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.
