13) Replace CB K8 connector in its correct position. Replace the control box cover in its
correct position.

2. Float Switch Cleaning
Depending on local water conditions, scale may build up on FS. Scale on FS can cause
inconsistent operation of UFS and LFS. In this case, both UFS and LFS should be
cleaned and checked.
1) Remove the front panel, then move the power switch to the "OFF" position.
2) Unplug the appliance from the electrical outlet.
3) Remove FS assembly from the reservoir cover. See Fig. 7.
4) Wipe down FS assembly with a mixture of 1 part Hoshizaki "Scale Away" and 25 parts
warm water. Rinse the assembly thoroughly with clean water.
5) 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 (UFS) and the white float is on bottom
(LFS). The floats must be installed with the magnets inside them towards the top of the
switch. See Fig. 4. Installing the floats upside down will affect the timing of FS operation.
6) Rinse the float switch assembly thoroughly with clean water and replace in its correct
position.
7) Plug the appliance into the electrical outlet, then move the power switch to the "ON"
position to start the automatic icemaking process.
8) Replace the front panel in its correct position.
