4. Pump-Out Frequency Control (S4 dip switch 5)
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 S4 dip switch 5. See the table below.
S4 Dip Switch Setting

No. 5
OFF Every 10 cycles After 11th freeze cycle
ON Every cycle After 2nd freeze cycle
5. Harvest Pump Time (Harvest Assist) (S4 dip switch 6)
NOTICE
Factory set for proper operation. Do not adjust. Adjustment outside of the factory
default setting may result in damage to the appliance.
Harvest pump time (harvest assist) is only active when S4 dip switch 7 is in the "ON"
position. In the factory default position, the harvest pump time (harvest assist) starts with
50sec. left to go in harvest cycle (S4 dip switch 6) and after the thermistor reaches 48°F
(9°C) at the evaporator outlet and the control board reads 3.9kΩ from the thermistor. The
harvest pump time (harvest assist) is factory set, and no adjustment is required.
