QuietQube Remote Air-cooled Model with Remote
Condensing Unit
NOTE: Ice machines use an auger to remove ice from the
evaporator. Occasional noises (creaks, groans, squeaks, or
pops) are a normal part of the ice making process.
Operation
The ice machine will not start until:
A. The rocker switch is moved to ON.
B. The transport tube switch is closed.
C. The water reservoir is full of water.
Placing the toggle switch in the ON position starts
the gear motor and energizes the liquid line solenoid
valve. The refrigerant pressure at the condensing unit
increases and the low pressure switch closes and starts
the refrigeration system. The water level sensor controls
the water inlet valve and water level. The freeze cycle
ends when ice contact opens the transport tube switch.
The liquid line solenoid valve closes and the refrigerant
pressure at the condensing unit drops. The low pressure
switch opens and turns off the refrigeration system. A 60
minute time delay period initiates. The ice machine will
restart when the ice transport tube switch closes and the
60 minute time delay period expires.
