INTRODUCTION

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 its 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 submicron 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 isattracted to the negatively ground plates and removed from the air
stream.

UNIT SPECIFICATIONS

This air cleaner is easy to install, operate and maintain. Its basic components
arethe:

Cabinet
Mounts to existing ductwork; houses the ionizing-collecting cells and
prefilters.

Ionizing-Collector Cells

Collect the dust, dirt and other particulates in the air. They contain the
ionizing and collecting sections as described on page 2. The cells must be

installed with ionizing wires on the air intake side. A spring contact is located
on the top of each cell and must be in position to make contact with the
contact board assemblies on the bottom of the oower tray assembly.

Prefilters

Trap large particulates before it enters the ionizing-collector cells.

Power Tray Assem bly

Contains the indicating light, solid state power supply, contact boards and
electrical controls including ON/OFF switch and safety interlock switch. A

power cord at the rear of the tray allows the unit to be connected to a

standard 120V outlet. A wiring compartment is provided at the rear of the tray
allowing the option to permanently wire the unit directly to a fumace control.

Air Flow Sensor (AFS)

Installed on certain models, this part controls the operation of the unit by

sensing the movement of air within the duct. This helps to reduce power
usage and prevents the possible buildup of ozone within the duct.

Howto Identify Which Air Cleaner 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. This serial
number will be a ten (10) digit number.

FACTS YOU SHOULD KNOW ABOUT YOUR NEW

ELECTRONIC AIR CLEANER

Dusting and "White Dust"

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 the air cleaner. Therefore, if the

particulates are not being carried to the air cleaner in the air stream, 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 has been tested and ozone production is approximately half of the

published permissible 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 tact, 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 corners or manufacturing
burrs on the ionizing-collecting cell(s) and is normal. As the Electronic Air

Cleaner arcs and 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
spacing between electrically charged and ground components has been
decreased) may also produce an abnormal amount of ozone.

How the Air Flow Sensor Works (available on specific models)

The electronic AFS 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 utilizes a
thermistor that heats up to approximately 130°E The AFS then stabilizes at

this temperature and when the furnace blower turns 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.

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 can insulate the

AFS and keep it from operating properly. To clean the thermistor, take a
cotton swab dipped in rubbing alcohol and carefully insert it into the hole
located on the right hand side of the power pack assembly (when facing the

unit). The hole is 3/16" in diameter and is located on the front of the power

tray assembly. Carefully twirl the cotton swab between your fingers, making
sure the tip is lightly in contact with the grey disc, cleaning this coating from

thethermistor. T.E.___

1. Make sure the furnace blower is not operating, the rocker

is OFF and the circuit breaker is turned OFF or cord is
disconnected.

4. Locate the AFS. It is a circuit board with a small grey_q
connected to the circuit board by two(2) silver .wi'res (sir_ to

Figure 1). Carefully bend the thermistor so that it is Iocat, In the

center of the opening and approximately 1/8" from the inside edge
of the power pack assembly.

5. Reinstall the power tray assembly end access door.

i

Hiqh Altitude Operation

Because the air is less dense at higher altitudes, there is a possibility of
nuisance arcing. The homeowner can quickly and easily correct this

condition.

1. TurntheunitOFE Disconnectcordorturnoffcircuitbreaker.

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 the cabinet.) Do

not lose these screws.

3. Locatethejumperterminal (seefigure2).

4. With a pair of needle nose pliers, carefully 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. Replacethe access door and turn the unit ON.

This procedure will slightly reduce the output voltage, minimize arcing and

reduce ozone production. If the condition does not improve, repeat the
above procedure and move the jumper setting from MED to LOW. If this

does not correct the situation, contact your local HVAC dealer.

All Electronic Air Cleaners 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.

Figure 2

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 recommended that a qualified HVAC contractor be

contacted 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.

Usethe following procedure when replacing an ionizing wire.

1. Ensure that all power to the Electronic Air Cleaner is OFF, remove the
access door and remove the ionizing-collector cells from the unit.

2. Carefully remove all remains ofthe 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" allow one end of

the wire to uncoil between your thumb and index finger.

