A safety GUIDES

▲ Read all steps, guides and rules carefully before installing and using your new water softener. 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.

Your water softener will remove hardness minerals and “clear water” iron* from water, up to the iimits 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.

K' Be sure to restart the water heater. See page 3-9.

California Efficiency Requirement

Your Kenmore Water Softener has a "Eiigh 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.

SECTION 1 I WATER SOFTENER START UP

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® 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.

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

salt storage tank with up to 3 gallons of water.

Remove the brinewell cover (FIG. 3) and pour about 3/4 ounce, or 1 to 2 tablespoons, of com mon 5.25%, imscented, household bleach (Clorox, Linco, BoPeep, White Sail, Eagle, etc.) in the

softener brinewell. Replace the brinewell cover. Press the RECHARGE button and hold for 3 se

conds to start a recharge. This first recharge does

several things.

FIG. 3

• 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 2-1 /2 or 2- 3/4 hours, de pending on the salt type setting (page 1-4).

You can sanitize the softener ivith 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 I WATER SOFTENER START UP

E. ADDING SALT TO

Brine (salt dissolved in water) is needed for each and every regeneration. The water for making brine is me tered 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. Especially 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) oc curs 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 required for proper operation (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 (KCl) as a regener

ant, following these suggestions will 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 temperature fluctuations and high humidity (KCl 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 KCl salt setting you must increase your hardness setting by 25% to ensure continuous soft water as in example below.

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 con tent. It is recommended to use Sears Resin Bed Clean er 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 so dium 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.

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 so dium and other drinking water contaminants.

If electrical power to the softener goes off, the time display is blank but the face plate timer keeps the correct time for about 6 hours. When electrical pow er comes on again, you have to reset the present time only if the display is flashing. The HARDNESS and RECHARGE TIME never require resetting un less a change is desired.Even if the timer is incorrect after a long power outage, the softener works as it should to keep your water soft. However, regenera tions may occur at the wrong time of day until you reset the timer to the correct time of day (page 1-3).

^ KENMORE'S ULTRA CLEANSING FEATURE (UltraSoft 280 only)

The ultra cleansing feature keeps larger particles of sediment from entering the home's plumbing sys tem. As water passes through the softener, the larg er sediment particles are collected in the integrated basket and then rinsed to the drain before each re generation. The ultra cleansing feature provides added protection for water-using appliances by re ducing the chance of larger particles entering the various product's valves and screens.

An extra backwash will be pre- programmed into the electronics by the factory (see "Clean Feature" in Section 2 "Faceplate Timer Features" in this manu al). This extra backwash will help keep the ultra cleansing feature screen clean.

Important: The ultra cleansing feature is not in tended to replace pretreatment filtration. For prob lem water applications, additional sediment filtra tion is recommended.

Sears offers a full- line of dedicated sediment filtra tion products including the Whole Home Filter and Automatic Clarifying Filter.

SECTION 2 HOW YOUR WATER SOFTENER WORKS

B. SOFT WATER SERVICE and REGENERATION

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 at tracts 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 miner als they can, and cleaning with salt brine is needed. This cleaning is called regeneration or recharge. Re generation 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:

D FILL B BACKWASH B BRINING B BRINE RINSE

FAST RINSE

REGENERATIONSERVICE

n 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 as shown in FIG. 6. 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.

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 dean the resin depends on:

- - the amount of service water used between regen erations,

- - the amount of resin in the softener,

- -how fast the brine goes through the bed. The nozzle and venturi (FIG. 7) 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 miner als 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.

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 (FIG. 9).

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.

SECTION 2 HOW YOUR WATER SOFTENER WORKS

B. SOFT WATER SERVICE and REGENERATION

AUTOMATIC BYPASS

During the brining, brine rinse and backwash cycles of regeneration, HARD water goes through the soft ener valve and to the house pipes. If a faucet is opened, hard water is there for your needs. Howev er, you should not use hot water, if possible, because the water heater will refill with hard water. The soft ener, 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 re charge time to 12:00 AM or 1:00 AM (page 1-4). Then regeneration will start and end that much ear lier 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 [î] a WATER METER, and [2] a COMPUTER.

[T] WATER METER—The water meter is in the soft ener valve outlet. As water flows through the meter, it sends electric pulses to the computer. The com puter changes the pulses to a measure in gallons of water.

[2] COMPUTER — The computer is part of the face

plate timer circuit board. It is programmed to know the softener's capacity (how many grains of hard ness minerals it will take out of the water before a re generation 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 pattern best for your needs, the computer uses: (1) water usage from the meter, (2) hardness setting, (3) softener capacity, and (4) time since the last regeneration. The computer al ways adjusts this pattern to your water using hab its. 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 re moved. 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, KELHARGE or RE CHARGE TIME REMAINING flashes during the re generation.

^ 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.

WHEN TO ADD SALT: The Salt Monitor System (see page 2-1) will turn the low salt light warn you when to refill with salt. Check for a low salt light a few weeks after you install the soften er, and every week after that. Add salt at about the #2 salt monitor level. At this level, the tank is

on to

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 Sys tem, page 2-1.

Note: You will have a loss in softening capacity and may get partly hard water if less than 10 inches (salt mon itor level 2) of salt is in the storage tank.

PLEASE SEE PAGE 1-6 FOR SALT FILLING DIRECTIONS.

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

SALT BRIDGE

Sometimes, a hard crust or salt bridge forms in the salt storage tank. It is usually caused by high hu midity 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 wa ter 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. 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.

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 re generation. 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 cover. 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 hous

ing.

2) Lift out the screen support and screen, do not lose

the large o-ring seal.

3) Then the nozzle and venturi. Wash and rinse the parts in warm water until clean. If needed, use a small brush to remove iron or dirt. Also check and clean the gasket, flow plugs and screens.

Carefully replace all parts in the correct order. Lu bricate the o-ring seal with silicone grease or Vase line and place in position. 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 (cal cium and magnesium) out of the water. It can also control some "clear water" iron. See maximum al lowed 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 waterbe gins 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 fil ter 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

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:

Close the shut-off valve on the house main wa

ter pipe, near the water meter or pressure tank.

Open a faucet in the soft water pipes to vent

pressure in the softener.

Q 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. Re move 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.

FIG. 12

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.

allow the softener's weight to rest on the inlet and outlet fittings or they will break.

Drain All Water From Softener

Do not

Remove the brinewell cover and disconnect the brine valve tubing at the nozzle and venturi as

sembly (see page 3-2). Lift the brine valve out of the brinewell. Tip the brine valve upside down to drain water.

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.

Be sure all parts are in place and in the proper posi tion. Lubricate ALL o-rings and seals with FDA ap proved 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, care fully 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 tight ening the screws, install the valve cam and gear.

SECTION 5

SERVICE TECH. INFORMATION

C. WATER FLOW THROUGH THE SOFTENER VALVE

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 fill 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.

SERVICE TECH. INFORMATION

C. WATER FLOW THROUGH THE SOFTENER VALVE

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.

BACKWASH CYCLE

Timer/switch action again allows the motor to turn the rotor & disc to place the valve in BACKWASH, stopping water flow to the nozzle. Water is routed down and out the bottom distributor, up through the bed, and out the top distributor to the drain. The fast flow (controlled by a flow plug in the drain fitting) flushes dirt, sediments, iron deposits, remaining brine and hardness to the drain.

SERVICE TECH. INFORMATION

C. WATER FLOW THROUGH THE 30FTENER VALVE

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.
