C Installation Guide Installation Procedure 40e • DO NOT wire submersible pumps to run continuously. Red Jacket line leak detectors will not perform leak tests on pumping systems that run continuously. ALL AIR MUST BE OUT OF THE SYSTEM FOR THE LEAK DETECTOR TO WORK PROPERLY. Before installing leak detector in the pump, fill the system with product by running the pump and delivering product from each dispenser (starting with the farthest from the pump and working to the pump) until all air is removed from system. Certain regulatory bodies require that leak detectors remain in the system after the lines have been installed. The lines may be purged of air by back -pressuring the lines with an inert gas, such as helium or nitrogen, to a pressure of 25 psi (172 kPa). This may be done at the impact valve under the dispenser. When this pressure has been reached, the leak detector will be in the open position, By turning on the pump and gradually bleeding the gas from the line through a valve at the impact valve of the farthest dispenser, the line may be purged of air. Installation Procedure e Disconnect power to the submersible pump and relieve pressure before installing or removing petroleum equipment. 1. Disconnect power to pump at the load center. Tag or lock out the breaker to avoid the pump being turned on accidentally. 2. Remove the two-inch plug from the top of the Standard pump (see Figure 1 for The Red Jacket leak detector installation ports). If the two-inch plug is found to be so tight that cannot be removed, the submersible should be removed from the tank and placed in a vise. Remove the functional element assembly next to the pipe plug. The plug should then come out readily if a large pipe wrench is used. Replace functional element assembly securely and replace the pump in the tank. (See Step 3 before replacing pump).
