Return

The following procedures must be carried out before a transmitter is sent to Endress+Hauser e.g. for repair or
calibration:
• Remove all residue which may be present. Pay special attention to the gasket grooves and crevices where
fluid may be present. This is especially important if the fluid is dangerous to health, e.g. corrosive,
poisonous, carcinogenic, radioactive, etc.
• Always enclose a duly completed "Declaration of contamination" form (a copy of the "Declaration of
contamination is included at the end of this operating manual). 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.
Additionally specify:
• An exact description of the application.
• The chemical and physical characteristics of the product.
• A short description of the error that occurred (specify error code if possible)
• Operating time of the device.
