Ice Machine Operation Section 3

Part Number 000001528
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
1. Check the water level while the ice machine is in the
freeze mode and the water pump is running. The
correct water level is 1/8” - 1/2” (3-12.5 mm)
2. The float valve is factory set for the proper water
level. If adjustments are necessary:
A. Loosen the two screws on the float valve
bracket.
B. Raise or lower the float valve assembly as
necessary then tighten the screws.
C. If further adjustment is required, carefully bend
the float arm to achieve the correct water level.
WATER FLOAT VALVE CHECK
Before water will flow into the water trough the float
valve shut-off must be in the OPEN position.
ICE THICKNESS CHECK
After a harvest cycle, inspect the ice cubes in the ice
storage bin. The ice thickness probe is factory-set to
maintain the ice bridge thickness at 1/8" (3.2 mm).
NOTE: Make sure the water curtain is in place when
performing this check. It prevents water from splashing
out of the water trough.
1. Inspect the bridge connecting the cubes. It should
be about 1/8" (3.2 mm) thick.
2. If adjustment is necessary, turn the ice thickness
probe adjustment screw clockwise to increase
bridge thickness, counterclockwise to decrease
bridge thickness.
NOTE: Turning the adjustment 1/3 of a turn will change
the ice thickness about 1/16" (1.5 mm).
Ice Thickness Check
3. Make sure the ice thickness probe wire and the
bracket do not restrict movement of the probe.
