Specifications & Performance Claims
This model is efficiency rated. The efficiency rating is valid only at the minimum salt dose. This system has a
demand initiated regeneration (D.I.R.) feature that complies with specific performance specifications intended to min-
imize the amount of regenerant brine and water used in their operation.
This water treatment system 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 system 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 lab-
oratory 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.
While testing was performed under standard laboratory conditions, actual performance of the system may vary based
on local water conditions. This system has been tested according to NSF/ANSI Standard 42 for the reduction of chlorine
taste and odor. The concentration of the indicated substance in water entering the system was reduced to a concentra-
tion less than or equal to the permissible limit for water leaving the system, as specified in NSF/ANSI Standard 42.
*Intermittent flow rate does not represent the maximum service flow rate used for determining the
conditioner’s rated capacity and efficiency. Continuous operation at flow rates greater than the
service flow rate may affect capacity and efficiency performance.
**Capacity to reduce clear water iron is substantiated by laboratory test data. State of Wisconsin
requires additional treatment if water supply contains clear water iron exceeding 5 ppm.
***Canada working pressure limits: 1.4 - 7.0 kg/cm

.
****Typical residential chlorine concentration is 0.5 to 1.0 ppm.
§ From independent laboratory test data.
This system conforms to NSF/ANSI Standards 42 & 44 for the specific performance claims as veri-
fied and substantiated by test data.

Before You Start
= The water softener requires a minimum water flow of 3 gallons per minute at the inlet. Maximum allowable inlet
water pressure is 125 psi. If daytime pressure is over 80 psi, nighttime pressure may exceed the maximum. Use
a pressure reducing valve if necessary (Adding a pressure reducing valve may reduce the flow). Failure to use a
pressure reducing valve may cause damage to the system, resulting in flooding and damage to property. If your
home is equipped with a back flow preventer, an expansion tank must be installed in accordance with local codes
and laws.
= The water softener works on 24V DC electrical power, supplied by a direct plug-in power supply (included). Be
sure to use the included power supply and plug it into a nominal 120V, 60 Hz household outlet that is in a dry
location only, grounded and properly protected by an overcurrent device such as a circuit breaker or fuse.
= Do not use this system to treat water that is microbiologically unsafe or of unknown quality without adequate dis-
infection upstream or downstream of the system.
European Directive 2002/96/EC requires all electrical and electronic equipment to be disposed of accord-
ing 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.

Water Conditioning Information
IRON
Iron in water can cause stains on clothing and plumb-
ing fixtures. It can negatively affect the taste of food,
drinking water, and other beverages. Iron in water is
measured in parts per million (ppm). The total* ppm of
iron, and type or types*, is determined by chemical
analysis. Four different types of iron in water are:
= Ferrous (clear water) iron
= Ferric (red water) iron
= Bacterial and organically bound iron
= Colloidal and inorganically bound iron (ferrous or
ferric)
Ferrous (clear water) iron is soluble and dissolves in
water. This water softener will reduce moderate
amounts of this type of iron (see specifications).**
Ferrous (clear water) iron is usually detected by taking
a sample of water in a clear bottle or glass.
Immediately after taking, the sample is clear. As the
water sample stands, it gradually clouds and turns
slightly yellow or brown as air oxidizes the iron. This
usually occurs in 15 to 30 minutes.
When using the softener to reduce Ferrous (clear
water) iron, add 5 grains to the hardness setting for
every 1 ppm of Ferrous (clear water) iron. See "Set
Water Hardness Number" section.
Ferric (red water), and bacterial and organically bound
irons are insoluble. This water softener will not
remove ferric or bacterial iron. This iron is visible
immediately when drawn from a faucet because it has
oxidized before reaching the home. It appears as
small cloudy yellow, orange, or reddish suspended
particles. After the water stands for a period of time,
the particles settle to the bottom of the container.
Generally these irons are removed from water by filtra-
tion. Chlorination is also recommended for bacterial
iron.
Colloidal and inorganically bound iron is of ferric or fer-
rous form that will not filter or exchange out of water.
This water softener will not remove colloidal iron. In
some instances, treatment may improve colloidal iron
water. Colloidal iron water usually has a yellow
appearance when drawn. After standing for several
hours, the color persists and the iron does not settle,
but remains suspended in the water.
SEDIMENT
Sediment is fine, foreign material particles suspended
in water. This water softener will not remove sedi-
ment. This material is most often clay or silt. Extreme
amounts of sediment may give the water a cloudy
appearance. A sediment filter installed upstream of
the water softener normally corrects this situation.
* Water may contain one or more of the four types of
iron and any combination of these. Total iron is the
sum of the contents.
** Capacity to reduce clear water iron is substantiated
by laboratory test data.

