2.4 Intended use
The machine is suitable for conveying the following media:
• All non-explosive, non-combustible, non-aggressive and non-poisonous, dry gases and gas-air
mixtures
The machine is permitted to be operated only in such areas that are described in these Operating
Instructions:
ØOnly operate the machine in technically perfect condition
ØThe 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
ØThe machine is only permitted to be operated within the speed range and frequency range that is speci-
fied on the data plate of the frequency converter
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 of explosive, inflammable, aggressive or poisonous media, e.g.
dust as per ATEX zone 20-22, solvents as well as gaseous oxygen and other oxidation agents, water
vapour, liquids or solids
• 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
• Operation of the machine when it is only partially assembled
• Operation without cover sheet
