APPLICATION CONSIDERATIONS
The Perfect Airt Purifier is designed for use in the return air
duct of a forced air heating, cooling, and ventilation system.
Models GAPAAXBB1625 and GAPAAXBB2025 are
specifically designed for use in systems with a forced air gas
furnace.
Air Conditioning
The Perfect Airt Purifier should be installed in a system so
that all the return air is circulated through the air purifier. It
should be located upstream of both the furnace and the air
conditioning evaporator coil. This will help keep the furnace
and evaporator coil clean and prevent condensation from
forming within the Perfect Airt Purifier.
Humidifiers
An evaporative humidifier can be mounted upstream of the
Perfect Airt Purifier. It is best to install atomizing humidifiers
downstream of the air purifier because hard water salt deposits
and water droplets may damage air purifier. If an atomizing
humidifier must be mounted upstream of the Perfect Air t
Purifier, it should be mounted as far upstream as possible (at
least 6 ft recommended), and a standard disposable furnace
filter should be mounted between the humidifier and the air
purifier to trap hard water salt deposits and water droplets.
Transitions
If the return air duct or furnace openings do not fit the Perfect
Air t Purifier cabinet openings, gradual transitions are
recommended to reduce air turbulence and maximize efficiency.
No more than 20 degrees (about 4 in. per running ft) of
expansion should be used on each side of the transition fitting.
Turning Vanes
If the Perfect Airt Purifier is installed adjacent to a 90 degree
duct elbow, turning vanes should be added inside duct to
improve air distribution across the face of the air purifier.
Electrical Power
The Perfect Airt Purifier should only be powered when airflow
is present. The furnace control EAC terminals provide power
only when the furnace blower is operating. Perfect Air t
Purifier models GAPAAXBB1625 and GAPAAXBB2025 are
designed to be powered from the electronic air cleaner (EAC)
terminals on a furnace electronic control. If EAC terminals are
not available, an alternative airflow sensing mechanism must be
used to ensure the Perfect Airt Purifier is only powered when
airflow is present. Contact local Bryant distributor for
information on approved alternatives.
