D. SANITIZE THE WATER SOFTENER

_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.

_J|

Care is taken at the factory to keep your water softener 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 ® when installing.

_

Lift the salt hole cover and use a pat to fill the salt storage tank with up to 3 gallons of water.

Remove the bfineweU cover (FIG.

3) and pour about 3/4 ounce, or 1 to 2 tablespoons, mon 5.25%, unscented, household bleach of com-

(Clorox, Linco, BoPeep, White Sat, 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.

• 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 service and flushes residual chlorine from the softener.

Notes:

This recharge takes about 2-1 / 2 or 2- 3 / 4 hours, depending on the salt type setting (page 1-4).

You can sanitize the softener with or without salt in the storage tank.

E. FILL THE STORAGE TANK WITH SALT

Brine (salt dissolved in water) is needed for each and every regeneration.

The water for makingbrine is metered into the salt storage tankby the softener.

However, you must keep salt in the tank but it is not necessary to keep it full.

In humid areas, 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.

WATER SOFTENING SALT WITH IRON REMOVING

ADDITIVES -- Some sahs 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.

Fill the tankwith 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 brinewell.

Salt storage capacity is shown on page 4-1. Be sure to set the salt monitor system

(see page 2-1).

Note: The salt monitor system, page 2-1, is calibrated to the density of nugget or pellet water softener salt.

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

If you choose Potassium Chloride (KC1) as a regenerant, following these years of maintenance suggestions free service.

will help give you

II I li brinewell cover bdnewell

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 humidity

(KC1 will 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 small amounts of warm water on hardened areas until they loosen.

4) If your softener does not have a KC1 salt setting you must increase your hardness setting by 25% to ensure continuous soft water as in example below.

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 so-

dium 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 2-1 / 2 slices of white bread.

Persons who are concerned about their drinkingwater should consider a Kenmore Drinking Water System that will remove or reduce in excess of 90% of the sodium and other drinking water contaminants.

A. FACEPLATE TIMER FEATURES

• SALT MONITOR SYSTEM • EXTRA RECHARGE

Sometimes, a manually started regeneration desired,

(recharge) may be or needed.

Two examples are:

- You have used more water than usual (guests visiting) and you may run out of soft water before the next timer started regeneration.

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

After 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.

_I

_

The face plate timer has a low salt monitor with an indicator light to remind you to refill the storage tank with salt. To set this monitor system:

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 level at 6.

• RECHARGE NOW button and hold until *RECHARGE,

;

',

Serv and Fill begin to flash in the display.

Upon reaching fill, the first cycle of regeneration, the flashing Serv goes 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 backwash (CLEAN and Bkwsh or Rinse flashes in the display, along with the minutes of the clean cycle remaining) precedes the recharge.

_Lift the salt hole cover and level the salt in the storage tank.

_ m

The salt level decal, on the brineweU inside the tank, has numbers from 0 to 8 (see drawing below).

Observe the number the leveled salt is at or closest to.

Finally, 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 on 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 (see note on page 1-6).

Note:

Your salt monitor is an estimate of your salt level; accuracy depends on the type of salt used and other regeneration characteristics.

_Maximum days between regenerations: The faceplate timer automatically controls regeneration frequency (see page 2-5).

This provides the greatest operating efficiency, and under most conditions this feature will be left in its default mode.

However, you can modify this feature if you want to force a regeneration every set number of days.

For example, if your water supply contains iron and you want the softener to regenerate at least once every

few days to keep the resin bed clean, set the display

as typically shown above.

Setting is available from

1 to 15 days by using the UP and DOWN buttons.

5. Press SELECT to show the 12 HOUR display.

_CLEAN: This feature is beneficial on water supplies containing iron and/or high amounts of sediments (sand, silt, dirt, etc.). When set to ON, a backwash and fast rinse cycle will occur first, preceeding the normal regeneration sequence (see page 2-4).

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 sediments, be sure this feature is set to OFF.

3. Press SELECT again until the CLEAN TIME display shows.

B. SOFT WATER SERVICE and REGENERATION

REGENERATION 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 attracts 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 minerals they can, and deaning with salt brine is needed.

