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 develop-
mentandtheculminationofmany years
of experience from one of the most rep-
utable manufacturers of comfort sys-
tems.
Your new unit is among the most
energy-efficient and reliable air filtra-
tion products available today.To assure
its dependability, spend just a few min-
utes with this booklet now. Learn about
the operation of your electronic air
cleaner and the small amount of mainte-
nanceittakestokeepitoperatingatpeak
efficiency.
With minimal care, your electronic air
cleaner will provide you and your fam-
ily with clean, healthy, and comfortable
air—from season to season, and year to
year.
YOUR ELECTRONIC
AIR CLEANING UNIT
YOUR INDOOR AIR POLLUTION
SOLUTION
The highest value of clean air is in its
contributiontothe good healthandcom-
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.
Airbornepollutantscommonlyfoundin
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-
ducepositiveionsthatgiveairbornepar-
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 liv-
ing 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 air-
flow 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. Setthetemperaturecontrolselectoron
your indoor thermostat. Choose a set-
tingabovecurrentroomtemperatureif
heating is required. Set the tempera-
ture control selector below room tem-
perature if cooling is needed.
2. SettheFAN mode on thethermostat.
When set to AUTO, the air cleaner
and system blower will run only
while the thermostat operates the
heating or cooling equipment.When
the FAN mode is set at the ON posi-
tion, 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: The operation light indicates
that power is available to the cells. It
does not indicate that power is available
to the EAC.
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.
ELECTRICAL POWER
DISCONNECT
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,
or turn the power off according to the
manufacturer’s specifications.
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,considertheseimportantsafety
precautions:
• DISCONNECT ALL ELECTRICAL
POWER TO THE AIR CLEANER
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.

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 deter-
gent and water (or use pressurized
sprayfromagardenhoseorcoin-op-
erated carwash sprayer). Rinse.
Then drain excess water from the
prefilter. Thorough drying is op-
tional.
10. Tocleanthecollectorcells, fillalarge
container with hot water. Add one-
half cup of mild detergent for every
10 gallons of water used. Submerge
the cells in the soapy solution and al-
low to soak for 20 minutes. Rinse
with a garden hose or soak in clean,
hot water for 10 minutes. Allow ex-
cess water to drain from the cells.Al-
low 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 re-
pair.

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
