• • • F9. Install Polyethylene Top and Backfill After completing all piping and electrical piping connections: • Verify final grade. • Trim top of turbine enclosure (if necessary). • Place polyethylene top over turbine enclosure. ❑ This top is designed to prevent water runoff from entering turbine enclosure only. • Position top and press down to seat the top onto the turbine enclosure. • Backfill to turbine enclosure top.

Top Clearances Important: Isolate Turbine Enclosure From Direct Traffic Loading After backfilling to top of turbine enclosure: • Place 1-1/4" of specified gravel and then 3/4" thick PI p. (4' x 4') over top (but not over lid) to allow a 2" minimum clearance between to of turbine enclosure and bottom of concrete surface pad. ❑ This 2" clearance also provides a channel for water runoff. If the tank is located in a traffic area: • Pour 9" thick traffic slab with extra rebar reinforcement directly onto plywood. F11. Sealable Turbine Enclosure Do Not air pressure test sealable turbine FAwARNING enclosure. See Section F7 for testing meth- ods. Scalable turbine enclosures must be iso- fated from direct traffic loading. To prevent water infiltration in high groundwater con- ditions (sealable turbine enclosures are not product tight) sealable turbine enclosure must: • Be mounted and cemented to secondary containment col- lar using same procedure described in Section F5. • Have its top mounted and cemented in place. • Use electrical couplings kit provided by Fluid Containment. • Use seal off fittings to make electrical wiring connec- tions leak free. (If it is to be leak tested using standing water test). • Use FRP couplings for pipe connections. Do not use rub- ber grommets which are not watertight and will leak in high groundwater conditions. • Always vent sealable turbine enclosure. The 2" lid fit- ting can be used as a vent with piping leading to a point above the groundwater table. To adjust for final burial depth: • Trim bottom of sealable turbine enclosures or bottom of fiberglass sealable turbine enclosure top. • Cement in place using Kit AD and allow adhesive to cure. • Torque lid bolts to 25 ft. -lbs. Follow ASTM specifications for"Structural Structural Joints Using ASTM A325 or A490 Bolts". • The gasket is a maintenance item which will have to be replaced periodically or when it shows a leak during a tightness test. • Test both joints of sealable turbine enclosure using stand- ing water test described in section F7.
