Materials/Tools List

Additional hardware and miscellaneous supplies are 
needed for installation. These items are field supplied 
and must be sourced before installation. This list also 
includes tools needed for installation.
•  Appropriate safety gear including gloves and safety 

glasses

•  5/16" hex bit with drill driver
•  Phillips head screwdriver
•  Small straight (thermostat) screwdriver
•  Tape measure
•  Leveling device
•  Two (2) tubes of caulk and caulk gun
•  Utility knife
•  Tools for cutting holes in the wall surface (if 

needed)

•  Electrical components and wiring along with 

electrical tools

• Multimeter
•  Wall fasteners for side flanges, bottom mounting 

bracket and top rain flashing.

•  Duct tape and/or other duct sealing materials.

Wall Preparation

1.  Two holes for the supply and return air openings 

must be cut through the wall as shown in Figure 
14 on page 20. Be sure the openings are square 
and level. Follow all clearances including distances 
to combustible materials and all instructions 
provided in this manual.

2.  Review all electrical requirements provided in this 

manual and plan out electrical entrances into the 
building. Also plan electrical conduit routing and 
thermostat placement, if necessary.

3.  Install necessary duct work and prepare the 

openings for unit installation.

4.  Clean the exterior wall where the unit is to be 

installed and make sure it is able to provide a 
smooth, level, debris-free surface. Remove all 
construction debris from the supply, return and 
electrical hole cutting process.

Wall Mount Installation to Wall Surface

1.  Remove packaging from unit and make sure the 

unit is not damaged before installation. A top rain 
flashing is supplied for field use and is mounted to 
the back of the unit for shipping. Remove the rain 
flashing before locating the unit against the wall. 
Top rain flashing is required to avoid water entering 
the area behind the unit that is against the wall. A 
bottom mounting bracket, attached to the skid for 
shipping, is provided for ease of installation but 

is not required. Review all requirements listed on 
unit labels and on serial plate located on the side 
of the unit.

2.  Locate and mark bolt hole locations and bottom 

mounting bracket location. Install bottom 
mounting bracket with field-supplied fasteners to 
wall if it is to be used (optional). Bracket must be 
level and installed in the correct location to help 
support the unit during the installation process 
(see Figure 14). 

3.  Position the wall mount unit close to the wall 

surface where it will be installed. Install rain 
flashing at the top of the unit facing the wall by 
hooking the hem bend into the rear bend of the 
unit top (see Figure 14).

4.  Apply a liberal amount of caulk on left and right 

cabinet side wall mount brackets and back of 
top rain flashing. Place unit back surface flush 
against wall. Unit must be level to ensure proper 
condensate drainage. Optional bottom bracket may 
be used to help support the unit.

5.  Units are secured to the wall by using field-

supplied fasteners along each side of the wall 
mount through the built-in wall mounting brackets. 
It is the responsibility of the installer to select 
the proper fastener to secure the unit to the wall 
based on wall construction and applicable building 
codes. Typical installations may include 5/16" 
fasteners with 7/8" diameter flat washers. Be sure 
unit is securely mounted and all weight-bearing 
fasteners are attached to the weight supporting 
structural members of the wall.

6.  Apply a bead of caulk between the back of the unit 

top and the front surface of the top rain flashing 
(see Figure 14).

7.  Connect unit duct work from the inside of the 

building following all clearances and instructions 
provided. 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 use code approved duct tape or other sealing 
materials to seal the duct work to the unit.

8.  On side-by-side installations, maintain a minimum 

of 20" clearance on both sides to allow access to 
heat strips and to provide proper airflow to the 
outdoor coil. Additional clearance may be required 
to meet local or national codes.
