II. MOUNTING INSTRUCTIONS (General)
INDOOR MOUNTING ONLY -
The Architectural Elite 8 Air Curtain is designed to be an
effective barrier against cold drafts in the winter and hot air in
the summer, flying insects and airborne contaminants.
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 1" is required above the top of
the air curtain for the installation and removal of the
cover housing.
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. For optimum protection, any
void between the air curtain and the wall should be
sealed along the full length of the air curtain.
NOTE: for wall mounting, the wall mounting plate
thickness provides a natural 1-3/8" space which allows
for mounting up to 4" above the opening.
C.
Do not block (obstruct) the air intake grill. Insufficient
airflow can cause the unit to overheat.
D.
Electric heated air curtain(s) shall:
1. Have a minimum clearance of at least 4" between
the sides and 8" from the top for electric heated units.
Have a minimum clearance of at least 6' between the
bottom of the air curtain and the floor.
2. Be installed Indoors Only.
E.
Proceed to either Section III - WALL MOUNTING or
