Wall Sleeve
For the best performance and longest life, Carrier
recommends genuine Carrier wall sleeves for all
installations.
All Carrier wall sleeves are built with a pitch of 1/4
in. per foot; for self--pitching of the unit, the wall
sleeve must be installed level (any error should be
pitched to the outside). Overflow slots on the outside
of the sleeve are in place to divert excess water
during severe weather.
Important Sleeve Installation Considerations:
S
All Carrier sleeves are self pitching and must
be mounted level in all directions. (Do not use
rails to level sleeve.)
S
The sleeve should be caulked on all sides,
including both inside and outside the
building.
S
If more than 4 in. of wall sleeve projects into
the room, an accessory subbase must be used
for support.
S
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) to allow for proper fit of
subbase.
S
For applications where the wall sleeve is
mounted flush to the exterior of the
building(or recessed in), Carrier recommends
a field--supplied drip edge be installed to
prevent water infiltration into the building.
S
Insulated wall sleeves should be considered
for superior sound absorption, to reduce heat
loss and to prevent sleeve sweating, a
condition that can occur when the outside
temperature is cold and the indoor conditions
are warm and humid.
Polymer Wall Sleeves
Choose a polymer wall sleeve for maximum
protection and appearance.
All Carrier’s polymer wall sleeves are made from a
molded polymer that is designed for strength and
durability. This material has excellent corrosion
resistance and a flammability rating of UL94--5V.
The sleeve surface is textured to prevent shine and
hide scratches. The rib configuration on the sleeve
bottom allows easy chassis removal and aids in
drainage. The locating holes in the side and top
panels allow for easy fastening of the sleeve to wall
openings. Refer to dimension drawings for typical
wall installation and dimensions.
The sleeve’s alpine mist color (a shade of beige)
closely matches the front panel and blends in well
with any inside or outside decor.
The polymer wall sleeve comes in both insulated
(factory installed) or non--insulated, to meet the
requirements of every application.
Insulated Polymer Wall Sleeve
Part No.: SLEEVE--INSUL--1PK
Carrier’s accessory insulated polymer wall sleeve,
with factory--installed insulation, provides superior
sound absorption, reduces heat loss and prevents
sleeve sweating, a condition that can occur when the
outside temperature is cold and the indoor conditions
are warm and humid.
IMPORTANT: Insulated Polymer Wall sleeve
provides superior sound absorption, reduces
heat loss and prevents sleeve sweating.

Corrosion--Protected Polymer Sleeve
Non--Insulated Polymer Wall Sleeve
Part No.: WALL--SLEEVE--1PK
Carrier’s accessory non--insulated polymer wall
sleeve provides a superior appearance and protection
for many applications.
For applications where weather conditions
could influence sleeve sweating, a condition
that can occur when the outside temperature is
cold and the indoor conditions are warm and
humid, the Insulated Polymer Wall sleeve
should be considered.
