WHAT THE ELECTRONIC AIR CLEANER DOES
Your High Efficiency Electronic Air Cleaner has been
designed to remove atmospheric and household dust, coal
dust, insecticide dust, mites, pollen, mold spores, fungi,
bacteria, pet dander, cooking smoke and grease, tobacco
smoke particles, and more down to 0.01 micron (0.01
micron = 1/2,540,000 of an inch).
BENEFITS
Helps provide relief for allergy or asthma suffering.
Helps prevent damaging black dust from staining walls
and furnishings, reducing the amount of time and
money spent cleaning and redecorating.
Helps protect heating/cooling equipment, prolonging the
operating efficiency.
Improves indoor air quality for a healthier environment,
year-round.
DESCRIPTION
The Electronic Air Cleaner is approximately 29 x 22 x 7
inches (73.6 x 55.9 x 17.8 cm). The unit is designed to be
wall or ceiling mounted in the main return air duct of a
forced air system. The intake grille is hinged to allow easy
access to the collecting cells and prefilters. The unit is rated
up to 2000 CFM (3398 m3/hr).
HOW IT WORKS
The High Efficiency Electronic Air Cleaner operates on
the principle of electrostatic precipitation. Millions of
airborne pollutants are carried through the return air duct of
the heating/cooling system and treated through three stages
of filtration.
The prefilter removes all large visible particles such as
lint. Smaller particles then pass through to a two-stage
electrostatic collecting cell. First, particles are given a
powerful positive electrical charge by the ionizing wires.
Certified for shock and electrical fire hazard only.
SAFETY CONSIDERATIONS
Read and follow instructions carefully. Follow all local
electrical codes during installation. All wiring must conform
to local and national electrical codes. Improper wiring or
installation may damage Air Cleaner.
Understand the signal words WARNING and CAUTION
which are present in the Owner’s Manual.
WARNING and CAUTION signifies a hazard which
could result in property damage, personal injury or death.
Installation and servicing of Electronic Air Cleaners
can be hazardous. Only trained and qualified service
personnel should install, repair, or service Electronic
Air Cleaners.

installed to the main return duct. For the unit to perform
properly, all the return air must pass through the
Electronic Air Cleaner.
In a wall installation, the unit must be installed
with the hinge down.
The return duct or transition should end slightly
behind the finished wall or framing. It should be
approximately 1/4 -1/2 inch (.63 - 1.27 cm) larger than the
Air Cleaner to allow the back of the unit to slip into the
duct when installing.
When the air duct does not fit the Air Cleaner
opening, a gradual transition is recommended to reduce
air turbulence through the Air Cleaner and to increase its
efficiency. There should not be more than 20º of
expansion used for the transition fitting.
Second, charged particles move into the collecting area
where they are attracted to a series of grounded plates.
Pollutants are held in this section like a magnet until
washed away during cleaning.
MAJOR COMPONENTS
Cabinet
The cabinet is constructed of 18 gauge steel, painted
with a tough powder-coated, scratch-resistant finish.
Holes are provided to facilitate mounting to the ductwork.
Access to the collecting cells and prefilters is through a
hinged door.
The access door is interlocked to cut power to the unit
when opened.
Important Installation Notes
When installing this Air Cleaner, it is important that
there is adequate air flow over the Air Proving Switch
(APS) sensor to activate the power supply when the fan is
operating. To ensure the flow of air over the sensor, the
attached ducting and transition to the Air Cleaner must be
sized and positioned correctly.
If rectangular duct is fitted to the back of the unit, it
must be placed so the opening is over the APS sensor or
transitioned deep enough to ensure air flow over the
sensor.
If round duct is used, it must be positioned over the
center of the opening in the back of the Air Cleaner and
should be at least 18” diameter. (See Fig. 2) If the
connecting duct back to the furnace or air handler is
smaller, a reducing collar should be used down the line to
reduce the duct to the required size. If the duct opening at
the rear of the Air Cleaner needs to be off-set because of
installation restrictions, it must be off-set so that the
position of the air opening is closer to the APS sensor.
With a round duct or under sized rectangular duct it is
important that the transition area between the back of the
Air Cleaner and the bottom of the duct opening is
maintained. A transition height of 10” will allow proper flow
across the sensor. (See Fig. 3)
The APS sensor can be adjusted further into the air
stream. This may be required if the APS sensor is not
directly in the air stream and a multi-speed or variable
Prefilters
The washable prefilters, measuring 11½ x 20 inches
(29.21 x 50.8 cm) are constructed of multi-layers of
aluminum mesh for maximum filtration of large particles.
Collecting Cells
The dual voltage collecting cells are constructed of
heavy gauge aluminum to resist rust and damage. The
first stage, the ionizing section, is charged at
approximately 7000 VDC. The collecting plates are
alternately grounded and charged at 4600 VDC. The
arrow on the cells indicates the direction of air flow which
must point toward the rear of the unit.
Electrical Compartment
The electrical compartment contains the system
switch, safety interlock, high voltage power board,
transformer, air proving switch and performance indicator
light.
INSTALLATION
Location
The Air Cleaner should be installed to the return air
duct in the living area of the home or office. It can be
installed either in a wall or ceiling, but not in the floor. This
unit will replace the existing return air grille currently

