Wall Sleeve Installation Instructions (

Wall Sleeve Installation
After the wall opening is checked for location, size, and
clearances, proceed to wall sleeve installation.
1. Install Condensate Drain Kit (if applicable).
2. Slide the wall sleeve into the wall opening. The unit
chassis must fit snugly and uniformly into the wall
sleeve without distortion.
3. Make sure the sleeve is within the range of minimum
projections as outlined on the next page.
4. Level wall sleeve side-to-side. When using an
INTERNAL DRAIN with this unit, it is recom-
mended to install the wall sleeve in a level position
front-to-back within the wall. If the internal drain
was to clog up from lack of maintenance, water will
still overflow through the weep slots in the sleeve
near the louver and be directed outdoors. For proper
drainage, the sleeve should be level from side-to-side
and one-quarter bubble in the sight glass sloping to
the outside (if unit is to drain outside).
5. Secure the wall sleeve by anchoring with fasteners
through the sides and top. Drill holes of proper size
and in the proper location so the screws will engage
into strong supporting members of the wall. DO
NOT DRILL THROUGH BOTTOM OF WALL
SLEEVE. THIS CAN CAUSE LEAKAGE OF CON-
DENSATE WATER WITHIN THE WALLS.
6. Check the level of the wall sleeve and adjust if
necessary.
7. Caulk or seal around the outside of the entire
sleeve.
8. Recycle or dispose of packaging materials per local
codes.
note
The installer must determine and supply the
mounting bolts and/or screws to attach the
wall sleeve to the sides of the wall opening.
Make sure the wall opening is adequate for
strong support.