Installation Requirements
PLUMBING CODES
All plumbing must be completed in accordance with
national, state and local plumbing codes.
1-1/2”
air gap
In the state of Massachusetts: The Commonwealth
of Massachusetts plumbing code 248-CMR shall
be adhered to. A licensed plumber shall be used
for this installation.
AIR GAP REQUIREMENTS
A drain is needed for the water discharged from the
valve during the softener’s regeneration cycle (See
Figure 3). A floor drain, close to the water softener, is
preferred. A laundry tub, standpipe, etc. are other
drain options. Secure valve drain hose in place.
Leave an air gap of 1-1/2” between the end of the
hose and the drain. This gap is needed to prevent
backflow of sewer water into the water softener. Do
not put the end of the drain hose into the drain.

LOCATION REQUIREMENTS
Consider all of the following when selecting an installa-
tion location for the water softener.
= Do not locate the water softener where freezing
temperatures occur. Do not attempt to treat water
over 120ºF. Freezing temperatures or hot water
damage voids the warranty.
= To condition all water in the home, install the water
softener close to the water supply inlet, and
upstream of all other plumbing connections, except
outside water pipes. Outside faucets should remain
on hard water to avoid wasting conditioned water
and salt.
= A nearby drain is needed to carry away regenera-
tion discharge (drain) water. Use a floor drain,
laundry tub, sump, standpipe, or other options
(check your local codes). See "Air Gap
Requirements" and "Valve Drain Requirements"
sections.
= The water softener works on 24V DC electrical
power, supplied by a direct plug-in power supply
(included). Provide nearby a 120V, 60Hz electrical
outlet in accordance with NEC and local codes.
= Always install the water softener between the water
inlet and water heater. Any other installed water
conditioning equipment should be installed between
the water inlet and water softener (See Figure 4
below).
= Avoid installing in direct sunlight. Excessive sun
heat may cause distortion or other damage to non-
metallic parts.

Installation Requirements
VALVE DRAIN REQUIREMENTS
Using the flexible drain hose (included), measure and
cut to the length needed. Flexible drain hose is not
allowed in all localities (check your plumbing codes). If
local codes do not allow use of a flexible drain hose, a
rigid valve drain run must be used. Purchase a com-
pression fitting (1/4 NPT x 1/2 in. minimum tube) and
1/2" tubing from your local hardware store. Plumb a
rigid drain as needed (See Figure 6).
NOTE: Avoid drain hose runs longer than 30 feet.
Avoid elevating the hose more than 8 feet
above the floor. Make the valve drain line as
short and direct as possible.
INLET / OUTLET PLUMBING OPTIONS
Always install either a single bypass valve (provided),
as shown in Figure 7, or, if desired, parts for a 3 valve
bypass system (not included) can be purchased and
assembled, as shown in Figure 8. Bypass valves
allow you to turn off water to the softener for mainte-
nance if needed, but still have water in house pipes.
Use:
= Copper pipe
= Threaded pipe
= PEX (Crosslinked Polyethylene) pipe
= CPVC plastic pipe
= Other pipe approved for use with potable water
IMPORTANT: Do not solder with plumbing attached to
installation adaptors and single bypass
valve. Soldering heat will damage the
adaptors and valve.

