Component Description

MFI Series

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 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.
