GENERAL
The electronic air cleaner is designed to remove atmospheric and household dust, pollen, mold spores, bacteria, fungi,
insecticide dust, animal dander, coal dust, mites, cooking
smoke and grease, tobacco smoke, and other particles down to
sub-micron levels.
The electronic air cleaner is installed in the furnace fi lter
rack where a filter would nor mally be pl ace d. It is designed t o
be installed in a 1-in. filter track. Many sizes are available to fit
in different size air ducts.
Airborne pollutants are carried through the return air ducts
of the heating/cooling system to the elec tronic a ir cleaner. The
collecting pads of the electronic air cl eaner utilize electronic
polarization and ionization to create high filtration efficiencies.
The particles are captured by the collecting pads. The 1-in.
design protects HVAC equipment and their energy efficiencies
due to the electronic air cleaner’s low static pressure.
Regular maintenance (replacement or cleaning of collecting
pads) is required by the home owner.
See Fig. 1 for a description of the electronic air cleaner.
Frames with Outer Screens —
up of two sides. An optional key is supplied with the frame and
may be used to lock and unlock the corner fasteners. The key is
located over the top of the outlet and LED lights. The outer
screens may be vacuumed or washed when dirty.
Collecting Pads —
the air. One of the collecting pads will contain carbon fibers
which are used to ionize and polarize the pads. The pads cannot
be washed or vacuumed and must be replaced when dirty.
Charging Bar —
the collecting pad with the carbon fibers and must be in contact
with the carbon fibers on the pad. The charging bar is energized
by the high voltage power supply box.
The collecting pads are used to filter

INSTALLATION
Location —
cleaner should be installed in t he filter rack. Note the dimensions of the filter rack and order the appropriate sized electronic air cleaner to fit the rack.
If a filter rack does not exist, then the el ectronic air cleane r
must be installed in the return air duct, as close to the blower
compartment as possible. This location provides the most even
airflow across the collection pads and allow s the electr onic air
cleaner to keep the system motor and blower clean. When
choosing location, there must be adequate room to remove the
electronic air cleaner. It is best to use the largest possible electronic air cleaner size for installation.
Be sure to allow room for routing the 24-V power wiring to
a 24-VAC power source.
NOTE: Be sure to notify home owner not to install any device
within 3 ft from the side of the electronic air cleaner after
installation is complete. Regular servicing of the electronic ai r
cleaner is required. A 3-ft clearance is required to remove electronic air cleaner and collection pads for maintenance or
replacement.
If a filter rack exists, then the electronic air
HIGHBOY FURNACE — The fil ter rack i s nor mall y loc ated
in the return air duct.
LOW BO Y FU RN AC E — The filter rack is normally located
in the blower compartment section. Remove the blower compartment door to view filter rack.
ELECTRIC FURNACE — The filter rack is normally
located in the bottom furnace section, located horizontally
above the filter box.
LOWBOY FURNACE (O IL) — The filter rack is normally
located in the blower compartment section. Remove the
blower compartment door to view filter rack. Some older furnaces are equipped with two racks, an upper horizontal and a
lower diagonal. The air cleaner would be placed in the lower
diagonal filter rack.
HORIZONTAL FURNACE — The filter rack is normally
located in the return air duct.
FULL SIZE EXISTING ELECTRONIC AIR CLEANER —
If the new electronic air cleaner is replacing an existing full
size air cleaner, be sure to turn off the existing air cleaner
before removal.
INSTALLATION LOCATION WITH HUMIDIFIER — If
a separate humidifier is purchased, it should be installed in the
furnace warm air duct. However, a humidifier may be installed
in the return air duct without causing problems to the electronic
air cleaner. Care must be taken to ensure that the humidifier
does not leak, as this may cause damage to the electronic air
cleaner and mineral deposits on the air cleaner.
Wet collection pads may cause arcing or shorts on the electronic air cleaner. Wet collecti on pads may also decrease electronic air cleaner efficiency.
NOTE: An atomizing-type humidifier should only be installed
downstream of the electronic air cleaner. If the atomizing-type
humidifier is installed upstream, high humidity, salts, and minerals may damage the electronic ai r cleaner and cause servic e
problems. If the atomizing-type humidifier must be installed
upstream, the atomizing-type humidifier must be installed as
far from the electro nic air cl eaner as po ssible.
