MAJOR COMPONENTS
Description
The Electronic Air Cleaner is approximately 24 x 28 x
15 in (61 x 71 x 38 cm) with 6 in (15.2 cm) of the unit
above the ceiling. The cover and exhaust grill which
remain below the ceiling are hinged to allow access to the
cell and power board. The unit is rated at 700 CFM (1190
m
3
/hr) on the highest speed setting.
Cabinet
The cabinet is constructed of 20 gauge steel. The
external parts have a tough powder-coated, scratch-
resistant finish. Access to the collecting cell, power box
and prefilter is made by releasing the latches of the cover
and allowing it to swing down.
The cover is interlocked to cut power to the unit when
opened.
Prefilter
The washable prefilter measuring 12.5 x 20 in (31.75
x 50.8 cm) is constructed of multi-layers of aluminum
mesh for maximum filtration of large particles.
Collecting Cell
The dual voltage collecting cell is 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 cells indicates the direction of air flow which
must point up towards the fan motor.
Motor and Fan Blade
The motor is 1/33 HP, 1050 RPM, 3-speed, controlled
by a 3-position slide switch. The motor is thermally
protected. The fan blade is 14 in (35.5 cm) with a 20
o
pitch.
Electrical Compartment
The removable power box contains the speed control,
system switch, high voltage power board, and
performance indicator light.
The interlock switch is located in the cabinet
body near the wiring compartment.
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

Mounting
1. Remove the unit from the box and lay the unit on its
back, grill side up.
2. Release the grill by pushing the levers, located in the
exhaust grill, toward each other and lift up.
4. Remove the ‘S’ hook from each chain, tilt cover up
until the cover releases from the back hinges.
5. Remove the cell and prefilter from the unit.
6. Holes are provided in the cabinet to accommodate
5/16 in (8 mm) threaded rod. Threaded rod can be
attached to the angle iron which is laid across the
joists, by drilling holes through these supports. Pass
threaded rod up through the supports and secure with
two nuts and washers. This will allow adjustment of

Fig. 2 — Coanda Air Flow
The Air Cleaner
creates a circular air
flow
pattern which
never allows air to
rest at the ceiling.
Blower and motor are
hidden above ceiling tiles
for
space conservation.
Advantageous for low
ceiling applications where
a larger unit would be
obstructive.
Hinged
cover provides
convenient access to grill,
prefilter, collecting cell and
electrical
compartment.
Safety interlock cuts power
when cover is opened.
Rear hinges permit smooth
release of cover for easy
installation.
Removable intake grill for
easy cleaning.
Heavy duty collecting
cell captures airborne
pollutants and simply
washes clean.
Washable,
aluminum
mesh prefilter catches
lint and large particles
before
they enter
collecting cell.
3-speed
fan control
(not shown) allows
adjustment of air flow
to activity level in room.
