PROPERLY INSTALLED SWIVEL COUPLING b Pipe seated in ferrule Primary Secondary a Jacket Ferrule properly seated to insert shoulder. Primary pipe pushed to the front of the ferrule inside over all barbs at insert. IMPROPERLY INSTALLED SWIVEL COUPLING b End of Primary Primary Pipe / 1 M Secondary a Jacket a. Notice ferrule not pushed to insert shoulder. b. Piping not pushed over barbs completely. 13.6.7 Positioning Coax Pipe Coupling Install the appropriate size faceplate, unscrew and remove the tapered swage from the threaded shaft. Lubricate the inside of the coupling insert with metal assembly paste or white lithium grease. Insert the pipe coupling assembly over the threaded shaft and push it down onto the face plate. 13.6.8 Installing The Tapered Swage Thread the tapered swage onto the threaded shaft until it meets the back of the pipe coupling assembly. NOTE: Do not use silicone based lubricants. Be sure that the swivel nut of the pipe coupling assembly is flush against the face plate. 13.6.9 Inserting the Pipe Insert the end of a flexible pipe section inside the pipe coupling until it bottoms out. Inspect the entire assembly, prior to 13 F/e-*W Q R KS BY OPW FUELING CONTAINMENT BYSTEMB switching on the machine. Make sure the pipe is completely vertical. • Finish the coupling process as described in 13.6.5 and 13.6.6 IMPORTANT: For direct burial (non -Access Pipe) coax applications, loosely pre -install entry boot on pipe, studs facing downward, prior to inserting pipe on coupling. Replace orange dust cap after couplings. 13.7 Installing Pipe Sections - Direct Burial (non -Access Pipe) Once the pipe has been measured and the couplings have been installed, the pipe may be installed. This section discusses the installation in a direct burial application. Refer to section 13.8 for installation of the piping using Access Pipe. 13.7.1 Insert Piping Through Sump Wall Take the pipe section to the trench and insert into the containment sump through the flexible entry boot. Make sure the band clamp of the entry boot has been removed or sufficiently loosened to permit the pipe to pass through the rubber boot. Tighten band clamps of the entry boots after the installation process has been completed. For junction sump applications, repeat procedure for adjoining pipe sections. IMPORTANT: For direct burial (non -Access Pipe) coax applications, be sure to insert coupled pipe through opening in the side of the sump. Align studs of the flexible entry boot with stud holes in sump and push into place. Fasten the entry boot according to the installation instructions included with the boot. 13.7.2 Pipe Connection After the flexible pipe(s) have been inserted, attach pipe to fittings using the methods described in section 14. Inspect the piping in the trench to make sure it is positioned properly in the trench between the containment sumps and there is sufficient pipe weaving back and forth to allow for pipe expansion and contraction. 13.8 Installing Pipe Sections -Access Pipe Once the pipe has been properly measured, the couplings have been installed and dust covers placed back on the couplings, the pipe is ready to be installed into the duct. Refer to section 10 and Access Pipe installation instructions for details involving the proper installation of the duct conduit. 13.8.1 Fishing Pipe Through Access Pipe Remove Access Pipe conduit from entry boots. Attach the appropriate OPW-FCS bullnose to one coupling. Fish rope through the Access Pipe conduit and attach to bullnose. Pull or push flexible piping through Access Pipe conduit.
