Operation
Sequence of Operation
15 MINUTE TIME DELAY
The 15 minute delay must be expired before the
gearmotor or compressor will energize.
The delay period starts to time out upon application of
power or movement of the toggle switch from OFF to
ICE.
The delay period starts when:
•
The ice machine enters Automatic Shutoff
•
Power is disconnected and reconnected
•
The toggle switch is moved from OFF to ICE
This time delay period can not be overridden and will
reset to 15 minutes if any of the above conditions occur.
PRIOR TO START-UP
When the toggle switch is placed in the ICE position the
following must occur in the listed order before ice
making will start.
•
The ice chute damper must be in the closed or down
position.
•
The 15 minute delay period must be expired. The
delay period starts upon application of power or
toggle switch movement from OFF to ICE.
•
The water sensing switch must be closed (water
reservoir full of water and water sensing float in the
up position).
INITIAL START-UP
Applying power and/or moving the toggle switch from
OFF to ICE 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 gearmotor.
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 gearmotor,
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 gearmotor.
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 gearmotor energizes. The compressor and
condenser fan motor energize 5 seconds after the
gearmotor.
