Otherwise, run to a dry well. FIG.
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? OUT IN 1" NPT sweat adaptor (2)* Useteflontape, pipe or both.
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: 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. Check Water's Chemical Analysis: Sears sells a complete line of water treating equipment to correct various water problems.

SANiTiZETHE WATER SOFTENER Salt Hole 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.
ADDINGSALTTO THE STORAGETANK Brine(saltdissolvedin water)is neededforeachand 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.
CHECKLiST OF STEP-BY-STEP GUIDES TO iNSTALL Water Supply Review the following list to ensure you have completed all the installation procedures, 1. Check the incoming water, Has incoming water been tested? \ Valve Inlet Bypass Valve(s) 2. Remove cardboard packaging from salt tank, Single Bypass Valve 3. Is the incoming water going to the valve inlet? 4. Is the bypass valve placed into the service position? 5. Is the ground clamp installed? 6.
EXTRARECHARGE Sometimes, a manuallystartedregeneration (recharge) maybedesired,or needed.Twoexamples are: --_- - I'ULq RECHARGE PM NOW • 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.

SOFT WATER SERVICE AND REGENERATION WATER FLOW THROUGH THE SOFTENER IN SERVICE 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.
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.
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. WATER FLOW THROUGH THE SOFTENER IN FAST RINSE 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.
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. SALT BRIDGE Push tool into salt bridge to break 1" If the storage tank is full of salt, it is hard to tell if you have a salt bridge.
KEEPING THE WATER SOFTENER CLEAN CLeaning NozzLe & Venturi NOZZLE & VENTURI A clean nozzle and venturi (see Fig. 55) 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.
PROTECT FREEZING THE WATER SOFTENER FROM DRAIN ALL WATER FROM SOFTENER 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 pressure in the softener. Floor Drain 3. Move the stem in a single bypass valve to bypass.
CHECKLISTTO 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 SELECT1 button until the display changes.

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.
WATER FLOW THROUGH THE SOFTENER VALVE SERVICE SERVICE CYCLE 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.
WATER FLOW THROUGH THE SOFTENER VALVE BACKWASH BACKWASH CYCLE CYCLE Plug 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.
