INSTALLATION INSTRUCTIONS

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.

WALL MOUNTING INFORMATION

1. Two holes for the supply and return air openings

must be cut through the wall as shown in Figure 3.

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.

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". See Figures 3 and 4 for details.

3. Locate and mark lag bolt locations and bottom

mounting bracket location. See Figure 3.

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. See Figure 3.

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.
