General safety precautions when handling the product
► 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.
► Always ensure a secure connection to the earthed conductor (PE).
► Never disconnect plug connections during operation.
► Observe the above shutdown procedures.
► Keep lines and cables away from hot surfaces (> 70 °C).
► 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 class prior to installation or operation in other environments.
► Provide suitable touch protection, if the surface temperature exceeds 70 °C.
2.4 Safety precautions for vacuum pumps with magnetic coupling
The following safety instructions are only valid for the working with a drive system of a vacuum pump
with a magnetic coupling:
Safety precautions
► Keep a magnetic coupling away from people with pacemakers.
– Minimum distance:
2 m
► Avoid convergence of magnetic coupling components.
► Keep magnetized parts away from the magnetic coupling.
► Always keep a disassembled magnetic coupling away from computers, data carriers and other
electronic components.
– The magnetic coupling can influence operational reliability of electrical and electronic devices.

Limits of use of the product
2.6 Proper use
► Use the vacuum pump for vacuum generation only.
► When pumping media with an oxygen concentration level of ≥ 21 %, only use perfluorinated, syn-
thetic oils (F4, F5, A113) as operating fluid.
► Adhere to the installation, commissioning, operating, and maintenance instructions.
► Do not use any accessory parts other than those recommended by Pfeiffer Vacuum.
2.7 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 misuse, in particular:
● Pumping of corrosive media (exception: C version of the rotary vane vacuum pumps)
● 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 explosive media
