Y Read all steps, guides and rules carefully before installing and using your new water soften-

er. Follow all steps exactly to correctly install. Failure to follow them could cause personal injury or property damage. Reading this book will also help you to get all of the benefits from your water softener.

Y Your Kenmore Water Softener will remove hardness minerals from water. This is measured

in grains per gallon (gpg). It will also remove some clear water iron*, barium and radium 226/228**. These are measured in parts per million (ppm). See the specifications page for the maximum limits of hardness and iron, barium and radium 226/228 removal.

Y A water softener will not improve other water problems such as acidity, tastes and odors, or

iron other than clear water iron. lt will not purify contaminated water, or make unsafe water safe to drink.

Y Check with your local public works department for plumbing, electric and sanitation codes.

You must follow their guides as you install your softener. Use only LEAD FREE SOLDER AND FLUX, as required by federal and state codes, when installing soldered copper plumbing.

Y Protect the softener and piping from freezing. Damage from freezing voids the softener war-

ranty. See how to protect from freezing on page 34.

CAUTION: Please read and comply with the following guides to prevent damage to the softener or other property, personal injury, or possible fatal shock.

Y This softener works on 24 volts only. Be sure to use only the transformer included.

Plug it into a nominal 120V, 60 cycle household outlet that is grounded and properly protected by an overcurrent device such as a circuite breaker or fuse. If transformer is replaced, use only the authorized service Class II, 24 volt, 10 VA transformer.

Y Unplug the transformer right away if the power cable should become damaged or frayed.

Make repairs, or replace the transformer, before plugging back into the power outlet.

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

Y This system is not intended to be used for treating water that is microbiologically 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.

** If conditioner is being used to remove barium and/or radium 226 and 228, please verify per-

formance by contacting 612-607-1700, ext. 6470 for testing treated water supply, or check the water testing section of your local phone directory.

European Directive 2002/96/EC requires all electrical and electronic equipment to be disposed of according 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.

Plan Your Installation

Typical Installation

1. Place as close as possible but always after, the pressure tank (well water) or water meter (city water). See Fig. 3.

2. Place as close as possible to a water drain such as a floor drain, laundry tub, sump or standpipe. See Fig. 3.

3. Connect to the house main water pipe BEFORE THE WATER HEATER. See Fig. 3. Temperature of

water going through the softener must not be more than 120°F (49°C). Hot water will damage

inner softener parts. To reduce the risk of hot water backup, piping between the softener and water

heater should be as long of a run as possible.

4. Keep outside faucets on hard water to save soft water and salt. See Fig. 3.

5. Do not install in a place where the softener could freeze. Damage caused by freezing voids the warranty by Sears, Roebuck and Co.

6. Put the softener in a place where water damage is least likely to occur if it develops a leak. Sears or the manufacturer will not repair or pay for water damage.

7. A grounded, 120V electrical outlet is needed within 10 feet of the softener. See Fig. 3. This is to plug in the transformer. The softener has a 10 foot power cable. Be sure the outlet and transformer are in an inside place, to protect from wet weather. Use a continuously “live” outlet, which cannot be accidentally switched off.

8. When installing in an outside location, you must take the steps necessary to assure the softener, installation plumbing, and wiring, are protected from the elements, contamination, vandalism, etc.

9. Keep the softener out of direct sunlight. The sun’s heat can melt plastic parts.

WHERE TO INSTALL THE WATER SOFTENER

Review the following points before you choose a place to put your softener.

Draw the plans for your “IN” and “OUT” piping here. Include all pipe, fittings and accessories you will use.

Make a list of all materials you will need and buy them before you begin to install the water softener.

FIG. 5

FIG. 4

Page 9

PIPE, FITTINGS, OTHER MATERIALS NEEDED

You must first decide how to run “in” and “out” pipes to the softener. Look at your house main water pipe at the point you will connect the softener. Is the pipe soldered copper, glued plastic, or threaded galvanized or brass? What is the pipe size? What kind of pipe and fittings is it easiest for you to work with, and what tools do you have?

