I. UNCRATING
Carefully examine the carton(s) for damage before opening. If the carton
is damaged, immediately notify shipping company. If the unit(s) were
shipped on wooden skids, remove protective wood and banding straps
securing the carton(s) to the skid. Open the carton(s) and remove all pro-
tective packaging. Remove the plastic cover housing by lifting vertically.
Remove and discard four (4) nuts and washers holding the motor/blower
section to the bottom of the carton. Remove motor/blower section from
the carton.
CAUTION: ONLY LIFT THE UNIT BY GRASPING INLET RINGS ON THE
BLOWER HOUSING WITHOUT TOUCHING BLOWER WHEELS.
Immediately verify that the electrical rating nameplate located on the
cover matches electrical power supply available. Retain the shipping
carton(s) until the unit(s) are installed and properly operating.
ACCESSORIES: If the unit(s) were ordered with optional electrical acces-
sories (door switch, control panel, etc.), the accessories may be found in
the carton containing the unit or in a separate carton(s) accompanying
the unit(s). Check all of the cartons/skids for accessories before discard-
ing.
II. MOUNTING INSTRUCTIONS
The E-Zone/K-Zone air door 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 protec-
tion, 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.
FIGURE 1 - Air Stream
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.
(General)
WARNING: Use caution when mounting the air curtain to
ensure adequate clearance is provided for variable speed
control knob located on unit bottom. Failure to do so will
result in permanent damage to the controller.
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 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 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
/

void between the air door and the wall should be sealed along
the full length of the unit. See FIGURE 2
C. Proceed to Section III-WALL MOUNTING
III. WALL MOUNTING
A. Determine the location on the wall above the opening where
the air curtain will be mounted. This location should center
the unit over the opening and provide suitable mounting
support. It is recommended to use at least four locations that
correspond to the outer corners of the wall mounting plate.
See FIGURE 3.
B.
Prepare the wall as necessary for the wall mounting plate
anchors (by others).
C. Drill holes in the wall mounting plate to correspond to the
locations on the wall.
