Installation kit includes: • Two-piece 1 " steel coupling. • Adhesive. • Mixing stick. • Sandpaper. • Putty knife. • Instruction sheet. How to Install Electrical Steel Coupling Step #1- Cut Hole • Drill 2" diameter hole (using contractor supplied carbide tipped or masonry hole saw) at marked coupling location. Step #2 - Sand and Clean • Use supplied sandpaper (60 grit) to sand area around drilled hole on both inside and outside of turbine enclosure. ❑ Turbine enclosure must be sanded "white" to insure proper bond. ❑ Sanded area should radiate at least 3" our from hole edges. • Sand inside flange faces of both coupling sections. • Use clean, dry cloth to clean sanding dust from all sanded surfaces. Step #3 - Mix and Apply Adhesive Note: Mix adhesive in accordance with instructions in adhesive kit. Adhesive shelf life is six months. • Make sure all surfaces are dry. • Follow Adhesive Application Guidelines in section F5. • Apply adhesive to prepared surfaces on both Fiberglass turbine enclosure and coupling flanges. Step #4 - Attach Steel Coupling • Insert male threaded coupling section from outside of turbine enclosure. • Screw female threaded section onto male section from inside of turbine enclosure. • Tighten down both sections by hand tightening until adhesive is squeezed out from flange faces. • Use flat stick or supplied putty knife to fill in all gaps around fitting flange/turbine enclosure joint. Step #5 - Curving • Allow minimum of four hours for adhesive to harden completely. ❑ Do not move or impact coupling during hardening process. • For outside temperatures under 60°F, apply heat to assure proper adhesive curing. ❑ Heat may be applied using a heat gun. ❑ See Adhesive Application Guidelines in section F5. 28 • Complete successful test of the steel coupling. • ❑ See section F7. • Install conduit onto the coupling. Step #6 - Disposal of Unused Catalyst, Adhesive. • Mix unused tubes of catalyst and any unused catalyst or adhesive (as described above) to form a solid for safe disposal. • Dispose resulting solid as a non -hazardous waste in accordance with federal, state and local regulations.

Testing Periodic Maintenance If turbine enclosure fittings have been abused, damaged, or worn: • Test turbine enclosure immediately for potential leaks. In normal service: • Use standing water test as described in F7. Note: Leak test turbine enclosure at least once a year. Hl. Other Accessories Compression Rings • Optional steel compression rings are available to connect a piping trench liner (flexible membrane or fiberglass trench liner) to: ❑ The manway cover. ❑ A Fiberglas attachment ring. ❑ A manway interface ring. • When flexible membranes are used, a special caulk (supplied by the trench liner manufacturer) is applied to both sides of the liner before fastening it to the manway flange. Fiberglas Manways • Tighten manway bolts until gasket seals the opening. ❑ Do not exceed 50 foot-pounds during bolt tightening or manway flange damage may occur.
