8 PWF Filter SystemsNOTICEWhen assembling the installation fitting package, connectthe fitting to the plumbing system first and then attach thenut, split ring and o-ring. Heat from soldering or solventcements may damage the nut, split ring, and o-ring. Makesure solder joints are cool before assemble is started.Split ring retainer design holds the nut on and allows load to bespread over the entire nut surface area reducing the chance for leak-age. The split ring design, incorporated into the installation fittingsallows approximately 2 degrees off axis alignment to the plumbingsystem. The installation fittings are designed to accommodate minorplumbing misalignments but are not designed to support the weightof a system or the plumbing.When assembling the installation-fitting package, connect the fittingto the plumbing system first and then attach the nut, split ring ando-ring. Heat from soldering or solvent cements may damage the nut,split ring, or o-ring. Solder joints should be cool and solvent cementsshould be set before installing the nut, split ring, and o-ring. Avoidgetting primer and solvent cement on any part of the o-rings, splitrings, and bypass valve or control valve. Solvent cements and prim-ers should be used in accordance with the manufacturer’s instruc-tions.Move Filter System Into Place1. Connect the cold water supply to the inlet of the water condition-ing system. While constructing the supply line, install a mastersupply valve (user supplied) in the supply line and close it.2. Connect the feed water line to the home to the outlet of thesystem.3. Make sure floor is level.Measure, cut, and install pipe and fit-tings to the bypass valve (dry fit only tomake sure you have a proper fit) inletand outlet side. Be sure hard water issupplied to the inlet side. Trace pipeto be sure.The installation fittings connect to thecontrol valve or the bypass valve usingnuts that only require hand tighten-ing. Hand tighten nut connectionsbetween control valve and installationfittings,control valve and bypass valve,and bypass valve and installation fit-tings allow for easy serviceability. Donot use a pipe wrench to tighten nutson installation fittings. Hand tightenonly.Slip the nut onto the fitting first, then the split ring second and theo-ring last. Hand tighten the nut. If the fitting is leaking tightening thenut will not stop the leak. Remove the nut, remove the fitting, andcheck for damage or misalignment of the o-ring.Do not use pipe dope or other sealant on threads. Teflon tape mustbe used on the threads of the 1" NPT elbow and the 1/4" NPT con-nection and on the threads for the drain line connection. Teflon tapeis not necessary on the nut connection or caps because of o-ringseals.Connect the Drain Line1. Plumb the drain line to an appropriate drain abiding by all local,city, and state codes. Use a 3/4” drain line for backwash flowrates of 7 gpm or for drain lines of 7 gpm and less that exceed20’ in length. Use a 1” drain line for backwash flow rates of 10gpm and 12 gpm.2. If the drain line is a 5/8" flexible poly tube, slide the nut onto thepoly tube, then place the poly tube insert into the end of the polytube and tighten the nut on to the 3/4" drain line fitting. The nutis only designed for use with flexible poly tube. Use other nuts ifattaching different materials. Run line to a drain. Making sure youhave a 1 1/2" airgap. You may use a floor drain, standpipe or anyopen type drain (see Fig 7).Do not use Vaseline, oils, or other unacceptable lubricants ono-rings. A silicon lubricant may be used on the black o-ring.Use a pliers or crescent wrench to tighten or unscrew the nut. Donot use a pipe wrench to tighten or loosen nut. Do not use pipedope or other sealant on threads. Use Teflon tape on the threads ofthe drain line control fitting when installing 3/4" NPT or 1" straightfitting.Figure 7: Also be sure drain line has an air gap.
