THEORY OF OPERATION
OPERATING SYSTEMS
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 refrigeration
appliances such as a refrigerator or freezer. The refrigerant used in this unit is R-134a.
There are two very important additions to the refrigeration system in the ice maker:
• Hot Gas Valve - This valve allows high pressure refrigerant gas to bypass the condenser and
flow through the condenser accumulator tube.
• Condenser Accumulator Tube - the hot gas pushes liquid refrigerant in the accumulator tube
into the evaporator, helping to evenly heat the evaporator plate so the ice slab releases quickly
and evenly.
