purpose of the product, whether intentional or unintentional, is regarded as misuse, in particular:
● Pumping of corrosive media
● Pumping radioactive 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 explosive media
● Pumping of media with a propensity to sublimation
● Pumping of fluids
● Use of the vacuum pump in potentially explosive atmospheres
● Use of the vacuum pump outside the specified area of application
● Use for pressure generation
● Use in strong electrical, magnetic, or electromagnetic fields
