AUTOMATIC SHUTOFF
When the ice damper is held open by ice, the gear
motor, compressor and condenser fan de-energize.
The five 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
The 15 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 15 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
15 minute delay period.
• Moving the toggle switch immediately to the ICE
position - The ice machine waits 15 minutes then
starts.
• Moving the toggle switch to the ICE position after
15 minutes have elapsed - The ice machine
immediately starts.
