Ice Machine Operation Section 3
3-4 Part Number 80-1620-3
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.). Clean the water level probe with ice machine
cleaner, rinse thoroughly and re-check operation. 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" (.32 cm).
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" (.32 cm) 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” gap between ice
machine and evaporator as starting point, then
adjust to achieve a 1/8” 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.
