How do you attach an outlet air duct on an RV air conditioner?
Attach the outlet air duct to the base of the outdoor RV air conditioner from inside the vehicle using four truss head screws. Make sure the duct is positioned with the correct side facing down and that the markings for direction are aligned before tightening the screws.
Installing the Outlet Air Duct
Cut the four cable ties and position the outlet air duct at the base of the outdoor unit.
The duct must be installed from inside the RV using four truss head screws (#10). Align the duct so the up, down, left, and right markings face the correct directions. The side labeled “this face down” should rest against the bottom of the air conditioner.
Do not force or twist the duct once aligned. There is only one correct orientation that allows the mounting holes to line up evenly.
Tighten the screws until snug to create a secure connection between the duct and the air conditioner base.
