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 Metal Mesh Pre-filters. The Pre-

filters prevent 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

Ionizing-Collecting Cells. These filters extend the time interval between scheduled maintenance

of the air cleaner, which allow the Ionizing-Collecting Cells to provide clean air for a longer

period between washings.

The pre-filtered 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 section. The ionizer field is a result of 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 charged (positive)

particulate is attracted to the ground (negative) plates and removed from the air stream.

Introduction

SECONDARY CIRCUIT POWER SUPPLY

If the Red CELL ENERGIZED light remains out with the Ionizing-Collecting Cells

removed from the cabinet, the power supply is defective. Specific problems in

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 (pg. 20). To check for proper

operation, it is imperative that the procedure be followed as outlined below:

1. Make sure the HVAC system is operating, the air cleaner ON/OFF switch is

ON, and air cleaner input voltage is correct (120V, 50-60Hz for 120V units

and 240V, 50-60Hz for 240V units).

2. Remove Front Panel Assembly from air cleaner.

3. Remove Power Tray Assembly Cover.

4. Check the high voltage contact board assembly for damage or carbon

tracking.

NOTE: The cell contacts must be visually checked for corrosion, excessive dirt

build up, and electrical arc tracking (Carbon path from stainless steel spring to

grounded metal). Clean or replace as required.

5. Replace both Ionizing-Collecting Cells in the air cleaner cabinet.

6. Make test connections from the High Voltage Probe to the Multimeter in

accordance with the probe’s instruction manual. The Multimeter should be

set for reading DC voltage at 20 volt full scale.

7. Attach the High Voltage Probe ground lead to the air cleaner cabinet.

While depressing the safety interlock switch lever, touch the ionizer wire

support with end of the High Voltage Probe. The meter reading should be

6.2 kVDC + .2 kVDC.

8. If no voltage is measured, remove the first Ionizing-Collecting cell and

check the second cell by repeating step #7. The meter should read 6.2

kVDC + .2 kVDC.

9. If proper voltage is measured, the first cell is shorted. Refer to COMMON

TROUBLESHOOTING TECHNIQUES (pg. 9).

Troubleshooting

Cabinet

Mounts to existing ductwork; houses the Ionizing-Collecting Cells and Pre-filters.

Ionizing-Collecting Cells

Collect the dust, dirt and other particulates in the air. They contain the ionizing and collecting

sections. The cells must be installed with the ionizing wires on the air intake side. A spring

contact is located on the top of each cell and must be in the position to make contact with the

contact board assemblies on the bottom of the Power Tray Assembly.

Pre-filters

Trap large particulates before they enter the Ionizing-Collecting Cells Power Tray Assembly.

Power Tray Assembly

Contains the indicating lights, solid state power supply, contact boards and electrical controls

including the ON/OFF switch and safety interlock switch. A power cord at the rear of the 120 volt

Power Tray allows the unit to be connected to a standard 120 volt outlet. A wiring compartment

is provided on all models at the rear of the Power Tray allowing the option to permanently wire

the unit directly to the HVAC System Control.

Air Flow Sensor (AFS)

Controls the operation of the unit by sensing the movement

of air within the duct. This helps to reduce power usage.

The AFS is 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 HVAC

System Blower Control Circuit. The AFS utilizes a thermistor,

when electrically powered, heats up to approximately 130° F.

The AFS stabilizes at this temperature and while the HVAC

System Blower is in operation, air flows through the ductwork, creating a vacuum effect that

pulls cooler air over the hot surface of the thermistor. This air movement cools down the

thermistor which allows the AFS to register that the HVAC System blower is moving air and the

Electronic Air Cleaner must be powered to provide air cleaning.

Air Cleaner Model Identification

The model number and part number for your Electronic Air Cleaner can be found on the data

label located on the inside of the Front Panel Assembly.

Unit Components

For Qualified HVAC

Installer Only

SECONDARY CIRCUIT

IONIZING-COLLECTING CELL

The cells are electrically energized through a contact terminal located at the

top center of each 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 have been designed due to their

function with minimal structure support and are susceptible to breakage. Short

circuit issues related to dirty or damaged Ionizing-Collecting Cells are readily

identified by the lack of illumination of the Red CELL ENERGIZED light and

quickly identified and isolated by a simple procedure.

