Ice Making Sequence of Operation
NOTE: Flake 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.
UFF0200/UFF0350/UNF0200/UNF0300 OPERATION
The ice machine will not start until:
A. The rocker switch is moved to “ON”.
B. Ice does not contact the bin thermostat bulb.
C. The water reservoir is full of water.
Placing the toggle switch in the ON position starts the gear
motor and refrigeration system. The float valve controls
the water inlet valve and water level. The freeze cycle ends
when ice contacts the bin thermostat. The ice machine will
restart when ice no longer contacts the bin thermostat.
RFF0320 & RNF0320 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. Ice Chute Safety Switch
C. Low Water Level Switch
D. High Pressure Cut-out Switch
E. Low Pressure Cut-Out Switch
Placing the toggle switch in the ON position starts the
gear motor and a 10 minute compressor time delay. The
compressor starts and the float valve controls the water
inlet valve and water level. The freeze cycle ends when ice
contacts the bin thermostat. The ice machine remains off
until ice no longer contacts the bin thermostat.
