Component Location and Function
Reservoir:
Contains the water used to make ice.
Water Inlet Valve
: Opens to allow water into the
reservoir.
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 Deflector:
The slots in the inclined deflector
allows the water falling from the evaporators back
into the reservoir, but when ice falls during harvest,
the ice slides off into the bin.
Harvest Bypass Valve
: Injects additional
refrigerant into the harvest system.
Water Pump:
Forces the water from the reservoir
to the top of the evaporator(s). The motor is kept
separate from the water to minimize contact with
moisture.
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 first part of
harvest, when the water pump restarts the water in
the reservoir is diverted to the drain.
Check Valves:
Liquid and Discharge lines contain
check valves. These control refrigerant migration
during the Harvest and Off cycles.
