B.
Determine the exact mounting location of the air door.
NOTE: A minimum of 1" is required above
the wall mounting plate to provide clearance
for installation and removal of the air door.
C. Remove the wall mounting plate from the unit to install.
The wall mounting plate (included) is designed to fit flush
with the top of the MaxAir/Zephyr Air Door. Therefore the
location of the wall mounting plate will determine the final
location of the top of the air door.
D. For Standard Flush Wall Mounting, position the center of
the wall mounting plate over the center of the door open
ing with the larger opening of the key hole slots facing up.
The wall mounting plate thickness provides a natural ¾"
space which allows for mounting it up to 4" above the
opening. For optimum performance, the bottom of the
mounting plate should be no more than 2" or less than
1" above the top of the door opening.
See Figure 2.
High Wall Mounting must be used if the wall mounting
plate must be mounted higher than 4" above the
door opening: the mounting plate must be spaced out
from the wall ³ / ₈ " for every additional inch (over 4") that
the air door is above the door opening (clearance height).
See Figure 3. For optimum protection, do not exceed the
recommended maximum mounting height of 8' above
the finished floor. Any void between the mounting plate
and the wall should be sealed along the full length of the
mounting plate.
E.
Determine which of the four holes provided in each of
the steel brackets of the wall mounting plate are located
where suitable support is available for the air door.
A minimum of one inside hole and one outside hole from
FIGURE 2 - Standard Flush Wall Mounting
each bracket must be used for proper support.
Drill out the aluminum backing of the holes chosen
with a ¼" drill bit. If the provided holes on the
mounting plate are not located where suitable support
is available, drill new holes in the space provided on
the steel mounting brackets.
F.
Mark the wall in the centers of the ¼" holes drilled on the
mounting plate.
G. Attach the mounting plate to the wall (hardware by others).
H. The top of the air door is provided with two knockouts on
each side allowing for a left or right hand power
connection. Remove the wiring tray cover; on air doors

that are comprised of modules, remove the wiring tray

attach the necessary electrical hardware. Save the wiring
diagram found inside of the wiring tray. See Figure 7.
I.
There are two sets of keyhole slots on the wall mounting
plate. In low overhead installations, the air door may be
staged in the lower keyholes to provide clearance for
electrical wiring and then moved to the higher key holes
after completion. Raise the air door with the discharge
opening facing down toward the floor. While
holding the air door level, slide the heads of the
shoulder bolts into the larger hole of the keyhole
slots of the mounting plate. Lower the air door
into place, keeping both ends level, allowing it to rest flush
with the mounting plate. See Figure 4.
J.
After attaching the air door to the mounting plate, ensure
that the air door is seated and flush with the mounting
plate on all four sides.
K. Proceed to Section V - Electrical Connections.
IV. SUSPENDED MOUNTING
(Ceiling Suspension)
A. When the air door is top mounted, the wall mounting plate
is designed to store on the back of the air door for future
use. See Figure 5.
B.
Four (4) factory installed ¼" threaded inserts are located
on the top of the air door for top suspension mounting; on
air doors comprised of modules use the
outer threaded inserts.
To eliminate the slight deflection of longer air doors, the
inner threaded inserts may also be used. See Figure 6.
C. Determine the exact mounting location of the air door.
D. The top of the air door is provided with two knock-
outs on each side allowing for a left or right hand
power connection. Remove the wiring tray cover;
on air doors that are comprised of modules, remove
the wiring tray cover that is located closest to the
electrical rating nameplate. Remove the required
knockouts and attach the necessary electrical hardware.
Save the wiring diagram found inside of the wiring tray.
See Figure 7.
E.
Attach ¼" threaded rods or other suitable hardware to the
top mounted threaded inserts.
