AIR FLOW SENSOR (AFS) – senses the movement of air
with the duct. It reduces power usage and prevents build
up of ozone within the duct. The AFS utilizes a thermistor
that is heated to approximately 130°F and stabilizes at this
temperature. When the system blower is energized and air
flows through the duct system, a vacuum affect pulls air
over the thermistor, thus cooling it. This cooling effect
signals the electronic air cleaner to turn on and provide air
cleaning.

General Information

DUSTING AND “WHITE DUST”

Your new Electronic Air Cleaner (EAC6) 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 that
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 by­product. 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 fact, the ozone
level in major cities can sometimes reach as high as 100
ppb on a summer day. The addition of optional charcoal
after-filters can help reduce this.

Normally, a new unit will produce more ozone than one that
has been in operation for several weeks. This is due to
sharp corners or manufacturing burrs on the ionizing­collecting 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 a part of the

breaking in period of ownership and the issue is self­correcting. 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

This electronic air cleaner (technically known as a two­stage electrostatic precipitator) is designed to remove
airborne particulates – dust, dirt, smoke, pollen, virus,
spores, bacteria, mold – from indoor air.

It is used in forced air heating, cooling and ventilating
systems. As dirty air enters the air cleaner, the air passes
through a metal mesh pre-filter. The pre-filter prevents lint,
pet hair and other large particulates from entering the air
cleaner by impingement. It is important that these filters be
in place to prevent excessive dirt loading of the air cleaner
collector cells. These filters extend the time between
maintenance of the air cleaner collector cells. This allows
the collector 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 the submicron sized, are electrically 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 pass
into an intense electrical field established between alter­nately charged and grounded parallel plates. Here the
positively charged particulate is attracted to the ground
plates and is precipitated out of the air stream.

Because of a built-in electronic air flow sensor; the air
cleaner operates automatically with the system blower.
The air cleaner should be installed in the system so that all
the system air is circulated through the air cleaner. The
EAC6 will only remove the airborne contaminants deliv­ered to it. Maximum performance is obtained when the
system blower is set for continuous operation. For high
altitude applications, see Troubleshooting (Qualified

Servicer Only) section.

PRE-INSTALLATION CONSIDERATIONS AND REQUIREMENTS

CAUTION

Read rules and instructions carefully for safe operation. Failure to follow them could damage your unit or cause a
hazardous condition. Check your unit ratings given on the cleaner to ensure it is suitable for your application.

PLACEMENT

The best location for the air cleaner is in the return air duct
next to the blower compartment. In this location, the blower
motor and cooling coils will be kept the cleanest.

DO NOT INSTALL THE AIR CLEANER IN THE DIS­CHARGE AIR DUCT. Before installing the air cleaner,
consider the application (see Figures 3 to 8). If a transition
is required, refer to section entitled “Transitions”. The unit
must be readily accessible for periodic inspection and
cleaning of the pre-filters and electronic cells to maintain
maximum efficiency and trouble-free operation.

AIR CONDITIONING

The air cleaner should be installed upstream of the cooling
coil. This will keep the coil clean and reduce air condition­ing coil maintenance. Improved cooling efficiency is the
result that 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.

OUTDOOR AIR

When outdoor air is added to the return air duct, sufficient
heat should be added to maintain the return air tempera­ture of 40°F (4°C) minimum. Lower temperatures can
cause ionizer wire failure.

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 (see
Figure 2).

AIRFLOW

HUMIDIFIERS

An evaporative humidifier can 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 it as far upstream as possible. (Recommend
at least 10 feet.)

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 deposit buildup.
