.f <br />E1. FRP COUPLING INSTALLATION <br />Note: Do Not Use this Field Installed FRP Coupling in <br />Primary Piping. <br />♦ Secondary piping can be connected to the turbine <br />enclosure using the field installed 3" or 4" FRP cou- <br />pling (available from Containment Solutions as optional <br />fitting kits). <br />♦ Coupling is designed as a secondary containment fit- <br />ting. <br />❑ Outer jacket of double-wall piping is connected to <br />FRP coupling. <br />❑ Primary piping passes through FRP coupling. <br />♦ Provides watertight seal at piping penetration for high <br />groundwater conditions. <br />♦ Must be aligned radially to center of turbine enclosure <br />(to minimize potential for water infiltration at piping <br />penetration). <br />FIGURE 34 <br />Correct Incorrect <br />Alignment Alignment <br />Turbine <br />Enclosure <br />(trop view) <br />The FRP couplings and grommets should be aligned radially <br />to the center of the to rbine enclosure 1 piping sump, <br />24 <br />correct p0,8rnonrng orthe MO. <br />The fitting does not irW ere wilh the <br />adhesiveehenhel beam <br />Inoorrett posrtlaning of the lii6ngs. <br />The riling ntarieres trih the adhesive <br />channel scam <br />♦ Should be placed to not interfere with adhesive channel <br />of turbine enclosure (see figure 35). <br />FRP coupling (3" and 4" diameter) kit includes: <br />• Two piece fitting Adhesive <br />• Mixing stick Putty knife <br />• Sandpaper Instruction sheet <br />NOTE: Contractor must supply a jig saw or hole saw <br />(4'/z" diameter for 3" coupling or 5'/2" diameter for 4" <br />coupling) to cut hole for fitting. <br />HOW TO INSTALL FRP COUPLING: <br />CUT HOLE <br />Step 1 <br />Layout piping trench. <br />Step 2 <br />Mark location of fittings on turbine enclosure. <br />Step 3 <br />Use a hole saw (41/2" diameter for 3" coupling, 5%2" <br />diameter for 4" coupling) or jig saw (both provided by <br />contractor) to cut a hole at marked location. <br />NOTE: Although carbide tipped blade will last <br />longer, any steel saw blade can cut the hole. <br />SAND AND CLEAN MATING SURFACES (SEE FIGURE 36) <br />Step 1 <br />Use supplied sandpaper (60 grit) to sand an area <br />around drilled hole on both inside and outside of tur- <br />bine enclosure. <br />NOTE: <br />• Turbine enclosure surface must be sanded "white" <br />to ensure proper bond. <br />• Sanded area should radiate at least 3" out from hole <br />edges. <br />Step 2 <br />Sand FRP fitting flanged surfaces. <br />
