Typical Mounting Locations

We recommend the UV Air Purifier be installed on the supply side duct just 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 also 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 A-coil (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.

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.

• 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.
