Hoshizaki SRH/3 KM-1400SWH-M, SRH/3 KM-2100SWH3, KM-1301SAH/3 Every cycle After 2nd freeze cycle

7)Pump-Out Cycle – LEDs 1, 3, and 2 are on (10/20 second pump-out).Timing of the first pump-out is determined by S4 dip switch 5 & 6. See the table below.

"G" Control Board Settings

S4 Dip Switch Setting		Pump-Out	1st Pump-Out
No. 5	No. 6	Frequency	"G" Control Board
OFF	OFF	Every cycle	After 2nd freeze cycle
ON	OFF	Every 2 cycles	After 3rd freeze cycle
OFF	ON	Every 5 cycles	After 6th freeze cycle
ON	ON	Every 10 cycles	After 11th freeze cycle

Comp and FMR continue, HGV energizes. If S4 dip switch 3 & 4 are set to 3 off and 4 on, LED 4 turns on and WV and X11 relay energize, energizing X10 relay.

NOTICE! S4 dip switch 3 & 4 must not be set to 3 off and 4 on. Otherwise, PM will rotate in freeze cycle direction instead of pump-out direction. FM and LLV de‑energize. PM stops for 2 sec., then reverses for 10/20 sec. depending on pump‑out timer (S4 dip switch 3 & 4) setting. When the pump‑out timer terminates, pump‑out is complete. The pump-out frequency control (S4 dip switch 5 & 6) is factory set, and generally no adjustment is required. However, the pump‑out frequency control can be set to have a pump-out occur every cycle, or every 2, 5, or 10 cycles. For details, see "III.C.4. Pump‑Out Frequency Control (S4 dip switch 5 & 6)."

Pump-Out Diagnosis: In the freeze cycle before pump-out (see table above), after 5 min. of freeze disconnect CB black K5 connector (FS connector). Check that PM stops and re-starts and that PM rotation is correct (water flowing down the drain through CV). If PM does not stop and re-start, check that CB LEDs 1, 3, and 2 are on. If not, replace CB. If LEDs 1, 3, and 2 are on and PM does not energize, check for 115VAC at CB K1 #5 (DBU) to neutral (W). If 115VAC is not present, replace CB. If 115VAC

is present, check that X10 relay is de-energized. If not, check X11 relay status. If X11 relay is energized, replace CB. If X11 relay is de-energized and X10 relay is energized, replace X11 relay (contacts sticking). If X10 relay is de-energized, check for 115VAC at terminal #6 (DBU) to neutral (W) and terminal #2 (DBU) to neutral (W). If 115VAC is present on terminal #6 (DBU) and not on terminal #2 (DBU), replace X10 relay. If PM is energized and rotating in pump-out rotation, make sure the drain line is not clogged and that CV is clean and operating properly.

Confirm FM and LLV de-energize. If FM or LLV are energized with LEDs 1, 3, and 2 on, replace CB.
