Section 3 Operation
Part Number 000006520 Rev 03 12/19 19
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 1/4" (6 mm) gap between
ice machine and evaporator as starting point, then
adjust to achieve a 1/8" (3 mm) 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.
Important
Scroll refrigeration compressors must be
operated for a minimum break in period of 24
hours before full ice production will be reached.
