3. Pump-Out Timer (S4 dip switch 3 & 4)
NOTICE
On models with harvest pump timer, do not adjust 3 off and 4 on. Pump does not
run in pump-out rotation in this setting.
run in pump-out rotation in this setting.
When a pump-out is called for, the pump motor stops for 2 sec., then energizes in the
reverse direction, taking water from the bottom of the water tank and forcing pressure
against the check valve seat allowing water to go through the check valve and down
the drain. At the same time, water flows through the small tube to power flush the float
switch. The pump motor 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 time, the
pump-out timer can be adjusted. The pump-out timer control can be set to pump-out for
10 or 20 sec.
