Elektronic insert FEC 22

9 Repairs

Should the FEC 22 electronic insert need to be repaired by Endress+Hauser, please
send it with a note containing the following information:
• An exact description of the application for which it was used.
• The chemical and physical properties of the product measured.
• A short description of the fault.
Special precautions must be observed when sending the probe and its FEC 22 for
repair:
• Remove all traces of product. This is particularly important if the product can impair
health, i.e. corrosive, poisonous, carcinogenic, radioactive etc..
• If the last traces of dangerous products cannot be removed, e.g. product has
penetrated into fissures or diffused into plastic parts, we kindly ask you not to send
the probe for repair.
