A <br />E3. ELECTRICAL COUPLING INSTALLATION ATTACH STEEL COUPLING <br />Provides watertight seas at piping penetration for high <br />groundwater conditions. <br />♦ Threaded steel couplings connect to electrical conduits <br />♦ Two fittings are provided in optional electrical fitting <br />kit to accommodate wiring to submersible pump and <br />optional monitoring sensor (see Section D9). <br />All wiring connections must conform to local and na- <br />tional electric codes. <br />Installation kit Includes: <br />• Two piece 1" steel coupling Adhesive <br />• Mixing stick Sandpaper <br />• Putty knife • Instruction sheet <br />NOTE: <br />Contractor must supply a jig saw or hole saw (2" <br />diameter) to cut hole for fitting. <br />HOW TO INSTALL ELECTRICAL STEEL COUPLING - <br />SEE FIGURE 39 <br />CUT HOLE <br />Step I <br />Drill 2" diameter hole (using contractor supplied car- <br />bide tipped or masonry hole saw) at marked coupling <br />location. <br />SAND AND CLEAN <br />Step I <br />Use supplied sandpaper (60 grit) to sand area <br />around drilled hole on both inside and outside of <br />turbine enclosure. <br />NOTE: <br />• Turbine enclosure must be sanded "white" to <br />insure proper bond. <br />• Sanded area should radiate at least 3" out from <br />hole edges. <br />Step 2 <br />Sand inside of flanged faces of both coupling sec- <br />tions. <br />Step 3 <br />Use clean, dry cloth to clean sanding dust from all <br />sanded surfaces. <br />MIX AND APPLY ADHESIVE <br />NOTE: Mix adhesive in accordance with instructions <br />in adhesive kit. Adhesive shelf life is sixmonths. <br />Step I <br />Make sure all surfaces are dry. <br />Step 2 <br />Follow Adhesive Application Guidelines in Section D4. <br />Step 3 <br />Apply adhesive to prepared surfaces on both fiberglass <br />turbine enclosure and coupling flanges. <br />26 <br />Step I <br />Insert male threaded coupling section from outside of <br />turbine enclosure. <br />Step 2 <br />Screw female threaded section onto male section from <br />inside of turbine enclosure. <br />Step 3 <br />Tighten down both sections by hand tightening until <br />adhesive is squeezed out from flange faces. <br />Step 4 <br />Use flat stick or supplied putty knife to fill in all gaps <br />around fitting flange/turbine enclosure joint. <br />CURING <br />Step <br />Allow minimum of four hours for adhesive to harden <br />completely. <br />NOTE: Do not move or impact coupling during hard- <br />ening process. <br />Step 2 <br />Complete successful test of the steel coupling. <br />NOTE: See Section D8, hydrostatic water test for <br />details. <br />Step 2 <br />Install conduit onto the coupling. <br />1" Steel Coupling <br />Female <br />Section <br />J7ine EnGosure'eviin <br />*nor) <br />Male <br />Section <br />Sand inner surface of coupling and ouler surface <br />of fiberglass pipe. <br />DISPOSE OF UNUSED CATALYST, ADHESIVE <br />Step 1 <br />Mix unused tubes of catalyst and any unused adhesive <br />(as described above) to form a solid for safe disposal. <br />Step 2 <br />Dispose of resulting solid as a nonhazardous waste in <br />accordance with federal, state and local regulations. <br />
