Applications utilizing field supplied louvers require addi-
tional 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. Daikin 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 Daikin
engineering prior to installation.
Figure 7
illustrates a typical installation using a field sup-
plied, continuous louver. This method is for illustration
purposes only. Other variations may be employed as long as
they meet Daikin's louver specifications listed above and so
long as adequate wall support is achieved. All structural sup-
ports 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 Daikin's criteria, as stated previ-
ously, 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 is
installed into a thick wall it should be recessed 1-1/4", or
as required from the face of the exterior brick, so when
the louver is installed it is flush with the exterior face
of the building. The wall sleeve must protrude into the
room a minimum of 1-5/8" (29mm) beyond the finished
interior wall surface, 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
13 on page
11), 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.
