INSTALLATION INSTRUCTIONS
WALL MOUNTING INFORMATION
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. 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
unit being installed.
4. The unit is suitable for 0 inch clearance from the unit,
and from the supply and return air ducts.
MOUNTING THE UNIT
1. Two holes for the supply and return air openings must
be cut through the wall as shown in Figure 3.
2. Locate and mark lag bolt locations and bottom
mounting bracket location, if desired. See Figure 3.
3. Mount bottom mounting bracket, if used.
4. Hook top rain flashing under back bend of top. Top
rain flashing is shipped secured to the right side of the
back.
5. Position unit in opening and secure with 5/16 lag bolts.
Use 5/16” flat washers on the lag bolts.
6. Secure rain flashing to wall and caulk across entire
length of top. See Figure 3.
7. 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.
8. On side by side installations, maintain a minimum of 20
inches clearance on right side of unit to allow access to
control panel and heaters, and to allow proper airflow to
the outdoor coil. Additional clearance may be required
to meet local or national codes.
