These instructions cover the installation, operation and
maintenance of an EACB Electronic Air Cleaner
This electronic air cleaner is technically known as a two-stage
electrostatic precipitator. The air cleaner is designed to remove
airborne particulates, including dust, dirt, smoke, pollen, virus,
spores, bacteria and mold, from indoor air Air movement through
the unit is provided by the heating, air conditioning or ventilating
system blower As dirty air enters the air cleaner, the air passes
through a metal mesh prefilter The prefilter prevents lint, pet hair
and other large particulates from entering the air cleaner It is
important that these filters be in place to prevent excessive dirt
loading of the air cleaner collector cells These filters extend the
time between maintenance of the air cleaner collector cells_ This
allows the ionizing-collector cells to provide clean air for a longer
period between washings The prefiltered air then passes through a
two-stage Electronic Air Cleaner In the first stage, all airborne
particulate, even _bmic'ron size, are electronically charged
(,positive) as they pass through the ionizer The ionizer field is set
up by a corona discharge emanating from the fine, tightly strung
wires suspended between two adjacent flat plates In the second
stage, the charged particulate passes through an intense electrical
field established between alternately charged and grounded parallel
collector plates. Here, the positively charged particulate is attracted
to the negatively ground plates and removed from the air stream

sensor and safety interlock switch_ Apower cord at the rear of the
tray allows the unit to be connected to a standard 120-v or 240-v
outlet (see voltage of your EACB unit) A wiring compartment is

providedattherearofthe tray allowing the option to permanently
wire the unit directly to a furnace control,
AirFlow Sensor (AFS)
This part controls the operation of the unit by sensing the
movement of air within the duct This helps to reduce power usage.
How to Identify Which Air Cleamer Model You Own
The model number and serial number for your Electronic Air
Cleaner can be found on the data label located on the inside of the
access door
Facts You Should Know About Your New
Electronic Air Cleaner
Dus_g and "Whi_usW
Your new Electronic Air Cleaner will efficiently clean and filter
your household air. Unfortunately, it will not eliminate the need for
regular dusting of your furniture and belongings. Due to the design
of all duct-mounted air cleaners, they can only clean the air that
reaches tbe air cleaner.. Therefore, if the particulates are not being
carried to the air cleaner in the air _tream, the air cleaner cannot
remove them from your home Occasionally a "white dust" may be
noticed in bedrooms or newly furnished rooms. This is mainly
composed of lint which, because it is heavier than other
particulates, settles before it reaches your unit_ This "white dust" is
not mixed with airborne dirt particles, therefore, it is clean and has
no staining or soiling properties.. However, running the furnace
blower continuously, day and night, will help reduce this from
occurring.
Ozone
Under normal operating conditions all Electronic Air Cleaners
produce minute quantities of ozone as an incidental by-product._ In
fact, all electronic products, such as televisions, cordless phones
and refrigerators, produce some amount of ozone. The average
homeowner can detect the smell of ozone concentrations as low as
25 to 100 ppb (parts per billion) The design of this unit hag been
tested and ozone production is approximately half of the published
permias_le limits established by the Environmental Protection
Agency.. These limits recommend that the concentration of indoor
ozone not exceed 50 ppb.. Ozone is not harmful in these
concentrations. In fact, the ozone level in major cities can
sometimes reach as high as 100 ppb on a summer day. The
addition of optional charcoal after-filters can help reduce this
Normally, a new unit will produce more ozone than one that has
been in operation for several weeks.. This is due to sharp comers or
manufacturing burrs on the ionizing-conecting ceil(s) and is
normal. As the Electronic Air Cleaner arcs _md zaps, the voltage is
vaporizing these areas and tends to round them off This is part of
the breaking-in period of ownership and the issue is
self-correcting Also, high-altitude locations can be more
susceptible to noticing the presence of ozone. An
ionizing-collecting cell that has been damaged or bent (the
designed Macing between electrically charged and ground
components has been decreased) may also produce an abnormal
amount of ozone_
Hew the .'MrFlow Sensor (AFS) Works
Electronic AFS (see Fig 3) was designed to provide an efficient
and reliable method of controlling the operation of the air cleaner
when the dealer is unable to wire the unit directly into the furnace
blower. The electronic AFS is now integrated into the power
supply circuitry and utilizes a thermistor that heals up to
approximately 130°F (54_C). The AFS then stabilizes at this
temperature and when the furnace blower tams on and air flows
through the ductwork, the same vacuum effect pulls cooler air over
the hot surface. This air movement cools down the thermistor and
this cooling down effect allows the electronic AFS to understand
that the furnace blower is moving air and the Electronic Air
Cleaner must turn on to provide air cleaning
Fig. 3 - AJrflow Sensor
A05029
If the air cleaner is installed in a location that is dusty and dirty, the
sensor on the AFS can become coated with dirt and lint.. This
coating am insulate the AFS and keep it from operating properly
To clean the thermistor, tam unit off and allow thermistor to cool, 1