4. Place one end of the wire in the slot of the stainless steel support on
the collector cell from the front of the cell. This support 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 support bar.

Common Questions and Answers

Q.

A.

Why isn't my' air cleaner cleaning my air?
The air cleaner is most likely working just like it was designed.

However, many factors can affect the performance of the unit. Are cold air
registers located in the ceiling? If so, it will be difficult for the air flow to

carryheavierparticulatestotheaircleaner.lfthedirtdoesn_getto the air

cleaner, it can't be removed from the air. Are both the Red and Green lights
illuminated? If not, then the unit may be in need of servicing. Contact your

local HVAC dealer for assistance.

e.

A.

It still isn't cleaning my air the way I want it to. What can Ido?

We recommend that you run the blower continuously so that the air

movement will carry the dirt to the air cleaner. Unfortunately, there will

always 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 airstream and be removed by the Electronic Air Cleaner.

Q. When I turn on my Electronic Air Cleaner, the lights come on for a couple

of seconds and then turn off. The air cleaner isnhtworking!

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.

Q. What is the zapping noise I'm 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 ductwork and allows the Electronic Air Cleaner to clean the

air, the noise will diminish. However, there will always be instances when
larger particles enter the ionizing-collector cell.

Q. Should I hear this 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 broken/loose ionizing wire, bent collector plate or
other mechanical reason. Please contact your local HVAC dealer for
assistance.

8

Q. What if I no longer hear any popping or zapping noises coming from

my unit? Is it still cleaning 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. First, 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.

Q. 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. Just 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.

Q. My installer told me to keep my HVAC system blower running all the

time, but I don't want to increase my power bill. What should I do?

A. It is recommended that you keep your HVAC system blower running

all the time to achieve the maximum air cleanJng 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 55W 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 feel most comfortable with.

MAINTENANCE OF YOUR ELECTRONIC AIR CLEANER

_WARNING :Handle ionizing-collector cells with care as plates

,can be sharp and cause injury if not handled properly. __.

WASHING CELLS AND PREFILTERS

Regular washing is necessary to ensure proper performance. A thorough

washing once every two 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 excessive cigarette smoke (Figure 3).

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.

10

Towashcells and prefilter(s)

We suggest that you follow the instructions below to properly and

thoroughly clean your collector cells.

1. Place enough hot water in a utility tub to cover the first cell. 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 prefilters up and down in the solution until they appear
clean.

5. With a hose, rinse the cells and prefilters. The hose should be held
about 10" from the cell plates and at a 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
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.

6. Stand cells and prefilters up to drain. Let dry two hours. You may
experience a slight discoloration of the aluminum collector cells after
washing. This is a normal chemical reaction and will not harm your

unit or affect its performance.

To replace cells in air cleaner

1. Replace prefilter and cells in cabinet. Check that arrow on cells points
in same direction as air flows through the duct. (If you have to force it
past the positioning screw on bottom, it is probably in the wrong
position.)

2. Replace access door (engage tabs on lower edge of door into slots in
cabinet). Carefully close door.

3. Turn air cleaner switch to ON.

PLANNING THE INSTALLATION

A_ation

The air cleaners are used in forced 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. Inthis location, the blower motor and cooling coils will be kept clean.

DO NOT INSTALL THE AIR CLEANER

IN THE DISCHARGE AIR DUCT.

Before installing the air cleaner, consider the application and type of HVAC system
present. Refer to the section entitled Typical Mounting Positions,

for the most common types. If a transition between the ductwork and air cleaner is

required, refer to section entitled Transitions. The unit must be readily accessible

for periodic inspection and cleaning of the prefilters and electronic cells to maintain

maximum efficiency and trouble-free operation.

Air Conditioninq
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. If the air cleaner is downstream of the cooling coil, condensation will

form on the cooled collector plates when the air conditioner cycles. This will allow
water droplets to form on the collector plates and cause nuisance arcing. Arcing will

reduce air cleaner efficiency and reduce the life of the high voltage power supply.

