ICE LEVEL SENSORS

MDT5N25 & MDT5N40

COMPONENT DESCRIPTION

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.

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 ice making will stop. Ice is dispensed through a chute at the bottom front when the bin vane sweeps the ice over the chute.
