Control Board Features
POWER INTERRUPTION DELAY
If power is disconnected, the ice machine stops. When
power is reapplied, a 15-minute delay is initiated.
SAFEGUARDS
The ice machine control board has safety features to
protect the ice machine from severe failures. The ice
machine will stop when conditions arise that would cause
major component failure. Refer to Safeguards for details.
TOUCH PAD SEQUENCE OF OPERATION
1. The control board monitors the touch pad. Pressing/
selecting Ice, Water, or Ice & Water will energize
the corresponding blue Led selection and waits for
dispense lever or touchless sensor activation.
2. Depressing the dispense lever or activating the
touchless sensor closes the relay selected with the
touch pad. Depending on selection, either the water
solenoid, ice dispense motor or both components
activate.
WATER LEVEL CHECK
The float valve maintains the correct water level. The
water level is factory set and normally will not require
adjustment. The water level is correct if the Water Level
indicator light is energized and no water is entering the
overflow tube.
The float valve is secured with 2 stop nuts. If an
adjustment is required, raise or lower the stop nuts as
needed.
