c) Pump-Out Timer (S4 dip switch 3 & 4)
The 1st pump-out occurs after the 11th freeze cycle, then every 10th cycle thereafter.
When a pump-out is called for, the X10relay is energized and the X13 relay is
de-energized to allow the drain valve to energize. The pump motor stops for 2seconds,
then the X11 relay energizes, allowing the pump motor and drain valve to energize.
Water is removed from the bottom of the water tank and sent down the drain. At the
same time, water ows through the small oat switch tube to power ush the oat switch.
The pump-out drains the water tank for the time determined by the pump-out timer. The
pump-out timer also acts in place of the harvest timer during cycles with a pump-out. The
pump-out timer is factory set, and generally no adjustment is required. The pump-out
timer control can be set to pump-out for 10 or 20 seconds.

d) Pump-Out Frequency Control (S4 dip switch 5 & 6)
The pump-out frequency control is factory-adjusted to drain the water tank every
10cycles, and generally no adjustment is required. However, where water quality is bad
and the icemaker needs a more frequent pump-out, the pump-out frequency can be
adjusted as shown in the table below.
Timing of the rst pump-out is dependent on S4 dip switch 5 & 6 settings. See the table
below.
