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.

Operation

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 SHUTOFF

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 SHUTOFF

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
shutoff.
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.
