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.

  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.

  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, attached 
to skid for shipping, 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 for model series 
W30, W36, W42, W48, W60 and W70.  However, 
it is generally recommended that a 1-inch clearance 
is used for ease of installation and maintaining the 
required clearance to combustible material.  See 
Figure 3 for details on opening sizes.

  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, attached to front - right of 

supply flange for shipping, under back bend of top.

 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.
