Maintenance

4.1

General information

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.

Additional maintenance work for systems with water back purging

Check the connection piece for the extraction hose on the swirl chamber for deposits. 

4.2

Replacing the water filter

The water filter must be checked for contamination during regular maintenance of the 
FWE200DH. Replace the filter when there is visible contamination (

see “Spare parts / con-

sumables”, page 27

).

Replacing the water filter
Checking the spray pattern

NOTE:

Observe the relevant safety regulations as well as safety notices (

see ”Responsibility of 

user”, page 6

) during all work. 

NOTE:

Do not damage any device parts during maintenance work.

Switch off water supply during maintenance work

Do not interrupt the purge gas supply.
