Section 3
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.
Evaporator Low Temperature Safety
Thermostat and Bin Thermostat
The bin thermostat sensing bulb is located in the ice
chute or bin and turns the ice machine on and off as the
level of ice in the ice chute or bin changes.
RF0244/RF0266/RF0385/
RF0388/RF0399/RF0644 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.
