COMPONENT DESCRIPTION
Control Box:
Contains the electrical controls that
operate the machine.
High Pressure Cut Out Switch
: An automatic 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.
Low Pressure Cut Out Switch:
An automatic reset
control that shuts off the ice machine when the low
side pressure drops below a preset point, 15 PSIG.
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.
