Sump penetrations space between the primary and the secondary,provide sufficient length of primary pipe <br /> (cont.) to accommodate both the closure pieces and the fiberglass bell x female threaded <br /> adapter which terminates the primary. <br /> To install 3 x 2 reducing closures,sand the sump fitting,the exterior of the primary pipe <br /> for about 1'k inches where the small end of the closure pieces will fit(Fig.9-4),and the <br /> bonding surfaces of the closure pieces(Fig.7-6).Apply liberal amounts of adhesive to <br /> the sanded areas and bolt the closure halves together. <br /> The containment system annular space can also be sealed off and isolated from the <br /> sump by means of <br /> By others Riser special sump <br /> Fig.9-4.Sand the bonding surfaces penetration fittings <br /> of the sump penetration fitting,the <br /> primarypipe,and the reducing - that permit direct <br /> closure pieces before applying connection of 1 lb or <br /> PSK-20 adhesive. ! 2-inch flex con- <br /> nectors to the <br /> Sand shaded areas penetration fittings <br /> themselves on the <br /> By others Riser <br /> inside of the sump. <br /> Annular space This configuration <br /> Fig.9-5.Sump penetration fittings are open provides more space <br /> available from the factory with 19h-and in the sump.These <br /> 2-inch NPT female threads on the inside dia <br /> fittings also <br /> and 2-inch female tapered bell ends on <br /> the outside that permit direct connection incorporate tapered <br /> of flex connectors and product lines. Annular space <br /> sealed at the female bell ends on <br /> factory the other end,thus <br /> permitting direct <br /> bonding of 2-inch primary pipe to the penetration fittings on the outside of the sump. <br /> On the outside of the sump,join the containment pipe to the penetration fitting with the <br /> following: <br /> 1) Full-length 3-inch containment couplings;or <br /> 2) Half-length 3-inch containment couplings as shown in Fig.9-7. <br /> By others Riser <br /> Ann larspace <br /> open <br /> open <br /> Fig.9-6.The sump penetration fittings <br /> shown in Fig.10-5 are also available <br /> with factory-installed mondonng ports <br /> that can be used in place of the ported <br /> reducing closure shown in Fig.9-3. <br /> A"sealed <br /> installed at factory <br /> Riser <br /> I <br /> Fig.9-7.Join containment piping to — ———— — ——— <br /> sump penetration fittings by means of <br /> containment couplings ITT_ _ ___ _ <br /> 10 <br />
