BREATH OF
SPRING-FRESH AIR . . .
YEAR-ROUND
Congratulations on your excellent
choice and sound investment in this
addition to your home comfort
system.
Your electronic air cleaner represents
both the latest in engineering development and the culmination of many years
of experience from one of the most reputable manufacturers of comfort systems.
Your new unit is among the most
energy-efficient and reliable air filtration products available today. To assure
its dependability, spend just a few minutes with this booklet now. Learn about
the operation of your electronic air
cleaner and the small amount of maintenance it takes to keep it operating at peak
efficiency .
With minimal care, your electronic air
cleaner will provide you and your family with clean, healthy , and comfortable
air—from season to season, and year to
year.
Y OUR ELECTR ONIC
AIR CLEANING UNIT
Y OUR INDOOR AIR POLLUTION
SOLUTION
The highest value of clean air is in its
contribution to the good health and comfort of you and your family. Additional
benefits include potential savings in
home heating, cooling, and maintenance
costs.
Your new air cleaner will electronically
filter out microscopic particles as small
as 0.01 micron. At that size, it would
take 100,000 particles to cover the head
of a pin. Such particles are 500 times
smaller than the smallest grains of dust
trapped by conventional furnace filters.
Airborne pollutants commonly found in
the household are lint, dust, ash, pet hair
and dander, pollen, fungus, spores, bacteria, viruses, cooking grease, and possibly tobacco smoke odors.
By ridding your home of most of these
pollutants, the whole family can breathe
fresher, safer air. Moreover, family
members suffering from hay fever,
asthma, or allergies may find relief,
since electronic filtering removes man y
of the airborne particles responsible for
aggravating these ailments. Electronic
filtering removes airborne particles
before they have a chance to settle, so
walls, windows, draperies, and
furnishings stay clean and bright
longer.
If your home is equipped with central air
conditioning or a heat pump, electronic
air cleaning can optimize your system’ s
performance by keeping the indoor
coil clean. At today’s energy rates,
the potential savings can be
significant.
HOW YOUR AIR CLEANER
WORKS
Contaminated air enters the prefilter (the
mesh filter) where the larger airborne
particles are removed. These include
hair, fibers from carpets and drapes, pet
hair, and some lint particles. (See Fig.
1a.)
The air then passes through the ionizer/
collector cells. The ionizer wires produce positive ions that gi ve airborne particles a positive electrical charge.
(See Fig. 1b.)
Opposites attract: Airflow continues,
passing between the collector plates.
The positively charged particles are
attracted and trapped by the grounded
collector plates. (See Fig. 1c.) These
particles continue to cling to the plates
until you or your service technician
remove the plates for cleaning.
Meanwhile, the purified air leaves the
air cleaner and circulates into your living space. (See Fig. 1d.)

OPERATING YOUR
ELECTRONIC
AIR CLEANER
Your new electronic air cleaner is
designed to operate as part of your
heating/cooling system. After the air
cleaner is turned on, it will operate
whenever the furnace or air handler
blower is running.
Your electronic air cleaner will perform
at maximum efficiency if these recommendations are followed:
•
Consider running the heating/cooling
system blower continuously—day and
night, winter and summer . Continuous
blower operation provides for constant
air filtration. It may also contribute
to greater personal comfort since
continuous blower operation minimizes
temperature differences throughout
the home.

•
Supply-air and return-air grilles should
not be blocked. Drapes, furniture, and
toys are some of the items commonly
found obstructing grilles. Restricted airflow reduces the efficiency of the air
cleaner, as well as that of the whole
comfort system.
•
The electronic air cleaner must be
properly cleaned and maintained.
ST AR T-UP PR OCEDURES
1. Set the temperature control selector on
your indoor thermostat. Choose a setting above current room temperature if
heating is required. Set the temperature control selector below room temperature if cooling is needed.
2. Set the F AN mode on the thermostat.
When set to AUTO, the air cleaner
and system blower will run only
while the thermostat operates the
heating or cooling equipment. When
the F AN mode is set at the ON position, the air cleaner and blower will
run continuously—regardless of
whether the cooling or heating
equipment is operating.
3. Select operating mode of HEAT,
COOL, or AUTO.
4. Ensure the air cleaner’s door handle
is engaged, powering unit.
NOTE:
that power is available to the cells. It
does not indicate that power is a vailable
to the EAC.
NOTE:
ping) noise is normal during the operation of your air cleaner. Continuous
arcing, howev er , indicates that cleaning
is required. Refer to directions on cleaning your electronic air cleaner.

