4. Pump-Out Frequency Control (S4 dip switch 5 & 6)
NOTICE
Do not adjust on KM-515M_H without harvest pump timer. Adjustments to this setting
on KM-515M_H without harvest pump timer may adversely affect performance and
warranty coverage.
on KM-515M_H without harvest pump timer may adversely affect performance and
warranty coverage.
The pump-out frequency control is factory set to drain the water tank every 10 cycles
on all KM-320M_H, KM-600MAH, KM-650M_H, KM-901M_H/3 and on KM-515MAH
with harvest pump timer, and every cycle on KM-515M_H without harvest pump timer.
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 the control board. On "E" control boards, the
first pump-out is after the first freeze cycle. On "G" control boards, the first pump-out is
dependent on S4 dip switch 5 & 6. See the table below.

5. Bin Control Selector or Harvest Pump Timer Operation (S4 dip switch 7)
Depending on the control board, S4 dip switch 7 is used for either bin control selection or
harvest pump timer operation.
