1.Solid-State Timer Board Control

•A HOSHIZAKI exclusive solid-state sequence timer board is employed in Hoshizaki self- contained flaker icemakers.

•All models are pre-tested and factory-adjusted.

CAUTION

1.Fragile, handle very carefully.

2.The timer board contains CMOS (Complementary Metal-Oxide Semiconductor) 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 if it goes bad.

The timer board provides the following safeguards:

•Provides component protection during low water supply.

•Purges remaining ice in the evaporator.

•Provides short cycle protection for the compressor.
