The Fresh-Aire UV® Tubular Rack System is designed for installation into commercial air handling units for the
purpose of surface or airborne disinfection using ultraviolet germicidal irradiation. For maximum
installation exibility and cost-eectiveness the UV lamps are mounted onto a framework of
standard 0.5”EMT tubing (not included). 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 number and placement of lamps is determined by several factors
including coil dimensions and whether surface or airborne disinfection is
desired. A Fresh-Aire UV® commercial UV specialist can help congure the
best system for your application.
As a general rule, standard output UV lamps are recommended for surface
treatment applications. Higher output lamps and power supplies are only
recommended for airborne treatment. Both types of systems may be
installed in a similar fashion with the same mounting hardware.

*Installation of this product by anyone other than licensed HVAC or electrical contractors voids warranty.
COMMERCIAL SERIES
TUBULAR RACK SYSTEM
INSTALLATION & MAINTENANCE

System Conguration
1. Determine the dimensions of the coils or area to be irradiated.
2. Use the following guidelines to estimate the number of lamps
needed for proper coverage.
Fresh-Aire UV oers a free system conguration consultation service for commercial
projects. Contact Fresh-Aire UV for details.
UV Lamp Conguration Guidelines
• Maximum germicidal eectiveness is within an 18” radius from UV lamp center axis
• The optimal distance between UV lamp(s) and the irradiated surface is 12”
• The distance between stacked UV lamps should not exceed 35”
• The distance between end to end UV lamps should not exceed 12”
• The distance of UV lamp ends to the edge of irradiated surface should not exceed 6”
3. Before attaching the L-Brackets for mounting use the Optimal Irradiation
Distance and Lamp Spacing diagrams to conrm that when installed the UV
Lamps will be positioned properly.
4. UV lamps are mounted onto a framework of EMT tubing. When 2 or more UV lamps
are supported on a single length of EMT it is recommended to use the Optional
Vertical Support Kit.

1Assemble Conduit Framework
1. Measure and cut tubing to length then slide on conduit/
lamp clamps (do not fully tighten bolts yet).
1a. Use Optional UV Shields when there are materials (such
as older brittle insulation, lter media etc.) in the air
handler which may be damaged by UVC exposure. Snap
the shield onto the lamp ends, rotate into position .
2. Use self-tapping screws to attach L-Brackets to the air
handler wall or supporting structure. Then use the ½” Pipe
Clamps to attach tubing sections to the L-Brackets.
3. Optional 12” Stand-o adaptors are available if there is no
suitable wall surface for mounting parallel to the coil.
Use self-tapping screws to attach ½” Pipe Clamp onto the
end of the stand-o. Mount the stand-o with more screws.
Then use the ½” Pipe Clamps to attach tubing sections to
the end of the Stand-o.
3a. Alternate Mounting: Attach L-Bracket with ½” Pipe
Clamps to interior of Stand-o. Then use the ½” Pipe
Clamps to attach tubing sections to the L-Bracket. This
allows lamps to be positioned less than 12”from coil.
4. Optional Vertical Support adds strength to the conduit
tubing support framework and prevents sagging on
installations with two or more lamps per tubing length.
Measure the distance from oor to ceiling then measure
and cut tubing 1.75” less than that length. Use the ½” Pipe
Couplings to extend the Vertical Support to oor and
ceiling for a snug t.

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 ceramic lamp tip
on the other end. DO NOT clamp onto the lamp glass. Use Black
Nylon Zip-Ties to secure lamp cables to Tubular Rack components
and/or supports.
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. The power supply is weather
resistant and is suitable for mounting inside or outside of the air
handler. 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
handler for connections.
2. IMPORTANT! Turn o main power before making electrical
connections. Refer to the Electrical Diagram for proper
connection of the power supply to the main power.

IMPORTANT! Connect in accordance with all state and local
electrical and building codes. Proper voltage is automatically
selected by the unit between 120–277 VAC Single Phase 50/60 hz.
IMPORTANT! An external power suppressor is suggested if
power surges occur often.
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 monitor and alert
maintenance personnel when UV lamps should be replaced.

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 UV lamps, power supplies, and cables are in place
join the lamp and power supply cables by aligning the
electrical pins and anges on the rubber connectors and
pushing them rmly together.

5Sight Glass Installation
1. The sight glass allows safe viewing of the UV light system when in operation. Find a
suitable location such as a door to the HVAC system for the sight glass.
2. Drill a 1” hole and press the base of the sight glass through it.
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 passed their rated life span 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.
Important! Use only Fresh-Aire UV® replacement lamps.
Use of replacement lamps from other manufacturers voids
the warranty.
9Trouble Shooting