Now look at the common plans for “in” and “out” piping on soldered copper. See Fig. 6. Use it as a guide to plan what materials you will need. Get all the materials you will need before you start.

Use Fig. 5 to make a plan drawing for your specific installation. “In” and “out” fittings included with the softener are 1” NPT threaded adaptors. You should maintain the same, or larger, pipe size as the water supply pipe, up to the softener inlet and outlet. Use copper, brass, galvanized or PVC plastic pipe and fittings for the “in” and “out” pipes. Be sure to check local codes.

Note: If converting from galvanized to copper pipe use approved dielectric insulating connectors.

ALWAYS install the bypass valve (that is included with the unit) or a three valve bypass. See Fig. 9 to13. Bypass valves let you turn off water to the softener if needed for repairs, but still have water in the house pipes.

Drain tubing (3/8” inside diameter), is needed for the valve and salt tank drains. See Fig. 16. If a rigid valve drain is needed to comply with plumbing codes, you can buy the parts needed (see Fig. 16) to change the softener to a 1/2 inch minimum copper tubing drain.

Read Before Beginning Installation

BEFORE INSTALLING CHECKS & TESTS

Your water supply needs to be checked for chemical analysis, water pressure and water flow rate. To accomplish this, complete the following steps:

Check Water’s Chemical Analysis: Sears sells a complete line of water treating equipment to correct various water problems. To be sure you have the proper type and size equipment, You must have your water tested. Your Sears store can give you a water test results for hardness, iron and acidity, and tell you what equipment you need. Simply take at least a 4 oz. sample of your water to Sears, and they will test it while you wait. If you need help to get your water tested, or if you have other questions about your water, ask at your Sears store.

NOTE: Add these readings to the Facts and Figure table on page 3.

Check Your Water Pressure: For your softener to work right, a water pressure of no lower than 20 pounds per square inch (psi) is needed in the house water pipes. The highest pressure allowed in the water pipes is 125 psi. If pressure is over 125 psi, buy and install a pressure reducing valve in the water inlet pipe to the softener.

NOTE: If water pressure during the day is 100 psi or more, pressure during the night may go over 125 psi. Adding a pressure reducing valve may reduce the flow.

NOTE: Add these readings to the Facts and Figure table on page 3.

If you have a well water system, look at the pressure gauge to find the water pressure. Call your local water department if you have city water. They will tell you what the water pressure is where you live.

NOTE: Add these readings to the Facts and Figure table on page 3.

Check your water flow rate: A water flow of at least 3 gallons per minute is needed. A lower flow will keep your softener from working as well as it should. Complete the following steps to make an easy check of your flow rate.

1. Fully open two cold water faucets close to the point water enters the house.

2. With both faucets open, fill a gallon container at one faucet while looking at a watch or clock to see how many seconds it takes.

3. Empty the container and go to the second faucet (be sure BOTH faucets are still on). Fill the gallon container at the second faucet and see how many seconds it takes.

4. Turn off both faucets. Now add the number of seconds it took to fill the container at both faucets.

5. A total of 90 seconds, or less, means the system flow rate is good.

NOTE: Add these readings to the Facts and Figure table on page 3.

NOTE: Codes in the state of Massachusetts require installation by a licensed plumber. For installation, use plumbing code 248CMR of the Commonwealth of Massachusetts.

2. Shut off the gas or electric supply to the water heater. See Fig. 7.

3. Open the highest and lowest water faucets in yourhouse. This will let water drain from the pipes. Close faucets after water has drained.

4. Remove the main cover. See Fig. 8. Pull outward on two (2) tabs to release.

The salt hole cover remains attached to the main cover when removed. Set both covers aside so they will not get scratched or broken.

INSTALL SEARS BYPASS VALVE AND / OR THE INLET OUTLET THREADED ADAPTORS

NOTE: If you will not install the bypass valve because you will have a three (3) valve bypass, skip steps 6 & 7, but do steps 5 and 8.

5. Visually check and remove any foreign materials from the valve inlet and outlet ports. See Fig. 9. Carefully remove the two large plastic clips (you will use them). Check to be sure the turbine and turbine support are firmly in place. See Fig. 10.

