1. Control Timer Board
• A HOSHIZAKI exclusive solid-state control timer board is employed in Hoshizaki flaker
icemakers.
• All models are pre-tested and factory-adjusted.
1. Fragile, handle very carefully.
. The control timer board contains integrated circuits, which are susceptible
to failure due to static discharge. It is especially important to touch the metal
part of the unit when handling or replacing the board.
3. Do not touch the electronic devices on the control timer board or the back of
the control timer board to prevent damage to the control timer board.
4. Do not change wiring and connections. Especially, never misconnect
terminals.
5. Do not short out power supply to test for voltage
6. Do not attempt to fix the electronic devices or parts on the control timer
board in the field. Always replace the whole control timer board if it goes bad.
The control timer board provides the following safeguards:
• Provides component protection during low water supply.
• Purges remaining ice in the evaporator.
