WARNING
Danger of poisoning due to toxic process media escaping from the exhaust pipe
During operation with no exhaust line, the vacuum pump allows exhaust gases and vapors to escape
freely into the air. There is a risk of injury and fatality due to poisoning in processes with toxic process
media.
► Observe the pertinent regulations for handling toxic process media.
► Safely purge toxic process media via an exhaust line.
► Use appropriate filter equipment to separate toxic process media.
WARNING
Explosion hazard from reactive, potentially explosive or other hazardous gas/air mixtures
Uncontrolled inlet of gas at the gas ballast valve leads to sparks generated mechanically following
diaphragm rupture, hot surfaces or to potentially explosive gas/air mixtures in the vacuum system
caused by static electricity.
► If necessary, use inert gas for supplying the flushing gas in order to avoid a potential ignition.
WARNING
Risk of poisoning due to toxic process gases escaping
For intake pressures > 500 hPa, process gas may escape from the open gas ballast valve. There is a
risk of injury and fatality due to poisoning in processes with toxic process media.
► If necessary, use inert gas to avoid potential contamination.
► If necessary, use an extraction line.
CAUTION
Danger of burns on hot surfaces
Depending on the operating and ambient conditions, the surface temperature of the vacuum pump
can increase to above 70 °C. If access to the vacuum pump is unrestricted, there is a danger of burns
due to contact with hot surfaces.
► Install suitable touch protection if the vacuum pump is unrestrictedly accessible.
► Allow the vacuum pump to cool down before carrying out any work.
► Contact Pfeiffer Vacuum for suitable touch protection in system solutions.
CAUTION
Danger of injury from moving parts
After a power failure or a standstill as a result of overheating, the motor restarts automatically. There
is a risk of injury to fingers and hands if they enter the operating range of rotating parts.
► Safely disconnect motor from the mains.
► Secure the motor against reactivation.
► Dismantle the vacuum pump for inspection, away from the system if necessary.
CAUTION
Danger of burns on hot surfaces
In the event of a fault, the surface temperature of the vacuum pump can increase to above 105 °C.
► Allow the vacuum pump to cool down before carrying out any work.
► Wear personal protective equipment if necessary.
