6.2.2 Filter
•
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
CAUTION!
Do not forget to do a visual check of the ball valve.
Replace if it is dripping!
