5.
Level wall sleeve left to right, pitch it 1/4" bubble to the
outdoors and secure in wall with fasteners (as shown in
Figure C, page 12). A 5/16˝ hole is provided on each side,
2˝ down from the top and 2˝ in from the rear. Additional
holes may be required to firmly secure the wall sleeve.
Do not drill holes in the bottom of the wall sleeve as it
may cause leakage.
Where a subbase is used, secure the wall sleeve to the
subbase with the two clips provided (see subbase instal-
lation, page 8).
6.
Caulk the wall sleeve to the wall opening on both inside
and outside perimeter. Be careful not to plug the weep
holes. Caulking should be a resilient, non-hardening type,
such as silicone.
* Reduce these dimensions by the louver thickness
(
3/8"
or
1
1
⁄
8
"
) when using the outdoor drain kit. Sleeve must be
flush with or projecting past the building exterior
(see page 7).
Use Table 1 to determine the maximum wall thickness allowed
for the standard wall sleeve. For thicker walls, wall-sleeve ex-
tensions are available from your sales representative. Refer to
page 12 for proper installation of wall-sleeve extensions.
Wall sleeve installation in thick walls is similar to frame and
brick installation. The wall sleeve is not intended to replace
the lintel. Install as follows:
1.
Clean the opening of all debris that may interfere with
installation.
2.
If the unit is to be supplied with a subbase, refer to page
8 for installation procedure. Install subbase and wall sleeve
at the same time. (Subbase is required for 265V but is
optional for 208/230V.) A minimum of 4
3
⁄
8
˝ of wall sleeve
must project into the room when using a subbase.
3.
If the optional drain kit is to be employed (heat pumps
only), refer to page 7 before proceeding.
4.
If wall thickness exceeds dimensions shown in Table 1, a
wall-sleeve extension must be used. Install the extension
as described on page 12. Once the extension is attached to
the wall sleeve, place a thin pad of mastic on the bottom
of the opening and slide in the wall sleeve extension
assembly. Be sure to recess the wall sleeve enough to
accommodate outside louver. This recess is 3/8˝ for
stamped louvers and 1
1
⁄
8
˝ for architectural louvers. Lou-
vers should be flush to exterior surface when completed.
Note: Wall sleeve must be flush or projecting past
the exterior, if using the outdoor drain kit
(see page 7).
