C10/C20 Manual
1. INTRODUCTION
The C10 and C20 are a family of over-counter beer coolers designed to be sited on the counter. An
agitator provides constant agitation of the water bath.
These units are available for 230v 50/60Hz or 115v 60Hz supply voltages.
The cooler has been designed with simplicity and reliability in mind.
The C10 cooler will produce a nominal 7kg of ice.
The C20 cooler will produce a nominal 11kg of ice.
A full Product data sheet is available detailing the technical specification and range of cooler models.
2. USER INSTRUCTIONS
2.1 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 longer than 24 hours. The cooler should be re-started at least
5 hours (dependent on model) before it is to be used.
Do not spill or let liquids drip on the cooler – if liquids do spill onto the unit, electrically isolate before
wiping the spillages up.
Do not place items close the the cooler as this can reduce the air flow to 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.
Do 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 of f and electrically unplug the cooler . Always use a qualified
Service Engineer to repair the unit – there are no user serviceable components.
2.2 CLEANING ROUTINE
Product coils can be internally cleaned as follows:-
1. Purge the product lines with clean, cool water.
2. Add a chlorinated alkaline cleaning 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 the cleaning solution.
5. Refill the system with the product.
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 surface of the cooler. Electrically unplug the unit whilst cleaning.

4. INSTALLATION
Installation to be carried out by a suitably trained person only. Compliance with local Bylaws and
Codes of Practise 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 meters from an electrical supply. To ensure efficient and reliable operation of the
refrigeration system allow 75mm 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 lid and filler cap (as appropriate) and fill the bath with cool, clean, water until the
water flows from the overflow into drip tray. Do not use de-ionised w ater or ad d any substance
to the water . Do not leav e hose pipes unattended whilst filling the w ater 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 whilst 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 the unit on.
9. The system is now ready for operation but will not give best results until the ice bank is fully formed.

5. MAINTENANCE
Maintenance to be carried out by a suitably trained person only. Compliance with local Bylaws and
Codes of Practise 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 o verflo w . Remo ve the inspection/f ill cov er 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, 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 o wner 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 this manual and always ensure that the following are observedWhen 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.