Planning the Installation
Application
Air cleaners are used in Iorced air heating cooling and ventilating
systems The air cleaner should be installed in the system so that all
the system air is circulated through the air cleaner The air cleaner
will only remove the airborne contaminants delivered to it,
Maximum performance is obtained when the system blower is set
for continuous operation
Installation Requirements
The best location for the air cleaner is in the return air duct next to
the blower compartment, In this location, the blower molor and
cooling coils will be kept clean.
UNIT OPERATION AND SAFETY HAZARD
Failure to follow this caution may result in reduced airflow
and potential operating problems
a o not install the air cleaner in the diseharge air duct
Before instaning the air cleaner, consider the application and type
of e VAC sy_em present, See Fig, 7 for the most common types, If
a transition between the ductwork and air cleaner is required, refer
to section entitled Transitions and Fig 5,, The unit must be readily
access_le for periodic inspection and cleaning of the prefilters and
electronic cells to maintain maximum efficiency and trouble-free
operation,
Air Conditioning
The air cleaner should be installed upstream of the cooling coil
This will keep the coil clean and reduce air conditioning coil
maintenance Improved cooling efficiency is the result and directly
affects energy costs A clean coil will reduce utility costs.
Humidifiers
An evaporative humidifier can be mounted upstream of the air
ctcanem, It is best to install an atomizing humidifier downstream of
the air cleaner because hard water salt deposiL_ and water droplets
may damage the air cleaner

COMMONLY ASKED QUESTIONS
Qo WKy Isn't my Bl_ cqtDaH` cQEnlag my Blv?
A. The air cleaner is most likely working just like it was designed.
However, many factors can affect the performance of the unit_ Are
cold alr registers located in the ceiling? If so, it will be difficult for
the airflow to carry heavier particulates to the air cleaner If the dirt
chrw'v_r/,_'_lorqtoaru_:t_'_rarp _tt_ _OoAm
both the Red and Green lights illuminated? If not, then the unit
may be in need of servicing. Contact your local HVAC dealer for
asslstance_
Qo It s_n't eqtDalng my I_ tKHZI_ I zUnt It,tit WIrq3teEn I
do?
A. We recommend that you run the blower continuously so that
the air movement will carry the dirt to the air cle,'mer.
Unfortunately, there will _flways be some dirt that is left behind on
the appliances, furniture, etc Regular dusting is recommended to
stir up these pockets of dust so that they can enter the alrstrcam and
be removed by the Electronic Air Cleaner
n,, t hen Iturn on my Eh:ctronic Air Cleanerlthe lights come
on for a couple of seconds and then turn off., The air cleaner
Isn't zRrklng!
AThe air cleaner is fine as long as both the Red and Green lights
are coming on. Try turning the HVAC blower OFF and then
turning the Electronic Air Cleaner on This should solve the
problem.
nt hat is rite zapping noise I am hearing from my unit?
Should I be concerned?
A. The zapping or popping noise that you are hearing is the sound
of larger particles being vaporized by the ionizing-collector cell.
This is normal and is no cause for alarm.. As your HVAC system
blower moves the air through the dnctwork and allows the
Electronic Air Cleaner to clean the air, the noise will diminish
However, there will always be instancea when larger particles enter
the ionizing-collector cell
nShould I hear thL_ zapping noise all the time?
A._ All Electronic Air Cleaners will occasionally zap or pop as
larger particles pass through the ionizing-collector cells. However,
if the sound is constant or is repetitive in nature, then alarge
particle may have become lodged in the ionizing-collector cells
and they may require cleaning If cleaning the ionizing-collector
cells does not stop the noise and there are no large particles trapped
in the ionizing-collector cells, then the cause could be a
bruken!toose ionizing wire, bent collector plate or other mechanica!
reason. Please contact your local HVAC dealer for a._sistance..
n o t hat if Ino longer' hear any popping or zapping noises
coming from my unit? Is it still denning the air"?
A. If the zapping noises stop and the air cleaner is not in need of
servicing, then one of two situations has occurred.. Flint, the
Electronic Air Cleaner has successfully removed all larger particles
from the air and is cleaning microscopic particles which do not
cause the zapping noise Second, the blower and/or HVAC system
is not running and air is not flowing through the ductwork. The
Electronic Air Cleaner cannot remove particles if the air stream is
not moving.
n. I lost power to my home during a storm,, Should I worry
about the Electronic Air Cleaner'?
A. The most common problem associated with power outages is
the unit will not turn on properly after power is restored. If the Red
and Green light come on for a couple of seconds and then go off,
the unit is OK gust turn the HVAC blower off, turn the unit ON
and then turn the blower back on If the Red and/or Green light
does NOT come on after a storm, the power supply in the
Electronic Air Cleaner may be short circuited. Contact a local
HVAC contractor for further information_
n. My installer told me to keep the H s AC system blower
running _KHtlmH l_t IdRn't Z13at tRlncrHyHmy SIGH"
bill, t hatshould I do?
A.. It is recommended that you keep your HVAC sy_em blower
running all the time to achieve the maximum air cleaning
efficiency. This will allow the Electronic Air Cleaner to do what it
is designed to do, which is clean the air. Remember that if the air
does not reach the air cleaner, it cannot be cleaned On average,
your Electronic Air Cleaner will use the same amount of electricity
as a55 watt light bulb. The energy usage of the HVAC system
blower will depend on the age of your system, energy costs in your
regional location and other variables The best solution is to try
running the HVAC system blower in continuous mode for a month
or two to estimate your annual energy costs and base your final
decision on what you fee! most comfortable with.

