WHAT THE ELECTRONIC AIR CLEANER DOES
Your High Efficiency Electronic Air Cleaner has been
designed to remove tobacco smoke particles, cooking
smoke and grease, atmospheric dust, coal dust,
insecticide dust, mites, pollen, mold spores, fungi,
bacteria, viruses and more down to 0.01 micron (0.01
micron = 1/2,540,000 of an inch).
BENEFITS
Helps clear up a smokey environment quickly, so
customers can dine more comfortably.
Helps employees reduce suffering from irritated eyes,
nasal congestion and respiratory problems that lead
to absenteeism.
Helps prevent damaging black and greasy particles
from staining ceilings, walls and furnishings, reducing
the amount of housekeeping and redecorating costs.
Helps to lower energy bills by recycling air rather than
exhausting expensive heated or cooled air.
HOW IT WORKS
This Air Cleaner works on the principle of
"Electrostatic Precipitation". Millions of airborne pollutants
are drawn through the intake grill on the bottom of the Air
Cleaner and first pass through a Prefilter which removes
all large visible particles such as lint. Next, smaller
particles move to a two-stage electrostatic Collecting Cell
where they are given a powerful positive charge by the
ionizing wires. Charged particles then 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. Clean air is
then dispersed from the side grills in four directions
allowing superior air flow circulation.

MAJOR COMPONENTS
Description
The Electronic Air Cleaner is approximately 29½ x 27
x 14½ inches (75 x 68.6 x 37 cm). The unit is designed to
be mounted to the ceiling. The steel cover and intake grill
are hinged to allow easy access to the collecting cells
and power box. The unit is rated up to 1300 CFM (2210
m3/hr).
Cabinet
The cabinet is constructed of 20 gauge steel. The
external parts have a tough powder-coated, scratchresistant finish. The internal parts are galvanized steel.
Access to the collecting cells, power box and prefilters is
made by lifting the cover, sliding towards the front and
lowering.
The cover is interlocked to cut power to the unit when
opened.
Prefilters
The washable prefilters measuring 12½ x 20 inches
(31.75 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 7500 VDC. The collecting plates are
alternately grounded and charged at 5000 VDC. The
arrow on the cell indicates the direction of air flow which
must point up towards the fan motor.
Motor & Fan Blade
The motor is 1/12 HP, 1050 RPM, 3 speed, controlled
by a 3-position slide switch. The motor is thermally
protected. The fan blade is aluminum, 18 inches (45.7
cm) with a 16˚ pitch.
INSTALLATION
1. Read instructions carefully. Failure to do so may
result in product damage or injury.
2. Make sure the sizing is correct for your application.
3. Installation should be done by a knowledgeable
technician.
4. After installation, check out operation as provided in
these instructions.
Mounting
1. Remove the unit from the box with packing still on the
unit and lay it on its back, grill side up.
2. Release the cover by sliding towards the front of the
unit and lifting up.
3. Remove the "S" hook from each chain, tilt cover up,
and release from back.
4. Remove the cells and prefilters from the unit before
installing.
5. Holes are provided in the cabinet to accommodate
5/16 inch (8 mm) threaded rod. Threaded rod can be
attached to angle iron, laid across the joists, and
drilling holes through these supports. Pass threaded
rod up through the supports and secure with two nuts
and washers. This will allow adjustment of the unit so
that it is flush with the underside of the ceiling.
Leave enough room around the Air Cleaner for
removal of collecting cells and prefilters.
6. Replace the cells, prefilters and cover. Hook up the
safety chain to the cover.
Do not hang the unit with chain only. This will not

Wiring
WARNING
Electrical shock can cause injury or death. Be certain
main line disconnect switch is off before wiring.
All wiring must comply with applicable codes and
standards. See unit rating label for correct voltage and
amperage.
1. A knockout is provided on top of the unit, adjacent to
the wiring compartment. For convenience, a wall
switch may be installed near the Air Cleaner, in series
with the power source, to turn the unit on and off.
2. Remove the cover of the wiring compartment to
locate the input leads and ground stud. The Air
Cleaner must be grounded for proper operation and
safety.
3. Once the unit is mounted and wired, the cover can be
replaced on the hinge and the chain replaced on the
"S" hooks. Close the cover by sliding it forward, lifting
the cover over the front flange and sliding it back into
place.
For information on wiring the remote switch
control see page 7.
OPERATION & MAINTENANCE
Operation Check
1. With both cells and prefilters in place and the cover
closed, turn the system switch ON.
2. Adjust the fan speed with the slide switch. Insure the
unit functions on all speeds.
3. The performance light should be ON, which indicates
the power board is functioning properly.
4. If the unit is not functioning properly see the
"Troubleshooting Guide"
When the Air Cleaner is new it may arc or periodically
make "snapping sounds". A slight odor of ozone may be
noticeable. The arcing and odor are due to rough edges
and burrs on the cells. These symptoms will disappear
during the first few weeks of normal operation. The ozone
levels are well below government standards for indoor air
concentration.
Maintenance Schedule
The collecting cells and prefilters must be cleaned on
a regular basis for the unit to function at its peak
efficiency. The frequency of cleaning will vary from one
environment to another. The following is an average
wash cycle:
Stores, Offices, Computer & Conference Rooms = 4
Weeks
Cafeterias, Restaurants, Lounges = 3-4 Weeks
Bars, Bingo halls = 1-3 Weeks
The unit should be checked on a regular basis to
determine the frequency of cleaning required in each
location and a cleaning schedule established.
Cleaning
CAUTION
Make sure Air Cleaner switch is OFF before
performing any maintenance or removing any
components.
1. Turn off the system switch and wait 15 seconds for
high voltage to dissipate.
2. Open the cover and cell access door and remove
collecting cells and prefilters. Cell plates are sharp.
Handle with care.
3. Place cells in tub and spray completely with DAX
Detergent, allowing detergent to run down both sides
of plates and ionizing wires. Let sit for 5 minutes.
Rinse cells well with hot water (140ºF / 60ºC
maximum). Repeat washing process if necessary.
4. If dirt or nicotine remains on plates, let cells soak in
hot soapy water for 30 minutes. Never use any
instrument to clean the cell, as this may damage
the ionizing wires or bend cell plates.
5. Spray prefilters with DAX Detergent and rinse well.
6. To dry cells, tilt on 45º angle against wall with the
arrow pointing sideways. Allow to dry completely for
10-24 hours. Place in sunlight for faster drying time.
7. When the cells and prefilters are dry, place them
back into the unit. The arrow on the cell points up.
The red fiberboard on the cell should line up with the
contacts in the cabinet. Close door and cover. If the
cells arc when the switch is turned on or if the
performance light does not come on, then the cells
may be still wet. Allow more time for drying.
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.
