The self-contained refrigerant system delivers cooling to the
desired space. Heating can be accomplished with electric
resistance with hydronic (water or steam), hydronic with in-
termediate electric resistance or with reverse cycle technol-
ogy (heat pump models only) as a special order. Generally,
an estimate for capacity selection is 35 BTUH per square
foot of oor space (cooling) and 4 BTUH (1.25 watts) per
cubic foot (heating). The architect or engineer must verify
the selection. Note that the heat pump reverse cycle gener-
ates approximately 10 BTUs per electrical watt as compared
to 3.4 BTUs per watt with resistance electric heat. The unit
will restart at its last setting after a power interruption.

Installing Wall Sleeve Extension
Wall sleeve extensions are shipped in a separate carton and
tagged to match the proper unit. Be sure to check tagging of
the extension against that of the unit. Install the wall sleeve
extension as follows:
1. Position the extension with standard wall sleeve so
proper alignment with drain and mounting holes is
achieved.
2. Place a bead of caulk around the perimeter of the wall
sleeve and another bead around the mating side of the
wall sleeve extension so that the joint is watertight. Do
not permit caulking to block the weep holes. Be sure to
use a resilient caulking such as silicone.
3. Assemble the wall sleeve extension to the wall sleeve.
Clean out weep holes to assure proper drainage.
4. Continue wall sleeve installation according to
instructions on page 8.
Residential and institutional cleaning compounds can
cause permanent damage to the packaged terminal
unit. To avoid damage to unit controls and heat trans-
fer surfaces, do not spray cleaning compounds onto
the discharge grille, return air opening, or unit controls.
Normal cleaning can be accomplished by wiping the
unit surface with a damp cloth. When using cleaning
compounds on carpets, oors or walls, turn the unit off
to avoid drawing potentially damaging vapors into the
package terminal unit.
Wall Opening Requirements
When roughing in the opening for the wall sleeve, make
certain there is sufcient clearance from the walls and oor.
The wall sleeve should be positioned a minimum of 5/8" in
from the room side nished wall to accommodate the room
cabinet. A minimum distance of 3" above the nished oor
is required for return air.
The rough opening should measure 16-1/4" high x 42-1/4"
wide. Before installing the unit, check the wall opening to be
sure the wall sleeve will slide into the opening unobstructed
and there is allowance for a 1/8" to 1/4" pitch inside to out-
side for proper sleeve drainage. For masonry walls, a lintel
must be used to provide support over each opening.
When using a louver frame, the opening must measure 16-
5/8" x 42-5/8". Louver frames should be used for panel wall
and thin wall applications to assure positive anchoring to the
wall (Figure 3).
The opening must start 4" above the nished oor (including
carpeting) to provide proper return air.
Installing Louver Frame
When a louver frame is used, it must be installed prior to, or
at the same time, as the wall sleeve, and it must be level and
square.
1. Apply caulking compound on the surfaces of the louver
frame’s four anges which will come in contact with the
wall. Add caulking as required for weather tight seal.
2. Insert the sleeve of the louver frame into the wall
opening from the exterior of the building and apply
rm pressure so that the caulked frame anges are snug
against the exterior of the building. Secure the louver
frame to the wall if desired.
3. Secure the louver frame to the wall through the sides and
top. Never secure the frame through the bottom as it may
cause leaks.
If the louver frame is to be installed in a panel wall, it should
be installed at the same time as the wall sleeve.

Installing Wall Sleeve
Thin Wall Construction
The standard wall sleeve is designed to be easily installed in
a variety of wall constructions. For panel wall and thin wall
construction, it is recommended that the optional top angle
be used and the wall sleeve be supplied with a turned down
ange (see Figure 8, 9 & 10).
The recommended procedure for installing units in panel
wall and thin wall construction is as follows:
1. Clean the opening of all debris that may interfere with
installation.
2. Recess the wall opening so that the louver is ush with
the exterior of the building. The center of gravity is
approximately 10-3/4" (273mm) from the rear face of
the standard wall sleeve. If a subbase is not used, eld
support must be provided up to the center of gravity. This
support can be metal, wood or concrete.
3. Level wall sleeve side to side and pitch to outside 1/4"/ft.
to assure proper sleeve drainage to outside. Anchor with
appropriate fasteners. Use holes provided (see Figure
14 on page 12) or drill additional holes as required to
secure rmly.
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.

Installing Wall Sleeve
Thin Wall Construction
Applications utilizing eld 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 11 illustrates a typical installation using a eld sup-
plied, continuous louver. This method is for illustration
purposes only. Other variations may be employed as long as
they meet Daikin's louver specications 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 ange) are eld supplied.
Installation of wall sleeves with continuous louvers is very
similar to that of applications with factory furnished louvers.
Assuming the louver meets the Daikin criteria, as stated
previously, 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 ush
with the exterior wall. Important: If the wall sleeve has
been installed into a thick wall, make certain the wall
sleeve protrudes into the room a minimum of 1-1/8"
(29mm) beyond the nished wall surface. This is 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 Figure
14 on page 12), or drill additional holes as required to
secure rmly.
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.
