Return
Before returning a device to Rockwell Automation, be sure to remove all fluid residue. This
is particularly important if the fluid is a health hazard, e.g. flammable, toxic, caustic,
carcinogenic, etc.
Do not return a measuring device if you are not absolutely
certain that all traces of hazardous substances have been
removed, e.g. substances which have penetrated crevices
or diffused through plastic.