Indication of Electrical Trouble
The air cleaner is equipped with a Red CbLL bNbRd fWbD light
for indicating proper unit operation. When the unit is in normal
operation (with the e s AC system fan running, access door in place
and rocker switch in the ON position) and the Red CbLL
bNbRdfWbD light is not lit, the problem is a shorled secondary.
Although failure of the indicating light itself should not be
overlooked, this condition is unusua| and rather remote.
Primary Circuit with Blower Operating
ff there is supply line voltage at the connections and no input
voltage to the power supply, the outage can be located by checking
operation of the safety switch and the interconnecting wiring with a
multimeter Refer to Circuit Diagram, to check operation of the
switches. Following these steps to test for proper operation of the
circuit board and power supply assembly:
1 bnsure that the circuit breaker controlling the furnace
blower is in the ON position and the main fuse is not open.
2The power supply board has a built-in internal fuse to
protect the 24s transformer ft can be checked visually by
inspecting the fuse ff the fine wire inside the fuse is broken,
this indicates a problem in the 24scircuit of the power
supply board.. Do NOT replace this fuse The entire power
supply board must be replaced The purpose of the fuse is
not to protect the power supply board, but to function as a
troubleshooting feature of the product and to protect the
transformer from damage

3. If the fuse is NOT blown, check the ON/OFF _vitches and
safety interlock witch for proper engagement and
operation This can be completed using a volt ohm
millimeter on a scale that will measure ohms as low as 10
If you are using the recommended meter previously
mentioned in this manual, set the meter to read 200 ohm
and proceed with Steps 4 through 6
4Remove the fuse Connect one lead to the test pin located
direclly beside the wire that connects the ON/OFF switch to
the power supply board Connect the other lead to the fuse
connection closest to the front panel,
5 Turn the ON/OFF switch to the ON position and depress
the safety interlock switch The meter should have the
capability of reading levels as low as I 0 ohm
6 If there is no reading on the meter, begin the process of
elimination by disconnecting the wire from the test point
and connecting it to the terminal with the blue wire located
on the safety interlock .switch. Depress the safety interlock
switch lfthe reading on the meter is greater than ]0ohm,
the safety interlock switch is defective and must be replaced.
If the reading on the meter is less than t 0 ohm, the
ON/OFF switch is defective and must be replaced.
Ionizing-Collecting Cell
Secondary Circuit
The cell is electrically energized through a contact terminal located
at the top center of the cell. The ionizing wires and alternating
collector plates are electrically charged while the interleaving plates
are grounded If the space between the charged and grounded
plates is bridged with conductive or semi-conductive materiaI, a
short circuit develops The bridging or short may be caused by
damaged plates, or foreign material lodged between/on the
components.
Since the cell should be periodically removed from the unit to
wash away collected dirt, it is s'uscept_le to physical damage. The
cell also contains the ionizing wires which, due to their function,
have been designed with minimal structural support and are
suscept_le to breakage. However, trouble related to a shorted
collector cell is readily shown by the Red CELL ENERGIZED
light and can be quickly isolated by a simple procedure.
To determine if a short exists in one or both of the collector cells,
tam the Electronic Air Cleaner OFF and remove both electronic
cells from the cabinet. Shut the door and repower the unit. If the
Red CELL ENERGIZED light comes on, an electrical short exists
in one or both of the electronic cells. Replace the cells in the unit,
one at a time, to determine which ceil is shorted Most troubles in
the colt can be visually detected and corrected.
NOTE: The ionizer collector cells ,are not designed for field repair.
Ionizing wires ,and insulators can be field replaced It is not
recommended that you attempt to replace other cell components