TURN OFF WATER SUPPLY
1. Close the main water supply valve, located near the
well pump or water meter.
2. Shut off the electric or fuel supply to the water heater.
3. Open all faucets to drain all water from house pipes.
NOTE: Be sure not to drain water from the water
heater, as damage to the water heater ele-
ments could result.
ASSEMBLY
1. Kenmore
®
models are factory assembled. During
installation, unsnap and remove the top cover,
together with the salt lid (See Figure 11), to expose
the softener valve assembly. Set them aside to pre-
vent damage.
2. Install the brine tank overflow grommet and elbow
into the 13/16” diameter hole in the back of the salt
storage tank wall (See Figure 11).
MOVE THE UNIT INTO PLACE
1. Move the water softener into the desired location.
Set it on a solid, level surface.
IMPORTANT: Do not place shims directly under the
salt storage tank to level the softener.
The weight of the tank, when full of
water and salt, may cause the tank to
fracture at the shim.
2. Visually check and remove any debris from the
water softener valve inlet and outlet ports.
3. Make sure the turbine assembly spins freely in the
"out" port of the valve (See Figure 10).
4. If not already done, put a light coating of silicone
grease on the single bypass valve o-rings.
5. Push the single bypass valve into the softener valve
as far as it will go. Snap the two large holding clips
into place, from the top down as shown in Figures
12 & 13.
IMPORTANT: Be sure the clips snap firmly into place
so the single bypass valve will not pull
out.

COMPLETE INLET AND OUTLET PLUMBING
Measure, cut, and loosely assemble pipe and fittings
from the main water pipe to the inlet and outlet ports of
the water softener valve. Be sure to keep fittings fully
together, and pipes squared and straight.
Be sure hard water supply pipe goes to the water sof-
tener valve inlet side.
NOTE: Inlet and outlet are marked on the water sof-
tener valve. Trace the water flow direction to
be sure hard water is to inlet.
IMPORTANT: Be sure to fit, align and support all
plumbing to prevent putting stress on
the water softener valve inlet and outlet.
Undue stress from misaligned or unsup-
ported plumbing may cause damage to
the system.
Complete the inlet and outlet plumbing for the type of
pipes you will be using.

