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.
