There are three operating systems in the ice
maker:
• Refrigeration System
• Water System
• Electrical System
REFRIGERATION SYSTEM
The refrigeration system in the ice maker is
very similar to the system used in other refrig-
eration appliances. The refrigerant used in this
unit is R134a.

THEORY OF OPERATION

OPERATING SYSTEMS

There are two very important additions to the
refrigeration system in the ice maker: the Hot
Gas Valve, and the Condenser Accumulator
Tube. The components operate as follows:
• Hot Gas Valve - Allows high pressure
refrigerant gas to bypass the condenser
and fl ow through the condenser accu-
mulator tube.
• Condenser Accumulator Tube - Hot gas
pushes liquid refrigerant through the
accumulator tube into the evaporator,
helping to evenly heat the evapora-
tor plate so that the ice slab releases
quickly and evenly.
