MP Filtri UFM Series, Use & Maintenance Manual

Page: 126 / 136

6.5 Normal and scheduled maintenance
The UFM919 does not require particular maintenance interventions, it is in any case a good rule to check the perfect condition
of the suction and discharge hoses before each use. Check that the filter element is correctly installed and that the filter cover is
tightly screwed on.
Periodically check the tightness of the hydraulic connections and if the electrical cable ends in the motor terminal box are tight. Also
check the cleanliness of the "Y" shaped filter for any accumulated macro impurities, so as to preserve the filter element (CU4006).
Check the expiration date of the particle counter calibration certificate.
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
- Versions with electric/visual differential pressure indicator for blockage
UFM919TA3020P01 - UFM919TA3021P01
The conditions related to the blockage of the filter element are ensured by an electric indicator (Fig. 20) mounted on the head of
the LMP430 filter. When the differential pressure of 3 bar is reached, the electric signal switches off the machine and turns on the
light on the electrical panel. Replace the filter element.
All models are equipped with a pressure gauge (Fig. 21) with 10 bar full scale to measure the circuit pressure.
For signalling the clogged filter, refer to the differential pressure indicators.
The LMP430 filter is equipped with a bypass valve with a response pressure set at 3.5 bar.
To keep the efficiency of the particle counter high, it is advisable to send it once a year to our headquarters for
inspection, monitoring, testing on the test bench and issuing a new calibration certificate.
CAUTION
!
It is recommended to never exceed the response pressure of the bypass valve (3.5 bar).
