D. SANITIZE THE WATER SOFTENER
Ij:.! J: J: J: J:
WATER SOFTENER START UP
Care is taken at the factory to keep your water soft
ener dean and sanitary. Materials used to make the
softener will not infect or contaminate your water
supply, and will not cause bacteria to form or grow.
However, during shipping, storage, installing and
operating, bacteria could get into the softener. For
this reason, sanitizing as follows is suggested"^^
when installing.
[g The first time you sanitize your softener, be sure
to do all steps in the installation manual, and on
pages 1-2,1-3 and 1-4 of this manual first.
Note: Be certain the bypass valve is pulled out
to "service" position.
0 Lift the salt hole cover and use a pad to fdl the
__
salt storage tank with 3 gadons of water.
Remove the brinewed cover (FIG. 3) and pour
about 3/4 ounce, or 1 to 2 tablespoons, of com
mon 5.25%, unscented, household bleach (Clo-
rox, Linco, BoPeep, White Sail, Eagle, etc.) in the
softener brinewell. Replace the brinewell cover.
Press the ON/OFF-HOLD button and hold for 3
seconds to start a recharge. This first recharge
does several things.
• It draws the bleach into and through the softener
to sanitize it.
FIG. 3
salt hole cover
• It fills the salt tank to the water level needed.
• It gets all the air out of the resin tank.
• It prepares the resin bed (see page 2-3) for ser
vice and flushes residual chlorine from the soften
er.
Notes:
This recharge takes about 2 hours.
You can sanitize the softener with or without salt
in the storage tank.
(T
Recommended by the Water Quality Association. On some
water supplies, the water softener may need periodic
disinfecting.

E. ADDING SALT TO STORAGE TANK
Brine (salt dissolved in water) is needed for each
and every regeneration. The water for making brine
is metered into the salt storage tank by the softener.
However, you must keep salt in the tank, but it is not
necessary to keep it fuU. It is best to fill the storage
tank one quarter to one half full, and to refill it
more often. Salt bridging (see page 3-1) occurs
more often when conditions are humid and the tank
is filled to the top.

^
the tank with NUGGEl or PELLEl water soft
ener salt. DO NOT use rock salts, as they have dirt
and sediments that will stop the softener from
working.
Before filling, be sure the brineweU cover is in place
on the top of the brineweU.
If you choose Potassium Chloride (KCl) as a regen
erant, foUowing these suggestions wiU help give
you years of maintenance free service.
1) Place only one bag of KCl in your softener at a
time (the salt storage tank should contain no more
than 60 pounds of KCl at any one time).
2) A softener using KCl should not be placed in
areas with temperature fluctuations and high hu
midity (KCl wiU harden in these environments and
may make the softener inoperable).
3) Check the brine tank and brine well (black tube in
salt storage tank) monthly. If hardening is present,
pour smaU amounts of warm water on hardened
areas until they loosen.
4) If your softener does not have a KCl salt setting
you must increase your hardness setting by 25% to
ensure continuous soft water as in example below.

WATER SOFTENING SALT WITH IRON REMOV
ING ADDITIVES — Some salts have an additive to
help the softener handle iron in the water supply.
These salts may be used if your water supply has a
high iron content. It is recommended to use Sears
Resin Bed Cleaner 42- 34426, for periodic treatments
to keep your resin bed clean. This is available at
your local Sears store.
FIG. 4
Sodium information: Water softeners using sodium
chloride for regeneration add sodium to the water.
Persons who are on sodium restricted diets should
consider the added sodium as part of their overall
sodium intake. For example, if your water supply is
15 grains hard, you would have to drink 3 quarts of
softened water to consume 335 milligrams of so
dium. That is equivalent to eating 2-1/2 slices of
white bread.
Persons who are concerned about their drinking
water should consider a Kenmore Drinking Water
System that will remove or reduce in excess of 90%
of the sodium and other drinking water contami
nants.

B. SOFT WATER SERVICE and REGENERATION
j;j j:^.ì.ì j j j:^.ì.ì j j j:.
HOW YOUR WATER SOFTENER WORKS
SERVICE
When the softener is giving you soft water, it is
called "Service". During service, hard water comes
from the house main water pipe into the softener.
Inside the softener resin tank is a bed made up of
thousands of tiny, plastic resin beads (FIG. 5). As
hard water passes through the bed, each bead at
tracts and holds the hardness minerals. This is
called ion-exchanging. Water without the hardness
minerals (soft water) flows out of the softener and
into the house soft water pipes. After a period of
time, the resin beads hold all of the hardness miner
als they can, and cleaning with salt brine is needed.
This cleaning is called regeneration or recharge. Re
generation is started at 2:00 a.m. by the electronic
timer (see page 2-5). It takes place in 5 stages or
cycles. These are:
FILL
BRINING
BRINE RINSE
BACKWASH
FAST RINSE
REGENERATION
D FILL: Salt, dissolved in water, is called brine.
Brine is needed to clean the hardness minerals from
the resin beads. To make the brine, water flows into
the salt storage area during the fill stage as shown
in FIG. 6. Fill cycle length depends on how much
soft water making capacity you have used since the
last regeneration. As you use more water, fill time
increases so more brine is made. The greater
amount of brine cleans more hardness minerals
from the resin bed.

