STRUCTIONS FOR REPLACEMENT OF THE OIL SEPARATOR ELEMENT
1. The operation must be undertaken with machine off and no
pressure in the oil separator tank.
2. Disconnect all the pipes from the connections positioned on
the closure flange of the separator tank, marking them so there
is no problem on re-assembly.
3. Loosen the screws (A) and remove the flange (B).
4. Extract the filtering element (D) together with the seals (C) and
(E).
5. Assemble the new seal (E) in the relative slot which has been
previously cleaned. Endure that a metallic insert has been
clipped to the seal in order to avoid the isolation of the filter
and the accumulation of static electricity. Otherwise there is a
risk of the separator filter catching fire.
6. Insert the new separator element correctly positioning it into
the relative slot.
7. Assemble the second seal (C) with the same precautions as
above.
8. Reassemble the flange (B) in the pre-assembly position.
9. Tighten the bolts, (A), with a tightening torque of 80 Nm.
10. Re-connect all the pipes to the respective fittings.
11. Start up the machine ensuring there is no leakage between the
cap and the tank.
12. Allow the machine to operate for 10-15 minutes with closed
cocks
13. Stop the machine with tank depressurized to 0 bar, re-check
the screw tightening (A).
