INTRODUCTION

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

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

A05029

Fig. 3 - AJrflow Sensor

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 then take a cotton swab dipped in rubbing alcohol and carefully insert it into the hole tocaled on the right hand side of the power S[2dqt_sl-p E_ (whhn ll2_ing thHunit)ThHho_liS 3/I6" (5 p p ) in diameter and is located on the front of the power tray assembly.. Carefully twirl the cotton swab between your fingers, making sore the tip is lightly in contact with the coated bead, cleaning this

coating from the thermistor If airflow sensor is bypa_ed on the circuit board, the Air Cleaner will run at all times when power is

applied (see Fig 4),

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

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 I turn on my Eh:ctronic Air Cleanerlthe lights come on for a couple of seconds and then turn off., The air cleaner

Isn't zRrklng! A The 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.

n t 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

n Should 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 a large

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 I no 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 I dRn'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 a 55 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.

MAINTENANCE OF CELLS

Washing Ceils and Prefilters

Regular washing is necessary to ensure proper performance (see Fig 11). A thorough washing once every two months wilt be

adequate for most installations More frequent washing (once a month) may be nece_ary on some installations (new homes for

example) where there is new carpeting, plaster dust, or excessive cigarette smoke

To remove cells and prefilter

1. Push air cleaner switch to the OFF position Wait 15 seconds. Open door access panel.

2. Carefully remove cells and prefilter(s) and set aside in a safe

place,

3 Do not drop the ionizing-collector cell This could cause

damage to the cell plates or ionizing wires and cause excessive arcing and noise,

To wash cells and prefilter(s)

To wash cells and prefilter(s) We suggest that you follow the instructions below to properly and thoroughly clean your collector cells

i Place enough hot water in a utility tub to cover the first ceil.

Dissolve 2 to 4 oz of granulated automatic dishwasher detergent (not laundry detergent) in the water.

2 Allow the cell to soak for 30 minutes Agitate it up and

down in the solution until it appears clean and remove

3 Repeat with second cell. 4 Agitate the prefitters up and down in the solution until they

appear clean.

5 With a hose, rinse the cells and prefilters The hose should

be heCI I'_RU\M0 " (254 pp) fzRp _ FetiDp(_ El_d IJAiD slight angle for better cleaning results Be careful not to spray the ionizing wires directly with the hose The water pressure can cause the wire to snap and break, The ceil

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,,

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.

2 The power supply board has a built-in internal fuse to

protect the 24 s 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 24s circuit 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 1 0 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

4 Remove 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 ] 0 ohm, 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 a clinch

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.

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:

L Make 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 mu(tM_14lq" In IyocRrGD_cHwl3/€ WH RS_'VmDml;9 ThH meter should be set for reading DC voltage on the 20 volt

full scale

6.. Attach the high voltage probe ground lead to the cabinet. While depressing the safety switch lever, touch the ionizer

Z tf no voltage is measured, remove the first cell ,'rod check

the second cell The meter should read 6.2 kVDC - .2 kVDC

8. If proper voltage is measured, the first cell is shorted

9. If no voltage is present, remove the second cell Ins-tall cell

number one and me,_sure voltage as described above. If voltage is present, the second cell, which is now out of the

cabinet, is shorted

I0. If no voltage is present, remove both cells and measure the

power supply output. Wlaile drpressing the safety switch, touch the end of the high voltage probe (see Cig 13) to either the front or rear contact board assembly The meter should read 62 kVDC or higher

11 If no voltage is present, check the power supply.. Set the

multimeter for reading AC voltage at 200 volt full scale and attach meter test leads

12 While depressing the safety lever, touch the two transformer

output lead junctions to the power supply board with the meter leads and read the meter.
