About pureAir HVAC
pureAir HVAC is a new generation Air Purication Enhancement System.
Designed to work with existing purication technology to reduce odors,
smoke, and a broad spectrum of indoor air contaminants.
pureAir HVAC is easily mounted into air conditioning and/or heating systems
where contaminants can grow. When the HVAC system is in operation,
pureAir HVAC produces the PCO (Photocatalytic Oxidation) Process
consisting of hydroperoxides and superoxide ions, which are friendly oxidizers
that revert back to oxygen and hydrogen after the oxidation of a pollutant.
Cautions & Warnings
WARNING: UV Light in operation. Disconnect unit from power
supply before servicing. Failure to follow warnings may result in
severe eye damage.
CAUTION: To reduce the risk of shock, this equipment may have
a grounding type plug with a third (grounding) pin. This plug will
only t into a grounding type power outlet. If the plug does not t
into the outlet, contact a qualied electrician or HVAC specialist to
install the proper outlet. DO NOT alter the plug in any way.

The unit should be installed after the air handler in
the HVAC system in the supply plenum.*
*Additional pureAir HVAC units are recommended in
the Return Plenum for added protection and to keep
the internal parts clean.
An opening of will need to be cut into the existing
duct work to install the unit properly.
Electrical Requirements
The unit is powered by connection to 24VAC
from HVAC System or 24VDC from
120VAC transformer (included).
WARNING: Long term use of an extension cord is not recommended due to safety considerations.

Installation
1. Locate a suitable area of duct for
the installation.
2. Cut away any insulation to expose
the duct.
3. Use the Mounting Plate to trace the
main hole and the Eight (8) Screw
Hole Locations.
4. Use the Drill with 1/8” Drill Bit to make
Four (4) holes around the marked
cut out (used in Step 5) as well as
the Eight (8) Screw Holes (used in
Step 7).
5. Use the Tin Snips to cut around the
traced hole.
6. Remove the backing from the
Mounting Plate Adhesive Gasket
and press onto the duct over the
cut opening.

Installation (Continued)
7. (A) Install the Mounting Plate to the
Duct using the Eight (8) Self-Tapping
Screws.
(B) For Fiberglass Ductwork, attach using
the 2” Bolts with Toggle Bolt Anchors.
8. Place the unit through the hole
and rotate is so that airow always
passes through the honeycomb. The
mounting plate and unit head are
set up to allow for any orientation.
Alternatively, the PCO Cell can be
reoriented on the back to allow the
Power Cable to always face the the
ideal direction. (Review “Changing
the Cell” on Page 9 for instructions)
9. Thread the four (4) Knurled Thumb
Nuts onto the Threaded Bolts,
making sure a seal is created along
the backside of the Ballast Housing.
10. Plug the power cable into your unit
and then into the outlet.

Mounting Bracket over the back of
the PCO Cell, with the screw hole
overlapping the open screw hole of
the Ballast Housing.
NOTE: Do not cover the open cell sides.
5. Replace the screw to hold the DBI
Cell Mounting Bracket in place.
6. Place the DBI Cells by lining up to
tabs and inserting them into the DBI
Cell Socket. Rotate 90° to lock them

Maintenance/UV Lamp Indicator
Cell Disposal
Please do not throw a used PCO Cell in the garbage. The special germicidal
UVC bulb used in the unit contains a very small amount of mercury.
Be sure to dispose of them properly according to local regulations.
Your pureAir HVAC unit requires no periodic maintenance beyond the
normal replacement of the PCO Cell every year. It is recommended, for
optimum performance, that the PCO Cell be replaced annually.
The UV Lamp Operation Indicator on the face of the unit will glow when the
unit is in use. If the indicator does not glow and the unit has power, the PCO
Cell needs replacing.
