Warning: For LP-Gas and other flammable product service applications, connect only to circuits and power sources classified and labeled Intrinsically Safe for Class 1, Division 1, Group C and D hazardous locations. Connection of non-intrinsically safe power could result in fire or explosion of flammable vapor which may be present.

Warning: Sensor not to be used as the primary means of determining high or low fuel condition. It must not be used in the absence of redundant systems in critical applications where there may be significant safety risk or financial exposure in the event of fuel overfill or fuel exhaustion condition. This sensor is not to be used for tank filling.
