EARTHING / GROUNDING OF PROCESS CONNECTION AND BACK PLATES – All the 

internal dead metal work is bonded to the enclosure earthing point. Due to requirements of 

sealing, the process connection and back plates may be isolated from the earthing point. Do 

not, therefore, rely on either for earthing, instead always use the earthing point provided. If 

required, the process connection and back plates may be bonded locally. Never use the 

process connection or inlet pipe for locally grounding welding equipment unless it is separately 

earth bonded. 

Pollution degree – all products are suitable for use in pollution degree 3. For extreme 

conditions where condensation may readily form, then sealed contacts should be used. See 

Table A codes 08/09, 0G/0H, H2/H3/H6. 

Electrical isolation – These products are not suitable for electrical isolation. Always isolate 

circuit separately to carry out any electrical work.

The electrical rating is dependent on the microswitch fitted to 

the instrument. The electrical rating is defined by each 

approval that the microswitch complies with and is shown on 

the product nameplate, ie UL / CSA, or IEC. It should be 

noted that the switch must be used within the electrical rating 

specified from the approval you require. Table A lists the 

actual IEC ratings against the Designation & Utilisation 

Category marked on the nameplate. In the absence of any 

verification by UL / CSA the microswitch *manufacturer’s 

rating is specified in bold italics. If in doubt, seek guidance 

from factory.

- Il dispositivo di pesatura serve ad indicare il peso di agente estinguente nella bombola. Il dispositivo deve 

essere tarato per segnalare un valore pari al 10% della carica totale della bombola. 

- The weighing device is used for indicating the weight of the extinguishing agent in the steel cylinders. The 

weight must be adjusted until a leakage indication is given when a max. of 10% weight-loss of the cylinder 

contenets has occured. 

Taratura / Calibration 

- La tabella riportata indica il peso da applicare in funzione del peso della bombola carica. 

- According to the cylinder weight inclusive of its contents, different counter-weight are used

nut. 

Taratura del dispositivo di pesatura / Adjustment of the weighing device 

1. Avvitare il dado di regolazione fino a quando il peso rimane in posizione di equilibrio orizzontale. 

Screw the adjusting nut into the threaded stud until the weight stays in balance horizontal position. 

2. Girare in senso orario il dado fino ad indicare una perdita di peso del 10%. 

Turn the nut clockwise till a weight loss 10%. 

3. Bloccare il dado e piombare il peso con filo di rame. 

Lock the nut and lead the weight with copper wire.
