MACHINES
Ice Making Sequence of Operation
PRIOR TO STARTUP
When the toggle switch is placed in the ICE position
the following must occur in the listed order before ice
making will start.
• The 5 minute delay period must be expired. The
delay period starts upon application of power or a
change in toggle switch position.
• The ice chute damper must be in the closed or
down position.
• The water sensing switch must be closed (water
reservoir full of water and water sensing float in the
up position).
INITIAL STARTUP
A 5 minute delay period must expire. The delay period
starts to time out upon application of power and can
not be overridden. When the five minute delay period
expires, the gear motor energizes. The water in the
reservoir closes the water sensing (float switch) and
the compressor and condenser fan motor energize.
FREEZE CYCLE
The float valve automatically maintains the water level
in the reservoir. The ice damper will open and close to
verify ice production. The ice machine will continue to
make ice until the ice damper is held open (up) as ice
fills the bin.
