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 approximately 1/8" (3 mm) thick and the cubes
should have a slight dimple.
2. If adjustment is necessary, turn the ice thickness
probe adjustment screw clockwise to increase
bridge thickness and counterclockwise to decrease
bridge thickness. Set at 9/32" (7 mm) gap between
ice thickness probe and evaporator as a 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).
3. Make sure the ice thickness probe wire doesn't
restrict movement of the probe.
Part Number 000007345 2/14
NOTE: During shipping and installation the ice thickness
probe may shift, requiring further adjustment to achieve
the rated energy efficiency and production. The ice
weight per cycle must be within the minimum and
maximum for your ice machine series. Capture and
weigh the ice from the second freeze/harvest cycle. The
target weight is the middle of the minimum and
maximum weight in the chart below.
