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 refrig- eration appliances. The refrigerant used in this unit is R134a.

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 flow 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.
