Installation & Maintenance of the Fresh-Aire UV®
Exhaust Odor System for Commercial HVAC Systems
The Fresh-Aire UV® Exhaust Odor System is designed for installation into
commercial HVAC system ducts for the purpose of exhaust odor control
using Fresh-Aire UV oxidation UV. For maximum installation exibility and
cost-eectiveness 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.
The Exhaust Odor System uses dual 18” oxidizing UV lamps that produce
ozone to reduce odors in exhaust air. WARNING

System Conguration B: Diagonal To Air Flow
1. Cut an access panel into the duct. If necessary cover high exposure
areas with UV-resistant reective tape or similar material.
2. Remove hardware then cut conduit to t duct.
3. Re-attach hardware in the conguration below.
4. 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.

4Connect 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 adding lamp extensions, 20 ft. is the maximum
distance from power supply to the lamp.
Align pins with lamp key then push rmly together.
Push Firmly Together
IMPORTANT!
Make sure connection is rmly seated with maximum
0.6” (15mm) gap between cable and ridge.

2Install 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.
3Mount 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.
1. 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.
2. IMPORTANT! Turn o main power before making connections.
Refer to the Electrical Diagram for proper connection of the
power supply to the main power.

IMPORTANT! External power suppressor may be needed if
power surges occur.
3. 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 o
when the entryway is opened.
4. Use the Optional UV Output Monitor, to alert maintenance
personnel when UV lamps should be replaced.

5Sight-Glass Installation
1. Find a suitable location such as a door to the HVAC system and apply the UV warning/lamp
replacement sticker.
2. Drill a ½” hole through the orange circle on the sticker. Press the sight glass into hole.
6Power-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
conrm that the UV Lamp(s) is operating.
7UV 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.
8UV Lamp Replacement
Fresh-Aire UV® lamps are rated for either one or two years germicidal eectiveness. The lamps will continue to glow after they have
expired but their germ-killing eectiveness diminishes with time so they must be replaced on schedule for the system to function
properly. Contact your local dealer for replacement lamps.
Part# TUVCL-118HO-OS-100 (high-output 100% oxidation 1 year lamp)
Important! Use only Fresh-Aire UV® replacement lamps. Use of replacement lamps from other manufacturers voids the warranty.
