Ice Thickness Adjustment
U65 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 U65 may appear to have a slightly larger dimple
than other Manitowoc dice cube machines. Therefore,
cube size for the U65 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.
Ice Thickness Adjustment Dial
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 Welbilt Service Department for
further assistance.

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