Safety Guides
p 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.
p 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.
p A water softener will not improve other water prob-
lems such as acidity, tastes and odors, or iron other
than clear water iron.
p 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 disinfection before or after the system.
p 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.
* The capacity to reduce clear water iron is substantiated
by Water Quality Association test data.
p Use only lead-free solder and flux for all sweat-solder
connections, as required by federal codes, when
installing soldered copper plumbing.
p Use care when handling the water softener. Do not
turn upside down or drop.
p Avoid installing in direct sunlight. Excessive heat may
cause distortion or other damage to non-metallic parts.
p 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 reducing valve in the water supply pipe to the softener.
p Temperature of the water supply to the softener must be
between 40°F and 120°F. Do not install on hot water.
p If installing the water softener outdoors, do not locate
where it will be exposed to wet weather, direct sunlight
or extreme hot or cold temperatures.
p This softener works on 24 volt, 60 Hz electrical power
only, supplied by a direct plug-in transformer (included). 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 10VA
transformer.
p This water softener has a non-metallic valve system.
Installing it on metal plumbing will break electrical
continuity, which may interrupt grounding for the
home. You must restore electrical continuity in your
metal plumbing system (See Page 12).
European Directive 2002/96/EC requires all electrical and electronic
equipment to be disposed of according to Waste Electrical and Electronic
Equipment (WEEE) requirements. This directive or similar laws are in
place nationally and can vary from region to region. Please refer to your
state and local laws for proper disposal of this equipment.

Specifications & Performance Claims
This model is efficiency rated. The efficiency rating is valid only at the minimum salt dose. The softener has a
demand initiated regeneration (D.I.R) feature that complies with specific performance specifications intended to minimize the amount of regenerant brine and water used in its operation.
This softener has a rated softener efficiency of not less than 3,350 grains of total hardness exchange per pound of salt
(based on sodium chloride) and shall not deliver more salt than its listed rating or be operated at a sustained maximum service flow rate greater than its listed rating. This softener has been proven to deliver soft water for at least ten
continuous minutes at the rated service flow rate. The rated salt efficiency is measured by laboratory tests described
in NSF/ANSI Standard 44. These tests represent the maximum possible efficiency that the system can achieve.
Operational efficiency is the actual efficiency after the system has been installed. It is typically less than the rated
efficiency, due to individual application factors including water hardness, water usage, and other contaminants that
reduce a softener's capacity.

Maximum Drain Flow Rate 2.0 gpm
26,900 @ 7.9 lbs.
32,100 @ 13.3 lbs.
* Capacity to reduce clear water iron is substantiated by WQA test data. State of Wisconsin
requires additional treatment if water supply contains clear water iron exceeding 5 ppm.
** Intermittent flow rate does not represent the maximum service flow rate used for detemi-
ning the softener’s rated capacity and efficiency. Continuous operation at flow rates
greater than the service flow rate may affect capacity and efficiency performance.
This system conforms to NSF/ANSI Standard 44 for the specific performance claims as verified and substantiated by test data.
Variable Salt Dose: The salt dose is selected by the electronic controls at regeneration time
based on the amount needed.

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 temperature 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 warranty 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
near the softener to plug in the transformer
(See Fig. 4). Be sure the outlet and transformer are
in an inside location, protected from wet weather.
Use a continuously “live” outlet, which cannot 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 elements, 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.
Installation
INSTALL SINGLE BYPASS VALVE AND/OR THREADED INSTALLATION ADAPTORS
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.

SINGLE BYPASS VALVE:
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.

materials 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.
