Electrode replacement
The electrode of the plasma generator has to be replaced in certain intervals depending on the
application.
The electrode replacement cycle of approximately 1000 hours was determined by relyon plasma in
standardized tests. Deviations are possible depending on the application.
To replace the electrode, carry out the following steps:
1. Switch of the device and wait until the plasma generator is cooled down.
2. Unscrew the nozzle (2) together with the coupling nut (1) (right-hand thread).
Caution: by removing the nozzle, the ceramic bushing (4) and the spacer may fall out of the
generator housing (5)!
3. Unscrew the electrode with O-ring (3) (right-hand thread) with a hex key AF 2,5 mm.
4. Pull the electrode with O-ring (3) out of the helix by hand.
5. Insert the new electrode with O-ring (3) with a rotary movement into the helix and fasten it with a
torque-limiting wrench (tightening torque 1 Nm).
6. If necessary, mount first the spacer (plastic) and then the ceramic bush (4) into the generator
housing (5).
Caution: Ensure the correct order for reassembly!
7. Screw the nozzle (2) together with the coupling nut (1) on to the generator housing (5) and
tighten them hand-tight.
8. The electrode is now replaced.
