Operational Checks

GENERAL

Your Manitowoc ice machine was factory-operated
and adjusted before shipment. Normally, a newly
installed ice machine does not require any
adjustment.
To ensure proper operation, always follow these
Operational Checks when starting the ice machine:
• for the first time
• after a prolonged out of service period
• after cleaning and sanitizing
Routine adjustments and maintenance procedures
outlined in this manual are not covered by the
warranty.
WATER LEVEL CHECK
1. Check the water level while the ice machine is in
the freeze mode and the water pump is running.
The correct water level is 1/8"-1/2" (3-12.5 mm)
above the water pump impeller housing.

B. Raise or lower the float valve assembly as
necessary, then tighten the screws.
C. If further adjustment is required, carefully
bend the float arm to achieve the correct
water level.
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 an ice bridge of 1/8 inch (3.2mm). If an
adjustment is needed, follow the steps below.
1. Turn the ice thickness probe adjustment screw
clockwise for a thicker ice bridge, or
counterclockwise for a thinner ice bridge.
IMPORTANT
It is normal for cubes to have a slight dimple. This
is a normal characteristic
Manitowoc's unique shape.
