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 conguration 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
eective 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 airow through this void.

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 eectiveness 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.
DRAWING 2
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.

FIGURE 4 - With Extension Brackets
IV. SUSPENDED MOUNTING
A. Suspended mounting works well with the majority of door
types commonly found in an industrial setting, such as roll-
up doors, “high rise” track doors, “low-rise” turn back doors,
and “high-rise” turn back doors.
B. The IDC12/IDC14 Series end plates are equipped with ½”
holes for suspended mounting. The unit may be suspended using a minimum ³/” suspension rod (Figure 3), or using
/” suspension rods and extension brackets (available from
³ Berner). See Figure 4.
C. Electrical Connections - Proceed to Section VII.
V. VERTICAL MOUNTING
A. Vertical mounting works well when the opening is taller
than it is wide, or when the door type prevents a typical “over-door” mounting position.
B. Optional Floor Mounting Brackets (available from Berner)
bolt to the unit end plate, and provide a rigid base to attach the unit to the oor. Two Brackets are required.
C. To vertically mount a IDC12/IDC14 Series unit using optional
Floor Mounting Brackets, bolt brackets on the inside of the end plate with (4) ½ - 13 bolts as shown in Figure 5.
B. Tandem Mounting Brackets connect the end plates of the
units to be joined. Two brackets are required. Ideally, the units are joined together before the lower unit is bolted to the oor.
C. Using (4) ½ - 13 x 1” bolts, attach the Tandem Mounting
Brackets to the inside of one of the unit’s end plates as shown in Figure 8.
D. Slide the end plate of the next unit over the brackets
installed in Step C and attach using (4) additional ½” bolts as shown in Figure 9.
E. Assemble Floor Mounting Brackets to lower unit and attach
to oor per steps C and D of Section V.
F. Electrical Connections - Proceed to Section VII.
VII. ELECTRICAL CONNECTIONS
All electrical wiring and connections MUST be performed by qualied personnel in accordance with the National Electrical Code ANSI/NFPA No. 70 (latest edition) or, in Canada, the Canadian Electrical Code, Part 1-C.S.A. Standard C22.1, and local codes and regulations.
D. Position the unit vertically in its intended position and
anchor it to the oor with a minimum ³/” fastener.
See Figure 6.
E. To improve the stability of the installation, it is required
that the top of the unit be attached to the wall. A common approach is to attach a minimum length of ³/” threaded rod through one of the open mounting holes in the top end plate and ax the other end of the rod to the wall.
See Figure 7. F. Electrical Connections - Proceed to Section VII.
VI. TANDEM MOUNTING BRACKETS
(For Vertical Mount Installation)
A. Optional Tandem Mounting Brackets (available from Berner)
are used to join two air curtains together in a vertical application when the door height exceeds 16’.

A. Check the rating nameplate on the top of the unit for supply
voltage and current requirements. A separate line voltage supply with a suitable branch circuit protection device should be run directly from the main electrical panel to the unit. A disconnect switch for each branch circuit is a required part of this installation.
B. All eld wiring must be copper with a minimum insulation
of 60° C within approved conduit. If any of the wire supplied with the unit must be replaced, it must be replaced with copper wiring with a minimum insulation of 90° C.
C. Remove the Junction Box cover.
D. Connect the power supply to the unit. Connect all supply
and control circuit wires according to wiring diagram provided.
E. Re-install the Junction Box cover.
NOTE: For electric heated units provided with optional
remote thermostat: Mount and wire the thermostat according to instructions and wiring diagram.
VIII. MECHANICAL CONNECTIONS
A. ELECTRIC HEATED MODELS
The heater circuit may be controlled by a remote thermostat
or manually through the switch located on the discharge side of the unit. Overheating protection is provided by auto reset thermal cutouts built into the heater coil assembly (see
the wiring diagram).
B. STEAM OR HOT WATER HEATED MODELS
Piping should be done in accordance with local codes,
regulations and standard practices. Connect the building system supply and return to the MNPT nipples on the heating coil. See Figure 10.

