Hoshizaki KMS-1401MLJ d Pump-Out Cycle, e Harvest Cycle, f Shutdown, After 11th freeze cycle

d) Pump-Out Cycle

LEDs 1, 3, and 2 are on. Comp and FMRs remain energized, HGVs and X10 relay energize. LLVs de‑energize. PM stops for 2 seconds, then X11 relay energizes, allowing PM and DV to energize for 10 or 20 seconds (S4 dip switch 3 & 4). Water is removed from the bottom of the water tank and sent down the drain. At the same time, water flows through the small F/S tube to power flush F/S. When the pump‑out timer terminates, pump-out is complete.

The 1st pump-out occurs after the 11th freeze cycle, then every 10th cycle thereafter. The pump-out frequency control is factory set, and generally no adjustment is required. However, where water quality is bad and the icemaker needs a pump-out more often, the pump-out frequency can be adjusted. The pump-out frequency control (S4 dip switch 5 & 6) can be set to have a pump-out occur every cycle, or every 2, 5, or

10 cycles. Timing of the first pump-out is dependent on S4 dip switch 5 & 6 settings. See the table below.

S4 Dip Switch Setting		Pump-Out	1st Pump-Out
No. 5	No. 6	Frequency
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

e) Harvest Cycle

LEDs 1, 4, and 2 are on. Same as the initial harvest cycle. See "II.B.1.b) Initial Harvest Cycle."

Note: Icemaker continues to cycle until BC is satisfied or power is turned off. The icemaker always restarts at the 1-minute fill cycle.

f)Shutdown

When BC is activated (BC open), the yellow "BC OPEN" LED comes on. The icemaker then shuts down as outlined in the table below.

Cycle at Bin	Shutdown
Control Activation
Fill Cycle	15 seconds after activation.
Harvest Cycle	At the end of the harvest cycle, or up to 15 seconds into the freeze cycle if activated
	at the end of the harvest cycle.
Freeze Cycle	15 seconds after activation if activated at least 15 seconds before the 5-minute short
	cycle protection timer terminates. Otherwise, at the end of the next harvest cycle.
