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.

Be sure to plan “IN” and “OUT” piping so water flow is to the softener valve inlet. Plan a crossover if flow is from left to right.

DRAW IN YOUR PIPES AND FITTINGS

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

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.

Complete the following steps to assemble the adaptors or bypass valve.

1. Close the shutoff valve on the house main water pipe, near the water meter or pressure tank, to turn off the water. See Fig. 7.

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

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.

PLUG IN THE TRANSFORMER

Plug the transformer into the electrical outlet.
