2.4 Intended use
The machine is suitable for conveying the following media:
• Air:
The extracted air may contain water vapour, but no water or other liquids. For water vapour compati-
bility, see Info I 200
• all non-explosive, non-combustible, non-aggressive and non-poisonous damp gases and gas-air
mixtures
The machine must only be operated in such areas as are described in the operating instructions:
Ø Only operate the machine in technically perfect condition
Ø The machine must only be operated at an ambient temperature and inlet temperature of between 5 and
40 °C
Please contact us for temperatures outside this range.
Ø The permissible back pressure may not be exceeded
Maximum permissible back pressure: +100mbar
Any use extending beyond this use is seen as not in accordance with the intended use.
The intended use also includes the compliance with the operating data and operating agents specified in the
operating instructions, the listed maintenance works, as well as the details in the documentation issued by
the manufacturers of components and attachments.
If used under critical conditions and/or in case of any doubts, please contact the manufacturer. Non-obser-
vance can cause machine failures.
2.5 Inadmissible operating modes
• Extracting, conveying and compressing explosive, inflammable, aggressive or poisonous media, e.g. dust
as per ATEX zone 20-22, solvents as well as gaseous oxygen and other oxidising agents
• Erection and operation in potentially explosive environment (explosive gas/vapour/mist-air mixtures or
dust-air mixtures or hybrid mixtures of air and flammable substances)
• Using the machine in non-commercial plants unless the necessary precautions and protective measures
are taken in the plant
• Continuous operation outside the intake pressure ranges (see also chapter4.4)
• Operation of the machine when it is only partially assembled
• Using the machine in areas with ionising radiation
• Back pressures on the outlet side of more than +100 mbar
• Modifications to machine and accessories
• Operation by not or not sufficiently qualified personnel
2.6 Personnel qualification and training
All works are only allowed to be done by qualified and trained specialist personnel of legal age. Unauthori-
sed persons are not allowed to stay within the area of the vacuum pump and must be kept away from the
danger zone by suitable measures.
Ø Ensure that people entrusted with working on the machine have read and understood these operating
instructions before starting work, particularly the safety instructions for installation, commissioning, main-
tenance and inspection work
Ø Responsibilities, competences and monitoring of personnel must be regulated by the operating company.
