Return
The following procedures must be carried out before a flowmeter requiring repair or calibration, for
example, is returned to Endress+Hauser:
• Always enclose a duly completed "Declaration of Contamination" form. Only then can
Endress+Hauser transport, examine and repair a returned device.
• Enclose special handling instructions if necessary, for example a safety data sheet as per EN
91/155/EEC.
• Remove all residues. Pay special attention to the grooves for seals and crevices which could con-
tain residues. This is particularly important if the substance is hazardous to health, e.g. flammable,
toxic, caustic, carcinogenic, etc.
With Promass A and Promass M the threaded process connections must first be removed from the
sensor and then cleaned.
Note!
You will find a
preprinted
"Declaration of Contamination" form at the back of this manual.
Warning!
• Do not return a measuring device if you are not absolutely certain that all traces of hazardous sub-
stances have been removed, e.g. substances which have penetrated crevices or diffused through
plastic.
• Costs incurred for waste disposal and injury (burns, etc.) due to inadequate cleaning will be
charged to the owner-operator.
