C. Control Board<br />
• A <strong>Hoshizaki</strong> exclusive solid-state control board is employed in <strong>Hoshizaki</strong> Stackable<br />
Crescent Cubers.<br />
• All models are pretested and factory set.<br />
CAUTION<br />
1. The control board is fragile; handle very carefully.<br />
2. The control board contains integrated circuits, which are susceptible to failure<br />
due to static discharge. It is especially important to touch the metal part of<br />
the unit before handling or replacing the control board.<br />
3. Do not touch the electronic devices on the control board or the back of the<br />
control board.<br />
4. Do not change wiring and connections. Do not misconnect K3, K4,<br />
and K5, because the same connector is used for the thermistor,<br />
jumper (KM‐1301SAH-E) or mechanical bin control (KM-1301SWH-E,<br />
KM‐1301SRH-E), and float switch. KM-1301SAH-E utilizes a thermostatic bin<br />
control. For KM-1301SAH-E operation, the K4 jumper (4A4883G01) must be<br />
in place on the control board RED K4 connector.<br />
5. Always replace the whole control board assembly if it goes bad.<br />
6. Do not short out power supply to test for voltage.<br />
