COMPONENT DESCRIPTION
Control Box: Contains the electrical controls that
operate the machine.
High Pressure Cut Out Switch: An auto-reset
switch sensing the high side refrigeration pressure.
It will shut the machine off if the discharge
pressure should ever exceed 450 psig.
Low Pressure Cut Out Switch: An auto-reset
switch sending the low side of the refrigeration
system. It will disconnect power to the circuit board
and shut down the machine if the low side
pressure falls too low.
Evaporator: A vertical stainless steel tube,
refrigerated and water filled. In it there is a
stainless steel auger.
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
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 gearbox,
driving the auger.
Drain Tube: When
uncapped and lowered,
drains the evaporator.
Condenser: Air or water
cooled, where the heat
removed in ice making is
discharged.
Expansion valve: The
refrigerant metering
device.
