Description

Leading Edge air curtains produce a wall of continuously flowing air that acts as a thermal barrier against outside air and flying insects. These air curtains maintain interior conditioned temperature and prevent heated or cooled air from escaping through open doorways. They reduce humidity and loss of cold air when used over freezer and cooler doors. High traffic area doors can be left open, eliminating wear and nuisance of opening and closing automatic and manual doors. Used over service entrances, receiving doors, customer entrances, access

doors, etc. ... air curtains provide protection against

insects, dust, odor, fumes and other contaminant’s.

WARNING - TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS OBSERVE THE FOLLOWING:

1. Use this unit only in the manner intended by the manufacturer. If you have questions contact the manufacturer.

2. Before servicing or cleaning unit, switch power off at service panel and lock service panel to prevent power from being switched on accidentally.

3. Installation work and electrical wiring must be done by qualified persons in accordance with all applicable codes and standards, including fire rated construction.

4. When cutting or drilling into wall or ceiling, do not damage electrical wiring or other hidden utilities.

5. Make certain that the power source conforms to the electrical requirements of the unit. Disconnect power before installing or servicing. If the power disconnect is out of sight, lock it in the open position and tag it to prevent unexpected application of power. Failure to do so could result in fatal electrical shock.

WARNING: DO NOT DEPEND UPON A THERMOSTAT OR OTHER SWITCH AS THE SOLE MEANS OF DISCONNECTING POWER WHEN INSTALLING OR SERVICING THE UNIT. ALWAYS DISCONNECT POWER AT THE MAIN CIRCUIT BREAKER AS DESCRIBED ABOVE. FAILURE TO DO SO COULD RESULT IN FATAL ELECTRIC SHOCK.

6. To remove motor/blower assembly, lift from rear of motor housing to prevent damage and misalignment to shaft and blower wheels.

NOTE: Unit is shipped with styrofoam motor support block which must be discarded at this time.

NOTE: After unpacking unit, inspect carefully for any damage that may have occurred during transit. Check for loose, missing or damaged parts.

6. All wiring should be done by a qualified electrician, using copper wire only and in accordance with the National Electrical Code (NEC), all applicable code and ordinances, and all sections of this manual. Any variance voids the warranty and may create unsafe conditions.

7. Special attention must be given to any grounding

information pertaining to this product. To prevent the risk of electrocution, the unit must be securely and adequately grounded. This should be accomplished by connecting a grounded conductor between the service panel and the grounding lug or green lead wire provided in the wiring compartment. To ensure a proper ground, the grounding means must be tested by a qualified electrician.

8. Do not insert fingers or foreign objects into the air curtain. Do not block or tamper with it in any manner while it is in operation. Do not touch it while in operation or just after it has been turned off, as some parts may be hot enough to cause injury.

9. This product must NOT be used in potentially

dangerous locations such as hazardous locations where flammable, explosive, chemical laden, or wet atmospheres are present.

10. Do not attach ductwork to this product or attempt to

use it as a make-up air heater. Such use voids the warranty and may create unsafe conditions.

WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT USE THIS AIR CURTAIN WITH ANY SOLID STATE SPEED CONTROL DEVICE.

MOTOR

Installation

1. Using template provided, determine mounting location.

2. Drill holes and attach mounting hardware (not included).

IMPORTANT:THE HARDWARE AND THE SUPPORTING STRUCTURE MUST BE CAPABLE OF SUPPORTING A MINIMUM 150 LB. LOAD.

NOTE: All installation should be done to meet local building code.

3. Mount cabinet on wall and securely tighten hardware.

4. Replace motor/blower assembly in cabinet. Secure two wing nuts on blower base. Reconnect motor electric cord plug assembly.

5. Replace intake grille with louvers facing down and refasten knurled nuts.

ELECTRICAL CONNECTIONS

WARNING: ALL AIR CURTAINS SHOULD BE INSTALLED BY QUALIFIED PERSONNEL.

1. Connect motor per nameplate to correct power supply. Use adequate size wire for all branch and feeder runs.

2. Install all wiring, protection and grounding in accordance with the National Electrical Code (NEC) and all local requirements.

WARNING: THIS FAN HAS AN INTERNAL SELF RESETTING THERMAL OVERLOAD PROTECTOR. ALWAYS DISCONNECT FROM POWER SUPPLY BEFORE SERVICING.

3. Remove two screws from switch box and remove cover.

NOTE: Motor is prewired to high/low toggle switch. (See wiring diagram, Figure 5.)

4. Run wires from power supply to switch box using appropriate wiring according to local code. (Use a flexible connector to allow for possible angle adjustment.)

5. Connect wires to the two lead wires provided with wire nuts (not included). Connect black supply to center terminal of rocker switch, white neutral to white (for 220 volt units, L2 will connect to black or white with black tape lead), green grounding lead to grounded conductor of supply circuit. No loose strands or loose connections should be present. After splices are made, wires should be spread apart so that the green and white wires are on one side of outlet box and the black wires are on other side. Turn splices upward and carefully push all wiring into outlet box.

6. Replace switch box cover.

7. Unit is ready for operation.

CAUTION: Make sure amp rating of any ON/OFF switch exceeds nameplate amp rating of motor.

8. Restore power.

NOTE: Air curtain has high/low selector switch. See Operation section for proper setting instructions.

9. Upon completion of all installation, inspect unit for excessive vibration during operation. If excessive vibration is noticeable, disconnect power supply. Inspect mounting installation and refer to Troubleshooting Chart for probable cause.
