The computer changes the pulses to a measure in gallons of water. 13 SECTION 3 3A. CARE OF YOUR SOFTENER SALT. . . REFILLING STORAGE TANK/BREAKING A SALT BRIDGE 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. WHEN TO REFILL WITH SALT: Check the salt level a few weeks after you install the softener and every week after that. Without salt, you will soon have hard water. PLEASE SEE PAGE 9 FOR SALT FILLING DIRECTIONS. SALT BRIDGE Sometimes, a hard crust or salt bridge forms in the salt storage tank. When the salt bridges, an empty space forms between the water and salt. 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. Hold a broom handle, or like tool, up to the softener as shown in FIG. Make a pencil mark on the handle, 1 or 2 below the top height of the rim. If a hard object is felt before the pencil mark gets to the top of the tank, it's most likely a salt bridge. DO NOT TRY TO BREAK THE SALT BRIDGE BY POUNDING ON THE OUTSIDE OF THE SALT TANK. Tip the bottom of the softener up a few inches and hold until all water has drained. out. 16 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. If an error code is not dispIayed, press and hold the SELECT button until (example:000 ) shows in the display. If any other SC number shows, the softener computer is working on incorrect input and would probably be the cause of the problem. Then, press select to return a flashing 12:00 AM display, and reset the timer, page 6. PROBLEM CAUSE CORRECTION See IMPORTANT note, pages 4 and 7. Use the RECHARGE NOW feature to start an immediate recharge, and open soft water faucets to purge salt taste. Restore power, reset timer if needed, and open soft water faucets to purge salt taste. With the power back on, look at the time display and read PROGRAM MEMORY, page 10. [. . . ] 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. 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 (and ``CLEAN'') 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. 25 SECTION 5 SERVICE TECH. [. . . ]
