Waterproof barrier should remain in place until the unit is
installed. An accessory metal front panel, PBWMFC, is
also available, but must be purchased separately.
• Attach the sleeve using four #12x2” wood screws (for
wood constructed buildings) or four #12x2” masonry
screws (for cement or brick constructed buildings)
(Figure 6). Make sure the wall construction is ad-
equate to support the unit.

Wall Sleeve Installation
After the wall opening is checked and approved for strength,
location, size, and clearances, install the wall sleeve as
follows:
1. Remove the outside enclosure panel from the wall
sleeve.
2. Slide the wall sleeve into the wall opening. Do not
distort the cabinet shape to fit the wall opening; the unit
chassis must fit snugly and uniformly into the wall
sleeve.
3. Locate the sleeve within the range of minimum projec-
tions, as shown in Figure 2, so both sides are at least
the minimum projection from the wall.
4. Check the level of the wall sleeve. For proper drain-
age, the sleeve should be level from side to side and
one-quarter bubble front to back (outside).
5. Drill two holes in both sides of the wall sleeve so
mounting screws can be secured to wall supports.
See Figure 6 for location of screw holes. DO NOT
DRILL THROUGH BOTTOM OF SLEEVE.
6. Check the level of the wall sleeve and adjust if neces-
sary.
7. Caulk or seal around the outside of the entire sleeve.
8. If the unit chassis is not to be installed immediately,
replace the enclosure panel on the outside opening of
the sleeve to limit weather damage to the building
interior.
9. Recycle or dispose of packaging materials according
to local codes.
Condensate Drain Kit
An outdoor condensate drain kit (Figure 8) is available on
all models. An accessory drain kit, DK900D, is available
for internal drain applications and must be purchased
separately. The drain kit must be installed before installing
the wall sleeve in the wall. See the drain kit for actual
installation instructions.
