Fasten flanges to

top using (8) screws

Top outlet flange is screwed to the back of the unit 
upon delivery.  Flange must be installed on to the top of 
the unit before mounting.  See Figure 3 for details. 

  1. These units are secured by wall mounting brackets 

which secure the unit to the outside wall surface at 
both sides.

  2. The unit itself is suitable for 0 inch clearance.  If 

a combustible wall use a minimum of 30" x 10" 
supply opening dimensions for sizing.  However, it 
is generally recommended that a 1-inch clearance 
be used for ease of installation.  The supply air 
opening would then be 32" x 12".  See Figures 4 
and 5 for details.

  3. Hook top rain flashing under back bend of top.  Top 

rain flashing is shipped with unit attached to back of 
unit on the right side.

 4.  Position unit in opening and secure with 5/16 lag 

bolts; use 3/4 inch diameter flat washers on the lag 
bolts.

  5. Secure rain flashing to wall and caulk across entire 

length of top.  See Figure 4.

  6. 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.

  7. 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.
