c) Pump-Out Timer (S4 dip switch 3 & 4)

CAUTION

Do not adjust S4 dip switch 3 off and S4 dip switch 4 on for this model. Otherwise, pump motor does not rotate in the pump-out direction.

When a pump-out is called for, the pump motor stops after the preceding freeze cycle. The pump motor restarts 2 seconds later in the reverse direction, taking water from the bottom of the 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 seconds.

d)Pump-Out Frequency Control (S4 dip switch 5 & 6)

The pump-out frequency control is factory set 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 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 2, 5, or 10 cycles.

Timing of the first pump‑out is dependent on S4 dip switch 5 & 6 settings. The first pump-out is factory set to occur after the 11th freeze cycle. See the table below.