Humidifiers

An evaporative humidifiercan be mounted upstream of the air cleaner. It is best to
install an atomizing humidifier downstream of the air cleaner because hard water
salt deposits and water droplets may damage the air cleaner. If an atomizing
humidifier must be mounted upstream of the air cleaner:

1. Mount itas far upstream as possible. (Recommended at least 6 feet.)

2. Install a standard disposable furnace filter between the humidifier and
the air cleaner to trap water droplets and hard water salts.

3.Clean the air cleaner more frequently to prevent a hard water salt

buildup.

Outdoor Air

When outdoor air isadded to the returnair duct, sufficient heat should be added to

maintain the return airtemperature at 40°F (4°C) minimum. Lower temperatures can
cause ionizer wire failure.

17

Atomizincj Humidifiers

If an atomizing humidifier is installed, it must be mounted downstream of

the air cleaner•

1. Mount the humidifier as far downstream as possible, it is recommended a
distance of at least 10 feet to reduce the possibility of excessive arcing

as water droplets pass through the Electronic Air Cleaner.

2. Install a standard disposable furnace filter between the humidifier and
the air cleaner to trap water droplets and hard water deposits.

3. Clean the air cleaner more frequently to prevent a hard water buildup•

Sheet Metal Installation
The Electronic Air Cleaner is adaptable to all new or existing residential
forced air furnace and cooling systems.

Transitions
If the air duct does not fit the air cleaner cabinet opening, gradual transitions
are recommended to reduce air turbulence through the air cleaner and

maximize efficiency. Not more than 20 °

(about 4" per running foot) of expansion

should be used on each side of the
transition fitting (Figure 4).

Outdoor Air
When outdoor air is added to the return air

duct, sufficient heat should be added to
maintain the return air temperature at 40°F

(4°C) minimum. Lower temperatures can

cause ionizer wire failure.

Fu._

_--4

Turnincj Vanes

If the air cleaner is installed adjacent to a
90 ° duct elbow, add turning vanes inside
the duct to improve air distribution across
the face of the air cleaner (Figure 5).

Failure to follow the recommendation can
reduce the efficiency of the Electronic Air

Cleaner.

SELECT LOCATION FOR AIR CLEANER

Remember to select a location that is readily accessible for periodic
inspection and cleaning of this air cleaner. Allow a minimum of 24"

clearance in front and 12" clearance above the air cleaner for component

removal and service space. For complete dimensions required refer to the
section entitled UNIT DIMENSIONS.

DIRECTION OF AIR FLOW THROUGH THE AIR CLEANER
This air cleaner is set up for left to right air flow when you are facing the

access door.

For right to left air flow, follow these directions:

1. Remove the prefilter(s) and cells from the
cabinet. A plastic positioning spacer is

located inside the bottom of the cabinet.

This spacer is secured to the cabinet using

INSTALLATION

!. CAUTION: Only a trained experienced serviceman should

_all this electronic air cleaner. The power supply should be

'_removed before installation. To remove the power supply, remove
I the two (2) screws (See Figure 7) in the top front of the cabinet.

] Remember to keep this hardware for reinstallation of the power

supply when the air cleaner installation is complete. A thorough

I checkout of the unit installation should be completed before unit
! operation.

PHYSICAL INSTALLATION OF THE AIR CLEANER

This Electronic Air Cleaner can be installed in any position, except with the
access door facing down. The section entitled TYPICAL MOUNTING
POSITIONS show examples of proper air cleaner mounting with a variety of

furnace installations.

Prior to installing this product...

1. Read rules and instructions carefully for safe operation. Failure to follow
them could damage the product or cause a hazardous condition.

2, Check the ratings given on the product to make sure it is suitable for your

application.

3. Select a location for the air cleaner.

4. Remove the old furnace filter and discard.

5. The air cleaner cannot remove existing dirt from the blower and ducts.
Clean the area thoroughly before you begin.

6. Remove unit access panel, and slide the prefilters and ionizing-collecting
ceils out of the cabinet. Place them safely aside with the warranty and

registration card.
NOTE: The following is a typical installation of the air cleaner on a

highboy furnace. You may have to alter the installation to fit your
particular application.