To determine if a short circuit condition exists in one or both Ionizing-

Collecting Cell(s), turn the Electronic Air Cleaner OFF. Remove both Ionizer-

Collecting Cells from the cabinet. Re-position the Front Panel Assembly to the

cabinet, turn ON/OFF switch ON and ensure HVAC system blower is operating.

The Green INPUT POWER light should illuminate. If the Red CELL ENERGIZED

light illuminates, an electrical short circuit exists in one or both of the Ionizing-

Collecting Cells. Replace the cells, one at a time, to determine which cell has the

short circuit. The Red CELL ENERGIZED light will not illuminate if a short circuit

condition is detected.

Most short circuit troubles in the cell can be visually detected and corrected.

Refer to COMMON TROUBLESHOOTING TECHNIQUES (pg. 9).

NOTE: The Ionizing-Collecting Cells are not designed for field repair. Ionizing

wires and insulators can be field replaced; however, it is not recommended

that you attempt to replace other cell components (i.e. collecting plates, end

plates, ionizer wire supports).

Troubleshooting

Dusting and “White Dust”

Your new Electronic Air Cleaner will efficiently clean and filter your household air. It will not

eliminate the need for regular dusting of your furniture and belongings. Duct-mounted air

cleaners can only clean 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. 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

telephones 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 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 the smell of

ozone generated by the air cleaner.

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 Plates

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.

Circuit Diagram

PRIMARY CIRCUIT WITH HVAC SYSTEM BLOWER OPERATING

• If there is no supply line voltage at the transformer input connections,

correct the fault at the dedicated power source or HVAC system power

source.

• If there is supply line voltage at the transformer input connections and

no output voltage (24 volts nominal), the transformer is defective and

must be replaced.

• If there is transformer output voltage ( 24 volts nominal) and no output

voltage from the ON/OFF switch, the outage can be located by checking

operation of the safety interlock switch and the interconnecting wiring

with a Multimeter. Refer to Circuit Diagram, (pg. 22) to check operation

of the switches.

PRIMARY CIRCUIT WITH HVAC SYSTEM BLOWER NOT OPERATING

Follow these steps to test for proper operation of the Power Supply Board,

ON/ OFF Switch, and Safety Interlock Switch.

1. Ensure that the circuit controlling the HVAC system blower is in the OFF

position, and input power to the air cleaner is disconnected.

2. The power supply board has a built-in internal fuse to protect the 24V

transformer. The fuse can be checked visually by inspection. If the fine

wire inside of the fuse is broken, a fault exists in the 24 circuit. Do NOT

replace this fuse. The entire Power Supply Assembly must be replaced.

The purpose of the fuse in 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 switch and safety interlock

switch for proper engagement and operation. This can be completed

using a Multimeter with an OHM scale capable of reading 1.0 ohm.

4. Remove the fuse. Connect one Multimeter test lead to the test pin hole

(J9) located directly beside the wire that connects the ON/OFF switch to

the power supply board. Connect the other Multimeter test lead to the

fuse connection nearest the front panel

5. Turn the ON/OFF switch to the ON position and depress the safety

interlock switch. The Multimeter should have the capability of reading

levels as low as 1.0 ohm. Multimeter reading of 1.0 ohm or less indicates

correct operation of the ON/OFF switch and the safety interlock switch.

6. If the Multimeter ohm reading is greater than 1.0 ohm, begin the process

of elimination by moving the Multimeter test lead from the test pin hole

(J9) to the safety interlock switch terminal with the blue wire lead.

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.

Troubleshooting

High Altitude Operation

Because the air is less dense at higher altitudes,

there is a possibility of nuisance arcing in the

Electronic Air Cleaner. The homeowner can quickly

and easily correct this condition.

1. Make sure the HVAC System Blower is not

operating, the ON/OFF switch is in OFF position

and the circuit breaker is turned OFF or input

power cord is disconnected.

