WALL SLEEVES
Weather Lastt Wall Sleeve
For the best performance and longest life, Carrier
recommends genuine C arrier 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 m ust be installed level (any error should be
pitched to t he outside). Overflow slots on the outside
of the sl eev e are i n pl ace to d i vert exces s wat er
duri n g s ev ere weat her.
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 i nto 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
prot ect i o n an d ap pearan ce.
All Carri er’s poly m er wall sleev es are m ade 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 s l eeve s u rface is t ex t u red to prevent sh i n e 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 sl eev e’s al pi n e mi s t colo r (a s h ade of beig e)
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.
