Install Instructions
Never drill or install fasteners through the top or
bottom of sleeve.
Protect wall sleeve during interior and exterior surface
cleaning from corrosive and acidic chemicals. These types of
chemicals will cause paint damage and premature rusting to
the wall sleeve.
DO NOT remove the thermal insulation from sleeve.
SELECTING SLEEVE LOCATION
Use the following guide for selecting the proper sleeve location:
1.
Allow at least 14 inches from front of wall sleeve for removal of
front panel and air conditioner for maintenance.
2.
The sleeve may be installed flush against the floor (including
carpeting), except for installations using a subbase. See SUBBASE
INSTALLATIONS section below.
3.
For cord-connected air conditioners, an electrical receptacle must be
located within reach of power cord.
Consult air conditioner
manufacturer's specifications for actual power cord length.
WALL PREPARATION
Proper attention to wall preparation, opening size and good construction
practices are essential to a trouble free sleeve installation.
Wall Opening Size
—
Recommended minimum wall opening is
42
1
/
4
in. wide x 16
1
/
8
in. high.
WOOD/STEEL FRAMING — Build a frame to the minimum wall
opening size to support the sleeve as shown in Figure 1.
MASONRY WALLS — Create the recommended minimum wall
opening, 42
1
/
4
in. wide x 16
1
/
8
in. high. The sleeve will not support
concrete block or bricks. Use proper sized lintels to support block or
bricks above wall opening. The sleeve should be fastened to masonry
walls with masonry screws (field supplied). If the opening is framed in
wood, use wood screws to secure the sleeve.
CURTAIN WALL —Use case angles to create the recommended
minimum wall opening, 42
1
/
4
in. wide x 16
1
/
8
in. high, for installations
such as curtain walls, window walls, or where the structural material of
the wall is insufficient to support or fasten the wall sleeve to. Case angles
are pieces of steel or similar material that are formed to a 90° angle. Add
holes to fasten the case angle to the sleeve and to the structural component
of the wall.
SLEEVE INSTALLATION
Step 1 Prepare Sleeve —
If grille is to be installed at this time, remove
and discard weather barrier panel and install rear grille per the
manufacturer's instructions. If condensate drain tube is to be installed at
this time, install per the manufacturer's instructions.
Step 2 Setting Sleeve —
Position the fully assembled sleeve in the wall
opening with the bottom down and the drain holes toward the outdoors.
Sleeve must extend at least
5
/
8
inches beyond building exterior to assure
proper drainage and to allow weather tight seal. Sleeve must extend at least
1
/
4
inches into room for proper weatherproofing.
Step 3 Leveling Sleeve — Place level in locations shown in
Figure 2.
Sleeve must be mounted level side to side and a 1/4
bubble tilt front to back. This allows for proper condensate drainage.
Step 4 Fastening Sleeve to Wall —
Locate and mark two (2) holes on
each side approximately 4-inches from the bottom and 4-inches from the
top.
Drill 3/16-in. pilot holes and use field supplied #10 x 1-in. stainless steel
screws, or appropriate fasteners for the wall construction, to secure sleeve
in place.
Check the sleeve is level side to side and a 1/4 bubble tilt front to back.
Adjust if necessary.
WEATHER PROOFING SLEEVE
Step 5 Exterior Weather Proofing — Proper weather proofing of all
sides between the wall surface and sleeve is essential to assure a trouble-
free installation.
Apply sealant, caulking or equivalent weather proofing material around the
perimeter of the sleeve to eliminate outdoor air and water leaks into the
room.
Note: Expandable foam insulation may be added to fill large wall gaps.
Apply per manufacturer's instructions.
Step 6 Interior Weather Proofing —
Apply sealant,
caulking or
equivalent weather proofing material to joints around the perimeter
(including bottom) of the sleeve to create a total air seal.
SUBBASE INSTALLATION
SUBBASE INSTALLATIONS
— When installing a subbase to support
the sleeve or for an electric receptacle for the power cord, the sleeve must
project 2
3
/
4
inches into the room to have room for the subbase and
receptacle box. The sleeve must be installed between 3
1
/
4
to 5
1
/
2
inches
(maximum) above floor (including carpeting).
IMPORTANT: If sleeve projects more than 4 inches into a room,
manufacturer recommends a subbase or leveling legs accessory to
prevent the sleeve from sagging or cantilevering into the room.