PROCEDURE
To disconnect the electrical power to
your air cleaner, disengage the air
cleaner handle. You may continue to
operate the rest of your comfort system,

PERFORMING ROUTINE
MAINTENANCE
With the proper maintenance and care,
your electronic air cleaner will operate
economically and dependably. Maintenance can be accomplished easily by
referring to the following directions.
However, before performing any maintenance, consider these important safety
precautions:
•
DISCONNECT ALL ELECTRICAL
POWER TO THE AIR CLEANER
BEFORE PERFORMING ANY SERVICE OR MAINTENANCE.
NOTE:
THAN 1 ELECTRICAL DISCONNECT SWITCH.
The prefilter and ionizer/collector cells
should be checked for dirt regularly.
Accumulated dirt needs to be removed
from these components to maintain efficient air filtration.
Regular inspection allows you to determine the cleaning schedule best suited
to your home’s operating conditions.
The first electronic air cleaning of your
home may collect more particles over a
shorter period than will be normal for
future operation.
As your air cleaner collects particles, its
cleaning efficiency will decline which
makes it all the more important to clean
your air cleaner regularly.
At minimum, the prefilter and collection
cells will need to be cleaned two or three
times per year. Ask your dealer about the
installation of a Bryant thermostat
which has a “Clean Filter” capability to
remind homeowners to check/clean
their air cleaner.
CLEANING PROCEDURES
Cleaning your cells in the dishwasher is
not encouraged by the manufacturer
since many of the captured particles can
stain the inside of your appliance. Dishwasher cleaning is solely at the discretion of the equipment owner.
THERE MAY BE MORE
1. Turn off electrical supply to the furnace or fan coil.
2. Swing door handle on air cleaner
away from cabinet.
3. Remove door of air cleaner by gently pulling out and down on door
handle.
4. Remove cells from air cleaner cabinet by grasping handle of front cell
and slowly pulling cell out until entire front cell is out of cabinet. Support cell with other hand as it is
pulled out of cabinet. DO NOT PULL
CELLS OUT QUICKLY since front
cell is connected to back cell and cells
will be damaged if dropped. Note location of cell handle for easy reinstallation after cleaning.
5. Tilt front cell to 1 side to disengage
clips connecting front cell to back
cell. Set front cell aside.
6. Remove back cell by grasping handle and slowly pulling out of cabinet.
7. Carry cells by their handles to the
cleaning area.
8. Remove prefilters from each cell.
9. Clean the prefilter. Use a vacuum
cleaner and soft brush attachment to
remove accumulations of dust and
lint. If further cleaning is required,
wash the prefilter with mild detergent and water (or use pressurized
spray from a garden hose or coin-operated carwash sprayer). Rinse.
Then drain excess water from the
prefilter. Thorough drying is optional.
10. T o clean the collector cells, fill a large
container with hot water. Add onehalf cup of mild detergent for every
10 gallons of water used. Submerge
the cells in the soapy solution and allow to soak for 20 minutes. Rinse
with a garden hose or soak in clean,
hot water for 10 minutes. Allow excess water to drain from the cells. Allow cells to dry thoroughly.
11. Inspect the cells. Check for broken
wires or bent collector plates. If
damage is suspected, contact your
servicing dealer for immediate repair.
12. Carry cells by handles back to air
cleaner cabinet. Reattach prefilters
to each cell.
13. Position both cells so that each handle is closest to the equipment owner
and so furnace arrow on each cell
points towards the furnace.
14. Either cell can be installed as the
front or back cell. Hold cell handle
with one hand and bottom of cell
with other hand and gently slide cell
