WALL MOUNT GENERAL INFORMATION
AIR CONDITIONER WALL MOUNT MODEL NOMENCLATURE
W48 A 1 2 A 10 B X X X X A
NOTE: Vent option B is without exhaust capability. May require separate field supplied barometric relief in building.
SHIPPING DAMAGE
Upon receipt of equipment, the carton should be
checked for external signs of shipping damage. If
damage is found, the receiving party must contact the
last carrier immediately, preferably in writing,
requesting inspection by the carrier’s agent.
GENERAL
The equipment covered in this manual is to be installed
by trained, experienced service and installation
technicians.
The refrigerant system is completely assembled and
charged. All internal wiring is complete.
The unit is designed for use with or without duct work.
Flanges are provided for attaching the supply and return
ducts.
These instructions explain the recommended method to
install the air cooled self-contained unit and the
electrical wiring connections to the unit.
These instructions and any instructions packaged with
any separate equipment required to make up the entire
air conditioning system should be carefully read before
beginning the installation. Note particularly “Starting
Procedure” and any tags and/or labels attached to the
equipment.
While these instructions are intended as a general
recommended guide, they do not supersede any national
and/or local codes in any way. Authorities having
jurisdiction should be consulted before the installation is
made. See Page 3 for information on codes and
standards.
Size of unit for a proposed installation should be based
on heat loss calculation made according to methods of
Air Conditioning Contractors of America (ACCA). The
air duct should be installed in accordance with the
Standards of the National Fire Protection Association
for the Installation of Air Conditioning and Ventilating
Systems of Other Than Residence Type, NFPA No.
90A, and Residence Type Warm Air Heating and Air
Conditioning Systems, NFPA No. 90B. Where local
regulations are at a variance with instructions, installer
should adhere to local codes.

DUCT WORK
All duct work, supply and return, must be properly sized
for the design airflow requirement of the equipment.
Air Conditioning Contractors of America (ACCA) is an
excellent guide to proper sizing. All duct work or
portions thereof not in the conditioned space should be
properly insulated in order to both conserve energy and
prevent condensation or moisture damage.
Refer to Maximum ESP of operation Electric Heat
Table.
Design the duct work according to methods given by the
AirConditioning Contractors of America (ACCA).
When duct runs through unheated spaces, it should be
insulated with a minimum of one inch of insulation. Use
insulation with a vapor barrier on the outside of the
insulation. Flexible joints should be used to connect the
duct work to the equipment in order to keep the noise
transmissiontoaminimum.
For model series W48, W60 and W70, a 1/4 inch
clearance to combustible material for the first three feet
of duct attached to the outlet air frame is required. See
Wall Mounting Instructions and Figures for further
details.
Ducts through the walls must be insulated and all joints
taped or sealed to prevent air or moisture entering the
wallcavity.
Some installations may not require any return air duct. A
metallic return air grille is required with installations not
requiring a return air duct. The spacing between louvers
on the grille shall not be larger than 5/8 inch.
Any grille that meets with 5/8 inch louver criteria may be
used. It is recommended that Bard Return Air Grille Kit
RG2 through RG5 or RFG2 through RFG5 be installed
when no return duct is used. Contact distributor or
factory for ordering information. If using a return air
filter grille, filters must be of sufficient size to allow a
maximum velocity of 400 fpm.
NOTE: If no return air duct is used, applicable
installation codes may limit this cabinet to
installation only in a single story structure.
CONDENSATE DRAIN
A plastic drain hose extends from the drain pan at the
top of the unit down to the unit base. There are
openings in the unit base for the drain hose to pass
through. In the event the drain hose is connected to a
drain system of some type, it must be an open or vented
type system to assure proper drainage.
FILTERS
W48A12, W48L12 & W60A12, W60L12 ONLY
A 1-inch throw away filter is supplied with each unit.
The filter slides into position making it easy to service.
This filter can be serviced from the outside by removing
the service door. A 1-inch washable filter and a 2-inch
pleated filter are also available as optional accessories.
The internal filter brackets are adjustable to
accommodate the 2-inch filter by bending the metal tabs
holding the 1-inch filter down. There are two tabs on
each side of the filter.
NOTE: W48A13, W48L13, W60A13, W60L13 and
W70A13, W70L13 models require the use of a
return air filter grille.

NOTE: For side by side installation of two (2) W**A models there
must be 20" between units. This can be reduced to 15" by using
a W**L model (left side compressor and controls) for the left unit
and WA (right side compressor and controls) for right unit.
See W**A Specification S3397 & W**L Specification S3400
and Specification Sheet S3409 for 6-Ton W**A / W**L.
INSTALLATION INSTRUCTIONS
WALL MOUNTING INFORMATION
1.
Two holes for the supply and return air openings must
be cut through the wall as shown in Figure 1 or 2.
Figure 1 is for models W48A13 and W60A13.
Figure 2 is for models W48A12 and W60A13.
Figure 3 is for models W48L13 and W60L13.
Figure 4 is for models W48L12 and W60L12
Figure 5 is for model W70A13
Figure 6 is for model W70L13
2. On wood frame walls, the wall construction must be
strong and rigid enough to carry the weight of the
unit without transmitting any unit vibration.
3. Concrete block walls must be thoroughly inspected
to insure that they are capable of carrying the weight
of the installed unit.
W48A12, W48L12 & W60A12, W60L12 ONLY
These units are equipped with adjustable return and
supply air flanges. The flanges are adjustable side to side
in 1" increments. This allows these units to be adjusted
so that in side by side applications these units can replace
two 2 Ton units using the same wall openings.
MOUNTING THE UNIT
1. These units are secured by wall mounting brackets
which secure the unit to the outside wall surface at
both sides. A bottom mounting bracket is provided
for ease of installation, but is not required.
2.
The unit itself is suitable for 0 inch clearance, but the
supply air duct flange and the first 3 feet of supply air
duct require a minimum of 1/4 inch clearance to
combustible material. If a combustible wall use a
minimum of 30½" x 10½" dimensions for sizing.
However, it is generally recommended that a 1 inch
clearance is used for ease of installation and maintaining
the required clearance to combustible material. The
supply air opening would then be 32" x 12".
3. Locate and mark lag bolt locations and bottom
mounting bracket location.
4. Mount bottom mounting bracket.
5.
Hook top rain flashing under back bend of top. Top rain
flashing is shipped secured to the right side of the back.
6.
Position unit in opening and secure with 5/16 lag bolts;
use 7/8 inch diameter flat washers on the lag bolts.
7. Secure rain flashing to wall and caulk across entire
length of top.
8. For additional mounting rigidity, the return air and
supply air frames or collars can be drilled and
screwed or welded to the structural wall itself
(depending upon wall construction). Be sure to
observe required clearance if combustible wall.
9. On side by side installations, maintain a minimum of
20 inches clearance on right side to allow access to
control panel and heat strips, and to allow proper
airflow to the outdoor coil. Additional clearance
may be required to meet local or national codes.
WARNING
Fire hazard can result if 1/4 inch clearance to
combustible materials for supply air duct is
not maintained.
WARNING
Failure to provide the 1/4 inch clearance
between the supply duct and a combustible
surface for the first 3 feet of duct can result in
fire causing damage, injury or death.