2. Remove the Front Panel Assembly.

3. Remove the cover from the Power Tray

Assembly by removing the two screws on top of

unit. (The entire Power Tray Assembly may be

removed from the cabinet by removing two

screws from inside the cabinet.)

4. Locate the jumper terminal.

5. With a pair of needle nose pliers, carefully

relocate the jumper settings from HIGH to MED.

Ensure that the jumper is firmly seated in the

terminal.

6. Replace the Power Tray Cover and secure it with

two screws.

7. Replace the Front Panel Assembly, turn circuit

breaker ON, reconnect input power cord and

turn ON/OFF switch 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 (M) to LOW (L).

This unit is produced at the factory with the jumpers

set in the HIGH (H) position. However, the output

voltage may be lowered in any situation where the

unit is arcing excessively or there is excessive ozone.

TROUBLESHOOTING

CAUTION:

• These procedures must be performed by a qualified HVAC technician or

electrician.

• Risk of personal injury or death 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 circuit with an insulated handle screwdriver.

• Always ground power supply and Ionizing-Collecting cell when bench

testing.

RECOMMENDED SERVICE TOOLS

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

• Screwdrivers, Phillips #1 and # 2 with insulated handle (plastic)

• Needle Nose Pliers with insulated handles (plastic)

• 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 blower running, Front Panel Assembly in place and ON/OFF switch in

the ON position) and the Red CELL ENERGIZED light is not illuminated, the

problem is a shorted secondary circuit or Air Flow Sensor fault. Although

failure of the indicating light itself should not be overlooked, this condition is

unusual.

AIR FLOW SENSOR (AFS) TROUBLESHOOTING

The following procedure must be performed by an authorized HVAC

contractor. Failure to do so may expose an individual to serious personal injury

or death.

1. Make sure the HVAC system blower is not operating, the ON/OFF switch is

in OFF position and the circuit breaker is turned OFF or input power cord

is disconnected.

2. Remove the Front Panel Assembly.

3. Remove the cover from the Power Tray Assembly by removing the two

screws on top of unit.

4. Locate the AFS, a small circuit board with a small gray disc connected to

the board by two silver wires (see Air Flow Sensor (AFS) pg. 2). Carefully

bend the thermistor (small gray disc) wire leads so the thermistor is

located in the center of the 3/16” diameter hole in the Power Tray

Assembly and approximately 1/8” from the inside edge of the Power Tray

Assembly front.

Troubleshooting

WASHING IONIZING– COLLECTING CELLS AND PRE-FILTERS

Regular washing of the Ionizing-Collecting Cells 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 with some installations (new home for

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

To Remove the Ionizing-Collecting Cells and Pre-filters from the Air Cleaner:

1. Turn air cleaner ON/OFF switch to OFF position. Wait 15 seconds. Remove Front Panel Assembly.

2. Carefully remove the Ionizing-Collecting Cell(s) and Pre-filter(s) and set aside in a safe place.

3. Do not drop the Ionizing-Collecting Cell. This can cause damage to the cell plates or ionizing

wires which results in excessive arcing and poor performance.

To Wash Ionizing-Collecting Cells and Pre-filters:

We suggest you follow the instructions below to properly and thoroughly clean your

Ionizing-Collecting Cells.

1. Place enough hot water in a utility tub to cover the first cell. Dissolve 2-4 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 (if applicable).

4. Agitate the Pre-filters up and down in the solution until they appear clean.

5. With a hose, rinse the Ionizing-Collecting Cells and Pre-filters. The hose should be held

about 10” from the cell plates and at a slight angle for maximum cleaning results. Be careful

not to spray the ionizing wires directly with the hose as the water pressure can cause the

wire(s) to stretch 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 Ionizing-Collecting Cells and Pre-filters in upright position and allow to dry two hours.

You may experience a slight discoloration of the aluminum collector cell plates after

washing. This is a normal chemical reaction between the aluminum and detergent and will

not harm your unit or affect its performance.

To Replace Cells in the Air Cleaner:

1. Replace Pre-filter and Ionizing-Collecting Cells in cabinet. Check that airflow arrow on Cells

point in same direction as air flows through the duct. (If you have to force the cell past the

positioning screw in the cabinet bottom, the cell is probably in the incorrect position.)

