Section 3 Operation
INITIAL START-UP
Applying power and/or moving the rocker switch from OFF
to ON will start a 15 minute delay period. This delay period
can not be overridden. With the water sensing switch closed
(reservoir full of water) the gear motor will energize at the end
of the 15 minute time delay. The compressor and condenser
fan motor energize 5 seconds after the gear motor.
FREEZE CYCLE
The float valve automatically maintains the water level in
the reservoir. The ice damper will open and close to verify
ice production. The ice machine will continue to make ice
until the ice damper is held open (up) as ice fills the bin.
AUTOMATIC SHUT-OFF
When the ice damper is held open by ice, the gear motor,
compressor and condenser fan de-energize. The fifteen
minute delay period starts to time out. The ice machine will
remain off until the 15 minute delay period expires and the
ice damper closes.
RESTART AFTER AUTOMATIC SHUT-OFF
1. Less than 4 hours have passed since automatic shut-off.
With the water sensing switch closed (reservoir full of water)
the gear motor will energize at the end of the 15 minute time
delay. The compressor and condenser fan motor energize 5
seconds after the gear motor.
2. More than 4 hours have passed since automatic shut-off.
The dump valve energizes to drain the evaporator. After 30
seconds the dump valve de-energizes. When the reservoir
fills with water, the water sensing switch closes and the gear
motor energizes. The compressor and condenser fan motor
energize 5 seconds after the gear motor.
NOTE: Ice machines use an auger to remove ice from the
evaporator. Occasional noises (creaks, groans, squeaks, or
pops) are a normal part of the ice making process.
,
Caution
Excessive noise from the ice auger may indicate a more
serious issue causing the evaporator to freeze. Shut
down the machine immediately and diagnose the issue.
