SECTION 1 1A. WATER SOFTENER START-UP 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 limits shown on page 18.
SECTION 1 1B. WATER SOFTENER START-UP CHECK LIST OF ALL STEP-BY-STEP GUIDES TO INSTALL Refer to the Installation Manual, part no. 7141417, for stepĆbyĆstep guides. To be sure you have done all the steps to install the softener, read the following list. Page numbers referred to are in the ✔ Is the house water flow going INTO the softenĆ er valve INLET? Trace piping to be sure. See pages 10 and 11. ✔ Is the plumbing bypass valve (or 3 valves) set for SERVICE? See page 18.
SECTION 1 1C. WATER SOFTENER START-UP PROGRAM THE TIMER FIG. 1 When the transformer is plugged in, the model code SC21 shows in the face plate display for a few seconds, followed by a test number (example: S4.0). After the test number, 12:00 AM begins to flash. PRESENT TIME and RECHARGE TONIGHT show at the bottom of the display. repeatedly when the display reaches 1 using the DOWN button, or the highest hardness setting using the UP button. 1.
SECTION 1 1C. WATER SOFTENER START-UP PROGRAM THE TIMER At the 2:00 AM RECHARGE TIME setting, the softener begins reĆ generation (see pages 11 and 12) at 2:00 AM, ending no later than 4:00 AM. This is a good time in most households because water is not being used (see AUTOMATIC BYPASS, page 13). If a different RECHARGE TIME setting would be better for your household, do the following. 2. SET WATER HARDNESS NUMBER: ■ Press the SELECT button once to display 15 (flashing) and HARDNESS.
SECTION 1 1D. WATER SOFTENER START-UP SANITIZING 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, 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 suggested① when installing. FIG. 2 ADD WATER Brinewell Cover (remove and add about 3/4 oz.
SECTION 1 1E. WATER SOFTENER START-UP FILL THE STORAGE TANK WITH SALT 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. However, you must keep the tank filled with salt. FIG. 3 ADD SALT Fill the tank with NUGGET or PELLET water softener salt. DO NOT use rock salts, as they have dirt and sediments that will stop the softener from working.
SECTION 2 2A. HOW YOUR WATER SOFTENER WORKS FACE PLATE TIMER FEATURES EXTRA RECHARGE Sometimes, a manually started regeneration (reĆ charge) may be desired, or needed. Two examĆ ples are: PROGRAM MEMORY 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 power comes on again, you have to reset the present time if the display is flashing.
SECTION 2 2A. HOW YOUR WATER SOFTENER WORKS 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 (FIG. 4). As hard water passes through the bed, each bead attracts and holds the hardness minerals. This is called ionĆexchanging.
SECTION 2 2B. 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: FIG. 7 WATER FLOW THROUGH THE SOFTENER IN BACKWASH -- the amount of resin in the softener, -- how fast the brine goes through the bed. The nozzle and venturi (FIG.
SECTION 2 2B. HOW YOUR WATER SOFTENER WORKS SOFT WATER SERVICE AND REGENERATION COMPUTER Ċ The computer is part of the 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 on page 7, you set it for the grains per gallon (gpg) hardness of the water.
SECTION 3 3A. CARE OF YOUR SOFTENER SALT…REFILLING STORAGE TANK/BREAKING A SALT BRIDGE WHEN TO REFILL WITH SALT: Check the salt level a few weeks after you install the softener and every week after that. Refill when the storage tank is about 1/3 full. Never let the softener use all the salt before refilling. Without salt, you will soon have hard water. IMPORTANT: You will have a loss in softening capacity and may get partly hard water if less than 10 inches of salt is in the storage tank.
SECTION 3 3D. CARE OF YOUR SOFTENER KEEPING THE WATER SOFTENER CLEAN COVERS To keep your new Sears water softener looking nice, apply a coat of paste wax and repeat once a year. When dusty, wipe it with a damp cloth to keep it sparkling. NOTE: Never use cleaners having ammonia or abrasives. They may scratch and dull the surface. NOZZLE AND VENTURI A clean nozzle and venturi (FIG. 10) is a must for the softener to work right.
SECTION 3 3D. CARE OF YOUR SOFTENER KEEP THE 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: FIG. 11 DRAIN WATER FROM THE SOFTENER Close the shutĆoff valve on the house main water pipe, near the water meter or pressure tank. Open a faucet in the soft water pipes to vent pressure in the softener.
SECTION 3 3D. CARE OF YOUR SOFTENER HELPFUL HINTS CHECKLIST ... TO HELP YOU SAVE MONEY If your water softener fails to work, make the following easy checks. Often, you will find what's wrong yourself and you won't have to call and wait for service. If, after making the checks, your softener still does not work right, call your Sears Service Department, or call toll free, number 1-800-426-9345 for telephone assistance. NOTE: Also read ERROR CODE, page 10.

SECTION 5 5A. SERVICE TECH. INFORMATION TROUBLESHOOTING NOTE: If water system pressure is low, an elevated drain hose may cause back pressure, stopping brine draw. 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. 3. Again press ON/OFFĆHOLD to move the softener into backwash.
SECTION 5 5B. SERVICE TECH. INFORMATION ROTARY VALVE SERVICE BEFORE WORKING ON THE VALVE, TURN OFF THE WATER SUPPLY AND DISCONNECT FROM ELECTRICAL POWER. TO RELIEVE PRESSURE: 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.

SECTION 5 SERVICE TECH. INFORMATION 5C. 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.
