YOUR ELECTRONIC
AIR CLEANING UNIT
YOUR INDOOR AIR POLLUTION
SOLUTION
The highest value of clean air is in its
contributiontothegood health andcom-
fort of you and your family. Additional
benefits include potential savings in
homeheating,cooling,andmaintenance
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.
Airbornepollutantscommonlyfound in
thehouseholdarelint,dust,ash,pethair
and dander, pollen, fungus, spores, bac-
teria, viruses, cooking grease, and pos-
sibly tobacco smoke odors.
By ridding your home of most of these
pollutants,thewhole familycan breathe
fresher, safer air. Moreover, family
members suffering from hay fever,
asthma, or allergies may find relief,
since electronic filtering removes many
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.
Ifyourhomeisequippedwithcentralair
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.
HOWYOUR AIR CLEANER
WORKS
Contaminatedairenterstheprefilter(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 pro-
ducepositiveions that giveairborne par-
ticles 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.)

OPERATINGYOUR
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 recom-
mendations 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-airandreturn-airgrillesshould
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.
START-UP PROCEDURES
1. Ensure the air cleaner’s door handle
is engaged, latched, and power
switch turned ON, powering unit.
2. Setthetemperaturecontrolselectoron
your indoor thermostat. Choose a set-
tingabovecurrentroomtemperatureif
heating is required. Set the tempera-
ture control selector below room
temperature if cooling is needed.
3. SettheFANmodeonthethermostat.
When set to AUTO, the air cleaner
and system blower will run only
while the thermostat operates the
heatingorcoolingequipment.When
the FAN 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.
4. Select operating mode of HEAT,
COOL, or AUTO.
NOTE: The operation light (green)
indicates that power is available to the
electronic air cleaner. It does not indi-
cate that power is available to the cells.
NOTE: An occasional arcing (snap-
ping) noise is normal during the opera-
tion of your air cleaner. Continuous
arcing, however, indicates that cleaning
is required. Refer to directions on clean-
ing your electronic air cleaner.
PERFORMING ROUTINE
MAINTENANCE
With the proper maintenance and care,
your electronic air cleaner will operate
economically and dependably. Mainte-
nance can be accomplished easily by
referring to the following directions.
However, before performing any main-
tenance,considertheseimportant safety
precautions:
• DISCONNECT ALL ELECTRICAL
POWER TO THE AIR CLEANER
AND FURNACE OR AIR HANDLER
BEFORE PERFORMINGANY SER-
VICE OR MAINTENANCE.
NOTE: THERE MAY BE MORE
THAN 1 ELECTRICAL DISCON-
NECT SWITCH.
The prefilter and ionizer/collector cells
should be checked for dirt regularly.
Accumulated dirt needs to be removed
from these components to maintain effi-
cient air filtration.
Regular inspection allows you to deter-
mine 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.
Atminimum,theprefilterandcollection
cellswillneedto be cleaned 4 or 6 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. After about 400 hr of
operation, the thermostat will display a
“Clean Filter” icon when it is time to
clean the filter. (See Fig. 3.)

CLEANING PROCEDURES
Regular washing is necessary to insure
proper performance.A thorough
washing once every 2–3 months will
be adequate for most installations.
More frequent washing (once a month)
may be necessary on some installations
(new homes for example) where there
is new carpeting, plaster dust, or there
is above normal cigarette smoke.
(See Fig. 4.)
1. To remove the cells and prefilter
a. PushtheaircleanerswitchtoOFF.
Wait 15 seconds. Open the access
door.
b. Carefully remove the cells and
prefilter, and set aside.
c. Avoid damage to the cell plates
and ionizing wires.

2. To wash the cells in a tub
a. Place enough hot water in a utility
tub to cover the cell. Electronic air
cleaner concentrate solution (Part
No. P902-2001) is recommended.
(The solution is available from
your dealer through our Replace-
ment Components Division.)As
an alternative, 2 to 4 oz of auto-
matic dishwasher detergent (not
laundry detergent) can be used.
b. Allow the cell to soak for 30 min-
utes.Agitate it up and down in the
solution until it appears clean,
then remove.
c. Repeat with the second cell.
d. Agitate the prefilter up and down
in the solution until they appear
clean.
e. With a hose, rinse the cells and
prefilter. The hose should be held
about 10 in. from the cell plates
and at a slight angle for better
cleaning results. The cell frame
should be thoroughly rinsed along
the edges to dislodge any trapped
lint or dirt. Carefully wipe a damp
cloth or sandpaper (not emery
cloth) along the ionizing wires.
f. Stand the cells and prefilter up to
drain. Let dry for 2 hr.
We do not recommend washing the
electronic air cleaner cells in the dish-
washer.
Not only can the collector
plates and ionizing wires be easily
damaged, but dirt from the cells and
prefilter can permanently stain plastic
dishwasher linings.
3. To replace the cells and prefilter
a. Replace the prefilter and cells in
the cabinet. Check that the arrow
on the cells points in the same
direction as the air flows through
the duct. The arrow should
be pointing to the air handler or
furnace. (If you have to force
it past the positioning screw
on the bottom, it is probably in
a wrong position.)
b. Reposition the access door
(engage the tips on the lower edge
of the door into the slots in the
cabinet). Carefully close the door.
c. Turn the air cleaner switch to ON.
OPERATION CHECKLIST
• Check
thesetting
on your
indoor
thermo-
stat. The
FAN
should be
set at ON
position
for contin-
uous blower and electronic air cleaner
operations, or AUTO if you wish the
blower and air cleaner to function only
when heating or cooling is required.
• Check the power switch on your elec-
tronic air cleaner. Be sure it is ON and
the power indicator lamps (green and
red) are glowing.
• Check the main power disconnect
switch. Verify that the circuit breakers
are ON or that fuses have not blown. If
youmustreset breakersorreplacefuses,
do so only once. Contact your servicing
dealer for assistance if breakers trip or
fuses blow a second time.
• Check electronic air cleaner compo-
nents. Check for proper orientation of
the prefilter and ionizer/collector cells.
Theprefiltermustbeon the farthestside
from the furnace. Arrows stamped on
the sides of the cells must point in the
direction of the furnace. The prefilter
and cells must be clean and dry.
• Check for sufficient airflow. Check
for blocked return-air or supply-air
grilles. Be sure grilles are open and
unobstructed.
If your comfort system still fails to oper-
ate, contact your servicing dealer for
troubleshooting and repairs. Specify
your apparent problem, and state the
model and serial numbers of your
equipment.
With this information, your dealer may
be able to offer helpful suggestions over
thephone,orsavevaluabletimethrough
knowledgeable preparation for the ser-
vice call.
REGULAR DEALER
MAINTENANCE
In addition to the routine maintenance
that you perform, your electronic air
cleaner should be inspected regularly by
a properly trained service technician.
Theinspection(preferablyeachyear,but
at least every other year) should include
the following:
• Routine inspection of ionizer wires.
Service should include realignment or
replacement as required.
• A check of all electrical wiring and
connections.
• Operational check of the complete
comfort system to determine actual
working condition. Necessary repair
and/or adjustment should be performed
at this time.
Your servicing dealer may offer an
economical service contract that covers
seasonal inspections.Ask for further
details.
Record the model and serial numbers
of your new electronic air cleaner in
the spaces provided on page 8. This
information, along with the other ready-
reference facts requested below, may be
required if you should ever need
information or service.
