II. MOUNTING INSTRUCTIONS
(General)
INDOOR MOUNTING - Environmental/Insect/Dust Control
OUTDOOR MOUNTING (Unheated Only)- Insect/Dust Control
Zephyr/Maxair air door is designed to be an effective barrier
against cold drafts in the winter and hot air in the summer. To
achieve optimum protection, the unit 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
air stream free of obstructions.
The air door 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 unit, check the supporting structure to verify
that it has sufficient load-carrying capacity to support the weight
of the unit(s). The mounting hardware (supplied by others) should
be capable of supporting a minimum of three (3) times the weight
of the unit. See Table 1.
NOTE: The air door is weatherproof, therefore no special cover-
ing is required for outdoor mounting.
IMPORTANT: A minimum of 1" is recommended above the top
of the air door for the installation and removal of the cover hous-
ing.
A. When determining the mounting location for the unit(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 effective-
ness of the unit will be greatly reduced. See Figure 1
B. For optimum performance, the bottom of the unit (discharge
nozzle) should be no more than 1" above the top of the door
opening with the unit mounted flush to the wall. If the unit must
be mounted higher, it must be spaced out from the wall
every inch the unit is above the door opening. For optimum
protection, any void between the air door and the wall should be
sealed along the full length of the unit.
C. Electric heated units shall:
1. Have a minimum clearance of at least 1" between the sides
and top of the unit and any combustible material.

tom of the unit and the floor.
3. Be installed indoors only.

WALL MOUNTING
A. The ZPR/MAX Series Air Door is equipped with two ¼" threaded
inserts on the back of each unit (two per module on units 84" and
over). Insert and tighten the shoulder bolts (provided) into these
threaded inserts. A minimum of two shoulder bolts are required,
on units comprised of modules use the outer threaded inserts
and a minimum of one of the inner threaded inserts.
B. Determine the exact mounting location of the air door unit.
NOTE: A minimum of ¾" is required above the wall mounting
plate to provide clearance for installation and removal of the
unit.
C. The wall mounting plate (included) is designed to fit flush with
the top of the ZPR/MAX Series Air Door. Therefore the location
of the wall mounting plate will determine the final location of the
top of the Air Door.
D. Position the center of the wall mounting plate over the center of
the door opening with the larger opening of the key hole slots
facing up. For optimum performance, the bottom of the mount-
ing plate should be no more than 2" or less than 1" above the
top of the door opening. The wall mounting plate thickness pro-
vides a natural ¾" space which allows for mounting it up to 4"
above the opening. See Figure 2
