Component Location and Function

Reservoir: Contains the water used to make ice.
Water Inlet Valve: Opens to allow water into the
reservoir.
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.
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

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.
