Cleaning and maintenance
Do not damage or bend the electrode during
cleaning.

Clean flushing air opening
Vacuum out the opening for the electrode flushing air
on the isolator on the inside of the precipitator.
Fig. 2-23: Flushing air opening on the isolator
Do not clean the opening with compressed air,
because this will stir up the ash, which can end up
in the precipitator control system and cause damage.
Clean and inspect the electrode holder
Clean both electrode holders with a soft cloth.

Then inspect the status of the electrode holders.
The best way to do this is to check the electrode
holder manually, especially the area around the
flushing air openings. If cracks or small holes can be
"felt" there is damage. In this case, contact ETA
Customer Support.
Check the alignment of the electrodes
The electrodes must be in the centre of the precipitator
so that the flue gas can be optimally cleaned.
Therefore, check the clearance from the electrodes to
the inner walls.
Fig. 2-25: Electrode
If the clearance is uneven, check the electrodes.
They may have been bent during cleaning.