BYPASS VALVE:

6. Put a light coating of silicone grease on the o-ring seals and slide onto the bypass valve.

7. Push the 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. See Fig. 11.

CAUTION: Be sure the clips snap firmly into place so the bypass valve will not pull out. See Fig. 11.

INLET AND OUTLET THREADED ADAPTORS:

8. Put a light coating of silicone grease on the o-ring seals and slide into the threaded adaptors. Push the adaptors into the valve inlet and outlet ports, or bypass valve ports, as far as they will go. Both adaptors are the same and fit either port. Snap the two large holding clips

1. Cut pipe to correct length.

2. Solder (WHEN COOL, do Step 3).

3. Put threaded adaptor into bypass valve port.

4. Solder NOTE: To be certain heat will not travel down the pipe and into the bypass valve (or installation adaptors), wrap the bottom of the pipe and the bypass valve in a wet rag.

POSITION SOFTENER INTO PLACE

Complete the following steps to position the softener.

1. Grip under the ridge on the salt tank sidewall.

2. Carefully rock back and forth into position.

3. Move the softener into position.

4. Place on a level and smooth surface. If needed, put a piece of 3/4” plywood, at least 17'' x 20'', under the tank. Then put spacers under the plywood to level the softener. See Fig. 14.

NOTE: Do not put shims or spacers directly under the tank, without the plywood. The weight of the softener, when full of salt and water, may cause the tank to puncture or break at the shim or spacer.

CONNECT THE SOFTENER

Refer to your plan drawing. See Fig. 5. Measure, cut (thread if needed) and put all pipe and fittings together up to the main water pipe, or to the bypass valve(s) you installed in the previous step.

CAUTION: Never solder fittings while connected to nonmetallic parts. Wait until soldered pipe has cooled before connection. See Fig. 15.

CAUTION: Be careful when putting pipe fittings together. Do not cross thread, and do not overtighten.

Connect Valve and Salt Tank Drains

CONNECT THE VALVE DRAIN HOSE

Take a length of 3/8” inside diameter drain tubing and attach one end to the drain fitting. See Fig. 16. Use a tube clamp to hold it in place. Put the other end of the tubing over a floor drain, into a laundry tub, standpipe, or other suitable drain. Check your local codes.

Leave an air gap of about 1-1/ 2'' between the end of the hose and the drain. This gap is needed so you don’t get a backflow of sewer water into the softener. Do not put the end of the hose into the drain or connect without the air gap.

Place and support the hose so it does not kink or have sharp bends. Secure the hose end so water pressure does not cause the hose to “whip”. Tie or wire it in place. Do not pinch the hose shut. The softener will

not work if this drain hose is pinched, plugged, closed or restricted in any way. Direct drain flow

down into drain from drain line as flow could possibly over shoot the drain cover.

Keep the hose lower than the drain fitting. In some homes, to get to a drain you must raise the hose and run it overhead. If you need an overhead drain, do not raise the hose more than 8' above the floor. A copper drain tube is best to use.

COPPER DRAIN TUBE: The local plumbing codes may require the use a copper valve drain tube. A cop-

per tube is also best to use for an overhead drain. Use a copper drain tube if the softener is installed outside, or in the sunlight. Heat from the sun can soften, flatten and close up some kinds of tubes.

To adapt a copper drain tube to the softener, buy a compression fitting (1/4'' female pipe threads x 1/2'' O.D. tube) and tubing from your local hardware store.

CONNECT SALT TANK OVERFLOW TUBING

1. Locate the rubber grommet, tube adaptor and tube clamp (see Fig. 16) that are in the parts bag.

2. Push the grommet into the hole in the salt tank wall so half is inside and half is outside.

3. Push the bigger end of the tube adaptor into the grommet.

4. Push one end of a length of 3/ 8'' I.D. tubing onto the tube adaptor, using the tube clamp to hold it in place.

5. Put the other end of the tubing over the floor drain.

IMPORTANT: Overflow water must run downward through the tubing. Do not raise the tubing higher than the grommet and tube adaptor. See Fig. 16.

