4. Pump-Out Frequency Control (S1 dip switch 5 & 6)
The pump-out frequency control is factory set to drain the water tank every 10 cycles.
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
10 cycles.
The rst pump-out is dependent on S1 dip switch 5 & 6. See the table below.

NOTICE
Factory set for proper operation. Do not adjust. Adjustment outside of the factory
default setting may result in damage to the appliance.
The harvest pump timer allows the water valve to close and the pump motor to circulate
water in the tank during the nal part of harvest. The water valve is open during harvest
for a maximum of 6 minutes or the length of harvest minus 0, 10, 30, or 50 seconds
(determined by the harvest pump timer setting), whichever is shorter. When the water
valve closes, the pump motor energizes and runs for the time determined by the harvest
pump timer setting. The harvest pump timer is factory-adjusted, and no adjustment is
required.
