Check Operation - Whirlpool 50 Installation Instructions Manual

Unit wiring diagram
This model operates at 115 volts except for the cutter
grid circuit which operates at 8.5 volts at 1 amp.
The compressor runs at all times except when the bin
thermostat becomes satisfied and opens up. This de-
energizes the system except for the transformer and
cutter grid.
Under normal operating conditions, when the
evaporator reaches the preset temperature (+ 100 to
-30 F, depending on thickness of ice) the evaporator
thermostat opens, terminating operation of the fan
motor and pump motor. The hot gas solenoid and the
water valve solenoid are energized at this time and re-
main so until the evaporator reaches 38 + 2OF.
DANGER:
ELECTRIC SHOCK HAZARD disconnect power
before servicing unit. Maximum fuse size: 15
amps.
