Drain Frequency Control

Infrared Sensor Shutdown Delay

2. Infrared Sensor Shutdown Delay (S1 dip switch 1, 2, 3)

NOTICE

Do not adjust. Setting not used on this model. When dip switch 7 is off, 1, 2, and 3 are ignored.

Factory set. DCM-751B_H(-OS) does not use an infrared sensor bin control. The appliance uses a mechanical bin control for ice level control.

3. Drain Frequency Control (S1 dip switch 4)

The appliance is factory set for optimum performance with the 1-in-1 drain cycle (S1 dip switch 4 in the "OFF" position). This setting allows for removal of sediment from the evaporator without interrupting the icemaking process. 1-in-12 drain cycle is available.