COLD WATER PIPE GROUNDING
CAUTION: The house cold water pipe (metal only)
is often used as a ground for the house
electrical system, The 3-valve bypass
type of installation, shown in Figure 8,
will maintain ground continuity. If you
use a plastic bypass valve at the unit,
continuity is broken. To restore the
ground, do the following:
1. Install a #4 copper wire across the removed section
of main water pipe, securely clamping it at both
ends (See Figure 14) - parts not included.
NOTE: Check local plumbing and electrical codes
for proper installation of the ground wire.
The installation must conform to them. In
Massachusetts, plumbing codes of
Massachusetts shall be conformed to.
Consult with your licensed plumber.
INSTALL VALVE DRAIN HOSE
NOTE: See valve drain options on pages 6 & 7.
1. Measure, cut to needed length and connect the 3/8"
drain line (provided) to the water softener valve
drain fitting. Use a hose clamp to hold the hose in
place.
IMPORTANT: If codes require a rigid drain line see
“Valve Drain requirements" section.
2. Run the drain hose (or a rigid line) to the floor drain.
Secure drain hose. This will prevent “whipping'' dur-
ing regenerations. Be sure to provide a 1-1/2”
minimum air gap to prevent possible sewer
water backup. See “Air Gap Requirements" sec-
tion.
NOTE: In addition to a floor drain, you can use a laun-
dry tub or standpipe as a drain point for this
hose.. Avoid long drain hose runs, or elevating
the hose more than 8 feet above the floor.
INSTALL SALT STORAGE TANK OVERFLOW
HOSE
1. Measure, cut to needed length and connect the 3/8”
drain line (provided) to the salt storage tank overflow
elbow and secure in place with a hose clamp.
2. Route the hose to the floor drain, or other suitable
drain point no higher than the drain fitting on the salt
storage tank (This is a gravity drain). If the tank
overfills with water, the excess water flows to the
drain point. Cut the drain line to the desired length
and route it neatly out of the way.
IMPORTANT: For proper operation of the water soften-
er, do not connect the water softener
valve drain tubing to the salt storage
tank overflow hose.
ADD WATER AND SALT TO THE SALT
STOR AGE TANK
1. Using a container, add about three gallons of clean
water into the salt storage tank.
2. Add salt to the storage tank. Use nugget, pellet or
coarse solar salts with less than 1% impurities.
PLUG IN THE POWER SUPPLY
During installation, the water softener wiring may be
moved or jostled from place. Be sure all leadwire con-
nectors are secure on the back of the electronic board
and be sure all wiring is away from the valve gear and
motor area, which rotates during regenerations.
1. Plug the water softener’s power supply into an elec-
trical outlet that is not controlled by a switch and is
approved by local codes.
NOTE: The water heater is filled with hard water and,
as hot water is used, it will refill with condi-
tioned water. In a few days, the hot water will
be fully conditioned. To have fully conditioned
hot water immediately, wait until the initial
recharge is over. Then, drain the water heater
(following instructions for water heater) until
water runs cold.
PROGRAM THE CONTROLLER
1. Install the softener’s top cover and salt lid.
2. Complete the Programming Steps on Pages 14 & 15.

Installation Instructions
SANITIZE THE WATER SOFTENER /
SANITIZE AFTER SERVICE
Care is taken at the factory to keep your unit clean and
sanitary. Materials used to make the unit will not infect
or contaminate your water supply, and will not cause
bacteria to form or grow. However, during shipping,
storage, installation and operation, bacteria could get
into the unit. For this reason, sanitizing as follows is
suggested* when installing.
1. Open the salt lid and pour about 3 oz. (6 table-
spoons) of household bleach into the softener
brinewell.
2 Make sure the bypass valve(s) is in the “service”
(open) position.
3 Start a recharge: Press the RECHARGE button and
hold for 3 seconds, until “Recharge Now” begins to
flash in the display. This recharge draws the sanitiz-
ing bleach into and through the water softener. Any
air remaining in the unit is purged to the drain.
4. After the recharge has completed, fully open a cold
water faucet, downstream from the softener, and
allow 50 gallons of water to pass through the sys-
tem. This should take at least 20 minutes. Close
the faucet.
*
Recommended by the Water Quality Association. On some
water supplies, the unit may need periodic disinfecting.
RINSE OUT CARBON FINES
Small particles of carbon filtration material are generat-
ed during manufacturing and shipping, which will exit
the media tank with the first water flow. These carbon
“fines” are not harmful, but give the water a gray color
and should be rinsed down the drain before any water
from the conditioner is directed to the home’s faucets
or water heater.
IMPORTANT: To avoid water or air pressure damage
to conditioner inner parts, and to flush
pipe chips or other residue from the
water pipes, be sure to do the following
steps exactly as instructed.
1. Make sure the water conditioner’s valve drain hose
is hooked up and the open end directed to a floor
drain, laundry tub or other suitable type of drain.
2. The system should be connected to electrical power.
3. Place bypass valve(s) in “bypass” position (see
Figures 7 & 8). On a single valve, slide the stem
inward to bypass. On a 3-valve bypass, close the
inlet and outlet valves and open the bypass valve.
4. Fully open the house main water pipe shutoff valve.
5. Initiate a regeneration by pressing and holding for 3
seconds the RECHARGE button (see Figure 16 on
page 14). The valve motor will start running and the
valve will advance to the “Fill” position.
6. After you hear the valve motor stop running (valve
in “Fill” position), press, but do not hold, the
RECHARGE button. The valve will advance to the
“Brine” position.
7. After you hear the valve motor stop running (valve
in “Brine” position), press, but do not hold, the
RECHARGE button. The valve will advance to the
“Backwash” position.
8. Once the unit is in backwash, place bypass valve(s)
in SERVICE, EXACTLY as follows:
a. Single Bypass Valve: Slowly, slide the valve stem
outward toward service, pausing several times to
allow the system to pressurize gradually.
b. 3-Valve Bypass: Fully close the bypass valve and
open the outlet valve. Slowly open the inlet valve,

