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The Declaration of Conformity from the manufacturer is no longer valid if the operator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 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.
► Before working on the high vacuum connection, wait until the rotor has stopped completely (rota-
tion speed f = 0).
► Never put the device into operation with the high vacuum connection open.
► 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.
