2.6 Foreseeable improper use
Improper use of the product invalidates all warranty and liability claims. Improper use is any, even unin-
tended, use, which is contrary to the product purpose; and in particular:
● Pumping of corrosive media
● Pumping radioactive media
● Pumping of condensable vapors
● 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 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
● 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
● Use of accessories or spare parts not listed in these operating instructions
● Using the vacuum pump as a climbing aid
● Use of operating fluids other than those specified by Pfeiffer Vacuum
● Use of D1 or mineral oil as operating fluid with an oxygen concentration level of > 21 %
Mineral oils are combustible and ignite in high temperatures and when they come into contact with
pure oxygen. This oils oxidize heavily and thus lose their lubricating capacity.
