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 isprovided 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 allows 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, alf
airborne particulate, even submicron size, are electronically charged (positive) as they pass
through the ionizer sectiom The ionizer field is a result of a corona discharge emanating from

the fine, tightly strung wires suspended between two adjacent flat piates, 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.

I

Cabinet

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

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

THERMISTOff

\,

AIR FLOWSENSOR

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° RThe 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°

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. 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 ]onizing_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 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<harged and ground components has been decreased) may also produce an

abnormal amount of ozone.

HighAltitudeOperation
Becausethe 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 conditiom

1_ Make sure the HVAC System Blower is not

operating, the ONIOFF switch is in OFF position
and the circuit breaker is turned OFF or input

power cord isdisconnected°
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_

5.

Locate the jumper terminal°

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°

7o Replace the Front Panel Assembly, turn circuit

breaker ON, reconnect input power cord and

turn ONtOFF 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,

WASHINGIONIZING-COLLECTING CELLSAND PRE-FILTERS

Regu{ar 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 fonizing+Coliecting CeiL(s)and Pre-filter(s) and set aside in a safe place_
3+Do not drop the Ionizing-Collecting Ce!loThis 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_

4+
5,

+

Repeat with second cell (if applicable),
Agitate the Pre-filters up and down in the solution until they appear clean.
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,

Stand Ionizing-Collecting Cells and Pre-filters in upright position and allow to dry two hours_
You may experience a slight discoloration of the a[uminum 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 ceil 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_

REPLACING THE IONIZING WIRES

Instances of the Ionizing Wires breaking are minimal due to the constant tension design and

fixed location of the lonizing Wire supports. When an Ionizing Wire breaks, the efficiency of the

Electronic Air Cleaner will decrease slightty_ 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:

1o 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 cello
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 asviewed from the front of the cell. This support ispartially covered
by the cel! brace in front of the support°

5, Grip the other end of the tonizing 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 lonizing-
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 AF5 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,

Q.

Q,

Ao

a_

Why isn't my Electronic 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 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.
It still isn't cleaning my air the way 1want it to, What can 1do?
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 isleft 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.

When t 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!

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
What is the zapping noise I am hearing from my unit? Should I be concerned?
The zapping or popping noise that you are hearing isthe sound of larger particles

being "vaporized" by the Ionizing-Collecting Cel!oThis 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",

Should 1hear this zapping noise all the time?
All Electronic Air Cleaners will occasionally zap or pop as larger particles pass

through the lonizing_Colfecting Ceils° However, if the sound is constant or is
repetitive in nature, then a large particle may have become lodged in the lonizing_
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.

What if I no longer hear any popping or zapping noises coming from my unit? Is

it still cleaning the air?

tf 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.
