THESE INSTRUCTIONS

No. II-470

Date May, 2014

Saving energy and creating healthy, comfortable environments

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 qualied 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 airow or

otherwise caused high temperatures to have occurred. DO NOT OPERATE THE HEATER WITH THE ALARM SOUNDING (OR ILLUMINATING).

I. UNCRATING If the air stream strikes any obstruction (the top edge of the doorway, a door opening device, etc.), the effectiveness of the air curtain will be greatly reduced. See Figure 1. B. For optimum performance, the bottom of the air curtain (discharge nozzle) should be no more than 1” above the top of the door opening with the air curtain(s) mounted flush to the wall.
PAGE 3
B. Determine the exact mounting location of the air curtain. NOTE: A minimum of 1” is required above the wall mounting plate to provide clearance for installation and removal of the air curtain. C. Remove the wall mounting plate from the unit to install. The wall mounting plate (included) is designed to fit flush with the top of the Architectural Low Profile 8 Air curtain. Therefore the location of the wall mounting plate will determine the final location of the top of the air curtain. D.

FIGURE 4 - Installing Air Door on Wall Mounting Plate F. Proceed to Section V - Electrical Connections. V. ELECTRICAL CONNECTIONS All electrical wiring and connections MUST be performed by qualified 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. FIGURE 6 - Suspended Mounting tray or it may be located outside of the air curtain.

NOTE: One Intelliswitch serial cable assembly (part # 505SC***INT485-A) is required for every unit that is to be used as a master/slave. “***” denotes length of cable in feet- “008” = 8 feet long. For Master/Slave operation, a serial cable connection must be made between the INTELLISWITCH GEN2 control boards of each unit to be linked. 1. Disconnect power to all the units. 2. Access the wiring tray on top of each unit by removing the screws that hold the cover in place. 3.

VII. OPERATING INSTRUCTIONS Note: If a longer cable is required than was supplied, it can be ordered from the factory or made by using standard flat telephone cable, phone jack connectors and the proper crimping tool. 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.

FIGURE 10- Intake Grill Removal IX. SERVICE CAUTION: ELECTRIC SHOCK HAZARD Disconnect power whenever servicing unit. More than one disconnect may be required to de-energize unit. Any service performed on the Architectural Low Profile 8 air door MUST be done by qualified personnel. 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.

NOTE: GROUND RING TERMINAL MUST BE SITUATED OR BEND SUCH THAT IT DOES NOT TOUCH ANY TRACES ON THE CONTROL BOARD 11. Continue installing the new control board into the unit by carefully sliding the two tabs at the top of the control board into the two corresponding slots in the unit frame. Attach with new plastic push-rivets provided. Note: when the tabs of the board hit the unit frame tip the board up and angle the tabs into the slots. 12. Reconnect all wires to the control board. 13.

grille up and then away from the unit. Remove the bottom access panel by removing the Phillips head screws on the bottom of the unit. The speed sensor is held in with two 13 mm hex nuts and a star washer. 6. Use the 13 mm nuts to position the tip of the sensor a maximum of 1/16” (2 mm) away from the rotating trigger located on the motor shaft. When the unit is energized, the LED on the back of the sensor will illuminate when the trigger passes if the correct distance has been set.

How to operate your Architectural Low Profile 8 Air Curtain that comes with a factory installed digital programmable controller called the Intelliswitch™ INTELLISWITCH™ QUICK START OPERATION www.intelli-how2.com When power is turned on to the Air Curtain, all of the lights on the display will light briefly while the Intelliswitch™ starts up. After startup the clock will then display. The Intelliswich is now ready to set. NOTE: To adjust the clock, refer to section 4.5 Appendix A.
PAGE 11
Modes of Operation continued: The following modes can be customized see “Programming the Intelliswitch” for more info. “PluS” COMFORT PLUS “Pro1” PROGRAM 1 “Pro2” PROGRAM 2 For use on heated units only, requires a door switch. When the temperature drops below the thermostat set point and the door is closed, the unit will activate on a low speed and provide supplemental heating to the space. The unit will change to normal speed when the door is open.
