Ice Making Sequence of Operation
PRIOR TO START-UP
When the toggle switch is placed in the “ice” position
the following must occur prior to starting an ice making
cycle.
A. The bin level probe must be open (bin level
light off). If the probe is closed, (bin level light
on) when the toggle switch is moved to ICE,
the control system waits until the bin level
probe opens, (bin level light off) before
starting an ice making sequence. If the bin
level probe is removed/disconnected the ice
machine will not start.
B. The water level probe must be closed
(water level light on) to start the compressor.
If the water level probe is open, (water level
light off) the control system waits until the
water level probe closes before starting the
compressor.
INITIAL START-UP
1A. Flush
Immediately after placing the toggle switch into ICE,
the dump valve solenoid, and gearbox are energized.
After 45 seconds the dump valve de-energizes.
1B. Water Fill
After 45 seconds the water float valve solenoid is
energized.
2. Freeze Cycle
When water contacts the water level probe the
compressor and condenser fan motor energize
(condenser fan motor is wired through a fan cycling
control).
The gear motor, compressor, condenser fan motor and
water float valve solenoid remain energized as the ice
machine makes ice. The water float valve will open
and close automatically to maintain the proper water
level.
