d) Pump-Out Cycle

LEDs 1, 3, and 2 are on. LED 4 is on when S4 dip switch 3 & 4 are set to 3 off and 4 on.
For details, see "II.C.3.c) Pump-Out Timer (S4 dip switch 3 & 4)." NOTICE! Do not
adjust S4 dip switch 3 & 4 to 3 off and 4 on. Adjustment to this position on this
model prevents the pump motor from rotating in the pump-out (reverse) direction.
Comp and FMR remain energized, HGVs energize. LLVs de-energize. PM de-energizes
for 2 seconds, then energizes in reverse direction for 10 seconds. Water is removed
from the bottom of the water tank and sent down the drain through the check valve. 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 pump-out timer and pump-out frequency control are factory set, and generally no
adjustment is required. However, where water quality is bad and the icemaker needs
a longer and/or more frequent pump-out, the pump-out timer and pump-out frequency
control can be adjusted. The pump-out timer (S4 dip switch 3 & 4) can be set to have a
10 or 20 second pump-out. For details, see "II.C.3.c) Pump-Out Timer (S4 dip switch 3 &
4)." The pump-out frequency control (S4 dip switch 5 & 6) can be adjusted as shown in
the table below. For details, see "II.C.3.d) Pump-Out Frequency Control (S4 dip switch
5 & 6)." 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), yellow "BC OPEN" LED turns on. The unit then shuts
down as outlined in the table below.

at the end of the harvest 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.
