8 Servicing Discriminating Dispenser Pan and Containment Sump Sensors This procedure applies to Discriminating Dispenser Pan and Containment Sump Sensors having Form Numbers , -322, -350, -352, -360, -361, and When replacing Dispenser Filters or servicing Dispensers The sensor should be removed from the dispenser pan before replacing the filters. All fuel must be cleaned up in the dispenser pan prior to reinstalling the sensor. If the sensor is exposed to fuel during the filter replacement, the sensor may go into a fuel alarm. If this occurs the sensor must be removed from the dispenser pan and the sensor allowed to dry in a well ventilated area for up to 7 days. The recovery time will depend on how long the sensor was exposed to the fuel. If the sensor has been exposed to diesel fuel or kerosene, it will be necessary to first soak the sensor in Coleman fuel for 30 minutes and then set aside to dry in a well ventilated area for up to 7 days. It is advisable that the affected sensor be replaced and taken to a location where the soaking and recovery process can be safely performed. The recovery time will depend on how long sensor was exposed to the diesel fuel or kerosene. When Sensor is in alarm due to a spill or leak in the containment area Remove the sensor from the containment area upon arrival at the location. Dry off the sensor and allow it to recover in a well ventilated area for up to 7 days. The recovery time will depend on how long the sensor was exposed to the fuel. The sensor can be reinstalled in the containment area once the sensor has recovered and the source of the leak repaired. The containment area must be free of fuel. If the sensor has been exposed to diesel fuel or kerosene, it will be necessary to first soak the sensor in Coleman fuel for 30 minutes and then set aside to dry in a well ventilated area for up to 7 days. It is advisable that the affected sensor be replaced and taken to a location where the soaking and recovery process can be safely performed. The recovery time will depend on how long sensor was exposed to the diesel fuel or kerosene. 3

9 Non-Discriminating Solid-State Dispenser Pan and Containment Sump Sensors The appropriate sensor can be installed in a Dispenser Pan (Form Number ) or in a Containment Sump ( ) and will detect the presence of a liquid. Ultrasonic liquid level sensing technology means no moving parts and a lower temperature operating limit. Fuel alarm is triggered when liquid reaches a nominal height of 1-inch on both Dispenser Pan and Containment Sump sensors. An open sensor triggers a Sensor Out alarm. Operating temperature range: -40 to +70 C. Storage temperature range: -40 to +70 C. Standard cable length: 12 feet. Dispenser Pan Sensor dimensions: 11.6 high, 2.2 diameter.

11 Mag Sump Sensor The Mag Sump Sensor detects the presence and amount of water and/or fuel in the containment sump or dispenser pan. Using proven magnetostrictive technology to detect the presence of hydrocarbons and water, the station (where allowed) remains in operation when water alone is detected. An alarm is also generated if the sensor has been moved from its proper position at the bottom of the sump or pan. Fuel Alarm - triggered when fuel reaches approximately 1.5 in height. Water Warning Alarm - triggered when water level reaches approximately 1.7 in height (or other programmable height). Installation Alarm - triggered when sensor is moved from proper operating position. Comm Alarm - triggered when there is no communication with the sensor. Operating temperature range: -40 to +60 C.

18 Hydrostatic Reservoir Sensor The Hydrostatic Reservoir Sensor accurately detects fluid level change in the reservoir and interstice of a doublewall storage tank. This sensor is available in a dual-point or single-point configuration. The Dual-Point version is ideal for high groundwater areas, and can differentiate between a high level alarm condition and a low level alarm condition. If an inner-wall leak occurs, the brine seeps into the tank triggering a low level alarm, if an outer wall leak occurs, fluid seeps into the interstice triggering a high level alarm. The Single-Point version can be used in low groundwater locations. If an inner-wall leak occurs, the brine seeps into the tank triggering a low level alarm, or if the outer wall leaks, the brine seeps out of the tank interstice triggering a low level alarm. Dual-Point Version - Leak in inner wall triggers a low level alarm - Leak in outer wall triggers a high level alarm in high groundwater areas or a low level alarm in low groundwater areas. An open sensor triggers a Sensor Out alarm. Single-Point Version Leak in inner or outer wall triggers a Fuel alarm in low groundwater areas. An open sensor triggers a Sensor Out alarm.
