H. Extreme caution is necessary when any air curtain is used by or near children or invalids, and whenever the heater is left operating unattended.
I. Do not operate any air curtain after it malfunctions. Disconnect power at the service panel and have the air curtain inspected by a reputable
electrician before reusing.
J. To disconnect the air curtain, turn controls to "o", and turn o power to the air curtain circuit at main disconnect panel.
K. Do not insert or allow foreign objects to enter any ventilation or discharge opening as this may cause an electric shock or re, or damage
the air curtain.
L. To prevent a possible re, do not block the air intake or discharge of the air curtain in any manner.
M. The air curtain has hot and arcing or sparking parts inside. Do not use it in areas where gasoline, paint, or ammable vapors or liquids are
used or stored.
N. This heater may include an audible or visual alarm to warn that parts of the heater are getting excessively hot. If the alarm sounds (or illuminates),
immediately turn the heater o and inspect for any objects on or adjacent to the heater that may have blocked the airow or otherwise caused
high temperatures to have occurred. DO NOT OPERATE THE HEATER WITH THE ALARM SOUNDING (OR ILLUMINATING).

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
protective 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
accessories (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 discarding.
II. MOUNTING INSTRUCTIONS (General)
INDOOR MOUNTING - Environmental/Insect Dust Control
OUTDOOR MOUNTING (Unheated Only) - Insect/Dust Control
The SHC07/CHC10 Air Curtain is designed to be an eective 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, ush 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 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 unit, check the supporting structure to verify that it
has sucient load-carrying capacity to support the weight of the unit(s).

FIGURE 1 - Air Stream
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 curtain is weatherproof, therefore no special covering is
required for outdoor mounting.
IMPORTANT: A minimum of 4” is recommended above the top of the
Air curtain for the installation and removal of the cover housing.
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 eectiveness 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 ush to the wall. If the unit must be mounted
higher, it must be spaced out from the wall ³/₈” for every inch the
unit 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 unit.
See Figure 2.

C. Electric heated units shall:
1. Have a minimum clearance of at least 4” between the sides and
top of the unit and any combustible material.
2. Have a minimum clearance of at least 6’ between the bottom of
the unit and the oor.
3. Be installed indoors only.
D. Proceed to either Section III - WALL MOUNTING, or Section IV
SUSPENDED 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.

FIGURE 3 - Positioning of Mounting Plate
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.
D. Anchor the wall mounting plate over the door opening with
the mounting tabs pointing upwards.
E. Raise the unit over the door (air nozzle facing down) and onto
the mounting plate. Tilt the unit upward, matching the holes
in the frame with the tabs on the mounting plate.
See FIGURE 4.
F. Lower the unit into place allowing it to rest on the mounting
plate. The unit ange should rest above the mounting plate
ange.
G. After the unit is securely seated to the mounting plate, install
the locking screws along the bottom ange. See FIGURE 4.
H. Proceed to Section V-ELECTRICAL CONNECTIONS
IV. SUSPENDED MOUNTING
(Ceiling Suspension)
A. When the unit is top mounted, the wall mounting plate is
designed to store on the back of unit for future use.

C. Determine the exact mounting location of the air curtain.
D. The top of the unit is provided with an electrical knockout
for power connection. Remove the wiring tray compartment
cover. Remove the knockout and attach necessary electrical
hardware. Save the wiring diagram found inside of wiring
tray.
E. Attach #10-24 threaded rods, or other suitable hardware to
the top mounted threaded inserts.
F. Proceed to Section V-ELECTRICAL CONNECTIONS
