WSE WALL SLEEVE
Standard Grille
Premium, stamped galvanized steel
grille with powder coat paint. Ships
with sleeve. Galvanized steel inner
and outer weather panels also ship
with sleeve.
OPTIONAL INSTALLATION ACCESSORIES
DK / Drain Kit
Installed at the back of the unit and allows for
attachment to condensate disposal system, if
necessary or desired.
IDK/ Internal Drain Kit
New construction applications
where a condensate drain system
has been built into the wall interior.
BAK / Bafe Adapter Kit
Necessary when installing
in a sleeve deeper than 16
3/4" deep, such as Fedders
B sleeve (19 3/4" deep).
IMPORTANT:
Operating the air conditioner
with incorrect rear grille or
without Bafe Adapter Kit
(on 19 3/4” deep sleeve) will
recirculate discharge air and
cause compressor overload
to trip.
This will cause the unit
to shut down temporarily
and may lead to premature
compressor failure.
