This device is designed to cut the fuel flow down to a trickle <br />when it senses a leak or pressure drop in the product line. <br />There are several reasons for this device to trip: <br />1. A customer can hold the nozzle open before turning on the <br />pump, thus tripping it. <br />2. In cold weather, the product can contract while the station <br />is closed at night. <br />3. The device could be defective. <br />4. The device is sensing a leak. <br />WHAT TO DO <br />If the leak detector trips, you can reset it by simply turning on <br />one of the gas dispensers of that product type and letting it run <br />for a minimum of 30 seconds without dispensing fuel from that <br />nozzle or any other of that product type. This pressurizes the <br />line and resets the detector. <br />If the leak detector continues to trip or starts to trip every <br />morning, CALL THE MAINTENANCE DEPARTMENT 800-924-3273. <br />If you cannot get the detector to reset or it trips more than <br />once, call the Maintenance Department and shut the product down <br />that is giving the problem. <br />" <br />NOTE: You do not have to shut the whole gas island down, just the <br />product type that is giving you trouble. <br />b) LEAK SENSOR II - In the backroom of the store is a monitor box <br />that says Leak Sensor II. <br />This device monitors the cavity between the primary and secondary <br />fuel tanks and trench liner for gasoline or water. <br />These units have a set of alarm lights, a power light, and an <br />audible alarm to inform the personnel in the store if anything is <br />wrong. This unit must be checked daily to make sure the power <br />light is on and there have been no alarms. <br />If an alarm light comes on, but no audible alarm is heard, the <br />unit is detecting water somewhere in the secondary containment <br />and must be called in to Maintenance to be checked and reset. <br />If an alarm light comes on and an audible alarm is heard the <br />unit is detecting gasoline somewhere in the secondary containment <br />and must be called into Maintenance to repair and reset. The <br />audible alarm can be turned off by pushing the button or the <br />silent switch, but the red light will remain on. <br />You do not have to shut down the gas island if this unit trips <br />but you must inform Maintenance when any of the alarm lights or <br />' <br />audible alarms trip. <br />3 <br />
