Infringement of conformity due to modifications to the product
The Declaration of Conformity from the manufacturer is no longer valid if the operator
changes the original product or installs additional equipment.
● Following the installation into a system, the operator is required to check and re-evalu-
ate the conformity of the overall system in the context of the relevant European Direc-
tives, before commissioning that system.
General safety precautions
► Do not expose body parts to the vacuum.
► Observe the safety and accident prevention regulations, if necessary wear personal protective
equipment.
► Check all safety measures at regular intervals.
► Always ensure a secure connection to the earthed conductor (PE), protection class I.
► During operation, make sure that plug-and-socket connections are securely fitted.
► Never operate the vacuum pump with open vacuum flange.
► Never make your own conversions or modifications to the vacuum pump.
► Before returning the vacuum pump, observe the notes in the chapter Service.
