6.5.1 Oil leaks
Oil leaks can form on the joints of the hoses and on fittings if any connections or screws are loosened, in which case we recom-
mend checking the correct tightness.
If the operations described above are not able to solve the problem, contact the manufacturer.
6.6 Filter clogging
The conditions relating to the clogging of the filter element are guaranteed by a pressure gauge (Fig. 4) mounted on the head of
the MPH250 filter. When the pressure reaches 1.75 bar, replace the filter element and at the same time clean the "Y" shaped filter
in the suction line.
The MPH filter is equipped with a bypass valve with a response pressure set at 3 bar.

CAUTION
!
It is recommended to never exceed the response pressure of the bypass valve (2.5 bar).
6.6.1 Replacing the filter element
Before proceeding with the replacement of the filter element, make sure that the oil temperature is lower than +40/45° C.
Replace the filter element whenever necessary, i.e. whenever the gauge indicates that the filter is clogged (1.75 bar) or when
different fluids must be filtered.
The filtration of the filter element takes place from inside to outside, the residual oil in the filter body is normally clean. The oil must
be emptied only when different fluids must be filtered using the drain valve (Fig. 5) installed at the base of the filter body.
