b)Mechanical Bin Control Cleaning

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

WARNING

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

1)Turn off the power supply.

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

3)Clear any ice away from the mechanical bin control.

4)Disconnect the bin control cable connector, then remove the mechanical bin control assembly from the unit.

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

6)Wipe down the mechanical bin control assembly with a mixture of 1 part Hoshizaki

"Scale Away" and 25 parts warm water. Rinse the parts thoroughly with clean water.

7)Reassemble the mechanical bin control assembly 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 the bin control cable connector.

9)Move the control switch to the "ICE" position.

10)Replace the front panel in its correct position.

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