1D. SANITIZING THE WATER SOFTENER
Care is taken at the factory to keep your water
softener clean and sanitary. Materials used to make
the softener wilt not infect or contaminate your
water supply, and will not cause bacteria to form or
grow. However, during shipping, storage, instal-
ling and operating, bacteria could get into the
softener. For this reason, sanitizing as follows is
suggested[] when installing_
1. The first time you sanitize your softener; be
sure to do all steps in the installation manual,
and on pages 5, 6 and 7 of this manual first.
2. Lift the salt hole cover and use a pai! or hose to
fill the salt storage tank with at least 3 gallons of
water.
=
_m
Remove the brinewel! cover (FIG_ 3) and pour
about 3/4 ounce of common 5.25% household
bleach (Clo_ox, Linco, BoPeep, White Sail,
Eagle, etc.) in the softener brinewe!l.
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.
-- It fills the salt tank to the water level need-
ed,
-- It gets all the air out of the resin tank.
-- It prepares the resin bed (see page 12) for
service.
[]
NOTES:
This recharge takes about 2 hours.
If the CLEAN feature is set to ON, a cleaning
backwash will occur first (CLEAdq and Bkwsh or
Rinse flashes in the display), before the sanitiz-
ing recha,ge_ Recharge takes about 2 hours and
15 minutes when the clean feabure is on.
You can sanitize the softener with or with-
out salt in the storage tank.
Recommended by the Water Quality Association. On
some water supplies, the water softener may need pe-
riodic disinfecting,

l l,l,i iii , .... lUUll,i ,,,i i , ' i i iii ....
Brine (salt dissolved in water) is needed for each
and every regeneration_ The water for making
b_ine is metered into the salt storage tank by the
softener. However, you must keep the tank filled
with salt.
Fill the tank with NUGGET or PELLET water
softener salt_ DO NOT use rock salts, as they have
dirt and sediments that will stop the softener' from
working.
Before filling, be sure the brinewell cover is in place
on the top of the brinewelI. Salt storage capacity is
shown on page 19_ Be sure to set the salt monitor
system (see page 10).
NOTES:
The salt monitor system (page 10) is calibrated to
the densi_ of nugget or pellet water softener salt.
The monitor will not work as accurately with other
types of salt including rock and solar,
In humid areas, it is best to fill the storage taixk
half-full, and to refill it more often, Salt bridging
(see page 15) occurs more often when conditions
are humid,
WATER SOFTENING SALT WITH IRON REMOV-
ING ADDITIVES -- Some salts have an additive to
help the softener handle iron in the water supply.
Although this additive may help to keep the
softener resin clean, it may also release corrosive
fumes that will weaken and shorten the life of some
softener parts_

Sodium information: Water softeners using sodium
ch!oride for regeneration add sodiuxn to the water,
Persons who are on sodium Iestricted 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 sodium_ That is
equivalent to eating 2q/2 slices of white bread°
Persons who are concerned about their drinking
water should consider a Kenmore Drinking Water
System that will remove or ieduce in excess of 90%
of the sodium and other drir_&ing water contami-
nants.
You have now finished the water softener start up. After the sanitizing recharge, on
page 8, the softener will be giving you soft water.

SALT MONITOR SYSTEM
The face plate timer has a low salt monitor with an
indicator light to remind you to refill the storage
tank with sail To set this monitor system:
1. Lift the salt hole cover and level the salt in the
storage tank,.
2. The salt level decal, on the brinewetI inside the
tar&, has numbers from 0 to 8 (see drawing on
page 9 and below)_ Observe the number the
leveled saIt is at or closest to,
3_
Now, press the SALT LEVEL ADJUST button
until black bars display up to the salt level
number'. For example, the pictures below show
the salt leve! at 6.
41
FinaIly, set the level you want the low salt
indicator light to come on. Press the SIGNAL
LIGHT ADJUST button until a (_) shows
opposite this number. In the example below,
the light will come one when the stored salt
drops to level Z At level 2, the storage tank is
about 1/3 full. This is the lowest you should
allow the stored salt level to drop to. To turn the
salt monitor off, press the button until OFF
shows.
NOTE:
For accurate salt monitor operation, always use
nugget or pellet water softener salt. See page 9.

