Wall Sleeve Installation Instructions (PXWS)
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.

For Deep Wall Installation See Section II
The following instructions apply ONLY to walls less than
13 1/4" in depth.
1.
From inside the building, position the wall sleeve in the opening
and push it through the wall so it protrudes at least 1/4" on the
outside, note Figure 5.
2. 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 1/4 bubble higher than the back. DO
NOT allow any pitch toward the inside.
