●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 exceeds 450 psig.
●Low Pressure Cut Out Switch: An auto-reset switch sensing the low side refrigeration pressure. It will
disconnect power to the circuit board and shut down the machine if the low pressure falls too low.
●Evaporator: A vertical stainless steel tube, refrigerated and water filled. Utilizes a stainless steel auger.
●Compressor: The refrigerant vapor pump.
●Water Reservoir: Float operated, it maintains the water level in the evaporator at a constant level, and 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 ice machine
off if there is no water in the reservoir.
●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 discharge chute.
●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.
