I. UNCRATING
Carefully examine the carton(s) for damage. If the carton
is damaged, immediately notify the shipping company. Do
not delay in filing claim. If the air door(s) were shipped on
wooden skids, remove protective wood and banding straps se-
curing the carton(s) to the skid. Open the carton(s) and remove
all protective packaging. Immediately verify that the electrical
rating nameplate located on the cover matches electrical power
supply available. Retain the shipping carton(s) until the air
door(s) are installed and properly operating.
ACCESSORIES: If the air door(s) were ordered with optional
electrical accessories, the accessories will be found in the carton
containing the air door or in a separate carton(s) accompany-
ing the air door(s). Check all of the cartons/skids for accessories
before discarding.
II. MOUNTING INSTRUCTIONS
(General)
INDOOR MOUNTING ONLY - Environmental/Insect/Dust Control
The MaxAir /Zephyr Air Door are designed to be an effective barrier
against cold drafts in the winter and hot air in the summer. To achieve
optimum protection, the air door should be mounted on the inside of
the building, flush to the wall and as close to the top of the door open-
ing as possible. To ensure peak performance, keep the air stream free
of obstructions.
The air door will not perform properly if negative air pressure ex-
ists 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 door, check the supporting structure to verify
that it has sufficient load-carrying capacity to support the weight of
the air door(s). The mounting hardware (supplied by others) should be
capable of supporting a minimum of three (3) times the weight of the
air door.
See Table 1.
IMPORTANT: A minimum of 1" is required above the top of the
air door for the installation and removal of the cover housing.
A. When determining the mounting location for the
air door(s), make sure that nothing interferes with the
curtain of air developed when the discharge vanes
are directed from 0º to 20º 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 door will be greatly reduced.
See Figure 1.
B.
For optimum performance, the bottom of the air door
(discharge nozzle) should be no more than 1" above
the top of the door opening with the air door(s)
mounted flush to the wall. If the air door must be
mounted higher, it must be spaced out from the
wall ³ / ₈ " for every inch the air door is above the door
opening. See Figure 3. For optimum protection, any void
between the air door and the wall should be sealed along
the full length of the air door.
C. Electric heated air door(s) shall:
1.
Have a minimum clearance of at least 1"
between the sides and top of the air door and
any combustible material.
2.
Have a minimum clearance of at least 6'
between the bottom of the air door and the floor.
3.
Be installed Indoors Only.
D. Proceed to either Section III - WALL MOUNTING
or Section IV - SUSPENDED MOUNTING
III. WALL MOUNTING
A. The MaxAir/Zephyr Air Door is equipped with two
¼" threaded inserts on the back of each air door (two
per module on air doors 84" and over). Insert and
tighten the shoulder bolts (provided in bag taped to the
wall plate) into these threaded inserts. A minimum of two
shoulder bolts are required; on air doors comprised of
modules, use the outer threaded inserts and a minimum of
one of the inner threaded inserts.