through the ducts. The Air Cleaner will not run if the
system fan is off. For proper operation, follow these
simple steps:
1. Run heating/cooling system fan continuously, and on
low speed if available.
2. Remove any furniture which may block the return air
grille, so that air moves freely to the furnace/ air
conditioner.
3. Check for proper operation of the system fan.
speed motor drops the air flow to a point the sensor will
not activate the power board.
Installation
Carefully remove the Air Cleaner from the carton.
Remove the cells and prefilters from the unit. Remove the
access door from the unit by removing the screw on the
end of the retaining link in the enclosure. Lower the
access door and remove the nuts securing the hinge to
the enclosure.
Remove the screws securing the electrical
compartment cover.
The hole in wall or ceiling should be made to fit the Air
Cleaner opening as closely as possible. The opening
should be framed to provide adequate support for the Air
Cleaner. Before mounting the Air Cleaner, cover the
framing and close the opening to within 1/4 in. (.63 cm) of
the dimension of the rear of the enclosure of the Air
Cleaner. Match the finish to the existing wall.
Mount the Air Cleaner into the framed hole and slide
into the duct until the front flange is flush with the wall.
Secure the Air Cleaner to the frame using sheet metal
screws. Do not overtighten screws as this may distort the
enclosure. Once the unit is secured to the wall, the access
door and retaining link can be replaced.
WHITE DUST
After installation of the Air Cleaner, you may notice
some white dust on tabletops and shelves. Most large
particles such as lint, are too heavy to remain airborne
and tend to settle quickly, never reaching the Air Cleaner.
This white visible dust is normally referred to as “clean
dust.” As the Air Cleaner is removing the dark and
staining particles from the air, the lint will also be cleaner.
Lint dust is most noticeable on dark furnishings; in
homes containing new carpeting; and where there is a lot
of household traffic from occupants and pets. To reduce
lint dust, use continuous fan operation and keep return
vents unrestricted to create an efficient airflow.
Note: The Air Cleaner does NOT produce more lint or
dust.
Wiring
Wiring should only be performed by qualified
personnel only. All wiring must comply with all applicable
codes and standards. The voltage of the power source
must match the voltage indicated on the Air Cleaner. The
Air Cleaner should operate ONLY when the system fan is
running. Make sure the Air Cleaner is properly grounded.
MAINTENANCE
It is important to follow a scheduled maintenance for
maximum performance of the Air Cleaner.
CAUTION
Damage to cells may occur if improperly handled or
washed. Do not wash cells in a dishwasher. Never use
any object to clean between the cell plates, as this may
cause damage to plates or ionizing wires. Never place
cell in oven to dry.The edges of the cell may be sharp handle with care.
WARNING
Electrical shock can cause injury or death. Be certain
main line disconnect switch is off before wiring.
Wire the Air Cleaner directly to the power source. The
APS will power the Air Cleaner when there is sufficient
airflow to activate the sensor.
Connect the black lead of the Air Cleaner to the line
side of power source. Connect the white lead to the
neutral side of the power source. Connect the green lead
to ground. See Fig. 5.
Cell And Prefilter Cleaning
The collecting cells and prefilters must be cleaned on
a regular basis for the Air Cleaner to function at its peak
efficiency. The frequency of cleaning will vary from one
location to another. On average, the cells should be
cleaned every 3 months.
1. Turn OFF power switch and wait 15 seconds. Open
access door and remove collecting cells and prefilters.
In a ceiling application open the door carefully.
2. Place cells in a laundry tub. Rinse with hot water and
spray completely with DAX Detergent (or a nonchlorine, non-corrosive, non-abrasive liquid household
detergent.) Allow detergent to run down both sides of
plates and ionizing wires. Let stand for 5 minutes and
rinse with hot water. Repeat process three times.
3. Rinse cells well with hot water (maximum 120°F/49°
C).
4. If dirt remains, let cells soak in a solution of DAX
Detergent and hot water for 30-60 minutes, then rinse.
5. Tilt cells on 45° angle on their short side, with arrows
pointing sideways. Allow to dry completely,
SYSTEM CHECK
Perform the following system check before operation.
1. Replace the prefilters and collecting cells. Close
access door and replace thumb screw.
2. Turn Air Cleaner power switch ON. Ensure system fan
is operating. The performance indicator light should
be lit showing that the Air Cleaner is operating.
Note: There may be some arcing or snapping sounds
from the collecting cells. This is normal when the unit is
new. In about 2 weeks, as the sharp edges of the cells
become smoother, the arcing will disappear.
OPERATION
The Air Cleaner will run as long as there is airflow