IX. OPERATING INSTRUCTIONS
A. GENERAL OPERATION
Air curtain operation may be divided into four areas: control package, fan activation, fan speed selection, and heat activation. The air curtain must be properly installed before it is used.
1. Control packages control the unit’s sequence of operation. Unit modes/control packages are built into the unit and may not be changed in the eld.. Refer to your wiring diagram for specics about activation connections and sequence of operation. a. Basic Control Package – The unit is activated by a door switch. The door switch may be line voltage or low voltage (24V). b. Deluxe Control Package – The unit is activated by a door switch, but has a factory installed time delay allowing the unit to keep running for a period of time after the door closes. c. Comfort Plus Control Package – Available only on heated units, the unit is activated by the door switch OR by the thermostat to provide supplemental heating.
2. Unheated units will have the fans activated by a door switch or sensor. The unit may be single speed and require no fan speed selector (On/O ), or may have multiple fan speeds which require either a unit or remote mounted switch (O, High, Med, Low).
3. Heated units will have fans activated by a door switch or sensor, but may also be activated by the thermostat in Comfort Plus Mode. The unit may be single speed and controlled by either a unit or remote mounted switch (Fan, O, Heat), or may have multiple fan speeds which can be set by either a unit or remote mounted switch (Low, Med, High, O, Low heat, Med Heat, High Heat).
4. Heat activation is controlled by either a unit or remote mounted thermostat, and a unit or remote mounted switch.
B. AIR STREAM ADJUSTMENT
1. With the air curtain operating and the door in its full open position, check to see that nothing is obstructing the airow at the discharge nozzle vanes.
2. Find the air stream split location. Hold a handkerchief by its corners, approximately 12” above the oor. Gently move the handkerchief back and forth in the doorway. Make sure the air is being directed to both the inside and the outside. See Figure 11. The split location is indicated where the handkerchief is vertical with minimal or no uttering.
3. The split location should be approximately 3” outside the doorway. If necessary adjust the discharge nozzle vanes by de-energizing the unit, loosening the nozzle vane locking screws and adjusting vanes.
X. MAINTENANCE AND CLEANING
CAUTION: ELECTRIC SHOCK HAZARD: Disconnect power when servicing unit. More than one disconnect may be required to de-energize unit.
Keep your air curtain operating at peak eciency by cleaning the blower wheels, motor(s) and intake grille. Build up of dust on the blower wheels can cause vibration, noise and excessive wear on the motor bearings. The frequency of cleaning will depend on the environment where the unit is operating.
Dirty, dusty or greasy environments could require a cleaning schedule of once every two months. If the environment is not that dirty, the unit(s) should be scheduled for cleaning a minimum of once every (6) months. To access the interior of the unit: A. Disconnect the power to the unit and remove the intake
grille by removing the screws on the top and bottom of the screen.
B. Remove the bottom access panel by removing the phillips
head screws on the bottom of the unit.
C. Vacuum and scrape (if necessary) to remove the build up of
dirt and debris. The motor(s) are permanently lubricated and require no additional lubrication. Reinstall the cover
and intake grille.
D. Switch the power on after cleaning. CAUTION: STAND
CLEAR OF THE UNIT OR WEAR SAFETY GOGGLES AS LOOSE DEBRIS MAY BE PRESENT AND MAY EXIT THE NOZZLE.
FIGURE 11 - Air Stream Split
XI. SERVICE
CAUTION: ELECTRIC SHOCK HAZARD: Disconnect power when servicing unit. More than one disconnect may be required to de-energize unit.
Any service performed on the IDC12/IDC14 Series air curtain MUST be done by qualied personnal
Berner air doors require very little servicing. All parts are easily accessible for periodic inspection and maintenance. Units should be cleaned at least twice a year. Your particular application (the amount of dirt and dust in the air) and location of the unit(s) will determine how often your unit(s) will need to be cleaned and serviced. All motors have permanently lubricated, sealed, sleeve or ball bearings and require no maintenance.