Installation Instructions
TEST FOR LEAKS
To check for leaks, complete the following steps:
1. Fully open two nearby cold water faucets down-
stream from the water softener.
2. Observe steady flow from both faucets.
3. After about three minutes, open a hot water faucet
for about one minute, or until all air is expelled, and
then close this faucet.
4. Close both cold water faucets.
5. Check your plumbing work for leaks, and fix right
away if any are found. Be sure to observe previous
caution notes.
NOTE: If this procedure is performed on a new soften-
er, water coming from the taps may initially be
discolored. This normally occurs the first time
water runs through the resin bed. The discol-
oration will not last more than a few minutes.
RESTART THE WATER HEATER
1. Turn on the electricity or fuel supply to the water
heater and relight the pilot, if applicable.
NOTE: The water heater is filled with hard water and,
as hot water is used, it refills with conditioned
water. In a few days, the hot water will be fully
conditioned. To have fully conditioned hot
water immediately, wait until the initial recharge
(previous step) is over. Then, drain the water
heater (following instructions for water heater)
until water runs cold.

1. Press the r UP or s DOWN buttons to set the
hardness of your water supply, in grains per gallon.
The default is 25.
NOTE: If your water supply contains iron, compen-
sate for it by adding to the water hardness
number. For example, assume your water is
20 gpg hard and contains 2 ppm iron. Add 5
to the hardness number for each 1 ppm of
iron. In this example, you would use 30 for
your hardness number.

Sodium Chloride) or “KCl” (for Potassium Chloride)
should show in the display. Otherwise, press the
SELECT button several times until one of them does.
1. Press the
r UP or s DOWN buttons to set the
type of salt you will be using in your water softener.
The default is NaCl (standard Sodium Chloride
water softener salt). If you will be using KCl
(Potassium Chloride) instead, be sure to set salt
type to KCl. This setting adjusts the regeneration
cycle times to compensate for the different rate at
which KCl dissolves. See also Page 18 for more
information on salt types.

Press and release (do not hold) the RECHARGE but-
ton. “RECHARGE TONIGHT” will begin flashing in
the display, and the softener will begin regeneration
at the next preset recharge time (2:00 AM, or as set).
If you decide to cancel the regeneration before it
starts, press and release the RECHARGE button
once more. “RECHARGE TONIGHT” will stop flash-
ing in the display.
EXTRA RECHARGE
Sometimes, a manually initiated recharge (regenera-
tion) may be desired, or needed. Two examples are:
= You have used more water than usual (guests visit-
ing) and you may run out of soft water before the
next automatic regeneration.
= You did not add salt to the softener before it ran
out. Add salt to the softener before regenerating.
You can start a regeneration immediately, or you can
set the controller to regenerate at the next preset
recharge time (2:00 AM, or as set).
RECHARGE NOW
Press the RECHARGE button and hold for 3 sec-
onds, until the words “RECHARGE”, “Serv” and “Fill”
begin to flash in the display. The softener enters the
fill cycle of regeneration immediately. This regenera-
tion will take about 2 hours to complete. Then, you
will have soft water again.
NOTE: If the “Clean Feature” is set ON, the normal
regeneration cycle is preceded by a cleaning
backwash and rinse. The words “CLEAN”
and “Bkwsh” or “Rinse” flash in the display,
along with the minutes of the clean cycle
remaining.

