2. Float Switch Cleaning
Depending on local water conditions, scale may build up on FS. Scale on the switch can
cause the oat to stick. In this case, FS should be cleaned.
1) Remove the front panel, then move the control switch to the "SERVICE" position. Move
the service switch to the "DRAIN" position.
2) Allow the water to drain from the water tank, then move the control switch to the "OFF"
position. Turn off the power supply.
6) Remove the FS from the PM bracket and water tank.
7) Remove the retainer rod from the bottom of FS housing, then remove the oat.
Becareful not to bend the retainer rod excessively when removing it. See Fig. 3.
6) Wipe down FS housing, shaft, oat, and retainer rod with a mixture of 1 part Hoshizaki
"Scale Away" and 25 parts warm water. Rinse the parts thoroughly with clean water.
7) Reassemble FS assembly and replace it in its correct position.
8) Move the control switch to the "ICE" position.
9) Replace the front panel in its correct position.
10) Turn on the power supply to start the automatic icemaking process.
