� 11 <br />WARNING <br />This equipment is usual punted underground. Personnel king on this equipment are in <br />danger from moving vehicles entering the work area due to the service personnel's reduced <br />visibility. ALWAYS secure the work area by parking the service truck, and using all other means <br />available, so as to prevent vehicles from driving over or near the work area. <br />I_`,___ CAUTION <br />Thermal expansion can cause pressure to build up in the product lines. FE Petro, Inc. check <br />valves have a built-in relief valve to release this excess line pressure back to the tank. Do not use <br />an additional check valve unless it has the capability to relieve excess pressure, as this could <br />result in a buildup of abnormal pressure in the lines, causing a pipe or joint in the supply line <br />piping to burst, and release of fuel into the environment. <br />NOTE <br />Some underground storage tanks are ballasted with water during construction. It is best to <br />remove the extractable portion of the pump if there is water in the tank and cover the manifold <br />opening to prevent foreign material from getting into the tank. DO NOT use the submersible pump <br />to remove water from the tank. The pump is designed for use with petroleum products only, and <br />pumping other fluids will seriously damage the unit. We do not recommend immersing the pump <br />in water, but if this does happen immediately fill the tank with motor fuel after the water is removed <br />from the tank. Severe corrosion takes place very quickly if the unit has been submerged in water <br />and is then exposed to air. <br />Installer: This instruction booklet MUST be left with the owner of the service station at which the <br />equipment is being installed. <br />Station Owner: Retain these instructions for future use and provide them to persons servicing or <br />removing this equipment. <br />3 <br />
