Ice Production Check
The QM20/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
QM20/QM30 may appear to have a slightly larger dimple
than other Manitowoc ice cube machines. Therefore, cube
size for the QM20/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.
Disconnect electric power to the ice machine at
the electric switch box before proceeding.
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 7 – 9 oz
(200 – 270 g). 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
4.
4. Remove the air filter.
5. Remove the two screws holding the front panel in place
and remove the front cover.
Locate the ice thickness control dial on the control board (see
figure). Turn the dial clockwise for a thicker cube or counter
clockwise for a thinner cube.
6. Ensure all of the panels and air filter are reinstalled
properly and the bin door is closed. Repeat steps 1 – 3.
