WARNING: TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:
A. Read all instructions before installing or using this air curtain.
B. Use this unit only in the manner intended by the manufacturer and described in this manual. Any other use not recommended by the
manufacturer may cause re, electric shock, or injury to persons. If you have any questions, contact the manufacturer.
C. Before servicing or cleaning unit, switch power o at service panel and lock the service disconnecting means to prevent power from
being switched on accidentally. When the service disconnecting means cannot be locked, securely fasten a prominent warning device,
such as a tag, to the service panel.
D. Installation work and electrical wiring must be done by qualied person(s) in accordance with all applicable national and local codes
having jurisdiction, including re-rated construction. See page 4, ELECTRICAL CONNECTIONS (NEC Code ANSI/NFPA No. 70).
E. When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.
F. To reduce the risk of re, do not store or use gasoline or other ammable vapors and liquids in the vicinity of the air curtain.
G. This air curtain is hot when in use. To avoid burns, do not let bare skin touch hot surfaces. Keep combustible materials, such as furniture,
pillows, bedding, papers, clothes, etc. and curtains at least 1 inch from the top, back, front, sides and at least 6 feet from the discharge of
the air curtain.
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. Immediately verify that the electrical rating nameplate located on
the cover matches the electrical power supply available. Retain
the shipping carton(s) until the unit(s) is 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.
mounting method and; as a general rule, use the mounting
conguration that positions the air door as close to the top
of the doorway as possible without interfering with door
operation.
B. The IDC12/IDC14 Series air door 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 the air stream
free of obstructions. If the air door cannot be installed ush
with the wall, be sure to seal the gap between the wall and
the back of the air door along the entire length of the unit to
prevent airow through this void.
II. MOUNTING INSTRUCTIONS
(General Notes for All Mounting Congurations)
INDOOR MOUNTING - Environmental/Insect/Dust Control
OUTDOOR MOUNTING (Unheated Only) - Insect/Dust Control
A. Berner IDC12/IDC14 air doors are designed to be mounted
by their end anges without the need for intermediate
support. Each end ange contains (8) total ½” holes located
on all (4) sides to facilitate mounting exibility and the easy
addition of mounting accessories. Units may be attached to
the wall directly, suspended from overhead, or supported
by brackets. The style of door will determine the best

C. 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.
D. Before mounting the air door, check the supporting
structure to verify that it has sucient 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
Tables 1 & 2.

E. The air door is weatherproof. Therefore, no special covering
is required when outdoor mounting unheated, steam, or hot
water units.
NOTE: Electric heated units are to be installed indoors
only.
F. IMPORTANT: A minimum of 4” (8” preferred) clearance
is recommended above the top of the air door for the
installation and removal of the screen or to gain access to
junction boxes.
G. 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 eectiveness of the unit will be greatly
reduced. See Drawing 1.
H. 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. See Drawing 2.
I. 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.
2. Have a minimum clearance of at least 6’ between the
bottom of the unit and the oor.
3. Be installed indoors only.

III. WALL MOUNTING
A. Wall mounting works well with standard hinged doors or
sliding doors.
B. The IDC12/IDC14 Series end plates are equipped with ½”
holes for wall mounting. The unit may be attached to the wall
using, at minimum, ³/” bolts through the holes on the back
of the end plate. See Figure 1. Or, the unit may be attached
using an optional wall mounting bracket or a combination
of extension and wall mounting brackets (available from
Berner) attached to the holes on the top of the end plate
and the wall. See Figure 2.

J. Proceed to one of the following sections, depending
on application and door type:

Section IV: Suspended Mounting
Section V: Vertical Mounting
