Veeder-Root Sensor Application Guide Servicing Discriminating Dispenser Pan and Containment Sump Sensors 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 TM 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 per- formed. 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 ColemanTM 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 per- formed. The recovery time will depend on how long sensor was exposed to the diesel fuel or kerosene. Biodiesel Blend Limitations Biodiesel blends that meet ASTM standards D6751 and D7467 are compatible with the respective sensors.
