Wall Sleeve Installation Instructions (PDXWSA)
NOTE: Insure that the unit is only installed in a wall structurally adequate to support the unit including the sleeve, chassis and accessories.If the sleeve
projects more than 8" into the room, a subbase or other means of support MUST be used. Please read these instructions completely
before attempting installation.
WARNING
Falling Object Hazard
Not following Installation Instructions for
mounting your air conditioner can result
in property damage, injury, or death.
NOTICE
DO NOT allow any pitch toward the inside.
Flashing on all 4 sides of the opening is recommended.
Potential property damage can occur if instructions are
not followed.
For Deep Wall Installation (Greater than 13 1/4")
SeePage9
The following instructions apply ONLY to walls less than 13 ¼" in depth.
1 The PXDR10 Drain Kit,(optional for new construction) see page 10
if applicable, must be installed before the wall sleeve is installed
into the wall.
2 The External Drain (for new construction or unit replacement) see
page 11 if applicable, must be installed before the wall sleeve is
installed into the wall.

Typical Wall Sleeve Installation
3 From inside the building, position the wall sleeve in the opening and
push it into the wall until it protrudes at least ¼” on the outside
(See Figure 9, Page 8).
4 Position the wall sleeve with a slight tilt towards the outside to
facilitate condensate drainage. It should be level side-to-side and
the front should be ¼ bubble higher than the back.
