Before Installing this Product

Read these instructions carefully; failure to follow them could damage the product and

cause a hazardous situation.

Installer must be a trained, experienced service technician.

WARNING: UV Light Hazard.

Harmful to bare skin and eyes. Can cause temporary or permanent loss of

vision. Never look at lamps while illuminated.

• To prevent exposure to ultraviolet light, disconnect power to the ultraviolet air

treatment system before servicing any part of the heating/air conditioning system.

• View illumination only through lamp handle or sight glass.

• Do not attempt to bypass duct mount switch.

• Do not attempt to open housing; unit is sealed to prevent ultraviolet light

exposure.

CAUTION: Personal Injury Hazard. HVAC power supply can cause

electrical shock.

Disconnect HVAC power supply before installing, cleaning or replacing ultraviolet

lamp(s).

CAUTION: Breakable Glass Hazard. Can cause personal injury.

• Be careful when inserting lamp(s) into lamp base.

• Wear protective gloves when handling lamp(s).

CAUTION: Personal Injury Hazard. Power supply can cause electrical

shock.

• Disconnect power supply before cleaning or replacing ultraviolet lamp(s).

• Do not open base unit or lamp handle; there are no user-serviceable compo-

nents inside.

Typical Mounting Locations

We recommend the UV Air Purifier be installed on the supply side duct 3–5 inches

above the A-coil, but it can also be installed on the return side if necessary. See

Figures 1 and 2.

The germicidal UV light should be positioned to shine on the surfaces that are prone

to mold growth like the A-coil, or be placed in an open area of the return duct where

there are long straight runs.

WARNING: Do not mount device in location that allows ultraviolet light to be seen

after installation other than by the UV protected lamp handle or sight glass.

Important: Some materials inside the HVAC system (including filter media, flex duct,

wiring etc.) may not be UV light resistant. Cover materials affected by UV light with UV

shielding or reflective tape.

The AirBRIGHT™ Odor Absorber unit should be oriented so that the air flows past the

UV Light first then into the AirBRIGHT Odor Absorber.

Turn off main power source before installation. Model information is

printed on the Power Unit cover.

1. Unfasten panel to gain access to mounting location

2. Determine the optimal position for placement of the Air Purifier.

3. If necessary, use a utility knife to

cut the insulation on the inside of

the duct.

4. Clean surface of glue, dust, etc.

7. Rotate the lamp handle clockwise

until it snaps in place.

9. Use foil tape to close the cut in the

insulation as needed.

10. Create a 5/8 (0.625) in. hole in the

duct and pass the cord through it. Clip

the bushing provided onto the cord at

a point close to the hole. Plug the hole

with the bushing.

M34601

M34602

12. Find a suitable location on the

outside of the duct-work near the

UV Lamp installation and apply the

warning/lamp replacement sticker.

13. Drill a 1/2 in. hole through the circle

on the sticker. Press the UV sight

glass into hole.

11. Secure access panel to the duct work.

Option 2

External Mounting for Metal Duct Applications

1. Use the gasket to mark the duct openings. Cut and remove openings, making sure

to cut 1/8-inch outside of the markings to create enough room for the product. If

using a hole saw to cut circular opening, use a 2-inch diameter bit.

M34687

2. Push the AirBRIGHT™ Odor Absorber

into the base until the two tabs on the

side click into place.

M34685

3. Remove one side of the backing from the gasket and stick

gasket on the ductwork so that the openings line up.

14

4. Peel away the other side of the backing on the gasket and insert AirBRIGHT™ into

the duct until the base sticks securely to the gasket.

5. Secure the base to the ductwork using self-tapping screws.

6. Insert lamp into base and turn handle clockwise to lock in place.

Option 3

Duct Board Mounting: For Duct Board Applications Only

1. Use the gasket to mark the duct openings. Cut and remove openings, making sure

to cut 1/8-inch outside of the markings to create enough room for the product. If

using a hole saw to cut circular opening, use a 2-inch diameter bit.

Power Supply Installation

• Find a suitable location for the power supply and mount using the self-tapping

screws.

• Use the wiring diagram on the next page to connect to power.

• When all the other components are properly installed connect the UV lamp cable

to the power supply cable.

M34663

ALIGN FLANGES

2.

1.

• Make sure the flanges are aligned

and then push the connectors

firmly together. A tight connection

ensures a proper water-resistant

seal. See image at right.

• Turn on the power and use the

lamp handle or sight glass to

confirm that the UV Lamp is

operating.

Power Supply Wiring

WARNINGS:

• Draws 16 VA, do load calculation to determine if a separate transformer is

needed.

• Systems with high 24 VAC loads may require the installation of a separate 24

VAC transformer to power the UV light.

• Always use a separate 24 VAC transformer with “communicating” air systems.

Maintenance

Note: Lamps should be replaced every year. UV lamps will continue to emit visible

light but lose germicidal effectiveness after approximately one year.

Changing UV Lamp

1. Disconnect the power to your heating and cooling system.

2. Unplug or turn off power to your UV System and allow the lamp to cool for at least

15 minutes.

3. Rotate the lamp handle counterclockwise, as shown below, and gently pull the

lamp handle to remove the lamp.
