UNPACKING -- This owners manual
was on a cardboard packing piece. On
the same cardboard piece are all the
small parts you will need to install the
softener (not including plumbing pipe
and fittings). So you don't lose any parts,
keep them on the cardboard until you
are ready to use them. A 20 foot roll of
drain hose is also included. Remove all
other cardboard pieces, foam packings,
tape, etc., from the softener and discard.
Check the softener for shipping dam-
age. Ifyou find damage, call your Sears
store for help.
Use care when handling the softener,
DO NOT turn upside-down. DO NOT
drop, or set on sharp objects that will
make ahole in the bottom.

• Your water softener will remove hardness
minerals and "clear water" iron from water, up to
the limits shown on page 28. It will not remove
other types of Iron, acids, tastes and odors, etc. It
will not purify polluted water or make it safe to
drink.
• Check with your local public works depart-
ment for plumbing, electric and sanitation
codes. You must follow their guides as you
install your softener.
• Use only LEAD-FREE SOLDER AND FLUX, J
as required by Federal and State codes, when
nsta ng so dered copper p umbing.
• Protect the softener and piping from freezing.
Damage from freezing voids the softener war-
ranty. See page 23.

HELPFUL INFORMATION
basics of plumbing. You can get a low cost book
If you know little about plumbing skills, we sug-
gest you get a book on the subject. There are
many good books for do-it-yourselfers on the
from Sears Plumbing and Heating departments
that will help you. Some basic sweat soldering tips
are on page 29 of this manual.

WATER SYSTEM TESTS
HAS YOUR WATER SUPPLY HAD A CHEMICAL
ANALYSIS? Sears has many kinds of water
treating units (see page 6) to correct different
water problems. To know the kind and size of unit
you need, you must first know what elements are
in your house water supply. A chemical analysis
shows the type and amounts of elements inwater.
If your water needs analysis, call or write your
nearest Sears store for help.
CHECK YOUR WATER PRESSURE -- For your
softener to work right, a water pressure of no lower
than 20 pounds per square inch (psi) is needed
in the house water pipes. The highest pressure
,&allowed in the water pipes is 120 psi. If pressure
is over 120 psi, buy and install a pressure reduc-
ing valve in the water inlet pipe to the softener.
NOTE: If water pressure during the day is 100 psi
or more, pressure during the night may go over
120 psi.
If you have a well water system, look at the
pressure gauge to find the water pressure. Call
your local water department if you have city water.
They willtell you what the water pressure is where
you live.
CHECK YOUR WATER FLOW RATE -- A water
flow of at least 3 gallons per minute is needed.
A lower flow will keep your softener from working
as well as it should. To make an easy check of
your flow rate, do the following. You will need a
1 gallon container (can; jar, pail, etc.).
1.
Fully open 2 cold water faucets close to the point
water enters the house.
.
With both faucets open, fill the gallon container
at ! faucet while looking at a watch or clock to
see how many seconds it takes.
.
Empty the container and go to the second faucet
(be sure BOTH faucets are still on). Fill the gallon
container at the second faucet and see how many
seconds it takes.
4.
Turn off both faucets. Now add the number of
seconds it took to fill the container at both faucets.
5.
A total of 80 seconds, or less, means the system
flow rate is good.

WHERE TO INSTALL THE SOFTENER
Think of the following points as you choose a
place to put your softener. (See FIG. 1).
• Place as close as possible to the pressure tank
(well water) or water meter (city water).
• Place as close as possible to a water drain such
as a floor drain, laundry tub, sump or standpipe.
A, Connect to the house main water pipe BEFORE
THE WATER HEATER. Temperature of water
going through the softener must not be more
than 120 F (49 C).
• Keep outside faucets on hard water to save soft
water and salt.
,k • DO NOT install in a place where the softener
could freeze. Freeze damage voids the warranty
by Sears, Roebuck and Co. (See page 23).
&• Put the softener in a place water damage is least
likely to occur if it develops a leak. Sears or the
manufacturer will not repair or pay for water
damage.
A•
A 120V electric outlet, to plug the transformer
into, is needed within 10 feet of the softener (the
softener has a 10 foot power cable). Be sure the
outlet and transformer are in an inside place,
to protect from wet weather.
&• When installing in an outside location, you must
take the steps necessary to assure the softener,
installation plumbing, and wiring, are as well
protected from the elements, contamination,
vandalism, etc., as when installed indoors.
A = Keep the softener out of direct sunlight. The
sun's heat can melt plastic parts.

PLAN HOW TO INSTALL YOUR SOFTENER
You must first decide how to run in and out pipes to
the flexible connectors* included with your softener.
Look at your house main water pipe at the point you
will connect the softener. Isthe pipe soldered copper,
glued plastic, or threaded galvanized or brass? What
is the pipe size? What kind of pipe and fittings is it
easiest f(_ryou to work with, and what tools do you
have?
Now look at FIG. 2 on page 8 and use it as a guide to
plan what materials you will need. As you plan your in
and out piping, keep in mind the following check list.
Then get all the materials you will need before you
start.
TOOLS, PIPE, FI'I-rlNGS AND
OTHER MATERIALS YOU WILL NEED
P' In and out pipes to the softener must be at least
3/4 in. size. Some local codes may tell you to use
no less than 1 in. pipe size (See Note on page 8).
I," Use copper, brass, or galvanized pipe and fittings.
Some codes may also allow CPVC plastic pipe.
_' Copper and galvanized pipe corrode fast when
connected together. Use pipe and fittings of the
same material.
P' ALWAYS install the bypass valve, which allows
you to turn off water to the softener, but still have
water in the house pipes.
Drain hose (7/16 in. inside diameter)is needed for
valve and salt tank drains. Twenty feet of hose is
included. If more hose is needed, you can buy it at
most Sears stores, or through Sears catalog,
Stock No. 42-3433.
If a rigid valve drain is needed to comply with
plumbing codes, you can buy the parts needed
(See page 11) to change the softener to a 1/2 in.

Take a length of the 7/16" inside diameter drain
hose and attach I end tothe drain fitting (FIG. 8).
Use a hose clamp to hold itin place. Putthe other
end of the hose (cut to length needed) over a
floor drain, into a laundry tub, sump, standpipe,
or other suitable drain. CHECK YOUR LOCAL
CODES.
IMPORTANT NOTES:
Leave an air gap of about 1-1/2" between the end
of the hose and the drain. This gap is needed so
you don't get a back-flow of sewer water into the
softener. DO NOT put the end of the hose into
the drain or connect without the air gap.

Place and support the hose so itdoes not kink or
have sharp bends. Tie or wire the hose in place
so water pressure will not make it "whip." Do not
pinch the hose shut. THE SOFTENER WILL
NOT WORK IF THIS DRAIN HOSE IS
PINCHED, PLUGGED OR CLOSED IN ANY
WAY.
Keep the hose lower than the drain fitting. (In
some homes, to get to a drain you must raise the
hose and run it over-head. If you need an over-
head drain, do not raise the hose more than 8'
above the floor. A copper drain tube is best to
use...see below.)
COPPER DRAIN TUBE: The plumbing codes where
you live may say that you must use a copper valve
drain tube. A copper tube is also best to use for an
over-head drain. Use a copper drain tube if the soft-
ener is installed outside, or in the sunlight. Heat from
the sun makes many kinds of rubber or plastic hose to
soften and close up,
To adapt a copper drain tube to the softener, use a
hacksaw to cut the barbed end from the drain fitting
as FIG. 9 shows. Buy a compression fitting (1/4 in.
female pipe threads x 1/2 in. O.D. tube) and tube from
Sears, or your local hardware store.
