INSTALLATION INSTRUCTIONS
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.
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, 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 and W60. 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.
