When should I change the element?

How do I fit it?
Stop the machine and let the pressure out of the circuit. Open the filter housing, take out the old element and clean the bowl. Fit the new element with its new O rings lightly oiled, close the housing to the maker's torque, then run the machine and check for leaks.
