erproofing Wall Sleeves section).
Wall Sleeve Installation
The wall sleeve may be installedfrom either the insideor
outsideofthe building.
Some builderswillattachthe wall sleeve to the support
wallthroughthe side supportangles whether they are
insertingthe sleeve fromthe outsideor the inside.Othem
willuse the side angles simplyas a locating"stop"to
achievethe appropriatedimensionwhileshootingfasten-
ersthroughthe sides of the wallsleeve intothe supporting
wall.In either case,the wall sleeve must be fastened to
the supporting wall and notto the finishedwall.
The sleeve may extend farther than 1"beyondthe finished
wall,but reachingthe perimeter of the openingfrom inside
for sealing becomes increasinglydifficult.In anycase,
adequate safety precautionsmust be consideredto
protectpersonnel.
Instailing Wall Sleeve from Inside
The most popular methodofinstallingthe wallsleeve is
from the inside of the buildingwiththe weather seal
appliedfrom the outsideas the finishwall isapplied.
Instalflng Wall Sleeve from Outside
In manyhigh-rise constructionapplications,contractors
insertthe wall sleevesfrom the outsidewhile thewall is
beingconstructed.The two-sidedsupport anglesshould
then be attached to the wall sleeve sides at a locationthat
willexceed the thicknessof the outsidefinish wall bythe
recommended3/8" to 1"dimension.
Forexample, ifthe supportingwall is concreteblockwith a
brickfacing, there is usuallya space betweenthe block
and the brick.This space dimensionmustbe added to the
widthof the brick (plus3/8" to 1")so thatwhen thesleeve
is inserted intothe blockwall opening, up tothe angles
and fastened to the blockwallbefore the brickisinstalled,
the sleevewilt protrudebeyondthefinished brickby3/8"
to 1",as needed for caulk sealing.
The same applies ifthe supportingwall iswoodframe.
One may insert the sleevefromthe outside upto the
angleslocated on each side,allowingforthe thicknessof
sheathing,finishsiding,and caulk sealing.
Recessed Sleeves
In someapplications,where either the buildingwallsare
verythick(over 16") or architecturaldesign dictates,units
can berecessed. Avoidrecessingthewall sleeve ifthe
wallopening is requiredto be the same size as the wall
sleeveopening. However,ifthe wall openingcan be larger
inverticaldimensionthan the wall sleeve sothat the
bottomcan rest ona sillthat isat least2" higher thanthe
bottomof thewall opening,some recessing ispermitted.
Thissillshouldbe recessed further than the sleeve by3/8"
to 1"to permitweather-seal caulking along the bottom
edge withoutpluggingthe drain holes in the sleeve.
The topof the wall opening should be above the topof the
wall sleevebya dimensionequal to or greater than the
amountof the recessin orderto avoidrestrictionofthe
condenserdischargeair.
Sealing/Weatherproofing Wall Sleeves
A highgrade non-hardeningcaulkingcompoundapproved
forexterioruse must be appliedoutsidearound the
perimeterof the wall sleeve and the finishedwall. Caulk
shouldalso be applied around thesleeve's perimeter and
thefinishedinteriorwall.
Final sealingagainstair infiltrationmust be done alter the
Magic-Pakunit is installedin thewall sleeve. Foradditional
protection,the space between the unit and the wall sleeve
shouldbe sealed on all sideswith a bead of sealant.