IMPORTANT: Do not connect to the valve drain hose you installed in step 1. Both drains must have a separate hose or tube.

NOTE: Overflow drain tubing is available from Sears. See parts list in back of manual.

Leak Test

LEAK TEST

To check for leaks, complete the following steps:

CAUTION: To avoid water or air pressure damage to softener 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. Fully open two cold, soft water faucets near the softener.

2. Look at the pictures in Fig. 18 and 19 to determine your kind of bypass valve(s). Place bypass valve(s) in “bypass” position. On a single valve, slide the stem inward to bypass. On a three (3) valve system, close the inlet and outlet valves and open the bypass valve.

3. Fully open the house main water pipe shutoff valve. Observe steady water flow from both open faucets.

4. Place bypass valve(s) in SERVICE EXACTLY as follows: Keep soft water faucets open. a. Single Bypass Valve: Slowly, slide pull the valve stem outward toward service, pausing several times to allow the softener to pressurize slowly. b. Three Valve Bypass: Fully close the bypass valve and open the outlet valve. Slowly, open the inlet valve, pausing several times to allow the softener to pressurize slowly.

5. After about three minutes, open a hot water

faucet for about one minute, or until all air is expelled, then close.

6. Close both cold water faucets.

7. Check your plumbing work for leaks and fix right away if any are found. Be sure to observe previ-

ous caution notes.

NOTE: If this procedure is performed on a new softener, water coming from the taps may initially be discolored. This normally occurs the first time water runs through the resin bed. The discolored water is not harmful, and the discoloration will not last more than a few minutes.

Electrical Requirements

INSTALL GROUNDING CLAMP BETWEEN THE SOFTENER IN AND OUT PIPES

The house cold water pipe (iron or copper) is often used to ground all electrical outlets in the home. Outlets are grounded to protect you from shock when you touch any electric appliance plugged into the outlet. If you installed the single bypass valve, the cold water pipe ground is broken. See Fig. 20 and 21.

IMPORTANT: Be sure the cold water pipe has direct metal to metal contact all the way to the ground. Plastic, rubber or other electrically insulating parts such as hoses, fittings, washers or gaskets can break the direct metal to metal contact. Also check the water meter (city water) or the well pump. Install #4 copper jumper wires, clamped tightly on both ends, across insulated parts. See Fig. 21.

To restore the ground, take the ground clamp kit that is in the parts bag. Install across the inlet and outlet copper tubes. See Fig. 20. Be sure good contact is made between the pipe and the clamps.

ELECTRICAL POWER OUTLET FOR YOUR SOFTENER

The softener works on 24 volt, 60 Hz electric power. The included transformer changes standard 120 volt AC house power to 24 volts. You must plug the transformer into a grounded, 120 volt outlet only. Be sure the outlet is always “live” so someone cannot turn it off by mistake. See Fig. 22.

Note: The included transformer is made for inside use only. Be sure the electrical outlet you plug the transformer into is inside, to protect from weather.

If the words PRESENT TIME do not show in the display, press the SELECT button until they do show in the display. Press the UP or DOWN buttons to set the present time. Press UP to move the display ahead; press DOWN to move the time backward. If the present time is between noon and midnight, be sure PM shows. If the present time is between midnight and noon, be sure AM shows. Each press of the UP or DOWN buttons changes the time by one (1) minute. Holding the buttons in changes the time rapidly.

SET WATER HARDNESS NUMBER

To set the water hardness number, complete the following steps:

1. Press the SELECT button once to display 25 (flashing) and HARDNESS. The grains per gallon (gpg) hardness of your water supply is on your water analysis report. Be sure to enter water test results on the Facts & Figure Chart on page 3.

2. If your water supply contains iron, compensate 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 I ppm of iron. In this example, you would use 30 for your hardness number.

2 ppm iron x 5 = 10 20 gpg hardness +10 30 HARDNESS NUMBER

3. Press the UP or DOWN buttons to set your water hardness number in the display. The DOWN button moves the display to 1. The UP button moves the display to the highest setting (see maximum setting for your model in the specifications).

