other support must be employed. Support can be from a factory
supplied subbase or from other field supplied materials.
Recommended installation procedures are described below.
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 procedures. Install subbase before installing
cabinet/wall sleeve.
3. If the optional drain kit is to be employed (heat pump only),
refer to page 8 before proceeding.
4. Place a thin pad of soft mortar on the bottom of the opening
and slide in the cabinet/wall sleeve. Be sure to recess the wall
sleeve enough to accommodate outside louver. This recess
is

architectural louver. Louver should be flush to exterior
surface when complete. Note: The wall sleeve is not intended
to replace the lintel.
5. Level cabinet/wall sleeve in both directions and secure by
anchoring with appropriate fasteners (as shown in Figure C,
page 7). A

" (8mm) hole is provided on each side, 2" (51mm)
down from the top and 2" (51mm) in from the rear of the
cabinet/wall sleeve. Additional holes may be required to firmly
secure the cabinet/wall sleeve. Caution: Do not drill holes
in the base of the cabinet/wall sleeve. Where a subbase is
used, secure wall sleeve to subbase with clips provided.
6. 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 silicone.
