Safety Guides

▲ Read all steps and guides carefully before installing

and using your new water softener. Follow all steps
exactly to correctly install. Failure to follow them
could cause personal injury or property damage.
Reading this manual will also help you to get all the
benefits from your water softener.

▲ Your Kenmore water softener will remove hardness

minerals from water. This is measured in grains per
gallon (gpg). It will also remove some clear water
iron*. This is measured in parts per million (ppm).
See the specifications page for the maximum limits
of hardness and iron removal.

▲ A water softener will not improve other water prob

lems such as acidity, tastes and odors, or iron other
than clear water iron.

▲ Do not attempt to use this product to make safe

drinking water from non-potable water sources. Do
not use the system on microbiologically unsafe water,
or water of unknown quality without adequate disin
fection before or after the system.

▲ Check with your local public works department for

plumbing and sanitation codes. You must follow
their guides as you install the system. Follow your
local codes if they differ with guides in this manual.
In Massachusetts, plumbing code 248-CMR 3.00 and

10.00 shall be adhered to. Consult with a licensed
plumber.

▲ Use only lead-free solder and flux for all sweat-solder

connections, as required by federal codes, when
installing soldered copper plumbing.

▲ Use care when handling the water softener. Do not

turn upside down or drop.

▲ Avoid installing in direct sunlight. Excessive heat may

cause distortion or other damage to non-metallic
parts.

▲ This water softener works on water pressures of 20 psi

(minimum) to 125 psi (maximum). If your house water
pressure is over the maximum, install a pressure reduc
ing valve in the water supply pipe to the softener.

▲ This softener works on 24 volt, 60 FIz electrical power

only, supplied by a direct plug-in transformer (includ
ed). Be sure to use the included transformer and plug
it into a nominal 120V, 60 cycle household outlet that
is properly protected by an overcurrent device such as
a circuit breaker or fuse. If transformer is replaced,
use only the authorized service. Class II, 24V lOVA
transformer.

▲ Do not install the water softener outside, or in extreme

hot or cold temperatures. Temperature of the water
supply to the water softener must be between 40°F
and 120°F. Do not install on hot water.

* The capacity to reduce clear water iron is substantiated

by Water Quality Association test data.

TYPICAL INSTALLATION

WHERE TO INSTALL THE WATER SOFTENER

Review the following points before you choose a place
to put your softener:

1. Place as close as possible to, but always downstream
from, the pressure tank (well water) or water meter
(city water).

2. Place as close as possible to a water drain such as a

floor drain, laundry tub, sump or standpipe (See Fig.

4).

3. Connect to the house main water pipe UPSTREAM

OF THE WATER HEATER (See Fig. 3). The tempera
ture of water going through the softener must not be
more than 120°F (49°C). Hot water will damage
inner softener parts. To reduce the risk of hot water
backup, piping between the softener and water
heater should be as long as possible.

4. Keep outside faucets on hard water to save soft

water and salt. See Fig. 4.

5. Do not install in a place where the softener could
freeze. Damage caused by freezing voids the war
ranty by Sears Brands Management Corporation.

6. Put the softener in a place where water damage is

least likely to occur if it develops a leak. Sears or

the manufacturer will not repair or pay for water

damage.

7. A grounded, 120V, 60 Hz. electrical outlet is needed
within 10 feet of the softener to plug in the trans
former (See Fig. 4). Be sure the outlet and trans
former are in an inside location, protected from wet
weather. Use a continuously “live” outlet, which can

not be accidentally switched off.

8. When installing in an outside location, you must take

the steps necessary to assure the softener, installation
plumbing, and wiring, are protected from the ele
ments, direct sunlight, contamination, vandalism, etc.

Plan Your Installation

CHECK YOUR WATER PRESSURE BEFORE INSTALLING

For your water softener to work properly, incoming
water pressure in your house pipes must be no lower
than 20 pounds per square inch (psi). The highest
allowable pressure is 125 psi. If pressure is above 125

psi, buy and install a pressure reducing valve in the
pipe supplying water to the softener’s inlet.

