Ji.,; 17 ZUi! <br />ENVIRONMENTAL HEALTH <br />EERAPTMEN'T <br />Dualoy 3000/LCX molded termination assembly to seal off <br />secondary containment. <br />2" (50 mm) available is with or without test valve; 3 and 4" (75 <br />and 100 mm) are available only with test valve <br />Terminating Containment Inside The Sump <br />The means of terminating the containment on the branch leg <br />of a tee (series lay -out) or the downstream leg of an elbow <br />(parallel lay -out or last sump of a series lay -out) is done with <br />a bonded termination adapter. The adapter is bonded to the <br />exterior of the primary fitting leg to be terminated, prior to the <br />clamshell containment fitting being placed on the assembly. <br />• Lightly sand the outside surface of the leg of the primary <br />fitting on which the termination is to be bonded. <br />• Abrade the inner surface of the termination adapter also, <br />to provide a fresh surface to which to bond. <br />• Cut the tapered end portion of the containment fitting leg <br />which is to be terminated. Abrade the inner surface of the <br />shortened leg of the containment fitting to prepare it for <br />later bonding. <br />• Apply a moderate coating of adhesive to outer surface of <br />the primary fitting and the inner surface of the termination <br />adapter. Keep the outer surface of the adapter dry and <br />free of adhesive. <br />• Fit the adapter onto the primary fitting. <br />• Dry fit tapered Dualoy 3000/LCX pipe leg(s) into the bell <br />ends of the primary fitting which is not terminated, if this <br />procedure is done prior to bonding the primary fitting into <br />the system (recommended). <br />• Place the clamshell containment fitting over the primary <br />fitting -adapter assembly and hold in place with bolts <br />while the adhesive cures. This will assure proper align- <br />ment of the adapter for final assembly. Care should be <br />taken to assure adhesive does not touch the clamshell <br />fitting at this point as it is to be removed when the adhe- <br />sive between the primary fitting and the adapter is cured. <br />• Once the adhesive has cured, remove the bolts and the <br />clamshell fitting. If this procedure was done prior to bond- <br />ing the primary fitting into the system, install according to <br />standard procedures. <br />• Use the prepared clamshell fitting to close the contain- <br />ment system when primary testing and inspection is <br />done. <br />69 <br />
