Operation

OPERATIONAL CHECKS

General
Manitowoc ice machines are factory-operated and adjusted
before shipment. Normally, new installations do 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 are
not covered by the warranty.

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 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 mm) thick.
2. If adjustment is necessary, turn the ice thickness probe
adjustment screw clockwise to increase bridge thickness,
counterclockwise to decrease bridge thickness. Set at
9/32" (7 mm) gap between ice thickness probe and
evaporator as starting point, then adjust to achieve a
1/8" (3 mm) bridge thickness.
NOTE: Turning the adjustment one-third of a turn will change
the ice thickness about 1.5 mm (1/16").
