WALL SLEEVE INSTALLATION
After the wall opening is checked and approved for location,
size, and clearances, complete the following to install the wall
sleeve.
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 Figures 3 and 4, so both sides are at
least the minimum projection from the wall.
4. Check the level of the wall sleeve. For proper drainage,
the sleeve should be level from side to side and one-quar-
ter bubble in the sight glass sloping to the outside.
See Figure 10 for proper location to check wall sleeve with
level. The level should show a 1/4 bubble slope to the
outside.
Place level on dimples in wall sleeves’ corners.
For proper placement, level should show 1/4 bubble slope to the outside
in both the left and right hand corners.

NOTE: If using an internal drain kit, the sleeve must be level
from front to back.
See Figure 11 for proper location to check wall sleeve with
level. The sleeve should be level from side to side.
Place level on dimples or next to the dimples in wall sleeves’ corners.
For proper placement, sleeve should be level from front to back
in both the left and right hand corners.

5. Two holes will need to be drilled in both sides of the wall
sleeve for mounting into the wall. 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 SLEEVE. Figure 12 shows possible
fastening methods.

6. Check the level of the wall sleeve and adjust if necessary.
7. Caulk or seal around the outside of the entire sleeve.
8. If the unit chassis will not be installed immediately, re-
place the enclosure panel on the outside opening of the
sleeve. This will prevent weather damage to the building
interior.
9. Recycle or dispose of packaging materials per local codes.
