MAINTENANCE
PFE – CLEANING AND CHANGE OF PARTS (FIG.A)
To easily maintain the PFE, it is recommended to place it on the opposite side of the circuit breaker so
that it is positioned as shown.
Using the side screws (1), open the closing panel (2), remove the anti-spark filter (3) and wash it with an
air jet in the opposite direction to the suction flow or replace it if it is too dirty. Replace it in the seat by
inserting it into the appropriate guides.
Unscrew the locking knob (4) of the cartridge (5) and then pull it out. Wash it with a jet of air in the
opposite direction to the suction flow or, if it is too dirty, replace it. Then, carefully place it back in its seat
by tightening the clamp knob (4) down.
From the air outlet side, you can find the carbon filter panel (6), remove it and replace it with a new one.
Make sure all filters are positioned correctly, then place the locking panel (2) and fasten all the screws
that hold it in position (1).
ATTENTION:
All these operations must be done absolutely while the socket is disconnected from power supply.
