For instruments with a hollow liquid level displacer, the displacer might retain process fluid or pressure. Personal injury
or property damage due to sudden release of pressure, contact with hazardous fluid, fire, or explosion can be caused by
puncturing, heating, or repairing a displacer that is retaining process pressure or fluid. This danger may not be readily
apparent when disassembling the sensor or removing the displacer. Before disassembling the sensor or removing the
displacer, observe the appropriate warnings provided in the sensor instruction manual.

Personal injury or property damage, caused by fire or explosion from the leakage of flammable or hazardous gas, can
result if a suitable conduit seal is not installed. For explosion‐proof applications, install the seal no more than 457 mm
(18 inches) from the instrument when required by the nameplate. For ATEX applications use the proper cable gland
certified to the required category. Equipement must be installed per local and national electric codes.
