Component Description and Function
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 thru 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.
