c) Pump-Out Timer (S1 dip switch 3 & 4)
When a pump-out is called for, the pump motor de-energizes for 2 seconds, then the
pump motor and drain valve energize for 10/20 seconds. Water is removed from the
bottom of the water tank and pumped down the drain through the drain valve. At the
same time, water flows through the small float switch tube to power flush the float 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. However, where
water quality is bad and the icemaker needs a longer pump-out, the pump-out timer can
be adjusted. The pump-out timer can be set to have a 10 or 20 second pump-out.

T2: Harvest timer at pump-out
d) Pump-Out Frequency Control (S1 dip switch 5 & 6)
The pump-out frequency control is factory-adjusted to drain the water tank every
10 cycles, 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.
