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.

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 pumpout frequency can be adjusted. The pump-out frequency control can be set to have a pumpout 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 pumpout 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.

NOTICE

Do not adjust. This dip switch must be left in the factory default position or the icemaker will not operate correctly.

When set to on position on an icemaker with a thermostatic bin control, a 5-beep alarm sounds (open circuit) and the icemaker does not operate.
