This chapter only describes additional maintenance work to be carried out.
Maintenance work on the FWE200DH remains identical with the water back purge function
fitted and must continue to be carried out at the specified intervals. Details can be found in
the regular device Operating Instructions.
Before carrying out maintenance work, set the measuring system to “Maintenance” mode
(see FWE200DH Operating Instructions).
In addition, the on-site water supply must be switched off.
