Adhesive Application Guidelines (con't) Hot weather (above 85°F): • Apply adhesive more rapidly (it will harden in 15 mins.). • (Alternate) Cool the adhesive to 60°F to slow down chemical reaction. ❑ Increases allowable application time. When required for FRP coupling: • Recommended method for supplemental heat is a hand held heat gun (maximum output temperature 200T). Important: Mix unused tube of catalyst and any un- used adhesive to form a solid for safe disposal. Then dispose as a nonhazardous waste in accordance with federal, state and local regulations. F6. Piping Connections Secondary piping can be connected to the turbine enclo- sure using the field installed 3" or 4" FRP coupling (avail- able from Fluid Containment as optional fitting kits). FRP coupling • Provides watertight seal at piping penetration for high groundwater conditions. • See Section G3 for detailed installation instructions. FRP Coupling Detail I�I Turbine Enclosure Exterior To minimize water infiltration in turbine enclosure, FRP couplings or steel electrical couplings: • Can be installed anywhere on the turbine enclosure, ❑ Provided they do not interfere with adhesive channel. ❑ Must be aligned radially to turbine enclosure center. F7. Hydrostatic Water Test Failure to properly test and seal joints AWARNING may result in product loss, environmen- tal damage, explosion or fire. HDPE Lid (Non Sealable) Model To test joint seal between the collar and turbine enclosure: • Fill turbine enclosure with water at least 3" above joint seal. • Record the liquid level. 22 F7. Hydrostatic Water Test (con't) • Wait 24 hours. • Remeasure and record the liquid level, ❑ A liquid change more than ''h" indicates a possible leak. To test seal of field mounted fittings: • Fill turbine enclosure with water at least 3" above fit- tings • Record liquid level. • Wait 24 hours. • Remeasure and record liquid level ❑ A liquid change more than '/." indicates a possible leak. Sealable Model • A 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 enclosure using a standing water test, described below. To test both adhesive joints and lid seal: • Attach a 2" pipe to the 2" lid fitting ❑ Test before other piping connections are made through the turbine enclosure. OR ❑ Block off the secondary containment pipes. • Fill the enclosure until water is between l foot and 5 feet high in the standpipe above the lid. • Wait 3 hours. • Record the water level in pipe. • Wait 4 hours. • Remeasure and record the water level in the pipe. Cl A liquid level change of more than I" Indicates a possible leak. If no leak is indicated: • Remove all water. Failure to remove water may result in collar freeze rupture during winter. • Continue normal operation. If a leak is suspected: • Contact Fluid Containment Field Service. Phone num- ber listed on page 2. F8. Electrical Connections Installing electrical fittings on turbine enclosures: • All wiring connections must conform to local and na- tional electric codes. • Connect electrical conduits to threaded steel couplings ❑ Four fittings are provided in optional electrical fit- ting kit to accommodate wiring to submersible pump and optional monitoring sensor (see section 155).
