Preparation 1. Disconnect power to the submersible pump at the electrical supply box(if already installed). 2. Tag and lock out electrical circuit breakers so they are not turned on accidentally. If the electrical circuit breakers are accidentally turned on while installing a leak detector, there Warning A is the possibility of ignition of hydrocarbon vapors, and/or the installer being bathed in gasoline, which could result in serious personal injury or death. ALWAYS tag and lock out breakers so they are not turned on accidentally. Before commencing the installation of a leak detector, use safety cones, barricades,trucks, etc, Warning A to isolate the work area. Relieve line pressure by using the manual pressure relief (if present), or by loosening a pipe Caution 0 plug either in the manifold cover of the STPIIST or in the shear valve under a dispenser. Make adequate provision to trap the liquid that escapes to prevent contamination of the environment. Re-tighten the pipe plug or manual pressure relief. 3. Remove the two-inch pipe plug or old leak detector from the submersible pump or the adapter tee. 4_ Examine the straight bore below the two-inch threads for roughness caused by corrosion. If rough, smooth with fine emery paper. 5. Apply UL-classified non-hardening, non-toxic pipe thread sealant to the two-inch threads on the leak detector,and lubricate the O-ring with grease or oil. Make sure the manifold cavity and STP-MLD threads are dry, clean and free from any debris. If wet,thread sealant may wash off of the applied areas and weeping may result. 6_ Screw the leak detector into the pump or adapter tee, and tighten with a 1'/" socket or pipe wrench on its hex top. The STP-MLD must be properly torqued into the manifold to provide a good seal (minimum of 138 foot-pounds) (see Figure 2), 7. Remove the plastic dust cover from the vent port at the top of the leak detector. 8. Remove the 1/4-inch plug from the TANK PORT on the pump. Apply UL-classified, non-hardening, non-toxic pipe thread sealant to the threads on the tubing fitting and install one 9011 fitting in the leak detector vent port and either a 900 or straight fitting in the tank port. Take steps to prevent any foreign materiats from getting into the top of the leak detector as Caution Q damage to the sealing surfaces in the piston area could result, preventing the leak detector from operating correctly. The FE Petro STP/IST's have two labeled ports,one for the syphon system and one for the tank. Caution 0 The leak detector must be vented to the tank port only. This is the port closest to the tank. Do not connect a leak detector to the syphon port, as this will make the leak detector inoperative, causing it to be incapable of detecting a leak, with resulting risk of contamination of the environment(see Figure 2). 9. Install the copper tube packed with the STP-MLD into the compression fittings just installed in step 8 above, and tighten firmly. The tubing may be shortened_ This line vents the air displaced by piston travel, and drains any liquid,which may leak past the Caution Q piston seal. When installing this tubing make sure it is not crimped and that it will drain properly to the tank,or the leak detector will not open properly and could give a false indication of a leak. Failure to install and connect this tubing could result in environmental contamination. 10_ Tum power on at the load center and turn on the submerged pump at a dispenser. Look for leaks at the parts just worked on. If there are any leaks, immediately turn off the pourer at the load center, tag and lock out the breaker, and repair the leaks. 4
