2.6 Foreseeable improper use
Misuse of the product invalidates all warranty and liability claims. Any use that is counter to the purpose
of the product, whether intentional or unintentional, is regarded as misuse, in particular:
● Pumping of corrosive media
● Pumping explosive media
● Pumping radioactive or volatile media
● Pumping of gases that introduce an ignition source to the suction chamber
● Pumping of gases that contain impurities such as particles, dust, or condensate
● Pumping of fluids
● Pumping FPM-solubilizing media
● Pumping vapors from combustible liquids
● Pumping pressurized media (> atmospheric pressure)
● Pumping media that can condense or cause adhering deposits to form in the suction chamber
● Use of the vacuum pump outside the specified area of application
● Using the vacuum pump below ground
● Using the vacuum pump to generate pressure
● Using the vacuum pump in systems in which sporadic loads and vibrations or periodic forces act
on the unit
● Using the vacuum pump in strong electrical, magnetic, or electromagnetic fields
● Connection to vacuum pumps or equipment which are not suitable for this purpose according to
their operating instructions
● Connection to devices with exposed live parts
● Connecting to sockets without earthing contact
1)
at an installation location above 1000 meters above sea level, there is a risk of insufficient cooling. If necessa-
ry, take measures according to Directive DIN EN 61010.
