13COMPLETE INLET AND OUTLET PLUMBINGWARNING A copper orgalvanized coldwater pipe may beused to ground electrical outlets in the home.Failure to maintain this ground path may resultin an electric shock hazard. If the cold waterpipe is used to ground electric outlets, pleaserefer to Installing the Ground Wire sectionbefore cutting the pipe.IMPORTANT: This water softener has a non-metallic valve system. Installing it on metalplumbing will break electrical continuity, which mayinterrupt grounding for the home. You must restoreelectrical continuity in your metal plumbing system.If you install a 3-valve bypass system (Figure5), electrical continuity will be maintained. If youinstall the non-metallic bypass valve (Figure11), please refer to the Installing the GroundWire section before cutting the pipe.Measure, cut, and loosely assemble pipe andfittings from the main water pipe to the inletand outlet ports of the water softener valve. Besure to keep fittings fully together, and pipessquared and straight.BE SURE INCOMING HARD WATER SUPPLYIS DIRECTED TO THE SOFTENER VALVEINLET PORT.NOTE: Inlet and outlet are marked on the watersoftener valve. Trace the water flow direction tobe sure hard water is to inlet.IMPORTANT: Be sure to fit, align and supportall plumbing to prevent putting stress on thewater softener valve inlet and outlet. Stressfrom misaligned or unsupported plumbing maycause damage to the valve.• If making a soldered copper installation, do allsweat soldering before connecting pipes tothe NPT adapters and bypass valve. Torchheat will damage plastic parts.WARNING If solder is usedto make pipeconnection use only lead free solder andflux to prevent lead poisoning.• When turning threaded pipe fittings ontoplastic fittings, use care not to cross-thread.• Use Teflon Tape on all external pipe threads.Complete the inlet and outlet plumbing for thetype of pipe you will be using. Secure groundclamp to metal pipes.INSTALLING THE GROUND WIRENOTE: If your house plumbing is plastic, itwould not be used as a grounding path, andthis step should be skipped.IMPORTANT: A copper or galvanized coldwater pipe is often used to ground electricaloutlets in the home. Grounding protects youfrom electrical shock. The water softenermay have broken this ground path. To restoreconnection, install a 12”-long, 6-gaugecopper wire across and tightly clamp usingUL-approved 1/2”–1” bronze grounding clampsat both ends as shown (Figure 12). Zinc clampsshould not be used on copper plumbing. Wireand clamps may be purchased separately fromyour local hardware store.1. Clean copper pipe and ends of wire with emerypaper. Bare wire is recommended. If insulatedwire is used, is should be stripped 3/4” at eachend before cleaning with emery paper.2. Attach bronze clamps to pipe. Tighten screws.3. Attach to clamps as shown. Tighten screws.NOTE: If you are installing a sediment filter orother item(s) into the plumbing system, along withthe water softener, be sure to restore electricalcontinuity across all removed metal pipe sections.Figure 11Figure 12Ground WireClamp (2)Installation Instructions
