5. Bin Control Selector (S1 dip switch 7)
The bin control selector is factory set. Do not adjust. When used on a standard ice
storage bin, only the mechanical bin control should be used. When the mechanical
bin control is used (S1dip switch 7 in the off position), the gear motor delay after the
upper oat switch closes is 5 sec. WARNING! Do not place S1 dip switch 7 in the on
position on this model. This could lead to no ice operation, control board alarms,
or ice overow.

6a. Mechanical Shutdown Delay (S1 dip switch 8) Auxiliary Code E-0:
Not available when S1 dip switch 7 is on. Factory set for normal operation. No adjustment
is required. The shutdown delay is the time between the mechanical bin control proximity
switch opening and the control board shutting off the icemaker.

Not available when S1 dip switch 7 is on. Factory set for normal operation. No
adjustment is required. WARNING! Do not adjust S1 dip switch 8 out of the factory
default position. This dip switch must be left in the factory default position or the
appliance will not operate correctly.
