Dispenser <br />sumps and dispenser <br />pans are installed just <br />beneath the above ground fuel dispensing units. Dispenser sumps <br />are non -corrosive, chemically compatible and structurally suitable for <br />underground burial applications. <br />1.1 General Information <br />This product manual contains useful information about all models of <br />dispenser sumps and pans. It is recommended that this manual be <br />read prior to specifying and installing under dispenser containers. <br />The installation practices shall comply with the installation <br />instructions contained within this product manual in order for the <br />product warranty to be valid. <br />1.2 Independent Testing <br />All OPW-FCS dispenser sumps and dispenser pans are listed with <br />Underwriters Laboratories, Inc. (UL'). The dispenser sump / pan <br />frames were tested to UL's "Standard Testing Procedure for <br />Underground Dispenser Sumps and Tank Sumps " and are UL <br />Listed. These tests verified the frame's ability to withstand a lateral <br />impact from all sides and permit proper activation of a shear valve <br />in the event of a knockover. The integrity of the sump itself was <br />conducted in accordance with UL's "Standard Testing Procedure for <br />Underground Dispenser Sumps and Tank Sumps" and is UL Listed <br />This test program tested the sump's fluid compatibility as well as its <br />ambient and low temperature physical properties. <br />1.3 Liquid Tightness <br />Dispenser sumps are open at the top and are sheltered from the <br />weather by the dispenser housing. Most dispenser sumps and <br />dispenser pans provide a T' vertical lip above the surface of the <br />island to prevent any surface run-off from entering the container. All <br />pipe and conduit entries are required to be sealed with flexible entry <br />boots. <br />1.4 Chemical Compatibility <br />All dispenser sumps and dispenser pans are made of either <br />fiberglass or polyethylene plastic material, both of which are <br />chemically inert and have a long history of underground burial <br />applications. Polyethylene and fiberglass have been used in <br />storage containers designed for containment of a long list of <br />chemical solvents. hydrocarbon and alcohol based fuels. All seals <br />are made of a specially formulated compound which has been <br />independently tested to insure its compatibility with a wide <br />
