6.2.2 Filter
•
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!
6.3 Adjusting the setting scale
If the adjustment knob is removed, this setting is lost. A new
setting can be achieved using a pressure gauge.

tap)
