VERSION 2 ICE MACHINES R404A OR R290
REFRIGERANT
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 compressor rocker switch is moved to
“ON”.
B. Ice does not contact the bin thermostat bulb.
C. The water reservoir is full of water.
With power supplied and the compressor rocker
switch in the ON position, the gear motor and
refrigeration system start. The float valve controls the
water inlet valve and water level. The freeze cycle
ends when ice contacts the bin thermostat. A
20 minute delay period initiates. The ice machine will
restart when ice no longer contacts the bin thermostat
and the 20 minute delay period expires.
