• Replace defective seals only with original seals from Endress+Hauser.
• If threads are defective, the measuring device must be repaired.
• Threads (e.g. of the electronics compartment cover and connection compartment cover)
must be lubricated if an abrasion-proof dry lubricant is not available. Use acid-free, non-
hardening lubricant.
• If, during alteration, spacing is reduced or the dielectric strength of the measuring device
cannot be guaranteed, perform a test on completion of the work (e.g. high-voltage test in
accordance with the manufacturer' s instructions).
• Service connector:
• Do not connect in potentially explosive atmospheres.
• Only connect to Endress+Hauser service devices.
• Observe the instructions for transporting and returning the device outlined in the Operating
Instructions.
