1.
Check the electrodes for wear and
contamination.
2.
Clean the electrodes with a small
brush (not with a wire brush) or sand-
paper.
!
Please note
Wire mesh:
Do not damage.
3.
Check the electrode gaps. If the gaps
are not as specified or the electrodes
are damaged, replace and align the
electrodes together with new gas-
kets. Tighten the screws of the elec-
trodes. Torque: 2.0 Nm
Cleaning the heating surfaces
!
Please note
Do not damage the surfaces of
the heat exchanger that come
into contact with hot gas. This can
lead to corrosion damage.
Never use brushes to clean the
heat exchanger.
Brushing can cause deposits to
become lodged in the gaps
between the coils.
Note
Discolouration on the heat exchanger
surface is a normal sign of use. It has no
bearing on the function and service life
of the heat exchanger.
The use of chemical cleaning agents is
not required.
