Before disassembling any cooling water lines, leave the pump to cool down, shut off the feed line. 300304403_002_C0 - 11/2016 - © Leybold...

  • Page 9: Electrical Hazards

    The pump must only be operated at the frequency specified for the motor. Use only the Leybold frequency converter. Install a suitable motor protection for the electric motor before starting up for the first time. Note the information in these Operating Instructions and on the nameplate.

  • Page 10: Thermal Hazards

    Operating the pump with less than the specified amount of cooling water will result in excessively high surface temperatures. There exists the risk of suffering burns. 300304403_002_C0 - 11/2016 - © Leybold...

  • Page 11: Hazards Caused By Materials And Substances

    Since not all application related hazards for vacuum systems can be described in detail in these Operating Instructions, Leybold has avail- able a separate document (Safety Booklet) in which the hazards and general safety concepts for design, operation and maintenance of vac- uum systems are explained.
  • Page 12 For this see Section 5.1 Service at Leybold. Leybold is not in a position to perform servicing (repairs) and waste disposal of radioactively contaminated pumps. Both needs to be ensured from the side of the user.
