_JJJJJJJJJJJJJJJJ.

_JJJJ JJJJJJJJJJ. _JJJJ JJJJJJJJJJ.

_JJ_[JJJJJJJJJ"

• Your water softener will remove hardness minerals

and "clear water" iron* from water, up to the limits

shown on page 4-1. It will not remove other types of

iron, acids, tastes and odors, etc. It will not purify pol- luted water or make it safe to drink.

• Protect the softener and piping from freezing. Dam- age from freezing voids the softener warranty. See

page 3-3.

CAUTIONS

PLEASE READ AND COMPLY WITH THE FOLLOWING GUIDES TO PREVENT DAMAGE TO THE SOFTENER OR OTHER PROPERTY, PERSONAL INJURY, OR POS-

SIBLE FATAL SHOCK.

• THIS SOFTENER WORKS ON 24 VOLTS ONLY. BE SURE TO USE ONLY THE TRANSFORMER INCLUDED,

AND PLUG IT INTO A NOMINAL 120V, 60 CYCLE HOUSEHOLD OUTLET THAT IS GROUNDED AND PROPERLY PROTECTED BY AN OVERCURRENT DE- VICE SUCH AS A CIRCUIT BREAKER OR FUSE. IF

TRANSFORMER IS REPLACED, USE ONLY THE AU- THORIZED SERVICE CLASS, II, 24 VOLT, 10 VA

TRANSFORMER.

• Unplug the transformer right away if the power cable should become damaged or frayed. Make re- pairs, or replace transformer, before plugging back

into the power outlet.

• Always unplug the softener from electrical power before removing outer valve covers.

• This system is not intended to be used for treating water that is microbiologicaliy unsafe or of unknown quality without adequate disinfection before or after

the system.

*The capacity to reduce clear water iron is substantiated

by WQA test data.

California Efficiency Requirement

Your Kenmore Water Softener has a "High Effi- ciency" feature with an "ON" or "OFF" setting.

This softener setting is shipped in the "OFF" position, which utilizes the maximum rated ca-

pacity while most often achieving maximum salt efficiencies. When installing this unit in the State

of California, you MUST turn this setting to the "ON" position which may initiate more frequent recharges, however it will operate at 4000 grains per pound of salt or higher. If you wish to turn the Salt Efficiency feature "ON" (_ icon will show in display), follow the instructions in the Faceplate Timer Features, Sec-

tion 2 of this manual.

D. SANITIZE THE

Care is taken at the factory to keep your water soft- ener clean 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 (i9 when installing.

_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.

_lJ Lift the salt hole cover and use a pail to fill the

salt storage tank with up to 3 gallons of water (approximately 3 inches).

_J Remove the brinewell 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.

_1_ Open the bypass valve and press the RE-

CHARGE button and holdfor 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 needed.

• It gets all the air out of the resin tank.

• It prepares the resin bed (see page 2-4) for ser- vice and flushes residual chlorine from the soften-

er. Notes:

This recharge takes about 2 hours, depending on the salt type setting (page 1-4).

You can sanitize the softener with or without salt

in the storage tank.

Recommended by the Water Quality Association. On some

water supplies, the water softener may need periodic disinfecting.

SECTION 1 WATER SOFTENER START UP

E. ADDING SALT TO THE 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. You must keep salt in the tank, but because the wa-

ter softener is very efficient, it is not necessary to keep it full. In humid areas, it is best to fill the stor- age 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. Use 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 adding salt, be sure the brinewell cover is in place on the top of the brinewell. It is recommended to set the salt monitor system, although it is not re- quired for proper operation (see page 2-1).

POTASSIUM CHLORIDE, alternate to salt: The de- sign of this softener allows for the use of potassium chloride in place of salt (sodium chloride).

1) Place only one bag of KC1 in your softener at a time (the salt storage tank should contain no more than 60 pounds of KC1 at any one time).

2) A softener using KC1 should not be placed in areas with temperature fluctuations and high hu-

midity (KC1 will harden in these environments and may make the softener inoperable).

3) Check the brine tank and brinewell (black tube in salt storage tank) monthly. If hardening is present, pour small amounts of warm water on hardened areas until they loosen.

4) If you do use potassium chloride, see page 1-4 to set the timer for its use.

Note: The salt monitor system, page 2-1, is cali-

brated to the density of nugget or pellet water soft-

ener salt. The monitor will not work as accurately with other types of salt including rock and solar.

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.

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, and you drank 3 quarts of softened water, you would 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.

Press the RECHARGE button [_jd_;1 qnn_

Sometimes, a manually started regeneration (recharge) may be

desired, or needed. Two exam- ples are:

- You have used more water than usual (guests visiting) and you

may run out of soft water before the next timer started regenera-

tion.

- You did not refill the softener with salt before it was gone. After _1

you refill with salt:

You can start a regeneration right away, or you can set the timer to

regenerate at the next 2:00 AM (or other preset recharge time). Do the following.

SALT MONITOR SYSTEM

The faceplate timer has a low salt monitor with an indicator light to remind you to add salt to the stor-

age tank. To set this monitor system:

_Lift the salt hole cover and level the salt in the

storage tank.

_J_ The salt level decal, on the brinewell inside the

tank, has numbers from 0 to 8 (see drawing be- low). Observe the number the leveled salt is at

or closest to.

Now, press the SALT LEVEL ADJUST button until black bars display up to the salt level num- ber. For example, the pictures below show the

salt level at 6.

Finally, set the level you want the low salt indi- cator 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 2. 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.

NOW, Serv and Fill begin to flash

in the display. Upon reaching

and hold until *RECHARGE [I--_-- RECHAR'_7_

fill, the first cycle of regenera ....

tion, the flashing Serv turns off and Fill is on steady. RECHARGE continues to flash. This regeneration

will last for about 2 hours. After the 2 hours, you will have soft water again.

*Note:

If the CLEAN feature is set to ON, a cleaning back- wash (CLEAN and Bkwsh or Rinse flashes in the dis-

play, along with the minutes of the clean cycle re- maining) precedes the recharge.

RECHARGE TONIGHT

Press and release (do not hold) the RECHARGE button. RE-

CHARGE TONIGHT flashes in the display, and the softener be-

gins regeneration at the next preset recharge time. Press and release the RE-

CHARGE button once more if you decide to cancel the regeneration, and RECHARGE TONIGHT will not flash in the display.

RECHARGE TONIGHT

_]1 If you want to turn the salt monitor off, press the

SIGNAL LIGHT ADJUST button until OFF shows above.

Notes: If potassium chloride is used, be sure to adjust the

timer to the KC1 setting on page 1- 4. Your salt monitor is an estimate of your salt level; ac- curacy depends on the type of salt used and other regeneration characteristics.
