Never expose eyes or skin to UVC light from any source. Looking directly at the UVC
light may cause permanent eye damage or blindness. Never operate the CX-Pro Air Purifying System out
of the plenum. Avoid touching the glass portion of the lamp with your hands.
WARNING
SAFETY INSTRUCTIONS
Never expose eyes or skin to UVC light from any source.
• Looking directly at the UVC light may cause permanent eye damage or blindness.
• Never operate the CX-Pro Air Purifier out of the plenum.
• Designed for a closed duct system. Do not mount near a supply or a return air opening.
• All duct openings in direct line of site of the UVC light must be sealed with aluminum tape or
equivalent sealing methods.
UVC light will break down plastic materials not rated for UV exposure, like wire
insulation, flex duct, drain pans, humidifiers, etc.
• The unit must be mounted at least 30" from the above stated types of materials.
• If it is necessary to mount the unit in direct line of sight of these types of materials, they must
be shielded with aluminum foil, aluminum foil tape, or sheet metal.
DO NOT mount this unit outdoors.
• This product is designed for indoor installation only (i.e. attics, crawl spaces, basements, etc.).
Never touch broken lamp or internal contents of lamp. The lamp contains mercury.
• After opening the carton, unpack and inspect the unit and lamp for damage. Do not install
this unit if any damage is noticeable. If lamp is damaged, cracked or broken, do not touch
lamp or other contents in carton. Close carton and return to seller immediately.
• In case of accidental exposure to internal contents of lamp, wash hands and any other affected
skin area with mild detergent. Remove affected clothing immediately. If skin surface is pierced,
seek medical attention immediately.
NOTE: If you touch the glass of the lamp, you should wipe the glass clean with isopropyl
alcohol and a lint free wipe. If the lamp is not cleaned, the film from hand oils will cause a
reduction in the light intensity.
Before installing or servicing a humidifier, air filter, HVAC system, or this unit,
etc., always turn all power OFF and have unit unplugged. Electrical shock can cause personal injury
or death. Never expose eyes or skin to direct UVC light from any source.
To prevent water damage or electric shock, do not mount unit under a humidifier.
This product is designed for indoor installation only (i.e. basements, crawl spaces,
attics, etc.). For use on gas fired, oil fired, electric and split system heat pump forced air systems*. This
product is NOT designed to be mounted outside on gas fired or heat pump packaged units**.
* Split system heat pumps are systems where the air handler and the air conditioning compressor are separate units.
** Packaged units are systems where the air handler and the air conditioning compressor are built together and are installed
outside of the building.

WARNING
INSTALLATION
STEP 1. CHOOSE A LOCATION FOR THE CX-PRO
To prevent water damage or electric shock, do NOT mount unit under a humidifier.
A. CX-Pro may be installed in supply duct, return plenum or above AC coil.
B. CX-Pro may be installed in upflow, downflow, or horizontal flow ducts and plenums.
C. CX-Pro may be installed directly onto a sheet metal air duct, or onto a fiberglass ductboard
when installed using the included ductboard adapter plate.
D. If locating a CX-Pro above an AC coil: position so that the maximum surface area of the AC
coil is illuminated, installing as close to the AC coil as possible without damage to the AC coil.
E. DO NOT locate within 30 inches (direct exposure) of plastic materials or air filters.
Use care to avoid damage to the AC coil, wiring or other components while
installing the CX-Pro.
STEP 2. UVC LAMP & BALLAST
Unplug the unit before installing the lamp.
A. The ballast is factory set to 120 VAC. The voltage can be changed in the field to 230 VAC by
sliding the voltage selector switch to the 230 volt position (Figure 1). The plug must be replaced
and wiring must be done to applicable electrical codes.
B. Remove front electrical cover by removing (2) sheet metal screws on sides.
C. Do not touch the glass section of the lamp with bare hands. Wear oil-free cotton gloves when
handling germicidal lamp.
D. Remove lamp from packaging and slide non-pinned end through grommet.
E. Loosen lamp clip and insert lamp so that the end of the lamp is inside the unit.
F. Tighten lamp clip using the brass knurl. ake sure the lamp clip tightens around the plastic
part of the lamp and not the glass (Figure 2).
G. Connect ballast to the four pins on the lamp using the connector (Figure 3).
H. Wipe down the lamp with the supplied alcohol wipe.

WARNING
INSTALLATION
STEP 3. INSTALL THE CX-PRO
A. Hold or temporarily tape the included ductboard adapter
plate in the location chosen for installation. Using the plate
as a template, mark the mounting surface (sheet metal air
duct or fiberglass ductboard) using the outermost slots in the
plate (Figure 4). Alternatively, a 5-3/8” square may be marked
on the mounting surface.
B. Cut out the opening for the CX-Pro in the mounting surface,
making sure to cut slightly outside the marked lines if the
ductboard adapter plate was used as a template.
C. If mounting the CX-Pro on a ductboard: attach the duct-
board adapter plate to the opening by folding the inner
flaps of the plate into the opening and fully back against the
inside of the opening in the ductboard, either from the sides
or from top and bottom of the plate. Finish the ductboard
installation by sealing around the edges of the plate to the
ductboard, using mastic foil tape or other material suitable
for sealing duct joints.
D. Insert the CX-Pro into the duct opening and attach it to the
duct or ductboard adapter plate with the (4) included sheet
metal screws. The wider side of the V-shape of the CX-Pro’s
panels should face into the oncoming airstream (Figure 5).
Not : Pay attention to directional airflow arrow for proper
installation.
E. Reattach electrical cover using (2) sheet metal screws previously removed in step 2B.
STEP 4. CONNECTION
A. Attach the quick connect power cord and plug into any standard 120 volt electrical outlet.
B. Verify lamp operation by looking through the view port on front cover.
Not : Continuous UVC germicidal lamp operation is recommended. At .09 cents per kilowatt
hour, continuous lamp operation cost 10.5 cents per day. Cycling the UVC germicidal lamp on
and off degrades lamp performance much faster and shortens the filament life .

WARNING
TROUBLESHOOTING
Only qualified personnel should work on electrical equipment. Working on or
near energized equipment could result in death or serious injury.
1. Check that the supply voltage to the unit and the ballast voltage setting match.
2. Be sure the lamp connector is fastened securely.
3. Check for loose electrical connections.
4. Test with new lamp. If lamp still does not light, replace ballast.
RECOMMENDED MAINTENANCE
Disconnect power to the transformer and unplug the 120V quick connect power
cord before commencing inspection and cleaning.
NOTE: Wear oil-free cotton gloves prior to maintenance in case of accidental breakage of glass.
1. The lamp should be inspected and cleaned at least every 6 months. Frequency depends upon
the environment such as the type of air filter, duration of use and replacement cycle.
2. To maintain maximum output intensity, replace the CX-Pro-RL lamp every 2 years. The lamp
should operate continuously for maximum lamp life and light effectiveness.
3. Do not attempt to clean the catalytic aluminum substrate with cleaning solutions. The catalyst
is radiated with short wave ultraviolet light during periods of non-airflow and is self-cleaning.
If there is a buildup blocking the catalytic cells, sit the unit on end, on a flat surface, with elec-
trical enclosure facing up. Use low-pressure, compressed air to blow the surface of the catalytic
cells free of blockage.
