machine has a dedicated breaker and an individual RCD/GFCI for the machine. 

Water & electrical isolation switches MUST be installed within 1meter of the machine and 

accessible to the operator 

Electrical connections must comply with local regulatory guidelines 

All DDC Dolphin machines must be earthed (connected to ground) 

5.1 Safe operation 

• This machine should only be used for the purpose for which it was designed 

• Only maceratable friendly products should be put into the chamber 

• DO NOT place plastic or metal objects in the chamber 

• Always follow instructions detailed in the user manual 

WARNING 

If there is no active water connection, Turn OFF the electrical supply to prevent premature 

wear of the water inlet valve 

FLOOD WARNING 

This machine must be connected to a functional drain. The overflow connection is 

essential to prevent flooding in the event of incorrect operation 


6. Installation process 

6.1 Plan the installation 

Confirm with the client an exact location for machine prior to any works; explain the installation 

process and what is involved. Discuss and agree a safe working practice for the installation of the 

machine and the transportation of the machine if it is not in the desired location. 

Services 

Review the drainage requirements of the machine and inspect the services available, ensure they 

are suitable for product to be installed. Machine requirements are detailed in this manual. Ensure 

that the electrical and water isolators are easily accessible when the machine is fitted. 

The macerator should always be connected at the lowest section of the soil pipe in a room. All 

other devices such as a sink, hopper or bedpan washer should be placed uphill (on the soil pipe) 

from the macerator. This best practice will ensure any device emptying water and fluids into the 

soil pipe is flushing past the macerator and helping to wash the slurry through the pipe network. 

Location for the machine 

Determine how the client would like the machine to be fixed to the floor. This device must be fixed 

in place using expanding floor bolts (not supplied) or flexible adhesive (not supplied), If floor bolts 

are used ensure the area does not have under-floor heating, cables, pipes, etc. 

Ensure the floor covering if free from damage and in good order. 

Ensure the floor surface is flat and even, the macerator must be level. If the machine is not level 

this will cause uneven wear and strain on the motor, seals and cutting mechanism, in time this will 

impact the performance of the machine. 

Access to the machine 

Ensure the position of the machine allows users easy access to operate the footswitch, load the 

chamber and operate the start switch. Ensure there is sufficient room to work on the machine when 

conducting maintenance tasks. 

Clearance for the lid 

Ensure there are no wall mounted objects, cupboards, drying racks etc. which may impede the lid 

from fully opening.

6.2 Manual handling 

Use safe working procedures when moving or handling the machine. Use appropriate appliances 

to lift and move the machine. Handle the machine with care, avoid scuffs, scratches and damage 

during the installation process. Wherever possible keep the machine inside the packaging to 

protect the surfaces. 

6.3 Unpacking the machine 

Inspect the packaging of the machine check that it is free from damage, remove the packaging and 

check the machine is free from damage. These checks should be done when the machine is 

delivered to site. Retain the plastic machine cover; this can be used to protect the machine from 

dust and debris, if required. Dispose of any unwanted packaging in a safe manner and in 

agreement with the site/client. 

Un-bolt machine from pallet 

• Remove the outer packaging from the machine along with the clear plastic bag 

• Remove the front panel of the machine by removing the fasteners identified 

• Gently pull the front panel forward and down to remove 

• Store front panel & fixings in a safe place 

• Remove the foot switch plate (two nuts at rear of plate), see 6.4 

• Remove the two securing bolts, holding the machine to the pallet, with a 13mm wrench 

• Re-fit the foot switch plate & tighten the nuts 

• Re-fit the PCB housing and tighten the bolts 

• Lift the machine clear of the pallet 

Remove the two bolts, gently pull the front 

cover forward and down. 


6.4 Removal and fitting of foot cup assembly 

The foot cup assembly can be removed to gain better access to components on the base panel of 

the machine. 

Removal 

• Turn off the electrical supply to the machine and remove the front panel. 

• Locate and remove the two hex head bolts which secure the foot cup assembly in place 

and keep the bolts in a safe place. 