INSTALLATION LOCATION WITH AIR CONDITIONER — Whenever possible, the electronic air cleaner
should be installed upstream of the cooling coil. This location
will clean the air before it reaches the evaporator coil.

Electronic Air Cleaner Installation —
Perform the
following to install the electronic air cleaner.
1. If a filter rack exists, remove the ex isting f urnace f ilter.
Thoroughly clean the blower compartment and ductwork where the electronic air cleaner is to be installed.
If a filter rack does not exist, fabricate a filter rack
using the location information provided in the Location section on this page.
2. Place electronic air cleaner in filter rack. Ensure that
there is no air leakage.
3. Wire the power cord to a 24-V power source. See
Fig. 2. Use a voltmeter to positively identify that the
power source is a 24-V (maximum 30-V) source. A
field-supplied 110-V to 24-V adapter or transformer
may be used to provide 24-V power. Ensure that the
electronic air cleaner is properly grounded.
NOTE: If one terminal of the power source is
grounded, connect the white striped wire of the power
cord to this terminal.
After installation of the electroni c air cleaner, you may notice some white dust on table tops and shelves. Most heavy
particles (such as lint) settle quickly and do not get filtered
through the electronic air cleaner. To reduce lint and dust, use
continuous fan operation and keep return vents unrestricted to
create an efficient airflow.
MAINTENANCE
It is very important that the scheduled maintenance be done
by the home owner. If the collecting pads are not changed
on a regular basis, the el ectronic air cleaner will not operate
effectively.
Injury or electric shock could result. Make sure to turn fur nace off before performing any maintenance or removing
any components. Unplug power supply cord from electronic air cleaner before removing from filter rack.
Connecting the electronic air cleaner to a higher voltage
power supply will cause damage to the electrical components of the electronic air cleaner. Do not connect to any
power source higher than 30-V .
4. Route the power cord to the electronic air cleaner
installation location. Plug the power cord into the high
voltage power supply box of the electronic air cleaner.
When power is provided to the electronic air cleaner,
the green high voltage power supply light will be on.
OPERATION
To verify operation, check the high voltage power supply
light on the power supply box. The green light should be on at
all times when the power cord is plugged in. When the collecting pads need to be replaced, the orange light on the powe r
supply box will be lit. Refer to the Collecting Pad Replacement
section on this page.
For maximum performance of the electronic air cleaner,
these steps should be followed:
• run your heating/cooling system fan continuously
• remove furniture or carpets which block return air grilles
throughout your house, so that air moves freely to the
furnace
• check for proper operation of the blower fan on the
furnace
• ensure that the air cleaner is not clogged.
NOTE: If one terminal of power source
is grounded, hook the white stripe wire
to this terminal
Collecting Pad Replacement —
The collecting pads
will need to be replaced 3 to 4 times a year, depending on the
amount of contaminants in the air. If the collecting pads or
mesh screens become clogged, airflow through the system may
be restricted. This may cause service problems with the furnace
or air conditioner. Check the orange plugged filter indicator
light on the electronic air cleaner.
T o replace the collecting pads:
1. Turn off furnace fan.
2. Disconnect power cord from the electronic air cleaner.
See Fig. 3.
3. Remove electronic air cleaner from filter rack. See
Fig. 4.
4. Lay the electronic air cleaner down. Open up the
frames so the collecting pads are exposed. See Fig. 5.
NOTE: If required, use the key to open the 5 corner
fasteners on the electronic air cleaner frames. See
Fig. 6.
5. Remove the power bar. Remove and discard both collecting pads. See Fig. 5.
6. Vacuum the outside screens to remove all dust and residue. See Fig. 7. The outside screens can be washed
with warm soapy water if needed. Be sure to dry
screens thoroughly before re-installing electronic air
collecting pads.
7. Install new collecting pads. Place power bar over collecting pad with carbon fibers. The power bar must be
in contact with the carbon fiber collecting pad in order
for the electronic air cleaner to operate correctly. See
Fig. 8. Never wash the collecting pads.
8. Close the electronic air cleaner frames together and
lock all 5 corner fasteners (if required). Make sure all
the components are properly placed.
9. Place the electronic air cleaner back in the filter rack.
See Fig. 9.
