PUREAIR™ AIR PURIFICATION SYSTEM
PHOTOCATALYTIC OXIDATION TECHNOLOGY(PCO)
INSTALLATION AND MAINTENANCE INSTRUCTIONS FOR CASED PUREAIR™ MODELS PCO-12C-2, PCO-20C-2
General
The PureAir™ air purification system helps to significantly reduce levels of airborne volatile organic
compounds, cooking odors, common household
odors, airborne dust particles, mold spores, and
pollen in residential spaces. The PureAir™ air purification system (cased model) includes a MERV 9
pleated filter, UVA lamps, and a metal insert that is
coated with a titanium dioxide catalyst. As air enters
the system, a percentage of airborne particles and
bioaerosols, such as mold and bacteria, ranging in
size down to .3 microns, are captured by the pleated filter. The smaller airborne particles, odors, and
chemicals continue through the system. The UVA
lamp activates the catalyst on the metal insert. The
catalyst combines with water vapor in the air to form
hydroxyl radicals that destroy a percentage of the
remaining odors and chemicals.
In laboratory & field tests, we found greater than
(TVOC) within 24 hours of initial installation and
operation of the PureAir™ air purification system.
When the system is first started, it may take up to 48
hours to reduce the airborne chemicals that have
built up in your home over a long period of time.
After that period, there will be a balance between
chemicals emitted inside your home and chemicals
removed by your PureAir™ air purification system.
Please refer to the included Homeowners IAQ guide
for other measures to improve indoor air quality.
The PureAir™ air purification system is NOT intended to be used for
removal of active mold growth or continuous source of high levels
of chemicals in the air. For existing mold growth, the mold must be
appropriately removed PRIOR to installation of your PureAir™ air
purification system.

Installation
UNPACKING THE PCO-12C/20C (Fig. 1)
The MERV 9 pleated filter has been vapor barrier
packaged. The metal insert has been vacuum
packaged. All protective wrapping MUST BE
removed prior to installation and operation of
system.
Remove carbon
pouch inside metal
insert packaging.
Fig. 1 Remove and discard all wrapping and packaging
material prior to installation and operation of PCO-12C/20C.
SELECTING A LOCATION(Fig. 3)
Install the PCO-12C/20C ONLY in the return air
duct upstream of the supply blower. Allow approximately 30" of clearance in front of access door to
slide out the PCO-12C/20C assembly. This provides easier access to change the pleated filter,
metal insert, and UVA lamps.
Allow approximately
30" of clearance.
CHECKING THE LAMPS (Fig. 2)
Lamps are factory installed as shown below. Make
sure that the lamps have not become disengaged
during shipping. Use cotton gloves or cloth to
avoid fingerprints on the lamp.
Excessive force
may damage
plastic socket.
Fig.2 Verify proper installation of lamps.
CAUTION
Fig.3 Install PCO-12C/20C in the return air duct.
CAUTION
Sharp edges hazard.
Equipment sharp edges can cause injuries.
Use protective gloves when grasping equipment edges.
NOTICE
Unpacking required.
Remove all protective packing material from the
pleated filter and the titanium dioxide metal insert.
All packing material should be discarded properly
in refuse containers.
NOTICE
Clean lamps prior to installation using a cotton
cloth to remove dirt and fingerprints.
Failure to clean lamps could reduce the system's
efficiency
Lamps contain Mercury.
Ingestion or contact with mercury or mercury vapor
is hazardous to your health.
Take care when handling lamps. If lamp is broken,
avoid contact with mercury.
NOTICE
Intended for return air duct installation only.
Improper installation can damage HVAC system,
PureAir™ or other equipment and may void warranty.
