Operational Checks
GENERAL
Manitowoc ice machines are factory-operated and
adjusted before shipment. Normally, a newly installed ice
machine does not require any adjustment.
To ensure proper operation, always follow the
Operational Checks:
• when starting the ice machine for the first time
• after a prolonged out of service period
• after cleaning and sanitizing
NOTE: Routine adjustments and maintenance
procedures outlined in this manual are not covered by
the warranty.
WATER LEVEL CHECK
The float valve maintains the correct water level. The
water level must allow the water level probes to maintain
water contact throughout the freeze cycle. The water
level is factory set and normally will not require
adjustment. Check the water level during the freeze
cycle. The water level is correct if the water level
indicator light is energized (compressor is running) and
no water is entering the overflow tube. (Check for
overflow water exiting the ice machine drain line at the
floor drain.)
If adjustments are necessary:
A. Rotate float clockwise to increase water level
.
B. Rotate float counterclockwise to decrease water
level.
C. Verify the outlet for the water float valve is at a
20 to 30 degree angle to prevent contact with
the float.
