McQuay products feature our proven institutional grade
design and construction that allows you to benet from
the long life, reliability, and low sound levels, along
with higher energy efciencies for lower operating costs.
Plus, McQuay offers a nationwide network for original
equipment replacements with local parts and service.
McQuay® Applied Packaged Terminal Air Conditioners
and Heat Pumps are designed and built for through-thewall installation in either new or existing buildings. The
Figure 1. Exploded View of the 16" x 42" PDAC/PDHP with Top-Mounted Hydronic Unit
self-contained refrigerant system delivers cooling to the
desired space. Heating can be accomplished with electric
resistance, with hydronic (water or steam), hydronic
with intermediate electric resistance or with reverse
cycle technology (heat pump models only). 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 generates 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.

WARNING
Residential and institutional cleaning compounds can cause
permanent damage to the packaged terminal unit. To avoid
damage to unit controls and heat transfer 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 sufcient 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 16¼" high x 42¼"
wide. Before installing the unit, check the wall opening
to be sure the wall sleeve will slide into the opening
unobstructed. For masonry walls, a lintel must be used to
provide support over each opening.
When using a louver frame, the opening must measure
165/8" x 425/8". Louver frames should be used for
panel wall and thin wall applications to assure positive
anchoring to the wall (Figure 4).
The opening must start 4" above the nished oor
(including carpeting) to provide proper return air.
Louver Frame Installation
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 lou
ver 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.

Note: Wall Sleeve rough opening when using a Louver Frame must
be 165/8" x 425/8"
Wall Sleeve Extension Installation
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.

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 Figures 9, 10 & 11).
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 103⁄4" (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 1/8"/ft.
to assure proper sleeve drainage to outside. Anchor with
appropriate fasteners. Use holes provided (see Figure 15,
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.
Note: When using recessed louver wall sleeve, level and plumb wall
sleeve using the top and sides of the sleeve and the chassis slide rails.
DO NOT level using the bottom of the wall sleeve as it has a built in
pitch to drain.

Wall Sleeve Installation —
Thin Wall Construction
Applications utilizing eld supplied louvers require additional 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. McQuay 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 McQuay
engineering prior to installation.
Figure 12 illustrates a typical installation using a eld
supplied, continuous louver. This method is for illustration purposes only. Other variations may be employed as
long as they meet McQuay's louver specications listed
above and so long as adequate wall support is achieved.
All structural supports 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 McQuay’s 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
11/8" (29mm) beyond the nished wall surface. This
is to accommodate the heat section and room cabinet.
The center of gravity is 103/4" (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 15, 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.

Wall Sleeve Installation —
Thick Wall Construction
A heavy-gauge, corrosion resistant wall sleeve is provided
for each unit. The wall sleeve is either shipped in a separate
carton or shipped in a multi-pack of 15.
Typical installation for masonry walls is shown in Figure
13. The recommended installation procedure for this type
of construction is as follows:
1. Clean the opening of all debris that may interfere with
installation.
2. Be sure the unit’s center of gravity falls within the load
bearing surface of the wall. The center of gravity for
the unit is approximately 103⁄4" (273mm) from the rear
edge of the wall sleeve. If the center of gravity is not
within the load bearing surface, then additional support
such as wood, metal or concrete must be provided in
the eld.
3. Place a thin pad of soft mortar on the bottom of the
opening. Important: Make certain the wall sleeve
protrudes into the room a minimum of 11⁄8" (29mm)
beyond the nished wall surface to accommodate the
heat section and room cabinet. Be sure to recess the wall
sleeve enough to accommodate outside louver. This
recess is 3/8" (9.5mm) for stamped louvers and 11⁄4"
(32mm) for architectural louvers. The louver should
be ush to exterior surface when completed.
4. If a brickstop is employed (as shown in Figure 5), slide
the wall sleeve into the wall until the brickstop contacts
the exterior bricks, as illustrated below. If a brickstop
is not used, slide the wall sleeve in the wall so that
it extends into the room a minimum of 11⁄8" (29mm)
beyond the nished interior wall surface. This allows
room to attach the heat section and room cabinet. The
wall sleeve should also be recessed enough to accommodate the outside louver. Level wall sleeve side to
side and pitch to outside 1/8"/ft. to assure proper sleeve
drainage to outside.
5. After the mortar has dried, remove the masonry sup
port from the wall sleeve. Note: The wall sleeve is not
intended to replace the lintel.
6. Anchor with appropriate fasteners (as shown in Figure
15, page 12). A 5/16" (8mm) hole is provided on each
side, 2" (51mm) down from the top and 2" (51mm)
in from the rear of the wall sleeve. It may necessary
to drill additional holes in the wall sleeve to rmly
secure it.
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.
7. Caulk the wall sleeve to the wall opening on both the
in-side and outside perimeter using a resilient, nonhardening caulk such as silicone. Be careful not to
plug the weep holes.
