Non-ducted installations supply conditioned air into indoor room
areas without extensive duct work. The supply airstream is
directed by adjusting the 4-way supply grille to reach areas being
conditioned. The supply air mixes with the room air and cools or
heats occupants and/or equipment in the area. Unconditioned
room air is returned to the unit through the return grille. Avoid
supply air leaving supply grille and re-entering the unit return
grille without mixing with room air.

Outdoor Wall curbs are installed between the wall mount unit and
the outer wall surface. Wall curb use may avoid resizing supply
and return openings that are currently in an existing wall. Wall
curbs may also provide sound isolation and indoor area sound
reduction. Various curb options are available, and it is important to
select a curb that will meet the application requirements and also
be the correct size for the unit. Unit duct static requirements cannot
be exceeded when using a wall curb. Follow all instructions
provided with the wall curb when installing the product.

Ducted installations supply conditioned air into indoor room areas
using solid or flexible ducts. The supply air is distributed
throughout a single area or multiple areas. The supply air mixes
with the room air and cools or heats occupants and/or equipment.
Unconditioned room air is returned to the unit through a return
grille or return duct work. Avoid using restrictive duct work to
provide the best unit performance and efficiency. Review duct
static pressure requirements provided in this manual.
