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 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 30-1/2” x 10-1/2” 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.

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.

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 left 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.