I

,

,

Locate the cabinet in the cold air return duct so that all of the return air

flows through the unit (Figure 6). If the furnace and air cleaner openings

are different, use a transition (Figure 4).

Mounting holes are provided for

ductwork attachment (Figure 7). The

.140" holes are sized for #8 sheet
metal screws, or 1/8" rivets. If the

adjoining ductwork is flanged, install
the screws so that the screw heads

are inside the cabinet. This will prevent
damage to the prefilters and
optional charcoal after-filter during

removal and installation after
cleaning.

9. After the unit has been secured, seal
seams air tight with duct tape or

caulking.

Figure 7

ATTENTION: On Electronic Air Cleaners that have the air flow sensor
installed at the factory, be especially careful not to cover the air flow
sensor orifice when sealing the air cleaner and ductwork. This hole is

located on the right hand side of the enclosure that holds the power
pack assembly (when facing the unit). The hole is 3/16" in diameter and

is located on the front of the power tray assembly. In applications with
minimum air flow, it is helpful to seal any openings on the power tray

assembly or cabinet. This will increase the velocity of air flowing over the
air flow sensor, enabling the air flow sensor to turn the Electronic Air
Cleaner on and off. The only opening required for actuation of the
air flow sensor is the 3/16" diameter hole previously described.

10. Refer to the section entitled DIRECTION OF AIR FLOW.

11. Install prefilters and ionizer-collector cells.

12. Reinstall power trayassemblyintothe cabinet.

The Electronic Air Cleaner (without the AFS installed at the factory) is designed to take advantage of the integrated
accessory control panel available on most furnaces. The 12OV Electronic Air Cleaner tap on the furnace will provide

power to the air cleaner only when the circulating air blower isin operation.

Read the instructions in the furnace installation manual carefully before attempting instal_efion or operation. Failure to
follow these instructions may result in improper installation and therefore void warranty.

An optionef(on 120v model) electronic air l_ow sensor kit isavailable ifthe air cleaner is not equipped with an AFS. This
air _ow sensor will sense the air movement w_thin the duct and turn the Electronic/_r Cleaner on and off accordingly.

FURNACE APPLICATION
It is recommended to use EAC t and EAC 2 terminals

when provided by the furnace circuit hoard. These
outputs will provide 120 vac whenever the blower motor

isenergized.
Furnace circuit boards without EAC 1 and EAC 2

terminals MUST use alternate methods to supply to
supply power to the air cleaner. Options include Sail

Switch, Isolation relay or Optional AFS (Air F!ow Sensor)
Air cleaner should only operate when blower motor is

running.

SYSTEM CHECKOUT

_- _,"I",.WARNING: The following procedures should be conducted by a

_ified HVAC contractor or repair person ONLY These procedures

will expose hazardous electrically energized charged components.

Disconnect power between checks and proceed carefullY.

1. The HVAC system blower should be turned OFE

2. Switch the ON/OFF rocker switch to the ON position. The bright red
segment of the rocker switch should be visible.

3. Inspect both the Green INPUT POWER light and the Red CELL
ENERGIZED light:

• If the unit has an AFS installed, the lights should go out in
approximately 20 to 60 seconds. This is the normal time for the

electronic air flow sensor to complete its stabilization period. Both
lights will come back on when the HVAC system blower begins to

operate. See the section entitled HOW THE AIR FLOW SENSOR
WORKS for more information

• Ifthe unit is wired directlyto the HVAC system blower, the lights will not
come on until the blower begins to operate. In this case, the electronic
air cleaner will stay on as long as the ON/OFF switch is in the ON

position and the blower is operating.

• Iftheunitiswireddirectlytoadedicated 120Vpowersource, thelights
will come on immediately and stay on for as long as the ON/OFF
switch is in the ON position, regardless of the HVAC system blower

operation. This type of installation is NOT recommended due to the
excessive production of ozone. See the section entitled FACTS YOU

SHOULD KNOW ABOUT YOUR ELECTRONIC AIR CLEANER -
OZONE for more information.