Sanitize The Water Softener

SANITIZE THE WATER SOFTENER

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, or cause bacteria to form or grow. However, during shipping, storage, installing and operating, bacteria could get into the softener.

SANITIZE YOUR WATER SOFTENER AS FOLLOWS:

1. Be certain the bypass valve is pulled out to

“service” position.

2. Lift the salt hole cover and use a pail add up to 3 gallons

of water to the salt storage tank.

3. Remove the brine well cover (Fig. 30) and pour about 3/4

ounce, or 1 to 2 tablespoons, of common 5.25%

, unscent- ed, household bleach (Clorox, Linco, BoPeep, White Sail, Eagle, etc.) in the softener brinewell. Replace the brinewell cover.

4. Press the REGENERATION 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 26) for service and flushes residual chlorine from the softener.

NOTE: This recharge takes about 2-1/2 to 2-3/4 hours, depending on the salt type setting.

NOTE: During a recharge the water softener bypasses raw water to the home. You will not get salty water or affect the regeneration cycle if water is used at this time.

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.

Your new Sears softener is now softening the water for your household needs. However, your WATER HEATER is filled with hard water. To have fully soft water right away, you can drain the water heater so it refills with soft water. If you don’t drain the water heater, it will take a few days before you have fully soft water.

To drain the water heater, open a hot water faucet and let it run until the water runs cold. Then close the faucet.

Adding Salt To The Storage Tank

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 water softener is very efficient, it is not necessary to keep it full. Especially in humid areas, it is best to fill the storage tank one quarter to one half full, and to add salt more often. Salt bridging 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.To maintain optimum performance of your water softener, the salt tank should be cleaned out every 2 to 3 years.

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 required for proper operation.

NOTE: The salt monitor system 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 (KCI) as a regenerant, following these suggestions will help give you years of maintenance free service.

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

2. A softener using KCI should not be placed in areas with temperature fluctuations and high humidity (KCI 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.

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 sodium. That is equivalent to eating 2-1/2 slices of white bread.

WATER SOFTENING SALT WITH IRON REMOVING

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 (refer to the Parts List in back of manual for part number) for periodic treatments to keep your resin bed clean. This is available at your local Sears store.

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 contaminants.

EXTRA RECHARGE

Sometimes, a manually started regeneration (recharge) may be desired, 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. Add salt to the softener before regenerating.

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).

RECHARGE NOW

Press the REGENERATION button and hold until *RECHARGE screen shows in the display and the green recharge LED is flashing. This screen shows the regeneration time and cycle time remaining. After regneration, 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.

RECHARGE TONIGHT

Press and release (do not hold) the REGENERATION button. RECHARGE TONIGHT flashes in the display, the green recharge LED is on and the softener begins regeneration at the next preset recharge time. Press and release the REGENERATION button once more if you decide to cancel the regeneration, RECHARGE TONIGHT will no longer be displayed on the screen and the green recharge LED will turn off.

ype allows you to chose between sodium chloride (NaCl), which is regular softener salt, or potassium chloride (KCl), which is an alternative to sodium chloride. KCl should be used in accordance to the following steps to 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

high temperature changes or high humidity (KCl will harden in these environments and may make the softener inoperable).

3. Check the brine tank and brinewell (black tube in salt stor-

age tank) monthly. If hardening is present, pour small amounts of warm water on hardened areas until they loosen.

4. Be sure to set the correct salt type depending on which

salt type is used (NaCl or KCl). Use the UP or DOWN arrows to toggle between NaCl or KCl and press SELECT to enter information and return to Salt Options screen.

NOTE: If KCl is selected the normal operating screen will display KCl in the lower right hand corner of the display.

Salt Ef

ficiency has three options.

High Performance

, Salt Ef

KENMORE’S ULTRA CLEANSING FEATURE

The ultra cleansing feature keeps larger particles of sediment from entering the home’s plumbing system. As water passes through the softener, the larger sediment particles are collected in the integrated basket and then rinsed to the drain before each regeneration. The ultra cleansing feature provides added protection for water using appliances by reducing the chance of larger particles entering the various products valves and screens. An extra backwash will be preprogrammed into the electronics by the factory. This extra backwash will help keep the ultra cleansing feature screen clean.

