585A-150. The STP-MLD units call ee used with gasoline, #2 diesel, kerosefany combination of gasoline and ethanol or methanol, up to 20% MTBE and gasoline, up to 20% ETRE and gasoline, or up to 17% TAME and gasoline. STP-MLD-D units are for use with diesel fuel and kerosene only. See Technical Bulletin 002 (T113002) for specifics on STP-MLD, STP-MLD-D, and STP-MLD-E models. The STP-MLD units mount in a 2" NPT threaded leak detector port provided in most submersible petroleum pump manifolds or a special adapter tee housing and may be installed in any position. The piston chamber of the leak detector must be vented to the tank. If your submersible pump does not have a "tank" port, the pump will have to be replaced, a threaded riser must be used, or a different leak detector must be used. All mechanical leak detectors must be tested upon startup, and routinely thereafter (at least annually) under NFPA standards. These NFPA and other industry testing practices must be followed by the installer and the end user. A leak detector is not a substitute for compliance with prudent industry practices. Fuel inventory reconciliation checks must be performed on a daily basis by comparing dispenser meter totalizers with fuel volume changes in the underground tank. INSTALLATION INSTRUCTIONS EE CAUTION Installation of two or more STP-MLD's in parallel into the same product piping system will result in the smallest leak that is detectable being greater than the EPA requirements. Each STP-MLD will detect a leak of 3gph or greater. If two STP-MLD's are in parallel, a leak of 6 gph will be the smallest leak that will be capable of being detected. If three STP-MLD's are in parallel, a leak of 9 gph will be the smallest leak that is capable of being detected, and so on. EE CAUTION Third party tests have approved the use of STP-MLD in pipelines up to 129 gallon capacity with a bulk modulus between 15,000 —35,000 psilml. STP-MLD-D in pipelines up to 370 gallon capacity with a bulk modulus between 15,000 —35,000 psi/mi. • STP-MLD-E in pipelines up to 49 gallon capacity with a bulk modulus of 1,280 psilmi. NOTE A precision line test must be conducted before installing a leak detector for the first time. A precision line test is also recommended before replacing a leak detector that is having slow flow (tripping) problems to assure line integrity. NOTE Before installing the leak detector, purge the system of any air by running the pump and delivering gasoline from each dispenser (starting with the dispenser farthest from the pump), until all air is removed. The leak detector will not work properly until all of the air is out of the system. Required Tools: 1. Standard flat head screw driver, for manual pressure relief. 2. 1 pipe wrench (24" minimum)or a 1-'/2" socket for tightening the STP-MLD into the manifold housing. 3. 9116" and a 112" open end wrench or an adjustable wrench for attaching flexible tubing fittings. 4. UL-classified non-hardening, non-toxic pipe thread sealant. 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. WARNING If y the electrical circuit breakers are accidentally turned on while installing a leak detector, there 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. WARNING Before commencing the installation of a leak detector, use safety cones, barricades, trucks, etc. to isolate the work area. CAUTION 4