CLEAN: This feature is beneficial on water sup-
plies containing iron and/or high amounts of sedi-
ments (sand, silt, dirt, etc.). When set to ON, a
backwash and fast rinse cycle will occur first, pre-
ceding the normal regeneration sequence. This
provides extra cleaning of the resin bed before it is
regenerated with the salt brine. To conserve water,
if your water supply does not contain iron or sedi-
ments, be sure this feature is set to OFF. The
default is OFF. Use the

beginning with Brine, the minutes of recharge remain-
ing before return to service appears in place of the
present time. When the valve is moving from one
cycle to another, both position indica tors are flashing.
POWER OUTAGE MEMORY
If electrical power to the softener is interrupted, the
time display is blank, but the electronic controller
keeps correct time for several hours. When power is
restored, you must reset the present time only if the
display is flashing. All other settings are maintained
and never require resetting unless a change is
desired. If the time is flashing after a long power out-
age, the softener continues to work as it should to

CLEANING THE NOZZLE & VENTURI
A clean nozzle & venturi (See Figure 41) is a necessity
for the water softener to work properly. This small
component creates the suction to move brine from the
brine tank, into the resin tank. If it should become
plugged with sand, silt, dirt, etc., the water softener will
not work, and hard water will result.
Nozzle & Venturi Disc
IMPORTANT: Be sure small hole in the gasket is cen-
tered directly over the small hole in the nozzle & ven-
turi housing. Be sure the numbers are facing up
Routine Maintenance
ADDING SALT
Open the salt lid and check the salt storage level
frequently. If the water softener uses all the salt
before you refill it, you will experience hard water.
Until you have established a refilling routine, check the
salt every two or three weeks. Always add if less than
1/4 full.
NOTE: In humid areas, it is best to keep the salt stor-
age level lower, and to refill more often to
avoid salt “bridging”.
Recommended Salt: Nugget, pellet or coarse solar
salts with less than 1% impurities.
Salt Not Recommended: Rock salt, high in impurities,
block, granulated, table, ice melting, ice cream making
salts, etc.
BREAKING A SALT BRIDGE
Sometimes, a hard crust or salt “bridge” forms in the
brine tank. It is usually caused by high humidity or the
wrong kind of salt. When the salt “bridges,” an empty
space forms between the water and the salt. Then,
salt will not dissolve in the water to make brine.
Without brine, the resin bed is not recharged and hard
water will result.
If the storage tank is full of salt, it is difficult to tell if
you have a salt bridge. A bridge may be underneath
loose salt. Take a broom handle, or like tool, and hold
it next to the water softener. Measure the distance
from the floor to the rim of the water softener. Then,
gently push the broom handle straight down into the
salt. If a hard object is felt before the pencil mark is
even with the top, it is most likely a salt bridge. Gently
push into the bridge in several places to break it. Do
not use any sharp or pointed objects as you may
puncture the brine tank. Do not try to break the salt
bridge by pounding on the outside of the salt tank.
You may damage the tank.
To get access to the nozzle & venturi, remove the
water softener’s top cover. Put the bypass valve(s)
into the bypass position. Be sure the water softener is
in soft water (service) cycle (no water pressure at noz-
zle & venturi). Then, holding the nozzle & venturi
housing with one hand, un screw the cap. Do not lose
the o-ring seal. Lift out the screen support and screen.
Then, remove the nozzle & venturi disc, gasket and
flow plug(s). Wash the parts in warm, soapy water
and rinse in fresh water. Be sure to clean both the top
and bottom of the nozzle & venturi disc. If needed,
use a small brush to remove iron or dirt. Do not
scratch, misshape, etc., surfaces of the nozzle & ven-
turi.
Gently replace all parts in the correct order. Lubricate
the o-ring seal with silicone grease and locate in place.
Install and tighten the cap by hand, while supporting
the housing. Overtightening may break the cap or
housing. Put the bypass valve(s) into service (soft
water) position.
Recharge the softener to reduce water level in the
tank. This will also assure that the softener is com-
pletely recharged and ready to provide softened water
again. Check the water level in the tank by looking
down the brinewell. If the water level does not drop
after a recharge, the problem has not been resolved.

