Returning Parts for Repair

If a Nivocompact FTC 831 cannot be repaired and needs to be sent back to
Endress+Hauser, then please note the following:
Remove all material residue attached to the probe.
This is especially important as the material may be of a dangerous nature
e.g. corrosive, poisonous, carcinogenic, radioactive etc.
Please return parts only after they have been thoroughly cleaned of
dangerous materials. Check in particular scratches and the possibility of
diffusion through plastic material.
When returning the probe, please state exactly the material in which it was
used and its characteristics.
A brief description of the error will also help us to diagnose the reason for it
and at the same time lower your costs.
Thank you for your cooperation.
