THEORY OF OPERATION
(see Figure 2)
A CO2 cylinder delivers carbon dioxide (CO2) gas through adjustable CO2 regulators to the beer kegs. When dispensing valves are opened, CO2 gas pressure exerted upon the beer kegs pushes beer from the kegs, through the Unit cooling coils, and on to the beer faucets resulting in cold beer being dispensed.
When the Unit power cord has been plugged into an electrical outlet and the main power switch on back of the Unit (115 VAC, 60 Hz Units only) has been positioned in the ‘‘ON’’ (up) position, the compressor, condenser fan motor, and agitator motor will start and begin forming an ice bank. When a full ice bank has been formed, the compressor and condenser fan motor will stop but the agitator motor will continue to operate, circulating ice wa- ter bath in the water tank. The water tank ice bank sensing bulb will cycle the compressor and condenser fan motor on and off as required to maintain a full ice bank.