(i e Collector plates, end plates, ionizer supports)
Replacing the Ionizing Wires
Ionizing wire breakage is minimal because of the constant tension
design and fixed location of the ionizing wire supports. When an
ionizing wire breaks, the efficiency of the Electronic Air Cleaner
will decrease slightly. However, the unit will continue to operate
with broken ionizing wires as long as the broken wires have not
caused a short circuit of the unit Remove all loose and broken
wires as soon as they are identified. Although the replacement of
the ionizing wires can be attempted by a homeowner, it is
recommend that you should contact a qualified HVAC contractor
for replacement parts and/or servicing.
Wires are supplied in a coiled spring configuration, with aclinch
nut on each end of the wire Replacement requires a pair of needle
nose pliers Exercise caution in removing any broken wires in the
collector cell.. This will prevent accidental shorting of the cell and
reduce the need for further maintenance U_ the following
procedure when replacing an ionizing wire
I. Ensure that alt power to the Electronic Air Cleaner is OFF,
remove the access door and remove the ionizing-collector
cells from the uniL
2 Carefully remove a!l remains of the broken wire
3 Grip the neW wire at each end of the wire with your thumb
and index finger While stretching the wire to approximately
6" (152 ram) _ RnH_GRI kh_Hzl_lq'_l_ UnFRIDEH_FFP
your thumb and index finger.
4 n'laca one end of the wire in the slot of the stainless steel
.support on the collector cell fi'om the front of the cell This
_pport is partially covered by the cell brace in front of the
support
5.. Grip the other end of the ionizing wire with needle nose
pliers and insert the terminated end of the wire into the slot
on the support bar of the opposite end of the collector cell
6. The wire should be tight enough to be self supporting and
remain suspended between the two support slots in the
_pport bar.

of nuisance arcing The homeowner can quickly and easily correct
this condition..
]. Turn the unit OFF Turn off circuit breaker or disconnect the
power cord
2_ Remove the two screws that secure the cover to the power
tray and remove it from the unit (The entire power supply
tray may be removed from the cabinet by removing two
screws from inside cabinet.) Do not lose these ,screws
I

3,, k_cate the jumper terminal (see 12)_ wire support bar with end of the high voltage probe, The
meter reading should be 62 kVDC -2 kVDC

4, With a pair of needle nose pliers, carfia!ly adjust the jumper
settings from HIGH to MED Ensure that the jumper is
firmly seated in the terminal.
5 Replace the power tray cover and secure it with the two
SCrews
6.. Replace the access door and turn the unit ON.
This procedure will slightly reduce the output voltage, minimize
aming, and reduce ozone production.. If the condition does not
improve, repeat the above procedure and move the jumper setting
from MED to L.OW If this does not correct the situation, contact
your local HVAC dealer All Electronic Air Cleanem are produced
at the factory with the jumpers set in the HIGH position However,
the output voltage may be lowered in any situation where the unit
is arcing excessively or there is excessive ozone production..
Checking the Power Supply
If the output light remains out with the collector cells removed
from the cabinet, the power supply is defective. Specific problems
on the power tray assembly can be isolated by using a multimeter
and high voltage probe to check the output voltages. To check the
secondary circuit, a high voltage meter is required.. See the section
entitled Recommended Service Tools To check for proper
operation, it is imperative that the procedure be followed as
outlined below:
LMake sure the furnace blower is operating, the control
switch is on, and input voltage is correct..
2. Remove front door assembly panel
3.. Remove power pack access cover
4.. Check tile high voltage contact board assembly(s) for
damage or carbon tracking.
NOTE: The cell contacts should be visually checked for
corrosion, excessive dirt build up, and electrical are tracking
(carbon path from stainless steel spring to grounded metal) Clean
or replace as required.
5.. Make connections from the high voltage probe to the
