COMPONENT DESCRIPTION
Water Inlet Solenoid Valve
The water inlet solenoid valve fills the sump
assembly with water. Extra water overflows out the
overflow standpipe of the sump. This action fills
and rinses the sump during each harvest cycle.
The flow rate is 1 g.p.m.
Water Distribution System
The water distribution system functions to evenly
supply water to all cells of the evaporator plates.
The water pump pumps water from the sump up
the vertical tygon tube to the tee. From there water
is channeled through the water manifold to the
water distributors, above each evaporator plate,
and from six holes within each distributor, water
flows to the cells of each side of the evaporator
plates. Gravity flow returns the unfrozen excess
portion of water to the sump reservoir for
recirculation.
Hot Gas Solenoid Valve
The hot gas solenoid valve opens only during the
harvest cycle, to divert the hot discharge gas from
the compressor, by passing the condenser and
capillary tube, for direct flow to the evaporator
plates to release ice cubes from the ice cube
molds.
Fan Pressure Control - Air-Cooled Models only.
ln both freeze and harvest cycles, the fan pressure
control functions to maintain a minimum discharge
pressure by cycling the fan on and off. The
approximate C.I. is 210 PSIG and C.O. is 193
PSIG.
Strainer
A water strainer is located in the potable inlet water
line before the water inlet solenoid valve. Clean
the water strainer frequently.