Hex head bolt located left hand side of 

machine 

Hex head bolt located right hand side of 

machine 

Lift front plinth assembly up to remove. Be 

careful not to stretch the foot cup wiring 

loom 

Note that the wiring loom to the foot sensor PCB will be still attached at this point and is 

on a short wire loom 


• Unclip the wiring loom from the foot sensor PCB noting which way round it was fitted. 

Refitting 

• Fit the wiring loom connector to the the foot sensor PCB. The connector should be orintated 

so the yellow cable is at the top, black in the middle and red at the bottom. 

• Replace the footcup plinth assembly and refit the two hex head bolts with washer and split 

ring 


6.5 Remove materials from chamber 

• Connect the machine to an electrical outlet (this can be a temporary supply for this task) 

• Allow the machine time to power up (45 seconds) 

• Place foot into foot cup to activate lid operation 

• Allow the lid to fully open 

• Unpack items stored in the chamber 

• Very gently push the lid down, auto close will take over 

• Allow lid to close and lock then turn OFF the electrical supply 

6.6 Remove the protective film 

The stainless steel sections of the machine have a protective layer of plastic film. This must peeled 

away from the machine. Take care to remove all of the film leaving no torn edges. Use a safe 

sharp knife to remove any flakes or remnants of plastic. 

6.7 Check internal parts 

Check the electrical supply is turned OFF. Remove front panel and visually inspect the internal 

parts of the machine for any damaged or loose parts. Check all bolts and fixings for the internal 

parts and components. 

6.8 Cold water connection 

Water hose connection 

This machine is supplied with a 1.5m flexible water hose fitted with a female ¾ “B.S.P. threaded 

fitting”, a suitable cold water supply outlet is required. The hose connection tap MUST be within 1 

meter of the machine & easily accessible to the operator of the machine. 


Water pressure & flow rate 

DDC Dolphin Ltd macerators are fitted with an integral water tank, using an air gap between the 

inlet valve and the top of the tank; this ensures the water used in the machine is isolated from the 

client’s incoming water supply. Water is extracted from the tank and replenished throughout the 

cutting cycle. The incoming water pressure and flow rate must be sufficient to re-fill the tank, poor 

water pressure or low flow rate may cause the pump to run dry, damage to the pump and provide 

poor cutting or flushing within the machine. 

Water pressure 1 bar (minimum) 6 bar (Maximum) 

Water flow rate 

12Litres @ 1 bar (minimum) 

If there is strong water pressure the water supply to the machine should be controlled by restricting 

the flow of water. The water inlet solenoid inside the machine should open only once or twice 

throughout the cycle and close 5-10 seconds after the cycle is complete. Adjustments to the water 

isolator and or flow restrictors can be used to control the rate at which the water tank refills. 

Restricting the flow of water will eliminate “water hammer” when the inlet valve opens and closes 

repeatedly. 

DDC Dolphin Ltd. macerators are fitted with a flexible hose for the water inlet, this ensures any 

vibration from the machine will transfer and weaken the incoming water supply. These machines 

are not designed to have a rigid copper or plastic pipe water supply. 


Double check valve/non return valve 

DDC Dolphin Ltd. recommends the installation of a double check valve (non-return valve) fitted 

prior to the hose connection. This device will ensure the client’s incoming water supply is protected 

from the flexible hose.

Isolation tap for the water supply 

This machine MUST be fitted with a facility to turn off the water supply to the machine; this must be 

within easy reach of the machine. This facility must be fitted before the hose connection or form 

part of the hose connection. This isolation tap (gate valve) is used when working on the machine 

and may be required by the users in the event of leak or problem with the machine. 


6.9 Waste outlet connection 

The configuration of the waste outlet is essential for the correct operation of all macerating 

machines. The macerated slurry must have a clear and unobstructed path through the soil pipe to 

the main public sewer. 

The machine is supplied with a “P trap” complete with 50mm compression fitting. The waste pipe 

from the machine must take the most direct route to the soil stack or drain. Do not use 90 degree 

elbows or tight bends. Use swept bends only. . 

Rubber coupler 

Canplas “P trap” 

Ensure that adequate Rodding access points are provided and that the pipework is fully supported 

throughout with an ideal fall of 1:40. (Minimum acceptable fall is 1:25) 

The 2” (50mm) pipe work from the machine should be kept as short as possible, and no longer 

than 1 meter. The 2” (50mm) pipe should be connected to the 4” (110mm) soil pipe using a “swept 

T” with 4” (110mm) to 2” (50mm) “off-set reducer”. If connecting to an open end of the 4” (110mm) 

soil pipe use the “off set reducer”. 