2. Replace Front Panel Assembly (engage tabs on lower edge of door into slots in cabinet).

Carefully close the Panel.

3. Turn air cleaner ON/OFF switch to ON position.

Maintenance

NOTICE: Handle Ionizing-Collecting Cells with care as plates can be sharp and cause injury

if not handled properly.

SYSTEM CHECKOUT

WARNING: The following procedures must be conducted by a qualified

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 OFF.

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:

System With Air Cleaner INPUT POWER From Dedicated Power Source

• The Green INPUT POWER light should illuminate and remain

illuminated.

• The Red CELL ENERGIZED light should illuminate and 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. The

Red light will come back on when the HVAC system blower begins to

operate. See the section entitled AIR FLOW SENSOR pg. 2, for more

information.

System With Air Cleaner INPUT POWER From HVAC System

• Neither Green INPUT POWER light nor Red CELL ENERGIZED light

should illuminate.

4. Wait approximately one minute and turn the HVAC system blower ON.

Most thermostats have a setting that will allow you to operate the blower

manually. If not, set the thermostat so that either hot or cold air begins to

flow through the duct work.

System With Air Cleaner INPUT POWER From Dedicated Power Source

• The Green INPUT POWER light should remain illuminated.

•The Red CELL ENERGIZED light should illuminate within

approximately 20 to 60 seconds, and remain illuminated while the

HVAC system blower is in operation.

System With Air Cleaner INPUT POWER From HVAC System

• The Green INPUT POWER light should illuminate and remain

illuminated.

• The Red CELL ENERGIZED light should illuminate within

approximately 20 to 60 seconds and remain illuminated while the

HVAC system blower is in operation.

5. Check to make sure that the Red CELL ENERGIZED light goes out with the

following conditions:

• Front Panel Assembly is removed

• ON/OFF switch is switched to the OFF position

• HVAC system blower is not running

Installation

REPLACING THE IONIZING WIRES

Instances of the Ionizing Wires breaking are minimal due to 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 a

broken Ionizing Wire as long as the broken wire has not caused a short in the secondary circuit

of the unit. Remove all loose and broken wires as soon as they are identified.

We recommend contacting a qualified HVAC contractor for replacement parts and/or servicing.

Ionizing 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 Ionizing-Collecting Cell. The removal of broken wires will prevent accidental

shorting of the cell and reduce the need for further maintenance.

Use the following procedure when replacing an Ionizing Wire:

1. Turn Air Cleaner ON/OFF switch to OFF position. Wait 15 seconds. Remove the Front Panel

Assembly and remove the Ionizing-Collecting Cells from the unit.

2. Carefully remove all remains of the broken wire from the cell.

3. Grip the new wire at each end 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 wire support located on the

Ionizing-Collecting Cell as viewed 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 in the wire support on the opposite end of the Ionizing-

Collecting Cell.

6. The wire should have sufficient tension to be self supporting and remain suspended

between the slots in the wire supports.

CLEANING THE AIR FLOW SENSOR

If the air cleaner is installed in a location that is dusty and dirty, the sensor (thermistor) 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, turn the unit OFF, dip a cotton swab in rubbing

alcohol and carefully insert into the 3/16” diameter hole located on the front right hand side of

the Power Tray Assembly (when facing the unit). Carefully twirl the cotton swab between your

fingers, making sure the tip is lightly in contact with the gray disc (thermistor), cleaning the

insulating coating from the thermistor.

ELECTRICAL INSTALLATION

CAUTION:

If the Electronic Air Cleaner is wired directly to the

integrated accessory control on the furnace, it is

imperative that the ampere rating of the control be

sufficient to handle the current required by the air

cleaner. All wiring shall be performed in accordance

with the National Electric Code.

CAUTION:

Do not wire the Electronic Air Cleaner directly to a

multiple speed blower motor. Wiring to a multiple

speed blower motor will damage the Air Cleaner

power supply and void the warranty.

