c) Pump-Out Timer (dip switch 3 & 4)
When a freeze cycle is completed, the pump motor stops, and the icemaker resumes
operation in 2 seconds. Then, 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
T2: Harvest timer at pump out
Pump out always occurs on the 2nd harvest after startup. Then, depending on the pump-
out frequency control setting (dip switch 5 & 6), pump out occurs every cycle, or every
2nd, 5th or 10th cycle.
d) Pump-Out Frequency Control (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 drain more often, the pump-out frequency can be adjusted as
shown in the table below.
