• The filter must be cleaned by reverse rinsing regularly,
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 to do a visual check of the ball valve.
Replace if it is dripping!
