6.1 Inspection
6.1.1 Pressure reducing valve (FK74CS/
FKN74CS only)
1. Close shut-off valve on outlet
2. Check outlet pressure using a pressure meter when
there is zero through-flow
• If the pressure is increasing slowly, the valve may
be dirty or defective. In this instance, carry out
servicing and cleaning (See 6.2 Maintenance)
3. Slowly open shut-off valve on outlet
6.1.2 Filter
• The filter must be cleaned by reverse rinsing at the
latest every 6 months! (According to EN 806-5.)
Producer recommendation at least every 2 months!
• Non-compliance can lead to the filter becoming
blocked This results in a drop in pressure and
decreased water flow
• The filter meshes are made of stainless steel. A red
coating as a consequence of rust from the pipelines
has no influence on function or the way the filter works
Do not forget the visual check of the ball valve.
Exchange the KF11SB filter bowl in case of drop
formation!
