Control Board Features
FLUSH CYCLE
After the ice machine has completed 50 hours of run
time a flush sequence will start. This cycle will drain
and refill the evaporator to remove minerals that have
settled to the bottom of the evaporator. The flush
sequence lasts approximately 21 minutes, after which
the ice machine will reset the 50 hour counter and
automatically start ice making again.
POWER INTERRUPTION DELAY
If power is disconnected the ice machine stops. When
power is reapplied a 5 minute delay is initiated.
MAINTENANCE REQUIRED INDICATOR
The maintenance required light on Nugget Ice
Machines will energize and flash after 10,000 hours of
run time. The ice machine will need to be serviced to
ensure future reliability.
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.
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.
