Insulating washers shall fit vithin the bolt facin� on <br /> tha flange over Che outside diameter of the sleeve. <br /> 4. Washers: Steel, cadmLum plated, to fit vithin the bolt facing on <br /> the flanga. <br /> E. Thermite Weld Equipment: Exothermic weld equipment specifically <br /> designed by the ¢anufacturer for Nelding the types of materials and <br /> shapes indicated. <br /> F. Electrlcal Insulating Coatings: MIL-C-18480. Conformable water-tight <br /> sealant having dielectric strength not lesa than 15 kV for a 1/8" thick <br /> layar. <br /> G. Tharmite Weld Caps: Molded elastic ca�, 4" x 4" with 1-5/8" diameter x <br /> 0.8" high dome, filled with corroaion-realstant compound on base of <br /> elastomaric tape; Royston Handy Cap 2 with Royston Roybond 747 primer, <br /> or approvad equal. <br /> PART 3 - EXECUTION <br /> 3.01 �NSTALIATION: <br /> A. NFP9 70 and ANSI C2. <br /> B. Anodea and Lead Wires: Install each anode and lead wirn at the <br /> indicated locations as follows: <br /> ,� 1. Excavation for Anode: Auger 10" diametez hole or dig with backhoe <br /> for each anode to a dapth t2iat vill place �:he top of the anode no <br /> lesa than 3 feet beloa the bottom of the pipe(s) . <br /> 2. Lifting Anodee: Do not llft ot aupport anodn by the lead vire. <br /> Exercise care to pravant damaging ehe cloth bag and lead wira <br /> insulation. <br /> 3. Installing Anode, Soil: Center tha packaged anoda in the hole and <br /> beckf111 vith native aoil free of rocks and organic material in <br /> layars nat excaeding 6" deep. Tamp each layer to remove voids. <br /> When the backfill ia 6" above the top of the anode, pour not lesa <br /> ehan 5 gallona of vater into tha hole. <br /> 4. Connecting/Terminating .lnode Lead Wiree: Connect anode lead wirea <br /> directly to teat station and terninata �s ehown. <br /> G. Connecting Test Lead WSres and Bondin�t Cablee: Conn�ct to the pipes by <br /> use of a tharmite weld as indicated. Clean the surface by filing to <br /> produce a clean, bright aurfaca. Inntall the thermite veld in <br /> accordanca with the manufacturer's inatructiona. Cover connectiona <br /> with a thermite weld cap and electrical inaulating coating. <br /> D. Teat Stations: Install tha teat atationa •t the indicated locationa. <br /> Set the atations Level, the tops fYush vith tha concrete surface or <br /> grade. <br /> 1. Terminetion of Test Lead Wirea: Tarminate test lead virns inside <br /> test atation on terminal board as aharn using ring-type crimp on <br /> terminals on anda of virea. Provida sinimum of 18" of alack in <br /> each �rire inaide test etation. <br /> 2. Verlfy that one test lead connects to enodn lead wite through <br /> \ shunt. <br /> l <br /> BOE15180.911 15180-3 <br />
