APPLICATION CONSIDERATIONS
The Perfect Air 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 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 purifier.
Humidifiers
An evaporative humidifier can be mounted upstream of the
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 purifier, it should be mounted as far
upstream as possible (at least 6 ft./1.8 m 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.
Ensure that the humidifier installation will not allow water or water
droplets to enter the air purifier because it may cause electrical
arcing or damage the air purifier.
NOTE
: For fan coil installations, do not install the humidifier in
the fan coil access doors or cabinet.
Inspect for plugged drains and maintain humidifier drain lines on a
regular basis to avoid overflow of water into the air purifier. The
recommended inspection should be done at every change of the air
purifier cartridge (minimum, annually).
HIGH VOLTAGE HAZARD
Failure to follow this warning could result in personal injury
or death.
This air purifier utilizes high voltage. If you notice water
running into or around the air purifier, water stains on the
purifier cartridge or on the Enhancement Module walls or
cabinet, shut off the air purifier and call your service provider.

WARNING
Transitions
If the return air duct or furnace openings do not fit the purifier
cabinet openings, gradual transitions are recommended to reduce
air turbulence and maximize efficiency. No more than 45
_
(about
8.5 in. per running ft.) of expansion should be used on each side of
the transition fitting.
Turning Vanes
If the purifier is installed adjacent to a 90
_
duct elbow, turning
vanes should be added inside duct to improve air distribution
across the face of the air purifier.
Electrical Power
The 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 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
purifier is only powered when airflow is present. Contact local
Bryant distributor for information on approved alternatives.
