QUIETQUBE REMOTE AIR-COOLED MODELS WITH
REMOTE CONDENSING UNIT
Normal Operation
When the toggle switch is placed in the ON position the
following controls must be in the closed position before
the ice machine will start:
A. Bin Thermostat
B. High Pressure Cut-out Switch
C. Ice Chute Safety Switch
D. Low Pressure Switch
E. Low Water Level Switch
Placing the toggle switch in the ON position starts the gear
motor. After 8 minutes of correct rotation the time delay
ends and the liquid line solenoid valve opens.
The refrigerant pressure will increase and close the fan
cycling pressure control and the condenser fan motor
starts.
The ice machine will continue to make ice until ice contacts
the bin thermostat and the liquid line solenoid valve closes
and the refrigeration system pumps down.
When the refrigerant pressure is low enough to open the
low pressure control, the contactor coil is de-energized and
the compressor stops.
NOTE: The ice machine remains off until ice no longer
contacts the bin thermostat.
