3)Wipe down F/S assembly with a mixture of 1 part Hoshizaki "Scale Away" and 25 parts warm water. Rinse the assembly thoroughly with clean water.

4)While not necessary, the floats can be removed from the shaft during cleaning. If you remove them, note that the blue float is on top (UF/S) and the white float is on bottom (LF/S). The floats must be installed with the magnets inside them towards the top of the switch. See Fig. 6. Installing the floats upside down will affect the timing of F/S operation.

5)Rinse the float switch assembly thoroughly with clean water and replace in its correct position.

6)Plug the unit into the electrical outlet, then move the power switch to the "ON" position to start the automatic icemaking process.

7)Replace the front panel in its correct position.
