Ice Thickness Check
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.
Do not touch electrical wires. Disconnect power to
the ice machine before making any ice thickness
adjustments.
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
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.
