COMPONENT DESCRIPTION
Control Box: Contains the electrical controls that
operate the machine.
High Pressure Cut Out (control): An automatic
reset switch sensing the high side refrigeration
pressure. It is set to shut the machine off at 450
psig.
Pump Down Control: A switch to control the
compressor, depending upon low side pressure:
closes at 30 PSIG, and opens at 15 PSIG.
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
level in the evaporator at a constant level, it also
contains the water level sensor.
Water Level Sensor: Senses if there is water in
the reservoir to make ice out of. Will shut the
machine off it there is none.
Ice Discharge Chute: Directs the ice produced by
the evaporator into the storage bin.

Ice Level Sensor: An electronic "eye", it senses
the presence of ice in the bottom of the ice
discharge chute. Operates to turn the ice machine
on and off automatically as the level of ice in the
bin changes.
Gear Motor: An oil filled, speed reduction