NOTE: If water pressure during the day is 100 psi or

more, pressure during the night may go above
125 psi.

nstallation

INSTALL SINGLE BYPASS VALVE AND/OR THREADED INSTALLATION ADAPTORS

SINGLE BYPASS VALVE:Complete the following steps to assemble the adaptors

and/or the included single bypass valve.

1. Close the shutoff valve on the house main water pipe,
near the water meter or pressure tank, to turn off the
water.

2. Shut off the gas or electric supply to the water

heater.

3. Open the highest and lowest water faucets in your

house. This will let water drain from the pipes.
Close faucets after water has drained.

4. Remove the top cover. Pull outward on the two tabs

to release top cover (see Fig. 5). The salt lid remains
attached to the top cover when removed. Set both
covers aside so they will not get scratched or broken.

Salt Lid

6. Push the bypass valve into the softener valve’s inlet

and outlet ports as far as it will go. Snap the two
large holding clips into place, from the top down as
shown (see Fig. 8).

CAUTION: Be sure the clips snap firmly into place so

the bypass valve will not pull out.

INLET AND OUTLET THREADED ADAPTORS:

7. Push the adaptors into the valve inlet and outlet

ports, or bypass valve ports, as far as they will go.
Both adaptors are the same and fit either port. Snap
the two large holding clips into place, as shown (see

Fig. 8).

CAUTION: Be sure the clips snap firmly into place so

the adaptors will not pull out.

5. Visually check and remove any foreign mate

rials from the valve inlet and outlet ports (see
Fig. 6). Carefully remove the two large plastic

clips (you will use them). Check to be sure
the turbine and support are firmly in place
(see Fig. 7).

NOTE: If you will not install the included bypass

valve because you will have a 3-valve
bypass in your plumbing, skip step 6, but
perform step 7.

CONNECT THE VALVE DRAIN HOSE

Take a length of 3/8” inside diameter drain tubing
(supplied) and attach one end to the drain fitting (see
Fig. n). Use a tube clomp from the ports bag to hold it
in place. Put the other end of the tubing over a floor
drain, into a laundry tub, standpipe, or other suitable
drain. Check your local codes.

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 o backflow of sewer water into the softener.
Do not put the end of the hose into the drain or con
nect without the air gap.

Locate and support the hose so it does not kink or hove
sharp bends. Secure the hose end so water pressure
does not cause the hose to “whip”. Tie or wire it in
place. Do not pinch the hose shut. The softener will
not work if this drain hose is pinched, plugged, closed
or restricted in any way. Direct drain flow down into
drain from drain line as flow could possibly overshoot
the drain cover.

Keep the hose lower than the drain fitting. In some
homes, to get to a drain you must raise the hose and
run it overhead. Do not raise the hose more than 8 feet
above the floor.

COPPER DRAIN TUBE: Local plumbing codes may
require the use a copper valve drain tube. A copper
tube is also best to use if running a drain line overhead.

To adapt a copper drain tube to the softener, purchase
a compression fitting (1/4" female pipe threads x 1/2"

0. D. tube) and tubing from your local hardware store.

CONNECT SALT TANK OVERFLOW HOSE

1. Locate the rubber grommet, adaptor elbow and tube
clamp (see Fig. 11) that are in the parts bag.

2. Push the grommet into the hole in the salt tank wall

so that half is inside and half is outside.

3. Push the larger end of the adaptor into the grommet.

4. Push one end of a length of 3/8" I.D. tubing (sup

plied) onto the tube adaptor, using a tube clamp
from the parts bag to hold it in place.

5. Put the other end of the tubing over the floor drain.

IMPORTANT: Overflow water must run down by gravity

through the tubing. Do not raise the tub
ing higher than the adaptor (see Fig. 11).

IMPORTANT: Do not connect this hose to the valve

drain hose you just installed (see above).

Both drains must have a separate hose.

NOTE: Drain Hose

(20 ft.) is included.
