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. 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. Make a pencil mark on the handle, 1 or 2 below the top height of the rim. 10 CLEANING THE NOZZLE & VENTURI Cap O­ring Seal Screen Support *Flow Plug (DUDC or DDUC) Screen Nozzle & Venturi Gasket IMPORTANT: Be sure small holes in the gasket are centered directly over the small holes in the nozzle & venturi housing.

IRON FROM THE RESIN BED Your water softener takes hardness minerals (cal cium and magnesium) out of the water. Also, it can control some clear water" iron. See maximum allowed in the specifications on page 19. With clear water iron, water from a faucet is clear when first put into a glass. After 15 to 30 minutes, the water begins 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 filter 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. If iron shows up in the soft water before 6 months, clean more often. [. . . ] The fast flow (controlled by a flow plug in the drain fitting) flushes dirt, sediments, iron deposits, remaining brine and hardness to the drain. 26 SECTION 5 SERVICE TECH INFORMATION 5C. WATER FLOW THROUGH THE SOFTENER VALVE FAST RINSE CYCLE soft water to valve outlet drain 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. [. . . ]
