4. Pump-Out Frequency Control (S4 dip switch 5 & 6)

The pump-out frequency control is factory set. 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.

•"E" Control Board: Bin Control Selector (thermostatic or mechanical).

•"G" Control Board: Harvest Pump Timer Operation.

a)Bin Control Selector: "E" Control Board

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.
