Notes:
1. Caulk entire perimeter of wall sleeve after installation.
2. Seal area between louver and wall sleeve to prevent condenser air recirculation.
3. Dimensions shown in table on page 6 do not apply to this application.

is field determined or specified. Angle is factory welded at given dimension when option is designated.
Wall Sleeve Installation —
Thin Wall Construction
Applications utilizing field supplied louvers require ad-
ditional considerations:
1. Louvers supplied by others must have 70% free area
or a pressure drop not exceeding 0.05 in. w.g. (12.45
Pa) at 300 fpm (1.524 m/sec) face velocity, and a blade
design that will not cause recirculation of air.
2. McQuay does not warrant the rain and water leakage
resistance of its equipment when used with louvers by
others.
3. All louvers by others must be approved by McQuay
engineering prior to installation.
Figure 12 illustrates a typical installation using a field
supplied, continuous louver. This method is for illustra-
tion purposes only. Other variations may be employed as
long as they meet McQuay's louver specifications listed
above and so long as adequate wall support is achieved.
All structural supports and fasteners (except the optional
top angle and turned down flange) are field supplied.
Installation of wall sleeves with continuous louvers is
very similar to that of applications with factory furnished
louvers. Assuming the louver meets the McQuay’s criteria,
as stated previously, proceed to install the wall sleeve as
follows:
1. Clean the opening of all debris that may interfere
with installation.

2. Position the wall sleeve into the wall so that it is flush
with the exterior wall.
Important:
If the wall sleeve
has been installed into a thick wall, make certain the
wall sleeve protrudes into the room a minimum of
1

/
8
" (29mm) beyond the finished wall surface. This
is to accommodate the heat section and room cabinet.
The center of gravity is 10
3
/
4
" (273mm) from the rear
face of the standard wall sleeve. If no subbase is being
employed, adequate support for the wall sleeve up to
the center of gravity must be provided at the job site.
This support can be wood, metal or concrete.
3. Level wall sleeve side to side and pitch to outside 1/8"/
ft. to assure proper sleeve drainage to outside. Anchor
with appropriate fasteners using holes provided (see
Figure 15, page 12), or drill additional holes as required
to secure firmly.
CAUTION
Do not drill holes in the base of the wall sleeve. Use shims
between the wall and the wall sleeve to prevent wall sleeve
distortion during anchoring.
4. Caulk the wall sleeve to the wall opening on both the
inside and outside perimeter. This can be done from the
inside of the building. Be careful
not
to plug the weep
holes.
