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. 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 Figures 3A & 3B.
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 Figures 3A & 3B.
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.
PLACEMENT
1. 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.
2. Care should be taken to ensure that the recirculation
and obstruction of condenser discharge air does not
occur. Recirculation of condenser discharge air can
be from either a single unit or multiple units. Any
object such as shrubbery, a building or a large object
can cause obstructions to the condenser discharge
air. Recirculation or reduced airflow caused by
obstructions will result in reduced capacity, possible
unit pressure safety lockouts and reduced unit
service life.
Units with a blow through condenser, such as the
S**H 10 EER units, it is recommended that a
minimum distance of 15 feet between the front of
the unit and any barrier or 20 feet between the fronts
of two opposing (facing) units.
Units with a draw through condenser, such as the
W**H 10 EER units, it is recommended that a
minimum distance of 10 feet between the front of
the unit and any barrier or opposing (facing) unit.
