THEORY OF OPERATION (see Figure 2)
A CO
2
cylinder delivers carbon dioxide gas (CO
2
)
through regulated CO
2
regulators to product tanks.
When dispensing lever is opened, CO
2
pressure ex-
erted upon product tanks pushes product from tanks,
through unit cooling coils, to dispensing valves result-
ing in cold dispensed drinks.
When unit power cord has been plugged into electri-
cal outlet and power switch on back of unit has been
flipped to ‘‘ON’’ (up) position, compressor, condenser
fan motor, and agitator motor will start and begin
forming an ice bank. When full ice bank has been
formed, compressor and condenser fan motor will
stop but agitator motor will continue to operate circu-
lating ice water bath in evaporator tank. Evaporator
tank ice bank sensing bulb will cycle compressor and
condenser fan motor on and off as required to main-
tain full ice bank.