PROTECT THE WATER SOFTENER FROM
FREEZING
If the softener is installed where it could freeze (sum-
mer cabin, lake home, etc.), you must drain all water
from it to stop possible freeze damage. To drain the
softener:
1. Close the shut-off valve on the house main water
pipe, near the water meter or pressure tank.
2. Open a faucet in the soft water pipes to vent pres-
sure in the softener.
3. Move the stem in the single bypass valve to
bypass. Close the inlet and outlet valve in a 3
valve bypass system, and open the bypass valve.
If you want water in the house pipes again, reopen
the shut-off valve on the main water pipe.
4. Unplug the power supply at the wall outlet. Open
the salt lid and remove the softener’s top cover.
Take off both drain hoses if they will interfere with
moving the softener into position over the drain.
5. Carefully remove the large holding clips at the sof-
tener inlet and outlet. Separate the softener from
the plastic installation adaptors, or from the bypass
valve.
6. Lay a piece of 2 inch thick board near the floor
drain (See Figure 42).
Floor Drain
FIG. 42
Wood Block
7. Move the softener close to the drain. Slowly and
gently, tip it over until the rim rests on the wood
block with the inlet and outlet over the drain. Do
not allow the softener’s weight to rest on the inlet
and outlet fittings or they may break.
8. Tip the bottom of the softener up a few inches and
hold until all water has drained. Leave the softener
laying like this until you are ready to use it. Plug
the inlet and outlet with clean rags to keep dirt,
bugs, etc. out.
CLEANSING FEATURE
The cleansing feature keeps larger particles of sedi-
ment from entering the home’s plumbing system. As
water passes through the softener, the larger sedi-
ment particles are collected in the integrated basket
and then rinsed to the drain before each regenera-
tion. The cleansing feature provides added protection
for water using appliances by reducing the chance of
larger particles entering the various products valves
and screens. The “Clean Feature” may be turned ON
to provide an extra backwash that will help keep the
cleansing screen clean. The default is OFF.
IMPORTANT: The cleansing feature is not intended to
replace pretreatment filtration. For
problem water applications, additional
sediment filtration is recommended.

play automatically returns if a button has not
been pressed for 4 minutes. To return to the
diagnostic display, repeat step 1, above.
AUTOMATIC ELECTRONIC DIAGNOSTICS
This water softener has a self-diagnostic function for
the electrical system (except input power and/or water
meter). The water softener monitors electronic com-
ponents and circuits for correct operation. If a mal-
function occurs, an error code appears in the display.
TURBINE OPERATION: If no water is flowing through
the softener, the turbine indicator displays three zeros.
When water is flowing, a 000 to 140 count repeats for
each gallon (3.8 liters) of water passing through the
turbine. To check for positive operation of the turbine
if zeros are shown, open a nearby soft water faucet
and observe the turbine count. If you don’t get a read-
ing in the display with faucet open, pull the sensor
housing from the valve outlet port (see Fig. 45). Pass