Important: The ultra cleansing feature is not intended to replace pretreatment filtration. For problem water applications, additional sediment filtration is recommended.

Sears offers a full line of dedicated sediment filtration products.

How Your Water Softener Works

FIG. 52

SOFT WATER SERVICE AND 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. 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 cleaning with salt brine is needed. This cleaning is called regeneration or recharge. Regeneration is started at 2:00 a.m. by the electronic timer. It takes place in 5 stages or cycles.

These are: 1. Fill

2. Brining

3. Brine Rinse

4. Backwash

5. Fast Rinse

NOTE: If the Clean Feature is set to “On”, additional backwash and fast rinse cycles occur before the fill cycle.

REGENERATION

The five steps listed above are described in detail over the next several pages.

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. 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.

How Your Water Softener Works

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 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 water used between regenerations.

• The amount of resin in the softener,

• How fast the brine goes through the bed.

The nozzle and venturi makes 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 minerals 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.

BACKWASH: During backwash, water flows UP through the resin tank at a fast rate to flush iron minerals, dirt and sediments from the bed and to the drain. The bed lifts and expands for good cleaning.

How Your Water Softener Works

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.

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.

SOFT WATER SERVICE AND REGENERATION

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 hard water. The softener, as factory programmed, regenerates from 2:00 AM to about 4:20 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. 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.

ELECTRONICS

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, 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

(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. When the regeneration begins, *RECHARGE or RECHARGE TIME REMAIN- ING flashes during the regeneration.

* 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.

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.

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. 56. 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.

KEEPING THE WATER SOFTENER CLEAN

NOZZLE & VENTURI

A clean nozzle and venturi (see Fig. 57) 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 clean the nozzle and venturi, complete the following steps:

1. Remove the softener top cover. Be sure the softener

is in service cycle (no water pressure at nozzle and venturi).

2. Turn off the cap from the nozzle and venturi housing.

3. Lift out the screen support and screen. Do not lose

the large o-ring seal.

4. Remove 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.

5. Carefully replace all parts in the correct order.

6. Lubricate the o-ring seal with silicone grease or

Vaseline and place in position.

7. Install and tighten the cap, by hand only. Do not

overtighten, which may break the cap or housing.

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 section in this manual. 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 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 for this. See Parts List in back of manual for part numbers. Clean the bed at least every six (6) months. If iron shows up in the soft water before six (6) months, clean more often. Printed instructions are on the resin bed cleaner bottle.

Care Of Your Water Softener

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:

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 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.

4. Unplug the transformer at the wall outlet. Remove

the salt hole cover and the main cover. Take off both drain hoses.

5. Carefully remove the large holding clips at the soften-

er inlet and outlet. Separate the softener from the plastic installation adaptors, or from the bypass valve.

6. Remove the brinewell cover and disconnect the brine

valve tubing at the nozzle and venturi assembly. Lift the brine valve out of the brinewell. Tip the brine valve upside down to drain water.

7. 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.

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 rags to keep dirt, bugs, etc. out.

CHECKLIST TO HELP YOU SAVE MONEY

If your water softener fails to work, make the following easy checks. Often, you will find what is 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.

1. Also read ERROR CODE.

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 code appears. It must show H46 for Model 38426 or H47 for model

39426. 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 the correct code, press either the UP 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.

Keep this manual with your water softener. If repairs are needed, the service technician must have the information on the following pages.

ALWAYS MAKE THESE INITIAL CHECKS FIRST

1. Does the time display show the correct time of

day?

• If display is blank, check power source to the sof-

tener.

• If time is flashing, power was off for over 48 hours. The softener resumes normal operation but regenerations occur at the wrong time.

• If an error code (Example: Err3) shows in the faceplate display, go to AUTOMATIC ELECTRONIC DIAGNOSTICS.

