Component Description and
Function
Harvest Bypass Valve: Injects additional refrigerant into
the harvest system.
Check Valves: Liquid and Discharge lines contain check
valves. These control refrigerant migration during the
Harvest and Off cycles.
Reservoir: Contains the water for ice making.
Water Inlet Valve: Opens to allow water into the
reservoir.
Water Level Sensor: Controls the size of the ice cube by
measuring how much water is used in a cycle. It consists
of a float, stem and electric eye. The stem will move
slightly when the pump is on, this is normal. As the
machine makes ice the reservoir water level will fall and
the visible portion of the stem will slide down through
the slot in the sensor body.
Evaporators/Freezing Compartment: Location of the
evaporators. Ice forms on the evaporators and is released

when warmed up during the harvest cycle. The freezing
compartment is fully insulated for maximum efficiency.
Cube Deflectors: The slots in the inclined deflectors let the
water falling from the evaporators back into the reservoir, but
when ice falls during harvest, the ice slides off into the bin.
Refrigeration Service Access Valves: Only to be used by a
certified technician. Allows access to the refrigeration system
for diagnostic information.
Water Pump: Forces the water from the reservoir to the top of
the evaporators. The motor is separated from the reservoir water
to minimize contact with the water.
Hot Gas Valve: Closed during freeze, it opens during harvest to
divert hot discharge refrigerant gas into the inlet of the
evaporators.
Purge Valve: Opens during the early part of the harvest cycle to
drain the reservoir.
Ice Sensor: A photo-electric eye set, located at the front and
back of the cube port.
