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 the rotation speed sensor verifies
10 minutes of correct rotation the time delay ends and
the liquid line solenoid valve opens.
• When the refrigerant pressure is high enough to
close the low-pressure control the contactor coil
energizes and the compressor starts.
• 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.
• The refrigerant pressure drops and the fan cycling
pressure control opens stopping the condenser fan
motor.
• 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.
