DANGER: EMISSION OF HAZARDOUS GAS
Danger as a result of rapid increase in pressure due to decomposion of pumped gases.
Uncontrolled emission of process gases by reacon products within the pump. The
pumping of reacve gases, vapours or gas mixtures is generally prohibited. The operator
is responsible for the assessment of the hazard potenal of the process media or
mixtures.
Dangers through escaping or eming transported hazardous gases, vapours or
substances. Process gases may escape from the exhaust and from leaks in the vacuum
system. The pumping of pyrophoric / radioacve / oxidizing gases or gas mixtures, as well
as the pumping of oxygen of more than atmospheric concentraon (21 %) is generally
prohibited. The operator is responsible for the assessment of the hazard potenal of the
process media or mixtures.
WARNING: EJECTION OF PARTS
Ejecon of parts by bursng 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 throled.
Ejecon of parts by bursng of the vacuum system due to excessive pressure caused by
the pump running backwards aer 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 connecng 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 operaon with open anges. During installaon of the vacuum pump
rst mechanically connect the inlets and outlets, and only then make the electrical
connecons.
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 venlated and cooled down. Wear suitable protecve
equipment.
