4 Operation
Danger as a result of sharp increase in pressure due to decomposition of
pumped gases. Uncontrolled emission of process gases by reaction prod-
ucts within the pump.
The pumping of reactive gases, vapours or gas mixtures is generally pro-
hibited. The operator is responsible for the assessment of the hazard
potential of the process media or mixtures.
Dangers through escaping or emitting transported hazardous gases,
vapours or substances. Process gases may escape from the exhaust and
from leaks in the vacuum system.
The transport of poisonous / explosive / flammable / pyrophoric / radioac-
tive / oxidizing / corrosive gases or gas mixtures, as well as oxygen of
more than atmospheric concentration (21 %) is generally prohibited. The
operator is responsible for the assessment of the hazard potential of the
process media or mixtures.
Ejection of parts by bursting of the vacuum system due to excessive pres-
sure caused by clogged or constricted exhaust.
Pressure build-up in the vacuum system or exhaust pipes.
Do not operate the vacuum system with the outlet closed or throttled.
Ejection of parts by bursting of the vacuum system due to excessive pres-
sure caused by the pump running backwards after it has been switched off
under vacuum.
Danger of overpressure in the inlet lines and recipients as well as uncon-
trolled backward running of rotors.
In the event of a fault or during service, separate the vacuum pumps from
the vacuum container and connecting lines before the inlet by means of
suitable valves.
Pulling into the vacuum system.
Pulling body parts and objects into the vacuum through open flanges.
Do not put the vacuum pump into operation with open flanges. During
installation of the vacuum pump first mechanically connect the inlets and
outlets, and only then make the electrical connections.
Hazard of slipping, tripping or falling due to oil leakage from the pump.
During transport or depending on the work process, oil may escape from
the vacuum pump. Risk of falling on oil spills!
Check vacuum pump regularly for oil leaks. Take appropriate safety meas-
ures!
Burns due to contact with hot surfaces.
Burning of fingers, hands or arms on hot surfaces.Handle the pump only
when ventilated and cooled down. Wear suitable protective equipment.
