COMPONENT DESCRIPTION
Control Box: Contains the electrical controls that
operate the machine.
High Pressure Cut Out: An automatic reset
switch sensing the high side refrigeration pressure.
It is set to shut the machine off at 450 PSIG.
Pump Down Control: An automatic reset
pressure switch connected to the low side of the
refrigeration system. Controls the compressor.
Evaporator: A vertical stainless steel tube,
refrigerated, and water filled. In it, there is a
stainless steel auger.
Reservoir: Float operated, it maintains the water
