II. MOUNTING INSTRUCTIONS (General)
INDOOR MOUNTING - Environmental/ Insect/ Dust Control
OUTDOOR MOUNTING (Unheated Only) - Insect/Dust Control
The Commercial High Performance 10 & the Sanitation
Certified High Performance 7 Air Curtains are 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 or Table 2.
IMPORTANT: A minimum of 4" is required above the top of the
air curtain for the installation and removal of the inlet
screen and access to electrical compartment.
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 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 top of the air curtain and any
combustible material.
2.
Have a minimum clearance of at least 6' between
the bottom of the air curtain and the floor.
3.
Be installed Indoors Only.
