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 installing unit.
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
bracket location, if desired. See Figure 3.
INSTALLATION INSTRUCTIONS
3. Mount bottom mounting bracket, if used.
4. Hook top rain flashing under back bend of top. Top
rain flashing is shipped attached to the back of the
unit on the right side.
5. Position unit in opening and secure with 5/16 lag
bolts; use 7/8" diameter 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.
Additional clearance may be required to meet local or
national codes.
8. On side-by-side installations, maintain a minimum of
20 inches clearance on left side to allow access to
heat strips and control panel and to allow proper
airflow to the outdoor coil.
