2. Float Switch Cleaning

Depending on local water conditions, scale may build up on F/S. Scale on the switch can cause the float to stick. In this case, F/S should be cleaned.

1)Turn off the power supply.

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

3)Remove the insulation panel, then remove the drain plug located on the lower front part of the ice chute. See Fig. 1. Allow the water tank to drain.

4)Replace the drain plug in its correct position. Be careful not to cross thread it.

5)Disconnect the vent tube and the flush tube from the top of F/S, then remove F/S assembly from the mounting bracket and remove the rubber boot from the bottom of F/S assembly. See Fig. 2.

6)Remove the retainer rod from the bottom of F/S assembly, then remove the float. Be careful not to bend the retainer rod excessively when removing it.

7)Wipe down F/S assembly's housing, shaft, float, and retainer rod with a mixture of 1 part Hoshizaki "Scale Away" and 25 parts warm water. Clean the inside of the rubber boot and hose with cleaning solution. Rinse the parts thoroughly with clean water.

8)Reassemble F/S assembly and replace it and the rubber boot in their correct positions. Reconnect the vent tube and the flush tube.

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

10)Replace the insulation panel and front panel in their correct positions.

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