2. Plumbing bypass valve(s) must be fully in service position.

3. The inlet and outlet pipes must connect to the softener inlet and outlet respectively.

4. Is the transformer plugged into a “live”, grounded wall outlet, and the power cable fastened securely to the controller?

5. The valve drain hose must be free of kinks and sharp bends, and not elevated over 8 ft. above the floor.

6. Is there salt in the storage tank?

7. Is the brine tubing connected? Brine tubing connects to nozzle venturi and brine valve assembly.

8. Is the brine valve float set right?

9. Press the SELECT button two times to display the hardness setting.

Be sure it is the correct setting for the household’s water supply. (Make a hardness test of the raw water and compare with the hardness setting. Also test a soft water sample to verify if a problem exists.) Press the SELECT button twice more to return to present time in the display.

If you do not find the problem after making initial checks, do the MANUAL INITIATED ELECTRONIC DIAGNOSTICS, and the MANUAL ADVANCE REGENERATION CHECK.

The faceplate timer (PWA) computer has a self-diagnostic function for the electrical system, except for input power and water meter. The computer monitors electronic components and circuits for correct operation. If a malfunction occurs, an error code appears in the faceplate display.

The chart below shows the error codes that could appear, and the possible defects for each code.

While an error code appears in the display, all face plate buttons are inoperable except the SELECT button. SELECT remains operational so the service person can make the MANUAL INITIATED ELECTRONIC DIAGNOSTICS (below) to further isolate the defect, and check the water meter.

PROCEDURE FOR REMOVING ERROR CODE FROM FACEPLATE:

• Unplug transformer from outlet.

• Correct defect

• Plug in transformer.

• Wait for 8 minutes.

The error code will return if the defect was not corrected.

MANUAL INITIATED ELECTRONICS DIAGNOSTICS:

1. To enter diagnostics, press the SELECT button once to go to the Main Menu. Move the black bar to Service Mode and press Select. Move black bar to Diagnostics and press Select.

You will see the display, showing valve cycle position, position switch status (open or closed), and turbine operation.

TURBINE OPERATION: If no water is flowing through the softener, the turbine indicator displays 3 zeros. When water is flowing, a 000 to 140 count repeats for each gallon 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 reading in the display, with faucet open, pull the sensor from the valve outlet port. Pass a small magnet back and forth in front of the sensor. You should get a reading in the display. If you get a reading, unhook the in and out plumbing and check the turbine for binding.

POSITION SWITCH STATUS: With the valve in service, or any of the recharge cycles, the switch indicator will show open, while the valve is rotating from one position to another, the indicator will show the switch closed. A defect is probable if indications vary from this pattern.

NOTE: If the faceplate is left in a diagnostic display (or a flashing display when setting times or hardness), present time automatically returns if a button is not pressed within 4 minutes. To return to the diagnostic display, repeat step 1.

2. Press the RECHARGE button to advance the valve to each position and observe the switch and position indicators to verify component operation, or to possibly isolate a defect.

3. Press Select once to move back to the Service Mode screen. Move black bar to Set Model and press Select. Verify the model code.

This code identifies the softener nominal capacity size. If the wrong number shows, the softener will operate on incorrect programming. Do the following as needed.

HF46 or HF47 does show - Press the SELECT button until the normal operating display shows.

To change HF number - Press the UP or DOWN button until either HF46 for Model 38426, or HF47 for Model 39426, shows in the display. Then, press the SELECT button and reset the timer.

TIMER PWA REPLACEMENT

Be sure the valve is in service position when replacing the timer PWA (observe valve cycle indicator). If

after installing and programming the replacement timer PWA, the valve is not in service position, do the following to assure correct cycle orientation, or timing, between the faceplate and valve.

Use the MANUAL ADVANCE procedures with the RECHARGE NOW button, advance through the recharge cycles until the valve stops in service position, and RECHARGE no longer flashes in the display.

NOTE: The valve motor may automatically drive through several valve positions while searching for service. If an error code occurs, unplug the transformer, then plug in again.

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, and the manual initiated diagnostics.

