AUTOMATIC SHUTOFF
When the ice damper is held open by ice, the
gearmotor, compressor and condenser fan de-
energize. The five minute delay period starts to time
out. The ice machine will remain off until the 5 minute
delay period expires and the ice damper closes.
RESTART AFTER AUTOMATIC SHUTOFF
The 5 minute delay period must be expired. The delay
period starts when the ice machine enters Automatic
Shutoff and can not be overridden.
1. The ice machine was off for less than 30 minutes.
When the 5 minute delay period expires, the gear
motor, compressor and condenser fan motor energize.
2. The ice machine was off for more than 30
minutes.
The gear motor and dump valve energize to drain the
water from the evaporator and reservoir. After 30
seconds the dump valve de-energizes. When the
reservoir fills with water, the water sensing switch
closes and the compressor and condenser fan motor
energize.
CHANGING TOGGLE SWITCH POSITION IN THE
FREEZE CYCLE
Moving the toggle switch from ICE to OFF will start a 5
minute delay period.
• Moving the toggle switch immediately to the ICE
position - The ice machine waits 5 minutes then
starts.
• Moving the toggle switch to the ICE position after 5
minutes have elapsed - The ice machine
immediately starts.
