Residual risks
The machine is built to the state of the art and in conformity with recognized safety stan-
dards. The following residual risks exist and should be kept in mind when operating the
machinery. Residual risks associated with specific phases of the service life of the system
are detailed in the corresponding chapters of these instructions.
The system may only be operated in good condition.
When working on live electrical parts, there is the risk of death, serious injury and
damage to equipment.
Switch off the machinery/system in the event of a fault in the power supply.
If work is necessary on voltage-carrying parts, the system must be disconnected from
the mains with the master switch. The master switch must be secured against accidental
activation (e.g. with a personal padlock).
Only professional electricians should perform work on electrical systems and operating
media.
Never remove any covers. The door of the control cabinet must be kept closed at all
times.
High flue gas concentrations in the air can result in unconsciousness and the risk of suf-
focation.
Take the following precautions before working on the flue gas system:
Ensure that the combustion system has been stopped and that no flue gases are coming
from the combustion system.
Ensure that the flue gas system has cooled down.
Ensure adequate ventilation.
Ensure that the combustion system is secured against unauthorised operation.
Operation without a connection to the flue gas pipes is prohibited.
Always close cleaning openings after cleaning.
There is a risk of falling when climbing on the system. Never climb on the system.
Do not use system parts for climbing. Wear fall-protection equipment during mainte-
nance work at high elevations.
During work at heights of more than 1.8 m (6'), use safe climbing equipment or work
platforms.