SERVICE
WARNING
Electronic Air Cleaners use high voltage (low
amperage). Only trained personnel should perform
service. Use caution. Electric shock can cause injury
or death. Disconnect power source before replacing
parts.
Testing Air Proving Switch (APS)
The APS sensor must protrude into the airstream to
work effectively. The sensor is very sensitive and
operation may be affected by cold temperatures, an air
exchanger, or a fresh air duct connected to the cold air
return near the Air Cleaner.
The APS uses a Triac in its output circuit, which
affects the voltage sine wave. Using a regular digital
voltmeter will give a false reading. To check the output
from the APS, use a true RMS (root mean square) meter
to measure the output at terminals 1 and 4 of the APS.
The output should be between 105 and 115 VAC,
depending on the airflow across the sensor.
A 125 volt neon lamp may be used to test the output
of the APS. Place the leads of the lamp across terminals 1
and 4 of the APS. If the lamp lights, the voltage is
sufficient for proper operation.
When the Air Cleaner is turned on without airflow, the
APS sensor heats up and within 30 seconds, opens the
circuit to turn off the power board. When the fan starts up
(the sensor is cooled), the circuit will close, the power
board is turned on, and the performance light will come
on.
If the power board fails to come on with the fan on,
check that the sensor is properly set in the airstream
behind the cell next to the switch. To check the APS for
Testing For High Voltage At Power Board
A high voltage meter capable of measuring up to
10,000 VDC is required to test the voltage.
1. Turn the Air Cleaner OFF. Remove cover from
electrical compartment.
2. The Air Cleaner should be ON with the door closed.
The unit fan should be running. The Air Cleaner
should be on at least 5 minutes to allow voltage to
stabilize.
3. Connect the ground of the high voltage meter to the
ground stud of the power board.
4. Check terminals HV1 and HV2 on the power board to
determine if voltage is present.
5. If no voltage is present, remove both cells from the Air
Cleaner and close access door.
a. Check the voltage at HV1 and HV2 again.
b. If voltage is present, the problem is with one of
the cells or the copper contact on the high voltage
tray.
c. With a flashlight, look into the cabinet to check
condition of the copper contacts.
d. If the contacts are not bent, replace one cell and
retest voltage. If cell is OK, test the other cell. If
the problem is with a cell, see Troubleshooting

