COMPONENT DESCRIPTION
Control Box: Contains the electrical controls
that operate the machine.
High Pressure Cut Out (control): A manual
reset switch sensing the high side refrigeration
pressure. It is set to shut the machine off at
450 psig.
Reset Switch: Manual reset. Glows when the
unit shuts off from ice discharge chute being
overfilled (opening the microswitch at the top
of the chute), or if either of the pressure cut
out switches opens.
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
gearbox, driving the auger.
Cleaning Drain Tube: When uncapped and
lowered, drains the evaporator.
Compressor: The refrigerant vapor pump.
Expansion valve: The refrigerant metering
device.
