D. Bin Control Check
When the actuator paddle is not engaged, BC is closed and the appliance produces ice.
S1 dip switch 7 must be in the "OFF" position. When ice lls the chute and engages
the actuator paddle, BC opens and CB shuts down the appliance within 10 seconds.
NOTICE! Do not place S1 dip switch 7 in the "ON" position. For details, see "III.C.1.
Default Dip Switch Settings."
