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, CO
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 water 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.

OPERATOR’S INSTRUCTIONS
This section covers operating controls, pre-operation check, Unit operation, and maintenance procedures that
may be performed by the Operator.
IMPORTANT: Only qualified Personnel should service internal components of the Unit.
PROPER BEER STORAGE
Beer is a perishable product that can be materially changed by improper handling. Undesirable dispensed beer
can be created by improper cooling of the beer or lack of cleaning/sanitizing the beer systems. Proper temperature control of stored beer is important. It helps retard growth of mold, yeast, and bacteria that are non-toxic but
do affect taste and appearance of the dispensed beer. These organisms can be satisfactorily controlled by
maintaining stored beer within a specified temperature range and regularly sanitizing the beer systems. Stored
beer temperature should be maintained at 33° F to 40° F.
OPERATING CONTROLS
