Open the pressure valve all the way and alloy the <br /> line pressure to drop to zero. Leave the pressure valve open all the way. Continue to drain until there is no more <br /> product draining. Turn the submersible pump on at the dispenser and direct the fluid into a suitable receptacle <br /> while observing the pressure gauge,which should not increase above 18 PSI. Tum the submersible pump off <br /> and wait at least one minute. Turn the submersible pump back on at the dispenser and observe that the pressure <br /> does not increase above 18 PSI. This step verifies the leak detector has detected a leak equivalent to <br /> approximately 3 GPH @ 10 PSI as required by the EPA. <br /> 17. Close the leak valve and observe the pressure increase to full pump pressure. Turn the submersible pump off and <br /> drain the pressure back to zero. <br /> 18. Turn the pump of at the load center, and remove the test fixture, and replace the pipe plug after applying UL- <br /> classified, non-hardening, non-toxic pipe thread sealant. <br /> STP-MLD Line Leak Indicator Testing <br /> 19. As a final check to assure the leak detector has been installed and is working properly, before leaving the station <br /> perform the following check(it takes two people to perform this check): <br /> a. Tum the submersible pump on at the dispenser. Dispense product into a five-gallon container to assure full <br /> flow is being obtained. <br /> b. Leaving the dispenser switch turned on, turn the power off at the submersible pump circuit breaker (load <br /> center)and open the nozzle to release pressure. Let stand idle for approximately 15-30 seconds. <br /> c. With the nozzle open, turn on the power at the submersible pump circuit breaker(load center). The flow out of <br /> the still open nozzle should be no more than 3 GPM. <br /> d. Close the nozzle with the submersible pump still running and wait for 15 seconds or until you feel the pressure <br /> increase in the line when the leak detector opens. Open the nozzle and full flow should be obtained. <br /> Note: The submersible pumps and the dispensers must be wired to different circuit breakers for the above test to <br /> work. Also, some dispensers may not allow for this test since low pressure may put it into error(i.e. blender <br /> dispensers), <br /> Note: Instructions 12 through 19 can also be used to check a leak detector after it has been in service for a period of <br /> time to assure it is functioning properly. Mechanical line leak detectors are devices that are subject to wear with <br /> usage- However, FE Petro always recommends that the leak detector is in compliance with US EPA <br /> requirements. <br /> If the above results cannot be obtained, review the installation instructions to assure the leak detector was installed <br /> property. If everything has been done correctly and the results still cannot be obtained, contact the factory. <br /> 20. Fill out the warranty registration form completely and return to the factory immediately after completing the <br /> installation of the leak detectors. <br /> r.s ,. <br /> STP-MLD Vapor ?�J <br /> Tube connected to <br /> tank port �— <br /> ll <br /> G � J <br /> --t STP-MLD <br /> Figure 2 <br /> 6 <br />