SECTION 2
B. SOFT WATER SERVICE and REGENERATION
j;j j:^.i.i j j j:^.i.i j j j:.
HOW YOUR WATER SOFTENER WORKS
BRINING: During brining, the brine is moved
from the salt storage area, into the resin tank. Inside
the resin tank, brine cleans hardness minerals from
the resin beads and they are discharged out the
drain. How much brine is needed to clean the resin
depends on:
- - the amount of service water used between regen
erations,
- - the amount of resin in the softener,
- - how fast the brine goes through the bed.
The nozzle and venturi (FIG. 7) make suction to take
brine from the salt tank and put it into the resin tank.
They keep the brine flow down to a very slow rate
to get the best resin cleaning with the least salt.
BRINE RINSE: After all of the brine is moved
into the resin tank, the brine valve closes. Water
keeps flowing the same way it did during brining
except the brine flow has stopped. Hardness miner
als and brine flush from the resin tank to the drain.
Brining and brine rinse together vary in the length
of time they take, relative to the fill cycle length.

FAST RINSE: Backwash is followed by a fast
flow of water down through the resin tank. The fast
flow packs the resin bed and gets it ready for return
to service (FIG. 9).
After fast rinse, the softener returns to service. Hard
water goes into the resin tank where the resin bed
again takes out the hardness minerals. Soft water
goes to the house soft water pipes.

HOW YOUR WATER SOFTENER WORKS
AUTOMATIC BYPASS
During the brining, brine rinse and backwash cycles
of regeneration, HARD water goes through the soft
ener valve and to the house pipes. If a faucet is
opened, hard water is there for your needs. Howev
er, you should not use
hot water, if possible, because
the water heater will refill with hard water. The soft
ener, as factory programmed, regenerates from 2:00
AM to about 4:00 AM, a time when not much water
is used.
If you start your day earlier in the morning (prior ro
4:00 AM), you may want to change the recharge
starting time. Set the recharge time to 12:00 AM or
1:00 AM (page 1-4). Then regeneration will start
and end that much earher and your water heater
will not refill with hard water if a hot faucet is
opened.
ELECTRONICS
Two main parts of the softener's electronics are Q]
a WATER METER, and m a COMPUTER.
m WATER METER—The water meter is in the soft
ener valve outlet. As water flows through the meter,
it sends electric pulses to the computer. The com
puter changes the pulses to a measure in gallons of
water.
Ej COMPUTER — The computer is part of the
faceplate timer circuit board. It is programmed to
know the softener's capacity (how many grains of
hardness minerals it will take out of the water before
a regeneration is needed). When starting the soften
er, page 1-4, you set it for the grains per gallon (gpg)
hardness of the water.
To find a regeneration pattern best for your needs,
the computer uses: (1) water usage from the meter,
(2) hardness setting, (3) softener capacity, and (4)
time since the last regeneration. The computer
always adjusts this pattern to your water using
habits. It works toward providing you with soft
water for the longest time and at the most efficient
salt usage.
Softening capacity is used as hard water goes
through the softener and hardness minerals are
removed. When the computer determines that only
enough capacity remains to provide soft water up to
the next regeneration starting time (2:00 AM, or as
otherwise set) it will schedule a regeneration.
RECHARGE TONIGHT displays until the
regeneration begins. When the regeneration begins,
RECHARGE TONIGHT goes off and RECHARGE
NOW flashes during the regeneration.

WHEN TO ADD SALT; Check the
salt level a few weeks after you
install the softener and every
week after that. Add salt to the
storage tank when the salt height
is reduced to about 1/4 full (see
note on page 1-6). Never let the
PLEASE SEE PAGE 1-6 FOR DIRECTIONS ON ADDING SALT.
softener use all the salt before adding. Without
salt, you will soon have hard water.
Note:
You will have a loss in softening capacity and may
get partly hard water if less than 10 inches of salt is
in the storage tank.
SALT BRIDGE
Sometimes, a hard crust or salt bridge forms in the
salt storage tank. It is usually caused by high hu
midity or the wrong kind of salt. When the salt
bridges, an empty space forms between the water
and salt. Then salt will not dissolve (melt) in the wa
ter to make brine. Without brine, the resin bed does
not regenerate and you will have hard water.
If the storage tank is full of salt, it is hard to tell if you
have a salt bridge. Salt is loose on top, but the bridge
is under it. The following is the best way to check for
a salt bridge.
Salt should be loose all the way to the bottom of the
tank. Hold a broom handle, or like tool, up to the
softener as shown in FIG. 10. Make a pencil mark on
the handle, 1" or 2" below the top height of the rim.
Then, carefully push it straight down into the salt.
If a hard object is felt before the pencil mark gets to
the top of the tank, it's most likely a salt bridge.
Carefully push into the bridge in a few places to
break it. Do not try to break the salt bridge by
pounding on the outside of the salt tank. You may
damage the tank.