This cleaning is called regeneration or recharge.

Regeneration is started at 2:00 a.m.

by the electronic timer (see page 2-6).

It takes place in 5 stages or.

cycles.

These are:

[] FILL: Salt, dissolved in water, is called brine.

Brine is needed to dean 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.

' B. SOFT WATER SERVICE and REGENERATION

[] BRINING: During brining, the brine is moved from the salt storage area, into the resin tank.

Inside the resin tank brine deans 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 regenerations,

-- the amount of resin in the softener,

- -how fast the brine goes through the bed.

The nozzle and venturi (FIG.

HOW YOUR WATER SOFTENER WORKS

B. SOFT WATER SERVICE and REGENERATION

AUTOMATIC BYPASS ELECTRONICS

Dunng 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 hard water.

The softener, 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 prior to 4 AM, you may need 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 earlier and your water heater will not refill with hard water if a hot faucet is opened.

Two main parts of the softener's electronics are [] a WATER METER, and [] 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 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 softener, page 1- 4, you set it for the grains per gallon (gpg) hardness of the water.

To find a regeneration the computer uses: pattern

(1) water best usage for your needs, 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 removed.

When the computer determines minerals are that only enough capacity remains to provide soft water up to the next regeneration otherwise set) it will starting time schedule a

(2:00 AM, or as regeneration.

RECHARGE TONIGHT displays until the regeneration

When the regeneration begins,

* Note:

If the CLEAN feature is set to ON, a cleaning backwash (CLEAN and Bkwsh or Rinse flashes in the display, along with the minutes of the clean cycle remaining), precedes the recharge.

A. SALT: REFILLING STORAGE TANK, SALT BRIDGE

WHEN TO REFILL WITH SALT:

The Salt Monitor System (see page 2-1) will turn the low salt light on 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 that.

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 hard water.

After filling, reset the Salt

Monitor System, page 2-1.

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 1- 6 FOR SALT FILLING DIRECTIONS.

BE SURE TO RESET THE SALT MONITOR, PAGE 2-1.

N j_JJJJJJJJJJJJ_J.

_JJJJJJJJJJJ_J_J

SALT BRIDGE

Sometimes, a hard crust or salt bridge forms in the salt storage 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 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.

push tool into salt bridge to break

1" _ 2"

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.

pencil mark

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.

If the wrong kind of salt made the bridge, take it out.

Then fill the tank with nugget or pellet salt only.

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 regeneration.

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 coven 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 housing.

2) Lift out the screen support and screen, do not lose the large o-ring seal.

IRON FROM RESIN BED

Your water softener takes hardness minerals (calcium and magnesium) out of the water.

It can also control some "clear water" iron.

See maximum allowed 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 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 illter 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.

CARE OF YOUR WATER SOFTENER

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:

Drain All Water From Softener

[]Close the shut-off valve on the house main water 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.

Remove 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. 67, on page

6-5).

Separate the softener from the copper tubes, or from the bypass valve.

[]Remove the brinewell cover and disconnect the brine valve tubing at the nozzle and venturi assembly (see page 3- 2). Lift the brine valve out of the brinewell.

Tip the brine valve upside down to drain water,

[ drain wood block

I

[]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.

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 rags to keep dirt, bugs, etc. out.

D. CHECKLIST ... TO HELP YOU SAVE MONEY

If your water softener fails to work make the following easy checks.

Often, you will find what's wrong yourself and you won't have to call and wait for service.

If you do not find anything wrong, while making the checks, and your softener still does not work, call your Sears Service Department.

Note:

1. Also read ERROR CODE, page 2-3.

2. If an error code is not displayed, press and hold the SELECT button until the display changes.

Then, press the SELECT button again and hold until a flashing SR code appears.

It must show SR29 for UltraSoft 250 or

SR33 for UltraSoft 275. If any other number shows, the face plate computer is working on incorrect input and would probably be the cause of the problem.

To set SR29 or SR33, press either the UPI_ or DOWN(_ button.

When correct model code shows, press SELECT to return a flashing 12:00 AM display.

Reset the present time, hardness number, etc., pages 1-3 and 1-4.
