(260mm) from the rear face of the wall sleeve. The wall sleeve
must be inserted into the wall at least 10

support must be employed. Support can be from a factory sup-
plied subbase or from other field supplied materials. Installation
for this application is as follows:
1. Clean the opening of all debris that may interfere with in-
stallation.
2. If the unit is to be supplied with a subbase, refer to page 8 for
installation procedures. Install subbase before installing cabi-
net/wall sleeve.
3. If the optional drain kit is to be employed (heat pump only),
refer to page 9 before proceeding.
4. Be sure the cabinet/wall sleeve is mechanically attached to
the wall and caulked to assure a proper seal. It is recom-
mended that the louver frame be used for this purpose. (See
Figure B, page 7.)
5. Recess the wall sleeve so that the louver is flush with the
exterior of the building.
6. Level cabinet/wall sleeve in both directions and secure by
anchoring with appropriate fasteners (as shown in Figure C,
page 7) or drill additional holes as required to secure firmly.
Caution: Do not drill holes in the base of the cabinet/wall
sleeve. Where a subbase is used, secure wall sleeve to sub-
base with clips provided.
7. If no subbase is employed, proper support by installer must
be provided under wall sleeve, as shown in Figure 6.
8. Caulk the cabinet/wall sleeve to the wall opening on both the
inside and outside perimeter. Be careful not to plug the weep
holes. Caulking should be resilient, non-hardening type such
as silicon.
Wall Sleeve Installation — Panel Wall Construction
For panel wall and thin wall construction, it is recommended that a louver frame be used. Refer to page 7 for installaton of louver frame
before continuing.
