1 REMOTE COOLER AIR COOLED & WATER COOLED Installation & User Instructions (To be left with the user) PLEASE READ CAREFULLY BEFORE INSTALLING THE UNIT Please follow these instructions carefully. Only if the remote unit is properly installed and maintained will trouble free operation and customer satisfaction be achieved. GENERAL DESCRIPTION This is a remotely sited cooler used for cooling drinks such as beer, lager, cider & stout. Incorporating mechanical temperature control this unit is suitable for the utilization of water as the product cooling medium and for the formation of an ice reserve. A recirculation pump provides both constant agitation of the water bath and a flow of recirculating chilled cooling medium for python cooling. The remote cooler is fully automatic, therefore, the electrical supply must not be interrupted (unless access for maintenance is required), otherwise reduced performance and reliability will occur. HANDLING & TRANSPORTATION Keep the remote cooler in an upright position and do not drag over rough floors or down steps. Upon receipt, unpack the unit carefully and visually inspect for any damage which may have been sustained during transit. Record the nature of any damage on the courier s delivery note and, at the same time inform your supplier. Once the unit is in position, do not move when filled with water. INSTALLATION Installation must only be carried out by suitably trained person and must comply with national and local codes for connection to electrical supplies. It is recommended that the installation is protected by an RCCB (Residual Current Circuit Breaker). SAFETY Read this booklet before undertaking installation or maintenance.

2 Siting cont. All models (A/C & W/C) Remote coolers should not be exposed to liquid spillage, spray, steam or humidity at a higher level than 90% rh. Site the cooler within 40 metre s of the point of dispense. Locate the cooler within 2 metre s of an earthed, switched, 13 Amp, 230V 50Hz socket which is accessible for isolation of the equipment. The socket must be installed to comply with current IEE regulations. Site the cooler on a firm level surface, protect from physical damage and do not place items on top of, or underneath the cooler. Clear space must be provided above the unit. Allow 50mm clearance around the unit to aid air circulation and keep the front of the unit clear to allow an unimpeded air supply to enter the cooler. Air vents should never become obstructed or blocked. Access should be possible to the front panel for ease of service. Do not stand on this unit. INSTALLATION General WARNING - The appliance must be earthed. If not already fitted, fit the appropriate electrical plug to the service cord. The fuse rating is stated on the rating plate. With the unit unpacked and in position, remove all coil caps, but do not connect to an electrical supply at this stage. Filling the product water bath. Fill with cool clean water until liquid starts to flow from the overflow. Stop filling and close the filler / inspection hatch on the lid of the cooler. Discharge unit (water cooled models) The discharge cooler should be mounted on an exterior wall, not south facing, and provide access for pipes and electrical cable to the base unit (maximum 50m). If no exterior wall is available then mount inside on a wall in a cool room with plenty of fresh air ventilation. Avoid warm areas (i.e. cupboards or small storerooms). Secure the discharge cooler to the chosen location and fix (follow instruction guidance from the discharge cooler). Using a minimum 1.5mm 2 two core cable, connect the Discharge Cooler to the remote W/C cooler. Connect the two core cable to the quick fit terminal block, this is located at the rear of the W/C cooler (Note: This is a nominal 24V 50Hz supply). Complete the glycol circuit by connecting the pipe work between the remote W/C cooler and the discharge cooler utilizing 15mm Service Valves. WARNING - As the glycol lines will circulate a warm glycol mix it is important for safety reasons that suitable tubing is used. Consult a specialist tubing manufacturer or contact Cornelius. WARNING - PVC tubing, whether braided or not, is not suitable for this application. The tubing ID must be sufficient to ensure a minimum flow rate of 4.5 litres/minute in the glycol circuit. It is recommended that an ID of at least 11.5mm be used. Avoid using elbow joints as these cause pressure drops. The tubing must not be routed next to hot surfaces or sharp edges. Avoid ups and downs in each glycol line as this may create air locks. Do not kink or crush the tubing, ensure minimum bend radii of 100mm and support where necessary. WARNING The lines should never be taped together or insulated. Do not use de-ionised water or add any substance to the water (unless approved by Cornelius). Do not leave hose pipes unattended whilst filling the product water bath as the unit may become flooded. Open the filler / inspection hatch on the lid of the cooler. IMI Cornelius 2

3 Priming the discharge unit coolant circuit (water cooled models) CAUTION As the python is not connected at this stage disconnect the electrical supply connection for the recirculation pump from the socket on the rear panel at the back of the cooler. Mix monopropylene glycol and water to give a solution of Minimum 30% glycol 70% water, Maximum 40% glycol 60% water. Glycol should be mixed in a clean container. CAUTION Always mix the water : glycol before filling the system. WARNING - Do not use ethylene glycol. Ensure sufficient glycol/water mixture is available for filling the coolant bottle and topping up during priming before switching the remote W/C cooler on. You will need to prepare: 4 litres of glycol/water mix to fill the water cooled unit coolant system. In addition the complete system will require topping up with the following quantities to give a Minimum 30:70 to maximum 40:60 glycol/water ratio whilst priming: 2.1 litres for every 10m of 11.5mm ID tubing 4.2 litres for every 20m of 11.5mm ID tubing 6.3 litres for every 30m of 11.5mm ID tubing 8.4 litres for every 40m of 11.5mm ID tubing 10.5 litres for every 50m of 11.5mm ID tubing Fill the coolant reservoir to the maximum level (indicated on the front of the coolant reservoir). CAUTION ensure all service valves are in the open position prior to switching on the remote unit Switch on the mains electrical supply to the remote W/C unit. If the mains electrical supply to the remote cooler is not already switched on, switch it on now. CAUTION - All tubing/pythons must be routed to prevent undue stress, tight bends or kinking. From the product python connect the recirculation lines to the flow and return of the top mounted recirculation pump on the remote cooler. It is recommended that this connection is made utilizing 15mm Service Valves to aid with future service requirements. CAUTION - Ensure the recirculation lines are looped at the point of dispense and plug the electrical supply lead for the recirculation pump into the socket on the rear panel at the back of the cooler. Check all plumbing connections for leaks. As the python recirculation lines prime the level of liquid in the product water bath will drop. Refer to section Filling the product water bath to top up to correct level. Connect product in and python supply to each connection on the product coils of the remote cooler. Utilize 3/8 push fit connectors. Note: All lines to be well insulated to the requirements of the system. OPERATION Once connected to the mains electrical supply allow time for the cooler to build a full icebank (refer to relevant Product Data Sheet for time to full icebank), the cooler is now ready to use. Note: there are no user adjustable controls on this remote unit. As the coolant circuit primes, the level of coolant in the reservoir will drop. Keep filling the reservoir with the prepared 30:70 / 40:60 glycol/water mixture, ensuring the level does not drop below the minimum or exceed the maximum levels indicated on the front of the reservoir CAUTION do not allow the base mounted coolant pump to run dry. Connecting the python & product lines. CAUTION Ensure the electrical supply connection for the recirculation pump is disconnected from the socket on the rear panel at the back of the cooler.
