SECTION 2 ♦ System Preparation quired for joining secondary containment fittings, it is recommended that only DS -7014 or DS -8014 and DS -7069 or DS -8069 kits be used. SECTION 2 • SYSTEM PREPARATION 2.2.1 Piping Layout Before installing the secondary containment piping sys- tetn, review and verify the recommendations for proper installation set forth in the following sections: 1. Inspection — Refer to Part One, Section 2 2. Installation Crew Size and Organization — Refer to Part One, Section 2 3. Piping Layout, Pipe Trenches, and Burial — Refer to Part One, Section 6 Most of the standard procedures for installing a secondary containment piping system can be handled by the same size crew that would install a single-wall product piping system. It is essential that each phase of an installation be evaluated and the proper number of workers be assigned to assure an efficient installation. 2.2.2 Pipe Preparation and Tool Set-up and Use Cut off factory spigots and couplings as needed. Couplings may be needed for making containment pipe size reductions or straight pipe runs. Spigots may be need- ed for pipe runs or for making a containment sump con- nection. The ends of the containment pipe that are to be joined to secondary containment fittings must be thoroughly scarfed or sanded for a minimum length of 3 inches (75 mm). Any surface irregularities must be removed. This procedure is most easily accomplished by using the Model 2100 power tool available from Smith Fiberglass Products Inc. Preset at the factory, it can scarf 3" and 4" (75 mm and 100 mm) RED THREAD IIA secondary con- tainment pipe. (It also tapers 2" and 3" (50 mm and 75 mm) RED THREAD IIA primary pipe; see Part One of this manual.) Refer to Smith Fiberglass Products' Bulletin No. F6625 for operating instructions. If the power tool is not available, the ends may be scarfed using the Smith Fiberglass Products' manual tapering tool in conjunction with the secondary containment scarfing adapter kit (also from Smith Fiberglass Products). This kit consists of a special scarfing blade (approx. 4"/100 mm long), scarfing blade holder, W alien wrench, and 3" and 4" (75 mm and 100 mm) scarfing gauges, which are re- quired to set the tool tolerances. The scarfing adapter kit is easily adapted to Smith Fiberglass Products' 2"-6" (50 mm -150 mm) manual tapering tool kit. Assemble the proper size mandrel and scarfing blade hold- er following the procedures in Bulletin No. F6600, Installation Instructions for 1 "-6" Tapering Tool. Rotate the tool body so that the scarfing blade holder is at a 12 o'clock position (see Fig. 2.2.1); this assures that the blade will rest on top of the gauge. Slide the proper size gauge all the way to the back of the mandrel. Insert the special blade into the blade holder all the way to the back of the tool body. After positioning the black reference mark on the gauge under the blade, be sure that the blade makes uniform contact with the gauge and that the blade holder is resting on the blade. Using the nuts, bolts, and washers supplied, tighten the blade holder to secure the blade. Now insert and slide the bearing plate into the slot located between the tool body and the blade holder. The bearing plate will rest loosely on the blade holder until it is locked into place using the supplied alien screws. The two ailen screws should now be positioned so that each makes LIGHT contact with the bearing plate (see Fig. 2.2.1). NOTE: The alien screws only prevent the blade holder from opening during use. The tool is now prepared to remove ("scarf") the resin gloss from the ends of the containment pipe. After re- moving the gauge, insert the tool into the pipe to be scarfed until the point of the blade just touches the end of the pipe. Note: The tool must be rotated in the same di- rection the wide side of the blade faces. Advance the tool in approximately /" (6 mm) increments after each revolu- tion. Continue the operation until the resin gloss has been removed for a minimum length of 3" (75 mm). An alternate method to prepare pipe ends is to sand with 30-40 grit sandpaper or emery cloth to remove all surface gloss. Belt sanders, power grinders, or a coarse -cut flat file may also be used. The sanded length must be a minimum of 3" (75 mm).
