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.

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.
