Ice Thickness Adjustment

QM-20 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 QM-20 may appear to have a slightly larger dimple than other Manitowoc dice cube machines. Therefore, cube size for the QM-20 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.

WARNING

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

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.
