b)Mechanical Bin Control Cleaning

Scale may build up on MBC. Scale can cause the actuator paddle and magnet to stick. In this case, MBC should be cleaned.

WARNING

CHOKING HAZARD: Ensure all components, fasteners, and thumbscrews are securely in place after the icemaker is serviced. Make sure that none have fallen into the dispense unit/ice storage bin.

1)Turn off the power supply.

2)Remove the front panel and base cover, then move the control switch to the "OFF" position.

3)Clear any ice away from MBC.

4)Disconnect MBC connector from CB K4 connector, then remove MBC from the icemaker.

5)Remove the actuator paddle from the switch mount. See Fig. 2.

6)Wipe down MBC with a mixture of 1 part of Hoshizaki "Scale Away" and 25 parts of warm water. Rinse the parts thoroughly with clean water.

7)Reassemble MBC and replace it in its correct position.

Note: If the magnet was removed for cleaning, be sure to replace it in its correct position.

8)Reconnect MBC connector to CB K4 connector, then move the control switch to the "ICE" position.

9)Replace the control box cover and base cover in their correct positions.

10)Turn on the power supply to start the automatic icemaking process.

11)Replace the front panel in its correct position.
