HOW YOUR ELECTRONIC AIR CLEANER
WORKS
A process called “Electrostatic Precipitation”
traps airborne contaminants. The fandraws
particulate laden air successively through the
prefilter, the cell ionizing section and thecell
collector section. The ionizing sectionimparts
an electrical charge to the individualparticles
that are then drawn by electrostatic forces tothe
oppositely charged collector plates. Cleanedair
is then discharged back into theroom.
The electronic cells must be washedperiodically
to maintain efficientperformance.

Your SMOKEMASTER® Electronic Air Cleaneris
an advanced self-contained electronic air
cleaner. The model C-12 unit offers a lowcost,
energy efficient air cleaning solution with
minimal required maintenance. The
SMOKEMASTER® model C-12 is designed to be
installed in rooms with solid ceilings. Typical
installations include conference rooms,lounges,
offices, lunchrooms,etc.
Because it provides its own air circulation, your
SMOKEMASTER® unit may be used in almost
any application requiring the removal ofairborne
particulate contamination from an enclosed
space.
Recommended quantities of clean outdoor
ventilation air for various applications are
described in Table 2 of the ASHRAE Standard
62-89, “Ventilation for Acceptable Indoor Air
Quality.” ASHRAE (American Society of
Heating, Refrigerating and Air Conditioning
Engineers, Inc., Telephone #[phone])
notes that these recommended outdoor air
quantities may be reduced by the use ofclean,
recirculated air if the IAQ Procedure 6.2 isused.
Appendix E of ASHRAE 62-89 includes
recommendations for the use of clean,
recirculated air. However, in most cases,
adequate control of carbon dioxide generally
requires a minimum clean outdoor air quantityof
no less than 15 cubic feet of air per minuteper
person.
Additional ventilation may be required for toxic
contaminants. In any event, the air cleanermust
be used only in areas that are ventilated for
human occupancy in order to dissipate any
incidental generation ofozone.

Location
The C-12 should be mounted on theceiling
near the center of the room. Air is drawn intothe
bottom of the C-12 and discharged in four
directions. Divide larger rooms into sectionsand
use a C-12 in the center of eachsection.
The C-12 should be installed at the ceilingin
nearly all applications. This is especiallyimportant
when the air cleaner is used for smokecontrol.
Visible smoke contains very small particles –so
small, in fact, that they are not noticeablyaffected
by gravity. Smoke usually rises to the ceilingand
hangs there.
If the C-12 must be installed somedistance
away from the ceiling, make sure it is at least14
inches [355 mm] away from the ceiling. This
measurement is necessary to reduce stainingof
the ceiling of lingering smoky air. When theair
cleaner is right against the ceiling, the air atthe
ceiling is moving too fast to deposit dirtparticles.
Over 14 inches [355 mm] from the ceiling, the
effect is not a problem. But in the spacebetween,
slow moving, dirty air is drawn into the area ofthe
discharge outlets and can stain a lightcolored
ceiling.
Figure 5 - C-12 Mounting Location
Check the existing air circulation in theroom.
The C-12 should be installed so that it aidsthe
circulation already established. Whenairflow
patterns are not immediately apparent,observe
the smoke from a cigarette in variouslocations
within the room.
Figure 6 - C-12 InstallationDimensions
Ceiling Mounting
The C-12 is mounted by suspending itfrom
the ceiling.
The mounting holes in holes in the C-12are
spaced 16 inches [406.5 mm] between centersin
CAUTION!
1. Do not connect the power source until
after the electronic air cleaner is
mounted. Electrical shock and
equipment damage may result.
2. Be sure to turn off the air cleaner prior to
service or installation. The motor has an
automatic thermal overload so it will stop
when it is overheated. It will auto-
matically start after a cooling period.
3. Avoid electrical shock by being careful
when the air cleaner is turned on for an
electrical check. Also, be careful when
working near the air cleaner’s moving
parts.
4. Wear gloves when installing the air
cleaner to protect your hands from cuts.
IMPORTANT!
Read these instructions carefully. A
hazardous condition or damage to the
product could result if instructions are not
followed.

both directions. This makes it easy to fastenthe
air cleaner directly to the ceiling framework with8
inch lag screws. Leave space for the powercord
to run between the top of the C-12 and theceiling,
The power supply cord must not beconcealed
above ceilings or behindwalls.
Note in Figures 7 and 8 that the C-12 isnot
suspended from the top but rather from the
venturi plate, which is heavier metal and
designed to support the entire device.
Figure 7 –C-12 Lag Screw Placement
Figure 8 –C-12 Threaded RodPlacement
Be sure that you select a strong structuralpart
of the ceiling. Do not fasten it to a false ceilingor
to plaster or plaster-board. In some cases, itmay
be necessary to construct some type offraming
strong enough to support the weight of theC-12.
The C-12 may also be mounted using 3/8
in. [10 mm] diameter threaded steel rods
available in many hardware stores. Foursteel
rods will be required.
WALL MOUNTING
Two wall mounting brackets are usedto
support the C-12. They are included in an
accessory package along with a blank plateto
block off the outlet louvers on the side of theair
cleaner which will be against thewall.
The two brackets must be mounted on thewall
16 inches [406.5 mm] between centers so thatthe
long bolts will line up with the air cleanermounting
holes. The brackets should be securelyfastened
to the wall studs with lag screws. On masonry
walls, use appropriate screwanchors.
Use the blank metal plate to block off the
louvered outlet on the side of the air cleanerthat
will face the wall. Use the 2 screws with nutsand
washers to fasten this plate to thelouvers.

IONIZING WIRE REPLACEMENT
The ionizing wires in the charging section of the
electronic cell may break or becomedamaged.
Inspect the cell from the upstream side after
washing to make sure that none of the wires are
broken or out of position. During operation, a
broken or deformed wire generally causes ashort
to ground, possibly with visible arcing orsparking.
This condition, or any other short in theionizing
section of the cell, will cause the indicator lightto
go out.
Broken wires must be replaced for the aircleaner
to function effectively without arcing. Removeall
parts of the broken wire. If necessary, thecell may
be temporarily used with one wiremissing.
1. Use care to avoid damage to the spring
connector or other parts of the cell duringthe
installation.
2. Hook one end of the ionizing wire overthe
spring connector at one end of the cell.
3. Hold the opposite eyelet with aneedle-nose
pliers and stretch the wire the length of the
cell. Depress the opposite spring connector
and hook the eyelet over it (see Figure 18for
a reference).
