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.
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.
Low Pressure Cut Out Switch: A manual reset
control that shuts off the ice machine when the low
side pressure drops below a preset point, 0-4 psig.

ICE 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.
Drain Tube: When uncapped and lowered, drains
the evaporator.
Condenser: Air or water cooled, where the heat
removed in ice making is discharged.
Ice Storage Bin Assembly: A plastic lined,
insulated cylinder that receives, stores and
dispenses the ice. Fresh ice enters at the top, and
when the bin is full enough the ice will be between
the ice level sensors, and the icemaking will stop.
Ice is dispensed through a chute at the bottom
front when the agitator assembly sweeps the ice
through the chute.
Glass Filler Lever: Pushing in on this lever
causes the ice dispensing cycle to occur.
Portion Control Knob: Turning this knob adjusts
the length of time of dispense. Not standard after
6/97.
