•A Hoshizaki exclusive solid-state control board is employed in Hoshizaki Stackable Crescent Cubers.

•All models are pretested and factory set.

CAUTION

1.The control board is fragile; handle very carefully.

2.The control 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 before handling or replacing the control board.

3.Do not touch the electronic devices on the control board or the back of the control board.

4.Do not change wiring and connections. Do not misconnect K3, K4, and K5, because the same connector is used for the thermistor, jumper (KM‑1301SAH-E) or mechanical bin control (KM-1301SWH-E,
