Wash
the element every 300 hours or after
five
dry-cleanings, whichever occurs first.
Seal
the small opening at the outer end of
the
ele-
ment,
then immerse completely in wann water
containing a little non-sudsing detergent.
Immedi-
ately raise the element
and
allow to soak
for
at
least
lS
minutes with the open end above the water
line.
After soaking, agitate
the
element in the water,
taking
care
not
to
allow dirty water outside
the
ele-
ment
to
splash over
to
the
inside.
Rinse
the element in clean, running water,
allow-
ing the water
to
run
from
the inside of the element
through
to the outside. If a hose is used,
do
not
use

IMPORTANT:
Do
not attempt to
dry
the element
with
heat or compressed air and do not
insta.ll
until
thoroughly dry as it may
rupture.
It is
recom-
mended that a
new
element
is
installed
at
this serv-
ice
and
the
washed element put aside for installa-
tion
at a subsequent service. The spare element
should
be
stored in a
dry
place and wrapped to
prevent dust contamination or
damage.
After drying thoroughly,
use
a light inside the ele-
ment
to
check for damage to the paper pleats. The
element should
be
discarded
if
pin pricks
of
light
can
be
seen or if there are areas of paper that
ap-
pear
thin.
If
the paper is bunched, the metal casing
distorted or the rubber end seal
is
loose or dam-
aged,
then
the
element should likewise
be
dis-
carded
and
a
new
one installed.