IMPORTANT 

This machine must never be connected to a drain network containing pipework smaller 

than 2” (50mm). 

Connection to a 4” (110mm) waste pipe must be within 1m of the machine 


Height of waste and soil pipe 

The centre of the 4” (110mm) soil pipe must not be higher than the centre of the “P trap” outlet 

from the machine. Ideally the 4” (110mm) soil pipe should be slightly lower giving adequate 

downhill run for the macerated pulp. If required the large silicone tube connected to the “P trap” 

inside the machine can be adjusted by releasing the hose clamp at the top of the tube. The silicone 

pipe can slide up and down the waste outlet spigot from the lower chamber. 

Additional adjustment can be made at the bottom of the silicone tube. The tube can be cut short to 

lower the waste leaving the machine. This should only be done if absolutely necessary. 

Release hose clamp and move 

silicone tube on machine outlet to set 

the angle of waste leaving the 

machine 

Lower section of pipe can be cut 

shorter to adjust angle of waste 

output. Please note this will lower 

the waste height leaving the 

machine 

Only cut the silicone tube as a last 

resort. If the tube is cut it must be 

cut neatly and square. If cut at an 

angle the machine will leak 

Waste pipe leaving the machine must not run uphill. If soil pipe connection is too high, 

please use optional plinth 


Do not use 90` bends for the waste output of 

the machine 

Only use swept bends to aid the flushing of macerated waste 

Important features of the drain requirements 

The macerated slurry leaving the machine must have an unhindered downhill journey to the main 

sewer. If the waste & soil pipes do not have the correct fall and/or have tight 90 degree bends the 

slurry may not flow freely, congregate potentially causing a blockage. 

The macerator should always be connected at the lowest section of the soil pipe in a room. All 

other devices such as a sink, hopper or bedpan washer should be placed uphill from the 

macerator. This will ensure any device emptying water and fluids into the soil pipe is flushing past 

the macerator and helping to wash the slurry through the pipe network. 

Macerator installed 

at lowest point of 

soil pipe run 

Sinks & hoppers

Soil pipe hidden in wall 


Rodding points 

Rodding points should be installed at critical points along the length of the soil pipe. These features 

are strongly recommended as users of the machine may, in error, place latex gloves or other 

materials into the machine, non maceratable items present a risk of drain blockage. 

Air admittance valves 

Air admittance valves should be installed at appropriate locations to help overcome negative 

pressure build up in the drain network. These units will allow the macerated slurry to flow inhibited 

by negative pressure or vacuum within the pipe network. Refer to plumbing/building regulations for 

further guidance. 

Existing services 

The client may not fully understand the construction of their soil network or they may have no 

alternative but to use the existing services. All possible check should be made to ensure these are 

in good order, free from blockages and leak free. In addition to the clients soil pipes it is essential 

that all underground drains leading to the main sewer pipe are in good condition. Defects, 

obstructions, pinched or crushed drains may cause a blockage when using a heavy loaded 

macerator. 

6.10 Overflow connection 

The water tank fitted the DDC Dolphin Ltd. macerator has an overflow output which can be taken 

from the left or right hand side of the tank. The default connection is on the right side of the 

machine. The overflow can be swapped to the right if required. 7/8” (21.5mm) pipe should be used 

from the compression fitting on the tank down to the tun dish or soil pipe fitting. The overflow 

connection must meet local regulatory standards. 


If connecting to the soil pipe this can be done via a strap on boss or a reducer fitted to the 4” 

(110mm) pipe. Alternatively a 2” (50mm) swept T can be used to form the waste output of the 

machine, a 2” (50mm) to 7/8” (21.5mm) reducer should be fitted to accept the overflow pipe. 

Overflow non return system 

The overflow pipe must have a non-return system to prevent the back flow of gas from the soil pipe. 

Local regulations will dictate which type is used; common methods are “tun dish” and “non-return 

valves”. If using a non-return valve, ensure the device is fitted at least 300mm below the top of the 

water tank.

