Operation of the cooler
To maintain the safe operation and reliability of the cooler during normal use, please
observe the following points:-
The cooler is designed to run continuously. During normal use it should only be
switched off when cooling will not be required for a period of more than 24hours. The
cooler should be restarted at least 5hours (dependant on model) before it is to be used.
Do not spill or let liquids drop on the cooler –if liquids do spill onto the unit,
electrically isolate before wiping the spillages up.
Do not place items close to the cooler as this can reduce the air flow and reliability of
the cooler.
Do not place items on top of the cooler as this may cause damage to the agitator/pump
assemblies.
Do not move the unit once full of water.
Don not block the water tank overflow tube –any condensation generated by the
cooler must be allowed to run away.
Note: In the event of malfunction switch off and electrically isolate the cooler.
Always use a qualified Service Engineer to repair the unit –there are no user
serviceable components.
Cleaning Routine
Beer coils can be internally cleaned as part of the regular draught beer system
cleaning as follows:-
1. Purge the beer lines with clean, cool water.
2. Add a chlorinated alkaline solution, diluted with the correct amount of water,
to the system.
3. Allow to stand in the pipes for the time specified by the cleaning solution
manufacturer –usually 30 minutes.
4. Flush the system with clean, cool water to remove all traces of cleaning
solution.
5. Refill the system with beer.
The outside of the cooler can be cleaned using a mild non-foaming aerosol cleaner
sprayed onto a dry soft cloth and wiped over the cooler. Electrically isolate the unit
whilst cleaning.
INSTALLATION
Installation to be carried out by a suitably trained person only. Compliance with local
Bylaws and Codes of Practice must be ensured.

To ensure trouble free operation it is essential that the unit is installed correctly and
sanitised prior to use.
1. The cooler should be sited on a firm level surface, in a well ventilated
position, and at a maximum distance of 2 metres from an electrical supply. To
ensure efficient and reliable operation of the refrigeration system allow75mm
clearance around the unit and that there is an un-impeded flow of air to and
from the condenser grilles. Allow for future access to the lid and service
panels.
2. If not already fitted, fit the appropriate electrical plug to the service cord.
Consult local Electrical legislation for correct method of installation.
WARNING –THIS APPLIANCE MUST BE EARTHED
Do not connect the cooler at this point.
3. Remove the filler cap or lid inspection panel (as appropriate) and fill the bath
with cool, clean water until the water flows from the overflow into the drip
tray. Do not use de-ionised water or add any substance to the water. Do not
leave hose pipes unattended whilst filling the water bath –the overflow will
not remove water quickly enough. Once filled with water do not move the
unit.
4. Ensure that all covers and access panels are screwed in place.
5. Ensure that the cooler is electrically safe. The cooler may now be electrically
switched on to allow it to cool whist the rest of the Installation is completed.
The cooler will displace water through the overflow as it forms its ice.
6. Electrically isolate the cooler. Connect the beer inlet line and check for leaks
before completing the installation.
7. Sanitise the unit –see User Instructions.
8. Electrically switch on the unit.
9. The system is now ready for operation but will not give best results until the
ice bank is fully formed.
MAINTENANCE
Maintenance to be carried out by a suitably trained person only. Compliance with
local Bylaws and Codes of Practice must be ensured.
The cooler requires occasional checking and cleaning as follows:-
1. Check that the water level in the tank is up to the overflow. Remove the
inspection/fill cover and observe the water level.
2. Check that the airflow to the cooler is unimpeded and clean the condenser fins.
To clean the fins –electrically isolate the unit and remove the back panel, use
a soft bristle brush to clean the condenser fins of dirt, dust, etc. Take care not
to damage the fins during cleaning.
At regular intervals to be determined by the user and/or owner of the cooler, check for
electrical safety.
If any maintenance/servicing is required, refer to the fault finding chart, wiring
diagram and exploded drawings contained in the product manual and always ensure
that the following are observed:-
When replacing components always use IMI Cornelius approved spare parts. Failure
to do so will invalidate the coolers warranty.

Always electrically isolate the cooler before removing covers or carrying out any
work.
After working on the cooler ensure that the unit is left electrically safe and that all
covers and cover fixings are refitted.
If replacing a condenser fan motor always fit a new fan blade.
The drier must be replaced each time the refrigeration system is opened.
Always replace seals, screws, covers etc. after servicing the cooler.
