module.
Fig. 04: Unscrew the 2 screws that fix the
module to the wall and extract it horizontally.
Fig. 05: Gently unscrew the tubes, using
the green plastic base. If you have trouble,
first pull off the outer mesh.
Fig. 06: Pull off the outer mesh from the
tube if you have not already done so in the
previous point.
Clean the glass using a damp cloth.
If the operation is difficult
to perform, pull slightly the
earthing spring so that it is not
in contact with the surface of
the tube.
If this is difficult to do, turn the
mesh around the glass while
pulling to remove it.
Check that the tube is in good conditions: there must not be any cracks or other damage;
otherwise it must be replaced. As soon as you notice a whitish layer on the perforated
metal plate inside the glass it means that the ionising tube needs replacing.
The tubes must usually be replaced within 18 months of use.
