Weather Last™ Wall 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
existing sleeve. See Accessory Retrofit Kit for GE
Sleeve on page 19 and Amana/Trane Sleeve on
page 20.
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 beige (alpine mist) finish blends in well with
inside or outside decor. The sleeve surface is textured
to prevent shine and hide scratches.
The sleeve is packaged in a heavy-duty cardboard
carton with an internal corrugated stiffener to re-
duce 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 1 /

need to adjust the sleeve during installation. Over-
flow 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 15, for the part number.
This sleeve accommodates all Carrier accessory
grilles.
Refer to the 52S unit installation instructions for com-
plete sleeve and chassis installation procedures. Refer
to dimension drawings (pages 21-26) for typical wall
installation and unit dimensions.
