Congratulations for selecting the Perfect Airt Purifier for your
home c omfort system! The Perfect Airt Purifier is proven to
remove and kill airborne germs and allergens, including viruses,
bacteria, a nd mold spores. The Perfect Airt Purifier is a
cornerstone of Bryant’s Perfect AirtSolutions for providing
healthier, cleaner air in your home.
HOW IT WORKS
The Perfect Airt Purifier provides extremely high filtration
performance while killing captured contaminants, including
viruses, bacteria, and mold spores. The Perfect Airt Purifier
treats the entire air--stream through a state of the art, three--stage
process, exclusive to Bryant.
In stage one, the particles are electrically charged by a
precision--point ionization array as they enter the Perfect Airt
Purifier.
In stage two, the charged particles are electrically attracted to
the air purification cartridge, which is located within an electric
field.
In stage three, captured particles are killed by electrical current
flow and ion bombardment.
SAFETY CONSIDERATIONS
Improper installation, adjustment, alteration, service,
maintenance, or use can cause explosion, fire, electrical shock
or other conditions which may cause personal injury or property
damage. Consult a qualified installer, service agency, or your
distributor or branch for information or assistance. The
qualified installer or agency must use factory authorized kits or
accessories when modifying this product. Refer to the
individual instructions packaged with the kits or accessories
when installing.
Follow all safety codes. Wear safety glasses and work gloves.
Have fire extinguisher available. Read these instructions
thoroughly and follow all warning or cautions attached to the
unit. Consult local building codes and National Electrical Code
(NEC) for special requirements.
It is important to recognize safety information. This is the
safety--alert symbol
and in instructions or manuals, be alert to the potential for
personal injury. Understand the signal words DANGER,
WARNING, and CAUTION. These words are used with the
safety--alert symbol. DANGER identifies the most serious
hazards which will result in severe personal injury or death.
WARNING signifies hazards which could result in personal
injury or death. CAUTION is used t o identify unsafe practices
which may result in personal injury or product and property
damage. NOTE is used to highlight suggestions which will
result in enhanced installation, reliability, or operation.

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
GAPA
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.

CAUTION
CUT HAZARD
Failure to follow this caution may result in personal injury.
Sheet metal parts may have sharp edges or burrs. Use care
and wear appropriate protective clothing and gloves when
handling parts.
Step 7—Identify Mounting Location
a. Identify a mounting orientation for the Perfect Airt
Purifier in the return air duct (see Fig. 3).
b. Ensure airflow direction through the Perfect Airt Purif-
ier matches the a rrows on the face of the air purifier
cartridge. T he Perfect Airt Purifier can be rotated 180
degrees to accommodate the cabinet orientation.
c. The location of the Perfect Airt Purifier should be
readily accessible. Enough room should be provided for
periodic replacement of the air purifier cartridges.

START--UP AND OPERATION
Step 1—Checking Air Purifier Operation
!
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal
injury or death.
Before installing or servicing system, always turn off
main power to system. There may be more than one (1)
disconnect switch.
a. Attach the Perfect Airt Purifier door to the cabinet. A
magnet in the door (see Fig. 9) is used to activate a safety switch in t he power supply when the door is installed.
The power supply will not energize the air purifier unless the safety switch is activated.
b. Turn the HVAC system power on and adjust the
thermostat or Evolutiont System Control to activate
the system fan.
c. Turn the Perfect Airt Purifier power switch to on
position.
d. The power indicator light above the Air Purifier power
switch should illuminiate (see Fig. 8).
e. Check to ensure the light goes off when the Perfect
Airt Purifier power switch is set to off, when the
blower goes off, or when the HVAC system power is
turned off.
Step 2—Evolutiont Control
a. When the Perfect Airt Purifier is used with an
Evolutiont Control, the Evolutiont Control can be
configured to remind the homeowner when it is time to
change the Perfect Airt Purifier cartridge. This
maintenance reminder can be based on either the
TrueSenset dirty filter algorithm or time. The installer
WARNING

should use their discretion to select the most appropriate
option based on the initial system static pressure.
Step 3—Maximizing Performance
a. Maximum air purification performance is obtained
when the furnace blower is set for continuous operation
on the thermostat or Evolutiont Control.
