12. CONTROLS ON THE ELECTROSTATIC FILTER
Perform periodic checks to verify the status of its basic components, proceed to replace them in case of
breakage or perform preventive maintenance. Do the following:
- clean the ionisation wires
- replace the ionisation wires of the electrostatic cell.
12.1
CLEANING THE IONISATION WIRES
Some types of pollutants cause slight encrustation or oxidation of ionisation wires.
To avoid this it is necessary:
- to clean the wires with a cloth soaked in alcohol.
- to remove the oxide layer deposited on the wire with a very fine-grained synthetic abrasive pad (SCOTCH-
BRITE).
Do so every time there is a rough layer of oxide or deposits on the surface of the wire.
12.2.
REPLACING ELECTROSTATIC CELL IONISATION WIRES
Ionisation wires are subject to wear due to the high voltage they are subjected to.
To avoid unexpected breakage, it is a good rule to replace all ionisation wires once a year, proceeding as
follows:
a) if an ionisation wire breaks, remove all pieces of wire present in the cell and remove the springs that keep
the wire taut
b) hook the spring to the eyelet of the wire as shown in the drawing

c) take the ionisation wire with curved nose pliers
as shown in the figure below
d) hook the end of the spring with the eyelet open
to the wire-tensioning rod of the electrostatic cell
e) keeping the ionisation wire taut with the other
hand, fasten it to the other wire-tensioning rod using
the curved nose pliers
