Installation [_ Instructions CONNECT AND RUN THE VALVE DRAIN HOSE ICONT.i _f] • Route the brine tubing out of the largest hole in the brine tank sidewall. Use the compression nut (in parts bag) to connect tubing to the nozzle assemblg at the main valve. • Elevating the drain hose mag cause back pressure that could reduce the brine draw during recharge. If raising the drain line overhead is required to get to the drain point, measure the inlet water pressure to the softener first.
Installation 19] INSTALL GROUNDING CLAMP Instructions I_ -ADANGER: Failure to properly attach ground clamp could result in electrical shock. If plumbing is metal, to maintain electrical ground continuity in the house cold water piping, install the included ground clamp as shown. • Clean pipe with emery paper in the area where the clamp is to be installed. Install grounding clumps us shown, making sure clamps fit freely around pipe. Make sure lock washer is in place. Hundtighten screwdriver.

About the water softener system, ge.com Service When the water softening system is providing soft water, it is called "Service." During service, hard water flows from the house main water pipe into the water softening system. Inside the water softening system 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 hard minerals. This is called ion-exchanging. It is much like a magnet attracting and holding metals.
About the water softener system. Breaking a Salt Bridge Sometimes, a hard crust or salt bridge forms in the salt storage area. It is usuallu caused bu high humiditu or the wrong kind of salt. When the salt bridges, an empt Uspace forms between the water and salt. Then salt will not dissolve in the water to make brine. If the brine tank is full of salt, it is hard to tell if Uou have a salt bridge. Salt is loose on top, but the bridge is under it. The following is the best wau to check for a salt bridge.
