2. Bin Control Cleaning
Scale may build up on BC. Scale can cause the actuator paddle and magnet to stick. In
this case, BC should be cleaned.
WARNING
CHOKING HAZARD: Ensure all components, fasteners, and thumbscrews are
securely in place after the icemaker is serviced. Make sure that none have fallen
into the dispense unit/ice 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 BC.
4) Disconnect BC connector from CB K4 connector, then remove BC from the icemaker.
5) Remove the actuator paddle from the switch mount. See Fig. 2.
6) Wipe down BC with a mixture of 1 part of Hoshizaki "Scale Away" and 25 parts of warm
water. Rinse the parts thoroughly with clean water.
7) Reassemble BC 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 BC connector to CB K4 connector, then move the control switch to the "ICE"
position.
9) Replace the control box cover in its correct position.
10) Turn on the power supply to start the automatic icemaking process.
11) Replace the front panel in its correct position.