Guide.
e. Check the APS to make sure that it is functioning
correctly.
f. Check the transformer to make sure power is
being supplied to the power board.
6. If there is voltage present, but the performance light
does not come on, replace light.
7. High voltage can be adjusted with high voltage
potentiometer if required.
6. Before replacing the transformer, check the resistance
across the power board 24 V input terminals, without
the transformer connected. Resistance should read
above 20K ohms with an analog meter and above 4M

8. Replace electrical compartment cover.
9. Return power to Air Cleaner. Test power board.
Note: Although the power board has been set before
shipping, it may be necessary to reset the voltage to the
correct load for optimum efficiency. Refer to Testing
Voltage At Power Board section for more information.
Testing Voltage Of Power Board
Voltage on the power board may drop below required
level when installation area is too damp, too cold, or if the
humidity is too high. Voltage on power board may be too
high when installation area is too dry or too hot, or home is
in close proximity to hydro towers or situated in remote
farm land areas. By adjusting the HV ADJ potentiometer,
the voltage can be set to optimum level. A high voltage
meter capable of measuring 10,000 VDC is required. To
test and adjust voltage level, perform the following
procedure:
1. Turn the Air Cleaner OFF.
2. Remove the electrical compartment cover.
3. Connect the ground of the high voltage meter to the
ground stud of the power board.
4. Turn ON the Air Cleaner and wait 5 minutes before
checking voltages to allow voltages on cells to
stabilize.

3. Remove the electrical compartment cover.
4. Attach the ground of the high voltage meter on to a
grounded area of the cell.
5. Place the tip of the high voltage probe on the cell
wire.
6. Turn the Air Cleaner ON.
7. Wait until the voltage stabilizes, then take a reading.
Adjust the HV ADJ potentiometer until the voltage
reading matches the voltage in Table 1. If the voltage
fails to stabilize or jumps up and down by more than
100 V, there may be a bad contact in the cell or a bad
contact between the cell contacts and the high
voltage contacts on the contact tray.
8. Test the voltage in both cells. They should read very
close to the same voltage.
9. Turn the Air Cleaner OFF. Replace the grilles,
electrical cover and prefilters.

Cleaner. Remove prefilters from track.
2. Close access door to Air Cleaner. Remove one of the
grilles from in front of each cell.
3. Turn the Air Cleaner ON.
4. Place a screwdriver between plates of the cell. There
should be an initial snap when the plates are shorted,
then no sound. If a hissing or ticking occurs, then
there is a bad contact either between the cell and the
high voltage contact or the contacts within the cell.
5. Test the ionizing wires by the same method, shorting
the wire to the grounded extended plate of the cell.
6. Turn the Air Cleaner OFF. Remove the cells and
check to see if the copper contacts along the bottom
of the cell channel are free.
7. With an ohmmeter, check continuity between the top,
outside disc contact and the first plate on the opposite

ATTENTION INSTALLER
IMPORTANT WIRING INFORMATION
This Electronic Air Cleaner is equipped with an Air Proving Switch (APS). The
recommended source for the input voltage to the Air Cleaner is from the same
source that is supplying the heating/cooling equipment, providing it is the same
voltage as the Air Cleaner. The Air Cleaner should be wired directly to the power
source. The APS will power the Air Cleaner when there is sufficient airflow to
activate the sensor.
If you wish to wire the Air Cleaner to the EAC / Accessories Module on the circuit
board of the furnace or air handler, ensure that there is 115 Volt output from
these terminals, when the unit is run manually and is running on low speed.
Some manufacturers do not supply full output voltage to the terminals in the low
speed mode, so the Air Cleaner will not function. The green Performance
Indicator Light will not turn on.
The Air Cleaner performs best when the system fan is on “FAN ON” or
“Continuous” mode, and is run on the low speed. Check the output of the
terminals with a volt meter when running on low speed, before wiring the Air
Cleaner to the circuit board.
The Air Cleaner must be wired to operate only when the system fan is on.
See page 4 of the Owner’s Manual for more information on wiring.
See page 3 for Important Installation Notes before installing.