6.13 Assemble the chemical system 

If ordered with the machine, a disinfectant system will be included with this machine, comprising of: 

• Bottle of fluid 

• Wire rack holder with base plate 

• Metal straw 

• Delivery tube 

Unroll the narrow tube attached to the chemical pump and feed the open end through the rear of 

the machine. Mount the wire basket in a suitable location ensuring staff are able to reach the unit 

when the chemical bottle needs to be replaced. Ensure the cage is fitted with a flat base plate. 

Check that the cage/cabinet is clear of the machine lid when it opens. 

Check the location of the cage/cabinet is within reach of the chemical tube. Fit the open end of the 

chemical tube over the bottle top probe, there are two options available: 

• The chemical tube can be fitted directly to the metal straw, warming the open end of the 

tube and applying a silicone lubricant to the metal straw will aid this process 

• Use long nose pliers to stretch and open the tube, apply silicone lubricant to the probe 

DO NOT use pliers or grips to force the tube over the metal straw 

Remove the standard bottle top and secure the metal straw bottle top to the chemical bottle. 

Support the chemical tube above the bottle using a “P” clip or other suitable fixing. Any surplus 

chemical tube should be coiled into the base of the machine. The supply tube can be cut to length 

once the chemical bottle is in place. DO NOT cut too short, the machine may move for service 

work, slack will be required to remove the probe to change the chemical bottle.

The chemical bottle must sit on a solid surface: ensure wire rack is fitted with a base plate 


6.14 Boxing in 

Where it has not been possible to fit the machine up tight against the rear wall, DDC Dolphin Ltd 

recommends that the gap between the rear of the machine and the wall is boxed in. This will 

prevent items from falling down behind the machine in areas that may be difficult to reach. 

6.15 Clean all outside surfaces 

Clean all external surfaces of the machine, using a soft damp cloth (WD40 can be used to clean 

and polish the stainless steel sections of the machine. 

6.16 Clear working area 

Ensure all packaging and installation debris have been removed from the area and put into the 

appropriate refuse container. 

6.17 Clean any scuff or marks on the floors or walls 

Check the installation area for any scuffs or marks that may have been caused during the 

installation process. 

6.18 Fix the wall posters 

Each DDC machine is supplied with a number of instructional wall posters these must be fitted to 

the wall in close proximity to the machine. 

6.19 Cover and protect machine until ready to use 

Cover and protect the machine if installed in a construction area, use the original packaging to 

protect the machine surfaces from abrasive dust and debris. 


7. Request DDC Dolphin Ltd agent to commission the machine 

This machine must not be used or operated until it has been fully commissioned by a trained and 

approved DDC agent. The machine must have both electrical and water service isolated. 

Operation of the machine before this visit will invalidate the warranty. 

Safety and vital operational sensors within the machine must be calibrated and tested. This forms 

part of the commissioning routine. 

Never leave the machine with the electrical power switched on without a live water connection and 

being connected to a working drainage system 

IMPORTANT 

Never leave the machine with the electrical power switched on without a live water 

connection and being connected to a working drainage system

8. Scale management 

Scale management is recommended on DDC Dolphin Ltd macerators in exceptionally hard water 

areas where scale is known to cause issues cold water system. Approximately 70% of the water 

used throughout the world is naturally hard, meaning it contains a high mineral content, including 

calcium as well as various other salts. Calcium deposit build up can have detrimental effect on 

pipes, valves, spray heads and other devices within the machine. Please note components 

which fail as a result of scale deposits are not covered under warranty.

It is important to check the water hardness prior to installation of the machine. Chemical treatment 

of the incoming water supply helps to manage and control the build-up of scale. DDC Dolphin Ltd 

offers a suitable and safe solution to use with our range of macerators. 

DDC can offer assistance and advice to help identify the water hardness in your country/region. 


8.1 DDC Dolphin Scalematic Cartridge 

This self-contained system uses a disposable canister containing food grade softening agents. The 

cartridge is plumbed into the cold water supply of the machine. Small amounts of chemical are 

released to soften the water reduce the level of scale build up. This automated system delivers a 

fixed level of agent ensuring the cartridge will last for 6 months.
