2 CONTENTS 1. Introduction User Instructions 2.1 Operation of the cooler Cleaning Routine Specification Installation Fitting the accessories Maintenance Exploded View Spare Parts List Fault Finding Wiring diagram INTRODUCTION The Concord is a range of upright beer coolers designed to be sited either remote or under the counter. A recirculation pump provides both constant agitation of the water bath and a flow of recirculating chilled water around the python. The recirculating water keeps the beer in the python cold. The cooler has been designed with simplicity and reliability in mind. Normally the cooler will produce nominally 16kg of ice. A full Product data sheet is available detailing the technical specification and range of cooler models. The Concord range is available with several accessories to enhance the specification of the cooler. The Concords have the part number range G xxx. 1

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 8 hours (dependant 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 to 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 off and electrically unplug the cooler. Always use a qualified Service Engineer to repair the unit there are no user serviceable components. On coolers with summer/winter mode fitted. The required mode can be selected by switch, located behind the small access panel on the side of the pump housing (see diagram below). Winter mode selects cooler to control water bath temperature only cooler forms no ice. Winter mode is selected when the green light is illuminated. This facility is used when the incoming beer temperature is low and very little beer cooling is required. Summer mode cooler forms an ice reserve only this is the normal operating mode. 2.2 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 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 beer. The outside of the cooler can be cleaned using a mild non-foaming aerosol cleaner sprayed onto a dry cloth and wiped over the surface of the cooler. Electrically unplug the unit whilst cleaning.

DIMENSIONS Width 440mm Depth 485mm Height 760mm 790mm with No. 15 pump Weight 85kg (operating) Water bath capacity: 34.5 litres PERFORMANCE Ice bank weight 16kg Electrical: See rating plate located on the cooler (or product data sheet) for the electrical rating of this cooler. 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/turn the filler cap or lid inspection panel (as appropriate) and fill the bath with cool, clean, water until the water flows from the overflow. 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 to prevent water from spilling onto electrical components. Once filled with water do not move the unit. 4. If a recirculation pump is fitted, block the outlet. Select Summer or Winter mode (if fitted see product data sheet for exact specification of cooler) as required. 5. Ensure that all covers and access panels are screwed in place. 6. 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. 7. Electrically isolate the cooler. Connect the beer inlet and outlet lines and python water recirculation lines (if used) check for leaks from each joint before completing the insulation. The python insulation should be carefully finished to 3

5 5. MAINTENANCE ensure that all cold surfaces are fully insulated and to prevent air from entering beneath the insulated surface. Note: The dispense performance is dependant on well constructed and well insulated pythons. 8. Sanitise the unit see User instructions. 9. Electrically switch the unit on. 10. The system is now ready for operation but will not give best results until the ice bank is fully formed and the python temperatures are stabilised. 4.1 FITTING ACCESSORIES/OPTIONS Adding extra product coils To add an extra product coil Remove the small cover(s), located in the lid either side of the pump housing, by releasing the latch and sliding the cover out of its location. Remove the blanking piece and slide the cassette coil into position. Various coil lengths are available, ensure that the required coil is fitted. Refit the cover ensuring that the pegs in the side face of the cover are located in the holes provided in the lid. Refit the latch to hold the product coil in position. Fitting a No 15 pump To fit a No 15 pump Electrically isolate the cooler. Remove the pump cover housing and electrically disconnect the pump. Ensure that all of the water in the python has drained. Remove the pump fixing screws and withdraw the pump take care not to drip water on the electrics. Do not tip the pump up as any water in the housing will run into the pump motor. Fit and electrically connect the No 15 pump into the aperture and fix in place. Fit the taller cover to the electric s panel. Ensure that all screws are replaced. Fitting castors to the cooler Each castor has 4 screw fixing points already provided in the base. Either lift the cooler off the floor, or if completely empty of water, tip the cooler back to gain access to the fixing points one located at each corner of the base plate. Fit the castors using only the screws provided long screws may damage the condenser. Take care when replacing the cooler to the upright position. 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 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, use a soft bristle brush to clean the condenser fins of dirt, dust etc. Take care not to damage the fins during cleaning. 3. Check the condition of the python insulation and that the pump is circulating water. 4. 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 this manual and always ensure that the following are observed- 5. When replacing components always use IMI Cornelius approved spare parts. Failure to do so will invalidate the coolers approvals. 6. Always electrically isolate the cooler before removing covers or carrying out any work. 7. After working on the cooler ensure that the unit is left electrically safe and that all covers and cover fixings are refitted. 8. If replacing a condenser fan motor always fit a new fan blade. 9. If removing a recirculation pump do not invert the assembly as water will run into the motor. Do no knock or jar the assembly as this may damage the bearings. 10. The drier must be replaced each time the refrigeration system is opened. 11. Always replace seals, screws covers etc. after servicing the cooler. 4
