8. Operaon
DANGER: EMISSION OF HAZARDOUS GAS
Danger as a result of rapid increase in pressure due to decomposion of pumped gases.
Uncontrolled emission of process gases by reacon products within the pump. The
pumping of reacve gases, vapours or gas mixtures is generally prohibited. The operator
is responsible for the assessment of the hazard potenal of the process media or
mixtures.
Dangers through escaping or eming transported hazardous gases, vapours or
substances. Process gases may escape from the exhaust and from leaks in the vacuum
system. The pumping of pyrophoric / radioacve / oxidizing gases or gas mixtures, as well
as the pumping of oxygen of more than atmospheric concentraon (21 %) is generally
prohibited. The operator is responsible for the assessment of the hazard potenal of the
process media or mixtures.
WARNING: EJECTION OF PARTS
Ejecon of parts by bursng of the vacuum system due to excessive pressure 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 throled.
Ejecon of parts by bursng of the vacuum system due to excessive pressure caused by
the pump running backwards aer it has been switched o under vacuum. Danger of
overpressure in the inlet lines and recipients as well as uncontrolled backward running of
rotors. In the event of a fault or during service, separate the vacuum pumps from the
vacuum container and connecng lines before the inlet by means of suitable valves.
CAUTION: EXTREME SUCTION
Pulling body parts and objects into the vacuum through open anges.Do not put the
vacuum pump into operaon with open anges. During installaon of the vacuum pump
rst mechanically connect the inlets and outlets, and only then make the electrical
connecons.
CAUTION: TRIP HAZARD
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
measures.
CAUTION: HOT SURFACES
Burns due to contact with hot surfaces. Burning of ngers, hands or arms on hot surfaces.
Handle the pump only when venlated and cooled down. Wear suitable protecve
equipment.
