General Information
The PureAirt air purification system uses photocatalytic
oxidation (PCO) technology to significantly reduce levels
of airborne volatile organic compounds, cooking odors,
common household odors, airborne dust particles, mold
spores and pollen. The PureAirt system is available in
three models: PCO14−23, PCO16−28 and PCO20−28.
Each unit may be connected to either 120VAC or 230VAC
power supply. If 230VAC power supply is used, a 230VAC
power cord must be ordered separately.
Lab tests confirm a 50% reduction in total volatile organic
compounds (TVOC) within the first 24 hours of initial op-
eration of the PureAirt air purification system. It may take
up to 48 hours after initial system start−up to reduce the air-
borne chemicals that have built up in a home over a long
period of time.
For peak performance, unit should be installed in homes
with TVOC levels that are less than 1000 µg/m
3
. Home
source removal and ventilation may be required to lower
TVOCs to this level.
NOTICE
This system is NOT intended to be used for removal
of active mold growth or continuous sources of
high levels of chemicals in the air.
For existing mold growth, the mold must be proper-
ly removed PRIOR to installation of the PureAirt air
purification system.
WARNING
Risk of property damage, injury, or death.
Installation and service must be performed by a
qualified installer or service agency.
WARNING
Electric shock hazard.
Can cause injury or death.
Disconnect all electrical power supplies before ser-
vicing. Access panels must be in place during ap-
pliance operation.
CAUTION
Sharp edges hazard.
Sharp edges can cause injuries.
Use protective gloves when grasping equipment
edges.
NOTICE
Possible odor emissions. Chemical reactions may
cause temporary odors after initial start−up or after
lamp replacement. Odor may also be present after
paint, cleaning solutions or hobby materials have
been used in the conditioned space.
Some occupants may experience irritation or dis-
comfort during this period. If the irritation or dis-
comfort lasts longer than 48 hours, the homeowner
should be advised to contact a Lennox dealer.
Unique Field−Supplied Installation Items
S Cotton gloves and cloth (to remove fingerprints from
lamps)
S Aluminum foil tape or water−based mastic (NOT sili-
cone) to be applied as a sealant.
