environmental from escaping, or dispose of these according to the applicable regulations.
► Avoid contact with process gases that are harmful to health and if required, wear personal protec-
tive clothing.
► Check the media compatibility of parts carrying media.
► Observe all applicable safety and accident prevention regulations.
► Check that all safety measures are observed at regular intervals.
► Do not expose body parts to the vacuum.
► Never disconnect plug connections during operation.
► Never fill or operate the unit with cleaning agents or cleaning agent residues.
► Do not carry out your own conversions or modifications on the unit.
► Observe the unit protection degree prior to installation or operation in other environments.
► Provide suitable touch protection, if the surface temperature exceeds 70°C.
► Keep lines and cables away from hot surfaces.
► Before returning the vacuum pump, observe the notes in the chapter Service solutions.

2.6 Foreseeable improper use
Improper use 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 improper use; in particular:
● Pumping of corrosive media with vacuum pumps in standard version
● Pumping of explosive media
● Pumping radioactive or volatile media
● 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
1)
at an installation location higher than 1000 meters above sea level, there is a risk of insufficient cooling. If nec-
essary, take measures according to Directive DIN EN 61010.
