Ice Thickness Adjustment
QM30 dice ice cube formation is slightly different from
our previous models. Manitowoc ice machines have a
unique cube shape. It is normal to have a dimple in the
ice cube (a concave indentation in the cube). Ice cubes
from the QM30 may appear to have a slightly larger
dimple than other Manitowoc dice cube machines.
Therefore, cube size for the QM30 is determined by
measuring the slab weight (the combined weight of all
cubes from one harvest cycle). To determine proper slab
weight follow the instructions listed below.
Correct Ice Bridge Thickness
1. Ensure the air filter, front, and back panels are
installed properly and close the bin door.
2. During the third harvest cycle open the bin door and
catch the entire slab of ice.
3. Weigh the ice slab. The combined weight of all
cubes from one harvest should weigh between 200 -
270g (7 - 9-oz). If the slab weight is within this range,
the ice machine is working properly and no further
action is needed. If the slab weight is not within this
range or you desire a slightly thicker or thinner cube,
continue to step four.
4. Remove the air filter.
5. Remove the two screws holding the front panel in
place and remove the front cover.
6. Locate the ice thickness control dial on the control
board (see below). Turn the dial clockwise for a
thicker cube or counter clockwise for a thinner cube.

7. Assure all of the panels and air filter are reinstalled
properly and the bin door is closed. Repeat steps
one through three.
After completing the procedure above, if you are unable
to obtain a sheet of ice weighing 200 - 270g (7 - 9-oz)
contact the Manitowoc Service Department for further
assistance.
Do not touch electrical wires. Disconnect power to
the ice machine before making any ice thickness
adjustments.
