Hoshizaki SRH/3 KM-1400SWH-M, SRH/3 KM-2100SWH3, KM-1301SAH/3, SWH/3 Pump-Out Timer S4 dip switch 3

3. Pump-Out Timer (S4 dip switch 3 & 4)

NOTICE

On models with harvest pump timer, do not adjust 3 off and 4 on. Pump does not run in pump-out rotation in this setting.

When a pump-out is called for, the pump motor stops for 2 sec., then energizes in the reverse direction, taking water from the bottom of the water tank and forcing pressure against the check valve seat allowing water to go through the check valve and down the drain. At the same time, water flows through the small tube to power flush the float switch. The pump motor drains the water tank for the time determined by the pump-out timer. The pump‑out timer also acts in place of the harvest timer during cycles with a pump‑out. The pump-out timer is factory set, and generally no adjustment is required. However, where water quality is bad and the icemaker needs a longer pump-out time, the pump‑out timer can be adjusted. The pump‑out timer control can be set to pump-out for 10 or 20 sec.
