[a] Solid-State Control

1)A HOSHIZAKI exclusive solid-state control is employed in the self-contained flaker icemakers.

2)A printed circuit board (hereafter called “timer board”) includes a stable and high quality control system.

3)All models are pre-tested and factory-adjusted.

[b] Timer Board

CAUTION

1.Fragile, handle very carefully.

2.A timer board contains CMOS (Complementary Metal-Oxide Semicon- ductor) integrated circuits, which are susceptible to failure due to static discharge. It is especially important to use an anti-static wrist strap when handling or replacing the board.

3.Do not touch the electronic devices on the board or the back of the board to prevent damage to the board.

4.Do not change wiring and connections. Especially, never misconnect terminals.

5.Do not fix the electronic devices or parts on the board in the field. Always replace the whole board assembly when it goes bad.

The icemaker is controlled by the timer board for the following purposes:

1)To prevent the gear motor and the compressor from starting or stopping simultaneously.

2)To reduce remaining ice in the refrigeration casing.

3)To protect the unit in case of low water and low water pressure.

4)To protect the unit in case the bin control causes chattering.
