B.
Determine the exact mounting location of the air curtain.
NOTE: A minimum of 1" is required above
the wall mounting plate to provide clearance
for installation and removal of the air curtain.
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 Architectural Low Profile 8 Air curtain.
Therefore the location of the wall mounting plate will
determine the final location of the top of the air curtain.
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 curtain 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 mount
ing 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 curtain.
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 curtain is provided with two knockouts
on each side allowing for a left or right hand power
connection. Remove the wiring tray cover; on air curtains

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 curtain 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 curtain with the discharge
opening facing down toward the floor. While
holding the air curtain level, slide the heads of the
shoulder bolts into the larger hole of the keyhole
slots of the mounting plate. Lower the air curtain
into place, keeping both ends level, allowing it to rest flush
with the mounting plate. See Figure 4.
J.
After attaching the air curtain to the mounting plate,
ensure that the air curtain 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 curtain is top mounted, the wall mounting
plate is designed to store on the back of the air curtain for
future use. See Figure 5.
B.
Four (4) factory installed ¼" threaded inserts are located
on the top of the air curtain for top suspension mounting;
on air curtains comprised of modules use the
outer threaded inserts.
To eliminate the slight deflection of longer air curtains, the
inner threaded inserts may also be used. See Figure 6.
C. Determine the exact mounting location of the air curtain.
D. The top of the air curtain 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 curtains 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.
Proceed to Section V - Electrical Connections.
