El the removal of a 22" manwav lid. The ofid OD must be small enough to be removed through a 36" street box. The enclosure body must be capable of joining to the 42" or 48" diameter secondary contain- ment collar with a leaktight adhesive joint. The reducer must be capable of joining to the enclosure body with an external leaktight adhesive joint to allow for field installation of the adhesive without entering the enclosure. With the lid installed, the assembly must provide a watertight seal with water up to 12" over the lid. The lid includes a non-skid exterior surface and must be able to support a person standing on the lid without damage to the lid. One of the lid handles is to be offset to aid in the removal of the lid and the other is cen- tered on the lid. Cut lines for field trimming will be marked on the bottom 12" of the enclosure body in 3" increments. 11 Model No. Length Model No. Length WTE42-2 2' WTE48-2 2' WTE42-3 3' WTE48-3 3' K.

H. Sealed FRP Turbine Enclosure (Model STE Series) - The sealed turbine enclosure consists of a fiberglass reinforced plastic (FRP) enclosure body (variable length, 42" or 48" ID's), an FRP reducer (42" or 48" ID's) with an oval flanged manway (23"x29" ID's), a flat gasket, SS bolts with non -galling silicone - bronze nuts (or optional bolt ring), and an oval FRP lid with handle. The reducer opening must be large enough (minimum 28") to allow for the removal of a 22" manway lid. The lid OD must be small enough to be removed through a 36" street box. The enclosure body must be capable of joining to the 42" or 48" diameter secondary containment collar with a leaktight adhesive joint. The reducer with oval flanged manway must be capable of joining to the enclosure body with a leaktight adhesive joint. With the lid installed, the assembly must provide a watertight seal with water up to 7' over the lid. The lid may be supplied with an optional 6" NPT fitting with plug which can be used as an observation port. Cut lines for field trimming will be marked on the bottom 12" of the enclosure body in 3" increments. Refer to Section H for the adhesive kit (to bond the enclosure body to the contain- ment collar and to bond the reducer to the enclosure body) and Sections K, L, M and N for the field installed fitting kits (for electrical and plumbing connections to the turbine enclosure). Turbine Enclosure Adhesive Kit (Kit -AD) - When properly installed and cured, the adhesive kit provides a water tight seal to prevent the ingress of water. The adhesive kit includes 1/2 gallon of adhesive in a one gallon capacity can. The kit also includes catalyst (hardener), a wooden mixing stick, a three inch wide plastic putty knife, 60 grit sandpaper, and installation instructions. One adhesive kit is required for each turbine enclosure; the watertight and sealed turbine enclo- sures require two kits. Field Entry Boot - (Model FEB -3 or FEB -4) The FEB -3 or FEB -4 is designed to interface with 3" or 4" nominal OD FRP pipe. FRP Coupling Kit - (Kit FC -3 or FC -4) is designed to interface with 3" or 4" nominal OD FRP pipe manufactured by Ameron or Smith Fiberglass. The coupling ID is tapered at both ends. The two-piece coupling is constructed of fiberglass reinforced plastic and is field - installed using the supplied adhesive. Both pieces of the fitting are threaded together to hold the fitting in position while the adhesive cures. Kit FC -3 or Kit FC -4 includes one 3" or 4" nominal ID FRP coupling, adhesive, catalyst (hardener), plastic mixing stick and applicator, 60 grit sandpaper, and installation instructions. The contractor must provide the hole saw (4-1/2 or 5-1/2 inch OD) or reciprocating saw to cut the hole in the turbine enclo- sure prior to installing the FRP coupling. L. Electrical Coupling Kit - Kit EC -1 is designed to interface with one inch steel electrical conduit. The two-piece coupling is constructed of steel and is field installed using the supplied adhesive. Both pieces of the fitting are threaded together to hold the fitting in position while the adhesive cures. 19 Model No. Length Model No. Length STE42-2 2' STE48-2 2' STE42-3 3' STE48-3 3' STE42-4 4' STE48-4 4' STE42-5 5' STE48-5 5' STE42-6 6' STE48-6 6 N Kit EC -1 includes two one inch steel couplings, adhesive catalyst (hardener), plastic mixing stick, 60 grit sandpaper, and installation instructions. The contractor must provide a two inch hole saw or reciprocating saw to cut the hole in the turbine enclosure prior to installing the steel coupling. Secondary Containment Collar - The secondary containment collar shall be constructed of fiberglass reinforced plastic Collar shall be 42" or 48" in diameter and will be factory -installed in accordance with drawings. The collar will include a sensor mounting bracket. Containment Collar Sensor is pre - assembled and ready to wire. All electrical components must be U.L. listed or accepted. This float switch sensor is capable of detecting a 2" or more accumulation of liquid (water or product) in the turbine enclosure. The float switch is constructed of Buna-N; the float switch is housed in plastic casing and includes a mounting clamp. O. Ladders - Ladders shall be the standard ladder supplied by the tank manufacturer (carbon steel, stainless steel, aluminum). Refer to drawings for location. P. Tank Lifting Lugs - Provide lifting lug(s) on all tanks. Lifting lug system shall be capable of withstanding weight of tank with a safety factor of 3:1. 0. Probe Drawstring - Nylon line shall be 150 Ib. break strength located at the monitoring fitting nearest the end of the tank. When a reservoir is located at this position, the drawstring shall be installed within the reservoir. Drawstring length will allow for a 7' tank burial depth. R. Fittings Threaded — NPT 1. All threaded fittings on U.L. labeled tanks shall be located in a manway lid or a tank mount within 12" of the tank top center line and be constructed consistent with the requirements of the U.L. label. Fittings to be supplied with threaded cast iron plugs. 2. All standard threaded fittings to the pri- mary tank and monitoring cavity are 4" in diameter. The standard secondary containment coupling is 6" in diameter. All standard threaded fittings are half couplings. Reducers are to be used for smaller sizes where specified and provided by contractor. 3. Thread Standards — All threaded fittings shall have machine tolerances in accordance with the ANSI standard for each fitting size. 4. Strength — Primary tank NPT fittings will withstand a minimum of 150 foot-pounds of torque and 1,000 foot-pounds of bend- ing, both with 2:1 factor of safety. 5. Sizes Standard Reducer Sizes Inlet 4" Outlet 4" Vent 4" Gauge 4" Fill 4" 6. Location — Refer to drawings for location. 7. Suction Line — Shall be installed on site by the contractor. Diameter of pipe and grade and schedule as called out in other sections. 8. Return Line — Shall be installed on the site by the contractor.
