LOCATION
1. Locate suitable location
along wall away from
prevailing winds. If
multiple units are to be
installed, units should
be spaced evenly
throughout the building
to provide balanced
airow.
2. Remove any insulation
or nonstructural
material from location.
CUTTING
3. Using chart on previous
page, determine
required rough opening
(RO) dimension (A) and
remove wall studs as
needed. (Fig. 1 & 2)
4. After studs are
removed, cut
appropriate sized RO in
outer wall. RO should
be centered between
remaining studs and
positioned so that
lowest point of the
RO will be at least 8ft
above oor level where
possible.
FRAMING
5. Using conventional
framing methods in
accordance with local
building requirements
and codes, build a
frame around the RO
to support the unit and
maintain structural
integrity of the wall as
needed. (Fig. 3)
SHEATHING (Optional)
6. Cover the inside
opening with plywood
sheathing cut to the
appropriate dimensions
as needed.
7. Cut a circular hole in the
plywood sheathing to
accept the shroud of the
unit being installed.

installed unit and inside
or outside RO may be
covered by additional
