Pump-out cycle always occurs on the 2nd harvest after startup. Then, depending on the
pump-out frequency control setting (S1 dip switch 5 & 6), pump-out cycle occurs every
cycle, or every 2nd, 5th, or 10th cycle.
d) Pump-Out Frequency Control (S1 dip switch 5 & 6)
The water tank drains 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.

e) Harvest Pump Timer (S1 dip switch 7 & 8)
The harvest pump timer allows the water valve to close and the pump motor to circulate
water in the tank during the fi nal part of harvest. The water valve is open during harvest
for a maximum of 6 minutes or the length of harvest minus 0, 10, 30, or 50 seconds
(determined by the harvest pump timer setting), whichever is shorter. When the water
valve closes, the pump motor energizes and runs for the time determined by the harvest
pump timer setting.
The harvest pump timer is factory-adjusted, and no adjustment is required.

f) Freeze Timer (S1 dip switch 9 & 10)
Adjust to proper specifi cation, or the unit may not operate correctly.

possible freeze-up issues. Upon termination of freeze timer, machine initiates the
harvest cycle. After 2 consecutive timer terminations, machine will shut down, possibly
indicating a problem.
