WARNING
For persistent encrustations onto the filter net or if the pressure
difference between the two manometers remains above 1 bar
after cleaning the filter, replace the filter with a new one.
We recommend replacing stainless steel net cartridges at least
every 48 months. The filter bowl must be replaced with a new
one at least every 5 years.
Follow the local regulation in force when disposing cartridges
and bowls.
