voltage as described in step #7. If voltage is present, the second cell, which is now out
of the cabinet, is shorted. Refer to the section entitled COMMON TROUBLE-
SHOOTING TECHNIQUES (page 9).
11. If no voltage is present, remove both Ionizing-Collecting Cells and measure the power
supply output. While depressing the safety interlock switch lever, touch the end of the
high voltage probe to either the front or rear contact board assembly. The meter should
read 6.2 KVDC or higher.
12. If no voltage is present, check the transformer. Set the Multimeter for reading AC
voltage at 200 volts full scale and attach meter test leads to the junction of the
transformer secondary leads and the circuit board. The meter should read 24 volts +/–
4 volts.
13. If there is no voltage from the transformer, replace the transformer and power supply
board.

‘ Introduction ‘
This Electronic Air Cleaner is 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
Prefilters. The Prefilters 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 allows the Ionizing-Collecting Cells to
provide clean air for a longer period between washings.
The pre-filtered air then passes through two-stage Forever Filter®Ionizing-Collecting Cells.
In the first stage, all airborne particulate, even submicron size, are electronically charged
(positive) as they pass through the ionizer section. The ionization 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.

‘ Unit Components ‘
Cabinet
Mounts to existing ductwork; houses the Ionizing-Collecting Cells and Prefilters.
Ionizing-Collecting Cells (Forever Filter®)
Collects 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.
Prefilters
Traps large particulates before they enter the Ionizing-Collecting Cell.
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 Power Tray allows the unit to be connected to a standard NEMA electrical receptacle
(NEMA 5-15R for 120 volt units and NEMA 6-20R for 240/250 volt units). European
models are supplied without a plug on the line cord to allow installation of desired plug or
permanent wiring to an electrical junction box (by others). 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
reduce power usage when the HVAC system
blower is not in operation. The AFS is
designed to provide an efficient and reliable
method of controlling the operation of the air
cleaner when the installer is unable to wire the
unit directly into the HVAC System Blower
Control Circuit. The AFS utilizes a thermistor,
which 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.

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 (page. 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 between stainless steel spring
contact and grounded metal). Clean or replace Contact Board assemblies and cell
contacts 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 +/- 0.2 KVDC. 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.
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 +/- 0.2 KVDC.
9. If proper voltage is measured, the first cell is shorted. Refer to section entitled
COMMON TROUBLESHOOTING TECHNIQUES (page 9).

Secondary Circuit - Ionizing-Collecting Cells
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 cells
should be periodically removed from the unit to wash away collected dirt, it is susceptible to
physical damage. The cells also contain 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 (page 9).
Notice: 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).

‘ Operation ‘
Regular 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. Operating the HVAC system 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 high
voltage is vaporizing these areas and tends to round them off. This is part of the breaking-
in period 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.

‘ Operation ‘
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 Power Tray 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 (see illustration below).
5. With a pair of needle nose pliers, carefully relocate the jumper from setting HIGH (H) to
MED (M). 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 relocate the
jumper from setting MED (M) to LOW (L).
This unit is produced at the factory with the jumper 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.

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 (page
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 24V circuit. Do NOT replace this fuse. The entire Power Supply
Assembly 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 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
WARNING:
• 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(s) 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) Circuit
WARNING:
The following procedure must be performed by an authorized HVAC contractor.
Failure to do so may result in 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 Thermistor, a small circuit with a small gray disc connected to the
power supply by two silver wires. Refer to the section entitled AIR FLOW SENSOR
(AFS) (page 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.

‘ Maintenance ‘
Washing Ionizing-Collecting Cells and Prefilters
Regular washing of the Forever Filter®Ionizing-Collecting Cells is necessary to ensure
proper performance. A thorough washing once every six months will be adequate for most
installations. More frequent washing (once every one to three months) may be necessary
with some installations (new home for example) where there is new carpeting, plaster dust,
or excessive cigarette smoke.
CAUTION:
Handle Ionizing-Collecting Cells with care as cell plates can be sharp and cause injury if
not handled properly.
Remove Ionizing-Collecting Cells and Prefilters 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 Cells and Prefilters and set aside in a safe
place.
3. Do not drop the Ionizing-Collecting Cell(s). This can cause damage to the cell plates or
ionizing wires which results in excessive arcing and poor performance.
Wash Ionizing-Collecting Cells and Prefilters:
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 the cell up and down in the solution until it
appears clean and remove the cell from the solution.
3. Repeat steps 1 and 2 for second cell.
4. Agitate the Prefilters up and down in the solution until they appear clean.
5. With a water hose, rinse the Ionizing-Collecting Cells and Prefilters. 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 length of the ionizing wires.
6. Stand Ionizing-Collecting Cells and Prefilters 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.
Replace Cells in the Air Cleaner:
1. Replace Prefilters 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).
3. Turn air cleaner ON/OFF switch to ON position.

- 6 -
‘ Maintenance ‘
Replacing Ionizing Wires in Ionizing-Collecting Cells
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
service.
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.
Procedure for 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 (AFS):
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
prevent 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 in 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.

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 (AFS) 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 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.

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 the Input Power Source
A power cord is provided for connection to a standard NEMA electrical receptacle (NEMA
5-15R for 120 volt units and NEMA 6-20R for 240/250 volt units). European models are
supplied without a plug on the line cord to allow installation of desired plug or permanent
wiring to an electrical junction box (by others). If the unit is to be permanently connected to
the furnace control, a wiring compartment (with a knock-out hole) is provided on all models
at the rear of the Power Tray Assembly. The wiring compartment is accessible by
removing the Power Tray Cover.

‘ Questions and Answers ‘
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 is not 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 is not 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.
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.

‘ Questions and Answers (continued) ‘
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 illuminate while the HVAC system blower is in operation after
an electrical 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 do not
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 50W
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.

‘ Installation ‘
‘ For Qualified HVAC Installer Only ‘
Application
The air cleaner is used in forced air heating, cooling, and ventilating systems. It should be
installed in the system such 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 with the HVAC system blower set for continuous operation.
Installation Requirements
• The best location for the air cleaner is in the return air duct next to the HVAC blower
compartment. In this 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 Typical Mounting Positions section for the most common configurations.
• Refer to the Transitions section if a transition is required between the duct work and the
air cleaner.
• The unit must be readily accessible for periodic inspection and cleaning of the Prefilters
and Ionizing-Collecting Cells to maintain maximum efficiency and trouble free operation.
Air Conditioning
The air cleaner should be installed upstream of the cooling coil to keep the coil clean and
reduce air conditioning coil maintenance. A clean coil will reduce utility costs by
maintaining the coil’s efficiency. 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 in the air
cleaner. Arcing will reduce air cleaner’s efficiency and reduce the life of the high voltage
power supply.
Evaporative Humidifiers
An evaporative type humidifier can be mounted either upstream or downstream of the air
cleaner, depending upon the desired humidification capacity.
- 13 -
‘ Installation ‘
‘ For Qualified HVAC Installer Only ‘
Atomizing Humidifiers
If an atomizing humidifier is mounted upstream of the air cleaner:
1. Mount the humidifier as far upstream in the ductwork as possible. A distance of at least
10 feet is recommended 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 hard water buildup.
If an atomizing humidifier is mounted downstream of the air cleaner:
No additional considerations required.
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
section.
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.
Turning 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. Failure to follow this
recommendation can reduce the
efficiency of the Electronic Air Cleaner.
