LOCATION
The
C
12
should
be
mounted
on
th€
Giling
near
the
center
of the
room.
Air is
drawn
into
the
bottom
of
the
C-12 and
discharged
in
4
directions.
Divide
larger
rooms
into
sections
and
use
an
C-12 in
the
crnter
of
each
section (Fig.
2).
TheC-]2
should
be installed
at the
c€iling in nearly
all applications.
This
is especially
important
when the
air
cleansr
is used
for
smoke
crntrol.
Visible smoke
contains
very
small
particles-so
srnall,
in fact,
tbat
they
are
not
noticaably
affected
by
gravity.
Smoke
lsrrelly
rises to
the ceiling
and
hangs
there.
If
the
C-12 must b€ installed
some
distanor away
from
ths ctiling,
make sura it is
at least 14
inches
[355
mm] away from
the ciling.
This
measure is neces-
sary
to reduce staining
of
th€ $iling
of lingring srnoky
air.
When the air
cl€aner is
right
against the
ceiling, the
air at the
ceiling is moving
too fast
to
deposit dirt
particlss.
Ovtr
14
inchc
[355
mm] from
the
cuiling,
ths
effsct is not
a
probhm.
But in thc spaoe
botsrern,
rlow
moving,
dirty air is
drawn into
thc aroa of ths
dircharg
outbts and
can
stain
a light
colorod c.iling.
FIG.
2-MOUNT
THE C.12
ON
THE
CEILING AT
THE
CENTER
OF THE
AREA
TO BE
CLEANED.
Check
the
existing
air
circulation in
the room.
The
C-12
should
be installed
so that it
aids the
sirculation
already
$tablished.
When airflow
patterns
are not
immediately
apparant,
obserw
the snpke froma
cigarette
in
various locations
within the room.
