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.

Self-Contained Air-Cooled
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. Low Evaporator Temperature Thermostat
C. Low Water Level Switch
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.
