4. Pump-Out Frequency Control (S4 dip switch 5 & 6)
The pump-out frequency control is factory set. 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 can be set to have
a pump-out occur every cycle, or every 2, 5, or 10 cycles.
The first pump-out is dependent on S4 dip switch 5 & 6. See the table below.

5. Harvest Pump Timer Operation (S4 dip switch 7)
Factory set for proper operation. Do not adjust. Adjustment outside of the factory
default setting may result in damage to the appliance.
Depending on the harvest pump timer setting, the pump motor either stays off or is
energized the last 50 seconds of harvest. When the pump motor is energized, water
circulates over the evaporator. The harvest water valve is open during harvest for a
maximum of 6 minutes or the length of harvest minus 0 or 50 seconds (determined by
the harvest pump timer setting), whichever is shorter.
When S4 dip switch 7 is in the on position and harvest begins, X11 and X10 relays
energize. A latching circuit is created through the X11 and X10 relays. For further details,
see "VIII.B. Wiring Diagrams."
50 sec. before harvest termination, LED 4 turns off, inlet water valve and X11 relay
de-energize. X10 relay remains energized through the latching circuit. Next, LED 3 turns
on and control board K1 connector pin #5 (DBU wire) energizes, energizing the pump
motor for the last 50 sec. of harvest.
6. Factory Use (S4 dip switch 8)
Factory set for proper operation. Do not adjust. This must be left in the factory default
position.