Read the instructions in the furnace installation

manual carefully before attempting installation or

operation of the Electronic Air Cleaner. Failure to

follow these instructions may result in an improper

installation and therefore void the HVAC system and/or

Air Cleaner warranty.

PROCEDURE FOR WIRING THE ELECTRONIC AIR

CLEANER TO INPUT POWER SOURCE

A power cord is provided on the 120 volt model for

connection to a standard 120V receptacle. If the unit is

to be permanently connected to the furnace control

panel, a wiring compartment (with a knockout hole) is

located at the rear of the Power Tray Assembly. It is

accessible by removing the Power Tray Cover.

COMMON QUESTIONS AND ANSWERS

Q. Why isn’t my Electronic Air Cleaner cleaning my air?

A. The air cleaner is most likely working just like it was designed. However, many factors can

affect the performance of the unit. Are air return registers located in the ceiling? If so, it will

be difficult for the air flow to carry heavier particulates to the air cleaner. If the dirt does

not get to the air cleaner, it cannot be removed from the air. Are both the Red and Green

indicating lights illuminated? If not, the unit may be in need of servicing.

Q. It still isn’t cleaning my air the way I want it to. What can I do?

A. It is recommended that you operate the HVAC system continuously so that the air movement

will carry the dirt to the air cleaner where it can be collected. 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 air stream 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 isn’t working!

A. The air cleaner is operating properly as long as both the Red and Green indicating lights are

illuminated. Try turning the HVAC blower ON and then turning the Electronic Air Cleaner

ON. This should solve the problem.

Q. What is the 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-Collecting 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-Collecting Cell, and are “vaporized”.

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-Collecting Cells. However, if the sound is constant or is repetitive in nature, then a

large particle may have become lodged in the Ionizing-Collecting cell and may require

removal by cleaning. If cleaning the Ionizing-Collecting Cell does not stop the noise and/or

there are no large particles trapped in the Ionizing-Collecting Cell, then the cause could be

a broken/loose ionizing wire, bent collector plate or other mechanical fault.

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.

1. Locate the cabinet in the cold air return duct

such that all of the return air flows through

the unit. If the furnace and air cleaner

openings are different, use a transition.

2. Mounting holes are provided in the Air

Cleaner cabinet for ductwork attachment. The

.140” diameter holes are sized for #8 sheet

metal screws, or 1/8” rivets. If the adjoining

ductwork is flanged, install the screws with the

screw heads inside the cabinet to prevent

damage to the Air Cleaner Pre-filters and

optional Charcoal After-Filters during removal

and installation during scheduled

maintenance.

3. After the cabinet has been mounted, seal

seams air tight with duct tape or caulking.

ATTENTION: Be especially careful not to cover the

Air Flow Sensor orifice when sealing the air cleaner

and ductwork. This 3/16” diameter hole is located

in the front of the Power Tray Assembly.

4. Refer to the section entitled DIRECTION OF AIR

FLOW - Confirm correct airflow direction.

5. Install Power Tray Assembly onto the cabinet.

6. Install Pre-filters and Ionizing-Collecting Cells

into cabinet.

7. Install unit’s Front Panel Assembly onto

cabinet.

Installation

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

noises. Second, the HVAC system blower is not operating 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 Electronic Air Cleaner will

not turn on properly after power is restored. If the Green INPUT POWER indicating light is

illuminated, and the Red CELL ENERGIZED indicating light is illuminated while the HVAC

system blower is operating, the unit is operating properly. To reset the Electronic Air

Cleaner, turn the HVAC system blower OFF, turn air cleaner OFF, wait one minute, turn air

cleaner ON, and then turn HVAC system blower ON. If the Red and Green lights do NOT

come on while the HVAC system blower is in operation, after a storm, the power supply in

the Electronic Air Cleaner may be short circuited. Contact your local HVAC contractor for

further assistance.

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 operating all the time to

achieve the maximum air cleaning efficiency of the Electronic Air Cleaner. 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 and size of your system, energy costs in

your regional location and other variables.

The best solution is to operate the HVAC system blower in a continuous mode for a month

or two, estimate annual energy costs, and base your final decision with what you feel most

comfortable.
