Cleaning (customer) Cleaning and maintenance
Clean the upper section of the precipitator
Remove the deposits in the upper section of the pre-
cipitator (above the sliding rake) using the poker, and
allow it to fall down.

Clean the flushing air opening
Vacuum out the opening for the electrode flushing air
on the isolator on the inside of the precipitator. Also
vacuum out the electrode holder or clean with a soft
cloth.

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 the electrode holder with a soft cloth.
Fig. 2-58: Electrode holder
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 electrode must be in the centre of the precipitator
so that the flue gas can be optimally cleaned.
Therefore, check the clearance of the electrodes to the
inner walls.

If the distance is uneven, check the electrodes.
May have been bent during cleaning.
