Weather Last™ Wall Sleeve

Corrosion-Protected Polymer Sleeve

Part No.: WALL-SLEEVE-1PK

Part No.: WALL-SLEEVE-9PK

It is recommended that a Carrier sleeve be used with a

Carrier chassis. However, an accessory Retroﬁt Kit may

be ordered when ﬁtting a new 52S unit into an exist-

ing sleeve. See Accessory Retroﬁt Kit for GE Sleeve

on page 20 and Amana/Trane Sleeve on page 21.

The Carrier accessory wall sleeve is 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 polymer sleeve

absorbs sound, provides better insulation than a metal

sleeve, and offers years of protection against the

elements.

The beige (alpine mist) ﬁnish blends in well with in-

side or outside decor. The sleeve surface is textured to

prevent shine and hide scratches.

The sleeve is packaged in a heavy-duty cardboard car-

ton with an internal corrugated stiffener to reduce the

chance of damage during shipping and construction.

The rib conﬁguration on the sleeve bottom allows easy

chassis removal and aids in drainage. Water that over-

ﬂows the basepan is channeled along the ribs to the

drain openings on the back of the unit. The sleeve is

built with a pitch of

⁄

in. per foot, so there is no

need to adjust the sleeve during installation. Overﬂow

slots are in place to divert excess water during severe

weather. Locating holes in the side panels allow easy

fastening of the sleeve to wall openings. An accessory

drain kit is available, if needed. Refer to Drain Kit,

page 16, for the part number.

This sleeve accommodates all Carrier accessory grilles,

which simply snap in place and require no screws.

Refer to the 52S unit installation instructions for com-

plete sleeve and chassis installation procedures. Refer

to dimension drawings (pages 22-27) for typical wall

installation and unit dimensions.

When installing the Carrier wall sleeve, note the

following:

• If more than 4 in. of sleeve project 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-

tion of the Accessory Subbase on page 17 for the

part number.

• For all applications with an accessory subbase, wall

sleeve must exend 3

⁄

in. minimum into room and

must be 3

⁄

in. minimum to 5

⁄

in. maximum above

ﬂoor (including carpeting). Refer to wall sleeve in-

stallation instructions for further information.

• The Carrier sleeve must be mounted so that it is level

in all directions. See wall sleeve installation instruc-

tions for leveling procedure.

• The sleeve should be caulked on all sides, including

both inside and outside the building.
