Automatic Shut-Off
7. Automatic Shut-Off
Ice Machine Section: When the storage bin is full at
the end of a Harvest sequence, the sheet of ice cubes
fails to clear the water curtain and will hold it open.
After the water curtain is held open for 7 seconds, the
ice machine shuts off. The ice machine remains off for
3 minutes before it can automatically restart.

Condensing Unit: The liquid line solenoid valve
closes, allowing the refrigeration system to pump
down. When the refrigerant pressure is low enough to
open the fan cycling pressure control,* the condenser
fan motor stops. When the refrigerant pressure is low
enough to open the low-pressure control, the contactor
coil is de-energized and the compressor stops.
The ice machine remains off until enough ice has been
removed from the storage bin to allow the ice to fall
clear of the water curtain. As the water curtain swings
back to the operating position, the bin switch recloses
and the ice machine restarts (steps 1-2), provided the
3-minute delay period is complete.
*The Q0600C ice machine does not use a fan cycle control;
therefore the condenser fan motor will energize and de-
energize with the compressor.
