COMPONENT DESCRIPTION
Control Box: Contains the electrical controls that
operate the machine.
High Pressure Cut Out Switch: A manual reset
switch sensing the high side refrigeration pressure.
It is set to shut the machine off if the discharge
pressure should ever exceed 450 psig.
Compressor: The refrigerant vapor pump.
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 no water.
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
gearbox, driving the auger.
Condenser: Air or water cooled, where the heat
removed in ice making is discharged.
Expansion valve: The refrigerant metering
device.
