Installation & Maintenance of the Fresh-Aire UV®
Airborne Duct System for Commercial HVAC Systems
The Fresh-Aire UV® Airborne Duct System is designed for installation into
commercial HVAC system ducts for the purpose of airborne disinfection using
ultraviolet germicidal irradiation. For maximum installation flexibility and
cost-effectiveness the UV lamps are mounted onto a framework of standard 0.5”
EMT tubing. The remotely mounted weather resistant power supply can withstand
the wet environment found inside of air handlers or the exposed conditions of
outdoor packaged air conditioning systems. As a general rule, standard output
UV lamps and power supplies are recommended for surface treatment
applications. High output lamps are typically recommended for airborne
treatment. Both types of systems may be installed in a similar fashion with
the same mounting hardware. The Airborne Duct System can use from one to six
UV lamps depending on the application.

Individual Parts
System Configuration A: In-Line With Air Flow (pre-assembled parts are ready for this configuration)
- Cut an access panel into the duct. If necessary cover high exposure areas with UV-resistant reflective tape or similar material.
- If needed, loosen or remove hardware then cut conduit to fit duct.
- Mount the frame-work into the duct using the self-tapping screws or optional mounting magnets.
Configuration A Assembled
System Configuration B: Diagonal To Air Flow
- Cut an access panel into the duct. If necessary cover high exposure areas with UV-resistant reflective tape or similar material.
- Remove hardware then cut conduit to fit duct.
- Re-attach hardware in the configuration below.
- Adjust the angle of the mounting brackets so the UV lamps will cross the air-stream diagonally. Mount the frame-work into the duct using the self-tapping screws or optional mounting magnets.
Configuration B Assembled 
Install UV Lamps
Snap UV Lamps into the Lamp/conduit Clamps. Be sure to clamp to the rubber lamp connector on one end and the plastic lamp tip on the other end. DO NOT clamp onto the lamp glass.
Mount Power Supply(s)
Mount the power supply in a location (inside or outside of the HVAC system) that is convenient for access to the main power supply and for connection to the UV lamps. An Optional Power Supply Panel Mount (part # TUVC-P) is available for mounting two or more power supplies.
- Use the supplied self-taping sheet metal screws to mount the power supply in place through the mounting holes on the sides of the base. It is recommended to use wire boxes, our Optional 3/4” or 1” Cable Strain Relief, or other sealing methods in order to pass the power cord and lamp cables into the interior of the air duct for connections.
- IMPORTANT! Turn off main power before making connections. Refer to the Electrical Diagram for proper connection of the power supply to the main power.
Electrical Diagram IMPORTANT! Connect in accordance with all state and local electrical and building codes. Proper voltage is automatically selected by the unit between 120 or 230 VAC Single Phase 50/60 hz.
IMPORTANT! External power suppressor may be needed if power surges occur.- Use of Optional Door Interlock Switches is highly recommended to prevent accidental exposure to UV Light. Interlock switches are mounted on the access panels and doors so the UV lights turn off when the entryway is opened.
- Use the Optional UV Output Monitor, to alert maintenance personnel when UV lamps should be replaced.
Connect Lamps & Cables
Arrange cables as needed for installation. If necessary use the Optional 3/4”
or 1” Cable Strain Relief to pass cables through cabinets, air system walls,
etc. Optional 5’, 10’, 20’ Cable Extensions are available for longer runs.
When UV lamps, power supplies, and cables are in place join the lamp and power
supply cables by aligning the electrical pins and flanges on the rubber
connectors and pushing them firmly together.
Sight-Glass Installation
- Find a suitable location such as a door to the HVAC system and apply the UV warning/lamp replacement sticker.
- Drill a ½” hole through the orange circle on the sticker. Press the sight glass into hole.
Power-up System
Caution: UV-C light that can cause Serious Eye Burns and Temporary Blindness, Ensure all access panels have been replaced and doors closed before powering- up the system. Turn on the main power then switch on the UV light power supply(s). Use the sight glass to confirm that the UV Lamp(s) is operating.
UV System Maintenance
Periodically wipe the UV lamps with a clean cloth or alcohol swab to remove any accumulated dust or dirt. This should be performed at least every 6-9 months or during routine maintenance intervals. Fouling could occur if lamps are installed under chilled water lines. Wipe clean or install optional shield.
UV Lamp Replacement
Fresh-Aire UV® lamps are rated for either one or two years germicidal effectiveness. The lamps will continue to glow after they have expired but their germ-killing effectiveness diminishes with time so they must be replaced on schedule for the system to function properly. Contact your local dealer for replacement lamps.
