Checking the System System Checkout <br /> Purge Air from Lines <br /> Failure to purge air from the lines can cause the system to malfunction. <br /> 1. Purge air from the product lines as follows: <br /> a. Tum on the dispenser farthest from the tank. <br /> b. Wait approximately 2 minutes. <br /> c. Pump 10 to 20 gallons,or until no more air is present. <br /> d. If no shutoff valve is installed in product line,repeat steps a through c for <br /> each dispenser,working from the farthest from the tank to the closest to the <br /> tank. <br /> If a shutoff valve is installed in product pipeline and used to prevent <br /> drainage,you only need to pump fuel from the farthest dispenser. <br /> AWARNING <br /> Product spillage could create serious environmental and safety <br /> hazards. <br /> Fire, explosion, or ground contamination could occur. <br /> 1. Carefully check all fittings for leaks. If a leak is detected, correct <br /> condition immediately. Repair product pipeline or component <br /> using approved containers and procedures that will prevent <br /> product spillage. <br /> 2. Dispose of any spilled fuel properly. Used an approved suitable <br /> container for moving fuel and approved procedures for disposing <br /> of fuel. Dispose of fuel soaked materials properly and not into <br /> trash barrels that may be used by customers. <br /> 2. Carefully check all fittings and the functional element for leaks. <br /> 3. Verify that the functional element,strainer,and check valve threads into the pump <br /> are not leaking. <br /> Important The PLLD does not perform any leak test upstream from the check valve and will not <br /> detect assembly leaks there. <br /> 4. Tighten any leaking fittings until the leak is stopped.Be careful not to overtighten <br /> and strip the threads. <br /> 5. If the leak cannot be stopped,turn off power to the submersible and check the <br /> fitting for thread damage or improper sealing. <br /> 576013-902,Revision G 41 <br />