4. Wait approximately one (1) minute and turn the HVAC system blower
ON. Most thermostats have a setting that will allow you to run the fan

manually. If net, then set the thermostat so that either hot or cold air
begins to flow through the ductwork.

5. The Green INPUT POWER light and Red CELL ENERGIZED light should
come on, if the unit is wired directly to a dedicated 120V power source,
the lights will already be on and will not be affected by the HVAC system

blower operation (see Step 3).

6. Check to make sure that the Red CELL ENERGIZED light goes out when
the following conditions occur:

• Cell access panel is removed

• Rocker switch is switched to the OFF position

• HVAC system blower is not running.
23

TROUBLESHOOTING

CAUTION:

• These procedures should only be attempted by a qualified HVAC

technician or electrician.

• Risk of personal injury could occur by attempting to troubleshoot or
repair this unit by untrained persons.

• Exercise the usual precautions when working with high voltage.

• When the circuit has been de-energized, always discharge any

residual current in the secondary with an insulated handle

_rewddver.

; =

• Always ground power supply and ionizing-collecting Ceil when
bench testing.

Recommended Service Tools

• Screwdriver, 8" common with insulated handle (plastic)

• Screwdrivers Phillips #1 and #2 with plastic insulated handles

• Needle nose pliers

• Multimeter

• High voltage probe

Indication of Electrical Trouble

The air cleaner is equipped with a Red CELL ENERGIZED light for indicating

proper unit operation. When the unit is in normal operation (with the HVAC
system fan running, access door in place and rocker switch in the ON
position) and the Red CELL ENERGIZED light is not lit, the problem is a

shorted secondary. Although failure of the indicating light itself should not
be overlooked, this condition isunusual and rather remote.

24

PRIMARY CIRCUIT WITH FURNACE BLOWER OPERATING

If 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, (Figure 9) to check operation of the switches.

Following these steps to test for proper operation of the circuit board and
power supply assembly:

1. Ensure 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 24V

transformer. It can be checked visually by inspecting the fuse. If the fine

wire inside the fuse is broken, this indicates a problem in the 24V 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. Ifthe fuse is NOT blown, check the ON/OFF switches and safety interlock

switch 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 directly 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 1.0 oh m.

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. If the reading on the meter is greater than 1.0

ohm, the safety interlock switch is defective and must be replaced. If the
reading on the meter is less than 1.0 ohm, the ON/OFF switch is defective

and must be replaced.

25

27

SECONDARY CIRCUIT

IONIZING-COLLECTING CELL

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 material, 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 susceptible to physical damage, The cell also contains the
ionizing wires which, due to their function, have been designed with minimal
structural support and are susceptible 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, turn 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 inthe unit, one at

atime, to determine which cell is shorted.

Most troubles in the cell can be visually detected and corrected (page 12 -Table 1).

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).

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:

1. Make sure the furnace blower is operating, the control switch is on and
input voltage is 120 volts, 60 Hz.

2. Remove front door assembly panel.

3. Remove power pack access cover.

4. Check the high voltage contact board assembly(s) for damage or carbon
tracking.

5. Make connections from the high voltage probe to the multimeter in
accordance with the operatoCs manual. The 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 wire support bar

with end of the high voltage probe (Figure 10). The meter reading should

be 6.2 kVDC ± .2 kVDC,

7. If no voltage is measured, remove the first cell and check the second cell.

The meter should read 6.2 kVDC ± .2 kVDC.

8. If proper voltage is measured, the first cell is shorted. Refer to Table 1, on
page 12.

27

.

If no voltage is present, remove the second cell. Install cell number one
and measure voltage as described above. If voltage is present, the

second cell, which is now out of the cabinet, is shorted. Refer to Table 1
on page 12.

10.

If no voltage is present, remove both cells and measure the power
supply output. While depressing the safety switch, touch the end of the

high voltage probe to either the front or rear contact board assembly

(Figure 10). The meter should read 6.2 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.

13. If there is no output voltage from 24 volt transformer, replace the 24 volt

transformer and power supply board.