B. KEEPING THE WATER SOFTENER CLEAN
NOZZLE & VENTURI
A clean nozzle and venturi (FIG. 11) is a must for the
softener to work right. This small unit moves brine
from the salt storage tank to the resin tank during re
generation. If it becomes plugged with sand, silt,
dirt, etc., the softener will not work and you will get
hard water.
To get to the nozzle and venturi, remove the softener
top cover. Be sure the softener is in service cycle (no
water pressure at nozzle and venturi).
1) Turn off the cap from the nozzle and venturi hous
ing.
2) Lift out the screen support and screen, do not lose
the large o-ring seal.
3) Then the nozzle and venturi. Wash and rinse the
parts in warm water until clean. If needed, use a
small brush to remove iron or dirt. Also check and
clean the gasket, flow plugs and screens.
Carefully replace all parts in the correct order. Lu
bricate the o-ring seal with silicone grease or Vase
line and place in position. Install and tighten the
cap, by hand only. Do not overtighten and break
the cap or housing.

IRON FROM RESIN BED
Your water softener takes hardness minerals (cal
cium and magnesium) out of the water. Also, it can
control some "clear water" iron. See maximum al
lowed in the specifications on page 4-1. With clear
water iron, water from a faucet is clear when first
put into a glass. After 15 to 30 minutes, the water be
gins to cloud or turn rust colored. A water softener
WILL NOT remove any iron which makes the water
cloudy or rusty as it comes from the faucet (called
red water iron). To take red water iron out of water,
or over the maximum of clear water iron, an iron fil
ter or other equipment is needed. Your local Sears
store has trained people to help you with iron water
problems.
If your water supply has clear water iron, even
though less than the maximum allowed, regular
resin bed cleaning is needed. Your local Sears store
has resin bed cleaner. Item No. 42-34426 for this.
Clean the bed at least every 6 months. If iron shows
up in the soft water before 6 months, clean more
often. Printed instructions are on the resin bed
cleaner bottle.

C. PROTECT THE WATER SOFTENER FROM FREEZING
If the softener is installed where it could freeze
(summer cabin, lake home, etc.), you must drain all
water from it to stop possible freeze damage. To
drain the softener:
Close the shut-off valve on the house main wa
ter pipe, near the water meter or pressure tank.
Open a faucet in the soft water pipes to vent
pressure in the softener.
Refer to FIG. 14 on page 4-1. Move the stem in
a 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.
Unplug the transformer at the wall outlet. Re
move the salt hole cover and the main cover.
Take off both drain hoses.
Carefully remove the large holding clips at the
softener inlet and outlet (see Key No. 66, on page
6-3). Separate the softener from the copper
tubes, or from the bypass valve.
Remove the brineweU cover and disconnect the
brine valve tubing at the nozzle and venturi as
sembly (see page 3-2). Lift the brine valve out of
the brinewell. Tip the brine valve upside down
to drain water.
FIG. 12
Drain All Water From Softener
Looking at FIG. 12, lay a piece of 2 inch thick
board near the floor drain. Move the softener
close to the drain. SLOWLY and CAREFULLY,
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 will break.
lip 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 rags to keep
dirt, bugs, etc. out.

C. WATER FLOW THROUGH THE SOFTENER VALVE
SERVICE CYCLE
Hard water enters the valve inlet port. Internal valve porting routes the water down and out the
top distributor, into the resin tank. Hard water is softened as it passes through the resin bed, then
enters the bottom distributor. Soft water flows back into the valve and out the valve outlet, to the
house soft water pipes.
FILL CYCLE
To begin a regeneration, the electronic timer energizes the circuit to the valve motor. The valve
motor rotates the rotor and disc and the valve cam until the position switch lever drops, to open
the motor circuit and position the valve in FILL. As the rotor and disc rotates, the port opens for

SERVICE TECH. INFORMATION
C. WATER FLOW THROUGH THE SOFTENER VALVE
BRINING AND BRINE RINSE CYCLES
After fill, timer/switch action allows the motor to turn the rotor and disc into BRINING position.
Water flow is directed to the nozzle. Suction, created by the nozzle and venturi, draws brine from the
salt storage tank and injects it into the resin bed via the bottom distributor. Flow continues out the top
distributor and to the drain. Hard water is available at the valve outlet.
When the brine valve doses to end brine draw, water flow continues in the same directions to slowly
RINSE brine from the resin bed and to the drain.
BACKWASH CYCLE
Timer/switch action again allows the motor to turn the
rotor & disc to place the valve in BACKWASH, stopping
water flow to the nozzle. Water is routed down and out
the bottom distributor, up through the bed, and out the
top distributor to the drain. The fast flow (controlled by a
flow plug in the drain fitting) flushes dirt, sediments,
iron deposits, remaining brine and hardness to the drain.

SERVICE TECH. INFORMATION
C. WATER FLOW THROUGH THE SOFTENER VALVE
FAST RINSE CYCLE
POSITION
During FAST RINSE, the rotor & disc is positioned so water flow enters the resin tank through the top
distributor, and exits through the bottom distributor, to the drain.
The electronic timer again energizes the motor to return the valve to service. As the valve rotates, the
position switch lever drops to open the circuit. The valve remains positioned in service until the
electronic timer initiates the next regeneration.
