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 ows through the small F/S tube to power ush 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&
