WARNING
Gloves should be worn to protect against cuts and/or pinched fingers. Failure to do so
could result in injury to hands.
Disengage the internal stowage hook of both flexible ducts and expand the ducts to their full length.
The ducts themselves are identical but can only be connected to the inlet and outlet ducts in one way. Air
flow direction tags are mounted to each duct to indicate the direction of air flow. The inlet duct collar is
outfitted with slots that accommodate pins on one duct. The outlet duct collar is outfitted with pins that
protrude inward to accommodate slots on the opposite end of the second duct.
