Comp Label Description Function Basic Operating Logic
Input/
Output
Mix Hopper 20 qt. capacity, wrapped with 40' of 5/
16” copper tubing
Storage of product mix,
evaporator.
Freezing
Cylinder
Conventional, 3.4 qt. flooded
evaporator
Freezing of product,
evaporator.
Condenser Lanced fin Cooling of compressed
refrigerant.
Fan -
Condenser
Motor A.-Fan (Blower) Provides air flow to remove
heat from condenser heat
exchanger.
On with the compressor in
Auto and Standby.
Operates for 30 sec. after
the compressor shuts off.
Output
Compressor Hermetically sealed - Copeland,
CS20
Compresses the refrigerant.
Used for barrel and hopper
cooling in Auto, Standby, and
the cooling phase of the heat
mode.
Enabled in Auto and
Standby. Off in Wash and
Off modes.
Output
AXV Automatic expansion valve for the
freezing cylinder - 046365
Controls the refrigerant flow
during the cooling of the
freezing cylinder.
Filter/Dryer Dryer-Filter-HP62-3/8 x 1/4S -
048901
This keeps moisture, dirt,
metal, and chips from entering
the refrigerant flow control
valves.
Heat Exchanger
(sub cooler)
15.25 joined length This allows the liquid
refrigerant to be cooled before
it reaches the AXV.
When the liquid is
subcooled before it
reaches the refrigerant
control, the refrigeration
effect per unit mass of
refrigerant is increased.
Receiver Accumulator - 047062 The liquid receiver is a storage
tank for liquid refrigerant.
The use of a liquid receiver
makes the quantity of
refrigerant in a system less
critical.
