Disconnect the tubing from the purge-air bag “T”-fitting, and then lay aside the
chassis-half containing the purge-air bag. (This step does not apply to models without
the purge air bladder bag.)

Note that these connectors may have been secured in place for shipping purposes
with hot-glue or wire ties. As necessary, carefully pry the hot-glue from each
connector or cut off the wire ties.

Using wire cutters, cut the two cable ties that secure the IR sensor to the chassis, and
then remove the sensor.