1. Press the SELECT button and hold it until the dis-
play changes twice to show the flashing model
code.
2. Press the
r UP button to display a flashing “SoS”.
3. Press the SELECT button, and the electronic con-
troller will restart.
4. Set the present time, hardness, etc., as described
on pages 12 & 13.
MANUAL ADVANCE REGENERATION
CHECK
This check verifies proper operation of the valve
motor, brine tank fill, brine draw, regeneration flow
rates, and other controller functions. Always make
the initial checks first, and perform the manually initi-
ated electronic diagnostics.
NOTE: The display must show a steady time (not
flashing). If an error code shows, first press
the SELECT button to enter the diagnostic
display.
1. Press the RECHARGE button and hold for 3 sec-
onds. RECHARGE begins to flash as the soften-
er’s valve advances from the service to fill position.
2. Shine a flashlight down the brinewell and observe
fill water entering the tank.
3. If water does not enter the tank, look for an
obstructed nozzle, venturi, fill flow plug, brine tub-
ing, or brine valve riser pipe.
4. After observing fill, press the RECHARGE button to
move the softener into brining. A slow flow of
water to the drain will begin. Verify brine draw from
FIG. 47
the brine tank by shining a flashlight into the
brinewell and observing a noticeable drop in the
liquid level.
5. If the softener does not draw brine:
= nozzle and/or venturi dirty
= nozzle and venturi not seated properly on gasket
= restricted drain (check drain fitting and hose)
= ineffective nozzle and venturi seal
= other inner valve problem (rotor seal, rotor &
disc, wave washer, etc.)
NOTE: If water system pressure is low, an elevated
drain hose may cause back pressure, stop-
ping brine draw.
6. Again press RECHARGE to move the softener into
backwash. Look for a fast flow of water from the
drain hose.
7. An obstructed flow indicates a plugged top distribu-
tor, backwash flow plug or drain hose.
8. Press RECHARGE to move the softener into fast
rinse. Again look for a fast drain flow. Allow the
softener to rinse for a few minutes to flush out any
brine that may remain in the resin tank from the
brining cycle test.
9. To return the softener to service, press RECHARGE
once more.

General Provisions
The above warranties are effective provided the water softener is operated at water pressures not exceeding
125 psi (8.8 kg/cm
2
), and at water temperatures not exceeding 120°F (49°C); provided further that the water
softener is not subject to abuse, misuse, alteration, neglect, freezing, accident or negligence; and provided
further that the water softener is not damaged as the result of any force of nature such as, but not limited to,
flood, hurricane, tornado or earthquake.
The limited warranty does not cover damage due to: (a) transportation, (b) storage, (c) improper use,
(d) failure to follow the product instructions or to perform any preventive maintenance, (e) modifications,
(f) unauthorized repair, (g) normal wear and tear, or (h) external causes such as accidents, abuse, or other
actions or events beyond Warrantor’s reasonable control. Use of aftermarket, used, or non-manufacturer
provided parts will void all warranties. Warranty does not cover failures due to improper product installation.
Warrantor is excused if failure to perform its warranty obligations is the result of strikes, government
regulation, materials shortages, or other circumstances beyond its control.
THERE ARE NO WARRANTIES ON THE WATER SOFTENER BEYOND THOSE SPECIFICALLY DESCRIBED
ABOVE. ALL IMPLIED WARRANTIES, INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY OR OF
FITNESS FOR A PARTICULAR PURPOSE, ARE DISCLAIMED TO THE EXTENT THEY MIGHT EXTEND BEYOND
THE ABOVE PERIODS. THE SOLE OBLIGATION OF WARRANTOR UNDER THESE WARRANTIES IS TO
REPLACE OR REPAIR THE COMPONENT OR PART WHICH PROVES TO BE DEFECTIVE WITHIN THE
SPECIFIED TIME PERIOD, AND WARRANTOR IS NOT LIABLE FOR CONSEQUENTIAL OR INCIDENTAL
DAMAGES. NO DEALER, AGENT, REPRESENTATIVE, OR OTHER PERSON IS AUTHORIZED TO EXTEND OR
EXPAND THE WARRANTIES EXPRESSLY DESCRIBED ABOVE.
Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above
limitation or exclusion may not apply to you. This warranty gives you specific legal rights, and you may have
other rights which vary from state to state. This warranty applies to consumer-owned installations only.
