Do <br /> not over-insert pipe past scarfed area. <br /> Inserts must be used on 3" and 4" 900 elbows and tees <br /> for Closed Interstitial Monitored Systems. Inserts are not <br /> required for Open Gravity Flow Systems. Prior to bonding .,. <br /> the insert, spread the insert splice 3 or 4 times to relax <br /> the insert. The insert may be placed on the containment <br /> pipe or primary fitting for easy access prior to bonding of <br /> the containment fitting. Locate the inserts adjacent to the <br /> inside radius of the containment fitting, as shown on page 17 <br /> drawing "Closed Interstitial Monitored System Inserts." The <br /> split in the insert must be facing up. Do not allow insert to <br /> overlap. <br /> Use the bolts supplied with the clam shell fitting to <br /> assemble the fittings on the pipe. Use of an air or electric <br /> wrench with a magnetic socket will greatly facilitate assembly. <br /> When starting the bolts, allow the bolt to start with minimal <br /> pressure on the tool. Excessive pressure may push the <br /> insert from the fitting. Tighten the bolts alternately and with <br /> equal force. DO NOT EXCEED 8 FT-LBS OF TORQUE. <br /> NOTE: Prior to bonding, make sure the pipe fits snugly <br /> into the socket ends of the clam shell fittings and there are <br /> no gaps between pipe ends and fitting sockets. A properly <br /> bonded joint should have adhesive visible from all bonded <br /> surfaces. <br /> NOTE: Do not disturb a completed containment piping joint <br /> when assembling additional joints. The adhesive must be <br /> fully cured before applying stress to the assembled joints. <br /> Read and observe the filled adhesive instructions supplied <br /> with each adhesive kit. <br /> 22 <br />
