HOW YOUR WATER FILTER WORKS
B. FILTERED WATER, SERVICE AND REGENERATION
IMPORTANT:
Sears
water
filters are sometimes
installed
alone
in the water
system,
but most
often other
water
treating
equipment
is needed.
Always
be sure to have your
water
tested
by a qualified
testing
labo-
ratory.
If you need
help, ask at your
Sears store,
or call the Kenmore
Water
Line, 1-800-426-9345.
TANNIN
WATER
Water
containing
tannin
has a yellowish
cast (even
after
softening
and/or
filtering).
Tannin
can be an
associated
cause
of yellow
stains
on washable
fab-
rics, china,
and plumbing
fixtures.
Tannins
(humic
acids)
are harmless
organics,
caused
by the water
passing
through
peaty
soil and decaying
vegeta-
tion.

SERVICE
When
the filter is providing
filtered
water,
it is
called
"Service".
During
service,
unfiltered
water
flows
from the house
main water
pipe
into the fil-
ter. Inside
the filter resin tank
is a bed made
up of
thousands
of tiny, plastic
resin beads.
As unfil-
tered
tannin
passes
through
the bed, each bead
attracts
and holds
the tannin
particles.
It is much
like a magnet
attracting
and holding
metals.
Water
without
the tannin
particles
flows out of the filter.

REGENERATION
FILL: Salt, dissolved
in water
is called
brine.
Brine
is needed
to clean the tannin
particles
from the
resin beads.
To make
the brine,
water
flows into
the salt storage
area during
the fill stage
as shown
below.

BRINING:
During
brining,
the brine
travels
from
the salt storage
area, to the resin
tank. Brine
causes
the resin
to release
the tannin
particles,
and they
are carried
to the drain.
The nozzle
and venturi
create
the suction
to move
the brine,
maintaining
a slow flow rate for maxi-
mum
cleaning.
After a period of time the resin becomes coated
with tannin particles and it has to be cleaned.
This
cleaning is called regeneration.
Regeneration
is
started at 12:00 AM (or other preselected
time) by
the timer, and consists of five cycles: (1) FILL, (2)
BRINING,
(3) BRINE RINSE, (4) BACKWASH,
(5)
FAST RINSE.
