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.
• 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.
• 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.
