TUBE REPLACING
1)
Through the command OUPUT TUNE, move the sliding plane with fingers until the upper
end position (threshold bars completely exctracted)..
2)
Disconnect the mains voltage from equipment.
3)
Verify that the tube that must be replaced is cold sufficiently to avoid very serious burns.
5)
Verify that all internal tensions are decreased to 0 V, eventually short circuit by a switch
hook.
6)
Open the hinged front panel unscrewing the relative screws (FIG. 16).
7)
Unscrew the fixing screws of the internal panel of the RF cavity.
8)
Loosen the plate ring and raise it until the top position and then fix it in this position.
9)
Remove the high tension block from the top part of the tube.
10)
Remove the tube from its socket, exerting a perpendicular traction from the base (upwards)
and contemporary turn the tube to right and left side to reduce the frictions.
11)
To remount the tube executed the same operations from point 6) of the 3.3. paragraph “Tube
mounting”.

AIR FILTER REPLACING
1)
It isn’t necessary to switch off the equipment.
2) Open the rear grid of the air filter (
) unscrewing the relative fixing screws.
3)
Replace the air filter (felt), cleaning very accurately the internal part. Close the rear grid of the
air filter with its screws
