ページを印刷するII. MOUNTING INSTRUCTIONS (General)
INDOOR MOUNTING ONLY -
To achieve optimum protection, the air curtain should be
mounted on the inside of the building, flush to the wall and
as close to the top of the door opening as possible. To ensure
peak performance, keep the air stream free of obstructions.
The air curtain will not perform properly if negative air
pressure exists in the building. Under these conditions,
a means for makeup air to the building must be provided
so that the air pressure on both sides of the opening is in
balance.
Before mounting the air curtain, check the supporting structure
to verify that it has sufficient load-carrying capacity to support
the weight of the air curtain(s). The mounting hardware
(supplied by others) should be capable of supporting a
minimum of three (3) times the weight of the air curtain.
See Table 1.
IMPORTANT: A minimum of 4" is required above the top rear
corner of the air curtain for the installation and removal of the
inlet screen, and to ensure proper airflow.
A.
When determining the mounting location for the air
curtain(s), make sure that nothing interferes with the
curtain of air developed when the discharge vanes
are directed from 0° to 20° toward the door opening. If
the air stream strikes any obstruction (the top edge of the
doorway, a door opening device, etc.), the effectiveness
of the air curtain will be greatly reduced. See Figure 2.
B.
For optimum performance, the bottom of the air curtain
(discharge nozzle) should be no more than 1" above
the top of the door opening with the air curtain(s)
mounted flush to the wall. If the air curtain must be
mounted higher, it must be spaced out from the
wall 3/8" for every inch the air curtain is above the door
opening. See Figure 3. For optimum protection, any void
between the air curtain and the wall should be sealed
along the full length of the air curtain.
C.
Do not block (obstruct) the air intake screen. Insufficient
airflow can cause the unit to overheat.
D.
The air curtain(s) shall:
1.
Have a minimum clearance of at least 4"
from the sides and 4" from the top.
2.
Have a minimum clearance of at least 6'
between the bottom of the air curtain and the floor.
3.
Be installed Indoors Only.
Proceed to either Section III - WALL MOUNTING or

Section IV - SUSPENDED MOUNTING
III. WALL MOUNTING
PREPARATION
A.
1.
Locate the wall mounting plates, in the carton that
contained the unit. See Figure 4. For units over 72",
there are more than two wall mounting plates.
2.
Use ¼"-20 bolts to attach the wall mounting plates
to the back of the air curtain.
