d) Pump-Out Cycle
LEDs 1, 4, 3, and 2 are on.
Comp and FMRs remain energized, HGVs and WV
energize. LLVs de-energize. PM stops for 2 seconds, then DVR energizes, energizing
PM and DV for 10 seconds. Water is removed from the bottom of the 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.
CAUTION! S4 dip switch
3 & 4 must remain in the factory default position of 3 off and 4 on. Otherwise,
DV will not energize during pump-out.
The first 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.

e) Harvest Cycle
Same as the initial harvest cycle. See "II.B.1.b) Initial Harvest Cycle."
Note: Unit continues to cycle until BC is satisfied or power is turned off. The unit always
restarts at the 1-minute fill cycle.
f) Shutdown
When BC is activated (BC open), the yellow "BC OPEN" LED comes on. The unit then
shuts down as outlined in the table below. For further details, see "IV.C. Bin Control
Check and Cleaning."

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.
