Installation
The installation of this equipment shall be in accordance with the regulations of authorities having jurisdiction and all
applicable codes. It is the responsibility of the installer to determine and f ollow the applicable codes. Sheetmetal parts, sel ftapping screws, clips and such items inherently have sharp edges, and it is necessary that the installer exercise caution.
This equipment is to be installed only by an experienced installation company which employs trained personnel.
Inspection
When the equipment is received all items should be carefully
checked against the bill of lading to be sure all crates and
cartons have been received. All units should be carefully inspected
for damage when received. If any damage is noticed, the carrier
should make the proper notation on the delivery receipt acknowledging the damage. The carrier should also fill out a Carrier
Inspection Report. The McQuay International Traffic
Department should then be contacted.
The unit nameplate should be checked to make sure the
voltage agrees with the power supply available.

Wall Opening Requirement
Before installing the unit, check the wall opening to be sure the
cabinet/wall sleeve will slide into the opening unobstructed. For
masonry walls, a lintel must be used to provide support over each
opening. The rough opening should measure 16
1
42
/4" (1073mm) wide (see note ➂). When no subbase is used,
the opening should be a minimum of 3" (76mm) off the floor . This

/4" (413mm) X
distance may vary when a subbase is supplied. The standard
subbase is available in 3" (76mm) or 4" (102mm) heights. For
units with hydronic heat, the subbase is 81/4" (210mm). Each
subbase has leveling legs providing for up to 1" (25.4mm)
additional height.
Notes:
➀ Unit pictured with subbase installed. Subbase is optional on 208V and 230V units. Subbase is standard on all 265V units and units with hydronic heat.
➁ Subbase extends to front edge of unit when furnished with hydronic heat.
➂ Opening needs to be 16
④ Subbase side channels are adjustable from 43/8" to 133/4" (111mm to 349mm).

Wall Slee ve Installation — Frame and Brick
A heavy-gauge, corrosion resistant cabinet/wall sleeve is provided for each unit. The cabinet/wall sleeve is either shipped in a separate
carton, shipped in a multi-pack of 15 or in a single carton with the heating/cooling chassis.
The standard cabinet/wall sleeve is designed to be easily installed
in a variety of wall constructions. Note: The center of gravity is
1
10
/4" (260mm) from the rear face of the wall sleeve. The wall
sleeve must be inserted into the wall at least 101/4" (260mm) or
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
3
is
/8" (9.5mm) for stamped louvers and 11/4" (32mm) for
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
5
/16" (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.

Wall Sleeve Installation — Panel Wall Construction
For panel wall and thin wall construction, it is recommended that a louver frame be used. Refer to page 7 for installaton of louver frame
before continuing.
Panel wall and thin wall construction varies only slightly from frame
and brick construction. Note: The center of gravity is 10
1
/4"
(260mm) from the rear face of the wall sleeve. The wall sleeve
must be inserted into the wall at least 10
1
/4" (260mm) or other
support must be employed. Support can be from a factory supplied subbase or from other field supplied materials. Installation
for this application is as follows:
1. Clean the opening of all debris that may interfere with in-
stallation.
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 9 before proceeding.
4. Be sure the cabinet/wall sleeve is mechanically attached to
the wall and caulked to assure a proper seal. It is recommended that the louver frame be used for this purpose. (See
Figure B, page 7.)
5. Recess the wall sleeve so that the louver is flush with the
exterior of the building.
6. Level cabinet/wall sleeve in both directions and secure by
anchoring with appropriate fasteners (as shown in Figure C,
page 7) or drill additional holes as required to secure firmly.
Caution: Do not drill holes in the base of the cabinet/wall
sleeve. Where a subbase is used, secure wall sleeve to sub-
base with clips provided.
7. If no subbase is employed, proper support by installer must
be provided under wall sleeve, as shown in Figure 6.
8. 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 silicon.

Wall Sleeve Installation — Thick Wall Construction
Installation of cabinet/wall sleeves for thick walls requires special
consideration. Table 1 should be used to determine the
maximum wall thickness allowed for the standard cabinet/wall
sleeve. For thicker walls, cabinet/wall sleeve extensions are
available from your representative. Refer to page 7 for proper
installation of cabinet/wall sleeve extensions.
Cabinet/wall sleeve installation in thick walls is similar to frame
and brick installation. Install as follows:
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 9 before proceeding.
4. If wall thickness exceeds dimensions shown in Table 1, a
cabinet/wall sleeve extension must be used. Install the
extension as described on page 7. Once the extension is
attached to the cabinet/wall sleeve, place a thin pad of soft
mortar on the bottom of the opening and slide in the wall
sleeve/extension assembly . Be sure to recess the wall sleeve
3
enough to accommodate outside louver. This recess is
/8"
(9.5mm) for stamped louvers and 11/4" (32mm) for architectural louvers. Louver should be flush to exterior surface when
completed. 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) or drill additional holes as required to secure firmly.
Caution: Do not drill holes in the base of the cabinet/wall
sleeve. Where a subbase is used, secure wall sleeve to sub-
base 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.