NOTE: The faceplate 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 REGENERATION button and hold in for 3 seconds. *RECHARGE and Fill begin to flash (or clean backwash begins, if set) as the softener enters the fill cycle of regeneration.

* NOTE: If the CLEAN feature is set to ON, a clean-

ing backwash (CLEAN and Bkwsh or Rinse flashes in the display, along with the minutes of the clean cycle remaining), precedes the recharge.

2. When FILL is on steady, remove the brinewell cover and, using a flashlight, observe fill water entering the tank.

3. If water does not enter the tank, look for an obstructed nozzle, venturi, fill flow plug, brine tubing, or brine valve riser pipe.

CYCLE FLOW RATES (GALLONS PER MIN.)

FILL (flow to salt storage tank) 0.3 (1.1 liters)

BRINING (flow to drain) .22 (.83 liters)

BRINE RINSE (flow to drain) .15 (.57 liters)

MAX. BACKWASH (flow to drain) 2.0 (7.6 liters)

MAX. FAST RINSE (flow to drain) 2.0 (7.6 liters)

4. After observing fill, press the REGENERATION button to move the softener into brining. A slow flow of water to the drain will begin. Verify brine draw from the brine tank by shining a flashlight into the brinewell and observing a noticeable drop in the liquid level.

NOTE: Be sure a salt bridge is not preventing water

with salt contact.

5. If the softener does not draw brine:

• nozzle and/or venturi dirty or defective.

• nozzle and venturi not seated properly on gasket

• restricted drain (check drain fitting and hose)

• defective nozzle and venturi seal

• other inner valve defect (rotor seal, rotor & disc,

wave washer, etc.)

NOTE: If water system pressure is low, an elevated drain hose may cause back pressure, stopping brine draw.

6. Again press REGENERATION 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 distributor, backwash flow plu or drain hose.

8. Press REGENERATION 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 REGENERATION once more.

ROTARY VALVE SERVICE

IMPORTANT: Before working on the valve, turn off the water supply and disconnect from electrical power.

TO RELIEVE PRESSURE:

• 3 VALVE BYPASS: Close the inlet valve and open a

soft water faucet. Then close the outlet valve and open the bypass valve.

• SEARS SPECIAL BYPASS: Slide the bypass valve stem to bypass position. Loosen three hex head screws toward the back side of the valve to allow pressure water to bleed out. Catch water with a rag.

DISASSEMBLY

To remove a part or group of parts, refer to the valve drawing. A common screwdriver or nut driver, Phillips screwdriver and pliers are the only tools needed to completely disassemble.

SERVICING THE VALVE

Inspect all o-rings, seals and gaskets for wear or defects.

Inspect the bottom surface of the rotor for scratches, chips or wear.

Note: If replacement is needed, be sure to use the current replacement part.

ASSEMBLY

Be sure all parts are in place and in the proper position. Lubricate ALL o-rings and seals with FDA approved silicone grease. To install the rotor seal, first place the seal into the valve groove, rounded side down (see cross-section). Apply a light coating of silicone grease to the seal’s crossing ribs. Then, carefully center the wear strip on the seal, and push it downward onto the seal.

Install the nozzle and venturi seal and drain seal. Assemble wave washer bearing, the wave washer, and two o-rings, onto the rotor top shaft. Then center the rotor in the valve body, on the rotor seal.

Lower the cover onto the valve body and rotor shaft. Then install the cover holding screws. Before tightening the screws, install the valve cam and gear.

Then, turn the rotor (clockwise only) to service position. Tighten the screws using a criss-cross pattern. If a torque wrench is available, torque to 30-40 inch pounds. Do not over tighten.

Lubricate the gear on the motor, and the valve cam gear with Molykote grease, or other high quality gear lubricant.

Be sure to orient switch as shown, with lever toward the cam.

Service Tech Information

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 SOFT water fin through the venturi. Fill flow continues to the brine valve, and into the salt storage tank. Soft water is still available to the house lines.in.

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 closes to end brine draw, water flow continues in the same directions to slowly RINSE brine from the resin bed and to the drain.

FAST RINSE CYCLE

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.
