6. Harvest Pump Time (Harvest Assist) (S4 dip switch 7)
NOTICE
Factory set for proper operation. Do not adjust. Adjustment outside of the factory
default setting may result in damage to the appliance.
Depending on S4 dip switch 7 setting, the pump motor either stays off or is energized
during the last seconds of the harvest cycle. When the pump motor is energized (S4 dip
switch 7 on), 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 the harvest pump time
value(S4 dip switch 6), 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." In the factory default position, 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
seconds of harvest. Harvest pump time adjusted by S4 dip switch 1 & 2 and S5 dip switch
4 settings. Contact Technical Support before adjusted these settings.
