NOTICE
Factory set for proper operation. Do not adjust. Adjustment outside of the factory
default setting may result in damage to the appliance.
a) Harvest Pump Time (Harvest Assist)
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, 50 sec. before harvest
termination, LED 4 turns off, inlet water valve Next, LED 3 turns on and control board
K1connector pin #4 (R) 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 4settings.
Contact Technical Support before adjusted these settings.
b) Freeze-Time Correction
When S4 dip switch 7 is in the on position, freeze-time correction enabled.
