When opening the visual level indicator, bear in mind that the fluids and gases it contains could
be hazardous to health. It is imperative that you comply with the safety data sheets for the
process liquids and gases used.

Falling parts (screws, floats, etc.) may create impact sparks and lead to an explosion in
potentially explosive atmospheres. Make sure that there isn’t a potentially explosive atmosphere
and that no parts are falling when working on the visual level indicator.