2B. SOFT WATER SERVlCE AND REGENERATION
....... i .......... v,, ,i,i ........... . .....
SERVICE
When the softener is giving you soft water, it is
called "Service"° During service, hard water flows
through 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. 4)_ As hard water passes through the bed,
each bead attracts and holds the hardness miner-
als. This is called ion_exchanging. It is much like a
magnet attracting and holding metals_ Water with-
out 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 become
coated with hardness minerals and they have to be
cleaned. This cleaning is called regeneration or
recharge. Regeneration is started at 2:00 a.m. by the
electronic timer (see page t4)o It takes place in 5
stages or cycles° These are:
E] FILL [] BACKWASH
[_ BRINING [_ FAST RINSE
BRINE RINSE
NOTE:
If the CLEAN feature (page 7) is set to ON,
additional backwash and fast rinse cycles occur
before the fill cycle.

[] FILL: Salt, dissolved in water, is called brine.
Brine is needed to clean the hardness rninerals
from the resin beads, To make the brine, water
flows into the salt storage area during the fill stage
as shown in FIG. 5. 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,

{ J
2B. SOFT WATER SERVICE AND REGENERATION
.................................... J:l
'l ....
AUTOMATIC BYPASS
During the brining, brine rinse and backwash
cycles of regeneration, hard water goes through
the softener valve and to the house pipes_ If a faucet
is opened, hard water is there for your needs,
However, you should not use HOT water, if
possible, because the water heater will refill with
haiti water° The softener regenerates from 2:00 AM
to about 4:00 AM, (you can set anytime), a time
when not much water is used.
If you get up early in the morning and you can hear
the softener regenerating, change the time setting.
Set the recharge time to 12:00 AM or 1:00 AM (page
7), Then regeneiation will start and end that much
earlier 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 [] a
WATER METER, and [2] a COMPUTER,
[] WATER METER -- The water meter is in the
softener valve outlet. As water flows through the
meter, it sends electric pulses to the computer_ The
computer changes the pulses to a measure in
gallons of water.
[] COMPUTER -- The computer is part of the
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 7, 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 the most efficient

WHEN TO REFILL WITH SALT
The Salt Monitor System (see page 10) will turn on
the low salt light to warn you when to refill with
salt. Check for a low salt light a few weeks after you
install the softener, and every week after thatr
Always refill at about the #2 salt monitor level. At
this level, the tank is about 1/3 full. Never let the
softener use all the salt before refilling_ Without
salt, you will soon have haid water.
NOTE:
You will have a loss in softening capacity and may
get partly hard water if less than 10 inches (salt
monitor level 2) of salt is in the storage tank.
PLEASE SEE PAGE 9 FOR SALT FILLING DIRECTIONS.
BE SURE TO RESET THE SALT MONITOR, PAGE 10.
SALT BRIDGE
Sometimes, a hard crust or salt bridge forms in the
salt storage tank. It is usually caused by high
humidity or the wIong kind of salt. When the salt
bridges, an empty space forms between the water
and salt. Then salt will not dissolve (melt) in the
water 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 iL 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. 9. Make a pencil mark on
the handle, 1" or 2" below the top height of the rimr
Then, carefully push it straight down into the sail
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 iL Do not try to break the salt bridge by
pounding on the outside of the salt tank. You may
damage it.
If the wrong kind of salt made the bridge, take it
out. Then fill the tank with nugget or pellet salt
only.

3B. KEEPING THE WATER SOFTENER CLEAN
COVERS
To keep your new Kenmore water softener looking
nice, apply a coat of paste wax and repeat once a
year. When dusty, wipe it with a damp cloth to
keep it sparkling.
NOTE:
Never use cleaners having amanonia or abrasives.
They may scratch and dull the surfacer
NOZZLE & VENTURI
A clean nozzle and venturi (FIG. 10) is a must for
tile softener to work right° This small unit moves
brine from the salt storage tank to the resin tank
during regeneratJon_ If it becomes plugged with
sand, silt, dirt, etc,, tile softener will not work and
you wilt get hard water.
To get to the nozzle and vent-uri, remove the
softener top cover. Be sure the softener is in service
cycle (no water pressure at nozzle and venturi),
then turn off the cap from the nozzle and venturi
housing_ Do not lose the large o-ring seal Lift out the
screen support and screen, 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 screen&
Carefully replace all parts in the correct order_
Lubricate the o-ring seal with silicone grease or
Vaseline and place in position° Install and tighten
the cap, by hand only. Do not overtighten and
break the cap or housing.

IRON FROM THE RESIN BED
Your water softener takes hardness minerals (cal-
cium and magnesium) out of the watei: Also, it can
contro! some "clear water" iron. See maximum
allowed in the specifications on page 19. With clear
water iron, water from a faucet is clear when first
put into a glass. After 15 to 30 minutes, the water
begins 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 filter or other equipment is
needed. Your local Seazs 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° Sears 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_
