c) Pump-Out Timer (S4 dip switch 3 & 4)
During cycles when a pump out is called for, 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-adjusted, and no adjustment is required.
T1: Time to drain the water tank
T: Harvest timer at pump out
Depending on the pump-out frequency control setting (dip switch 5 & 6), pump out
occurs every cycle, or every nd, 5th or 10th cycle.
d) Pump-Out Frequency Control (S4 dip switch 5 & 6)
The pump motor drains the water tank at the frequency set by the pump-out frequency
control.
The pump-out frequency control is factory-adjusted to drain the water tank every 10
cycles, and 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 as
shown in the table below.
