COMPONENTS
Mechanical Components
Refrigerant Compressor: Provided to pump refrigerant through the refrigeration system. See
the serial number plate for refrigerant specification and electrical characteristics.
Condenser: All air-cooled and liquid-cooled models are provided with a self-contained refrigerant
condenser to remove heat from the refrigeration system. These condensers are designated in
the model number as (“A”) air-cooled and (“L”) liquid-cooled. Remote air-cooled condensers are
also available for some models. These are designated as (“R”) in the model number. (See the
remote air-cooled section of the manual for information on these models.)
Condenser Fan and Motor: Provided with all air-cooled (“A”) models to draw air through the
condenser.
Liquid Regulator Valve: Provided with all liquid-cooled (“L”) models to regulate the flow of
coolant through the condenser and maintain a specified refrigerant discharge pressure.
Heat Exchanger: Provided to sub-cool the refrigerant, ensuring that the refrigerant is liquid at the
inlet of the expansion valve.
Filter Drier: Provided as insurance that all moisture and impurities are removed from the
refrigeration system.
Thermostatic Expansion Valve: Maintains the proper flow of refrigerant, through the system, as
the load changes during the ice making cycle.
Evaporator: A plated copper evaporator is found in all models. The evaporator provides the five
freezing surfaces for ice cube formation.
Defrost Valve: Directs compressor discharge gas to the evaporator, warming it to release the ice
cubes during the harvest cycle.
Water Tank: Provided as a sump to hold the water required to make one batch of ice cubes.
Water Solenoid Valve: Opens to allow potable water to enter the ice machine and closes when
the water tank is filled to the correct level.
Note: There is a strainer in the water valve inlet, which protects the water valve from
particles in the water supply. If the need for cleaning this strainer is frequent, an external
water filter should be provided.
Water Plate: Functions as a water manifold with a flat surface and to regulate the web thickness
between the cubes. This surface is positioned close to the evaporator and acts to form the sixth
side of the ice cubes. The water plate surface has one spray hole for each cell in the evaporator,
to provide water to the freezing surfaces. The water plate surface also has two drain holes
under each cell, to allow unfrozen water to return to the water tank to be re-circulated. The water
plate swings down during the harvest cycle to allow the ice cubes to fall out of the evaporator.
Note: If at any time during the Fill, Freeze, or Circulate cycle the water plate is manually
opened the controller will switch to the step 3 of the ice making sequence on page 26.
