Preparation
Before this maintenance, perform all steps for the
preceding maintenance intervals
Before this maintenance, all steps for the
preceding maintenance intervals must be
performed.
WARNING!
The following activities may only be performed by
qualified specialist personnel.
If you carry out these activities without the correspond-
ing specialist training, and above all without the
required experience, safe operation is no longer
guaranteed. The resulting defects and consequential
damage are excluded from the guarantee and
warranty.
Equally an incorrect performance of these activities
can lead to serious injuries.
End heating mode
End the boiler's heating mode with the On/Off switch in
the boiler overview window. The boiler performs an
ember burnout and then changes to the [Switched off]
operating mode. Then start de-ashing, so that the
boiler can perform a final de-ashing.
WARNING!
Switch off the electricity to the boiler via the mains
switch
Switch off the electricity to the boiler via the mains
switch. This prevents injuries caused by switching
the boiler on inadvertently.
DANGER!
Caution high voltage!
The electrode inside the precipitator can
still have residual voltage even after
switching off the power supply.
Therefore, switch off the boiler at the
mains switch and ensure that it cannot be switched
back on before starting work. Then establish
additional earthing between the electrode on the
inside and the housing of the precipitator.
