WALL SLEEVES
It is recommended that a Carrier sleeve be used with a
Carrier chassis.
Locating holes in the side panels allow easy fastening
of the sleeve to wall openings. Refer to dimension
drawings (pages 25 and 26) for typical wall installa-
tion and unit dimensions.
When installing any Carrier wall sleeve, note the
following:
• If more than 4 in. of sleeve projects into the room or
the wall is less than 2 in. thick, an accessory sub-
base must be used for support. Refer to the descrip-
tions of the Accessory Subbases on page 19 and 20.
• For all applications with an accessory subbase, wall
sleeve must extend 3
1
/
4
in. minimum into room and
must be 3
1
/
4
in. minimum to 5
1
/
2
in. maximum above
floor (including carpeting).
• All Carrier’s sleeves are self pitching and must be
mounted level in all directions. (Do not use rails to
level sleeve.)
• The sleeve should be caulked on all sides, including
both inside and outside the building.
Weather Last™ Wall Sleeve
Part No.: WALL-SLEEVE-1PK
Part No.: WALL-SLEEVE-9PK
The Carrier accessory wall sleeve is made from a
molded polymer that is designed for strength and dura-
bility. This material has excellent corrosion resistance
and a flammability rating of UL94-5V. The polymer
sleeve absorbs sound, provides better insulation than a
metal sleeve, and offers years of protection against the
elements.
The rib configuration on the sleeve bottom allows easy
chassis removal and aids in drainage. The sleeves are
built with a pitch of
1
/
4
in. per foot. Wall sleeves
must be installed level. Overflow slots are in place to
divert excess water during severe weather.
The alpine mist (a shade of beige) finish matches the
front panel and blends in well with inside or outside
decor. The sleeve surface is textured to prevent shine
and hide scratches.
Insulated Polymer Wall Sleeve
Part No.: SLEEVE-INSUL-1PK
Insulated polymer wall sleeves combine all of the
above features with the addition of factory-installed
insulation. The insulation helps to reduce heat loss,
save energy and provides better sound absorption over
the non-insulated sleeve.
Insulated Metal Wall Sleeves
Part No.: SLEEVE-STEEL-1PK
Part No.: SLEEVE-EXT24-1PK
Part No.: SLEEVE-EXT26-1PK
Part No.: SLEEVE-EXT28-1PK
Carrier’s new metal wall sleeves are available in a
variety of sizes for most applications and difficult
installations. All metal wall sleeves come with
factory-installed insulation, designed to minimize heat
loss and reduce outdoor noise transmissions into the
room. In addition, the metal wall sleeve provides a
flammability rating higher than UL94-5V.
Friedrich Retrofit Wall Sleeve
Adapter
Part No.: FR-SLEEVE-EXT
The Friedrich wall sleeve adapter is constructed of
sheet metal and is designed to increase the depth of
an existing Friedrich wall sleeve to accommodate
Carrier’s industry standard PTAC units.
