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.
WATER LEVEL 
The water level sensor is set to maintain the proper 
water level above the water pump housing. The water 
level is not adjustable.
If the water level is incorrect, check the water level probe 
for damage (probe bent, etc.). Repair or replace the 
probe as necessary.

ICE THICKNESS CHECK
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).

3. Make sure the ice thickness probe wire and the 
bracket do not restrict movement of the probe.
