  • Page 5: Operating Principle

    Conveying of other media leads to an increased thermal and/or mechanical load on the machine and is permissible only after a consultation with Busch. The machine is intended for the placement in a non-potentially explosive environment. The machine is not capable of maintaining ultimate pressure.

    2 | Product Description 2.3.1 Gas Tight Version WARNING Media potentially dangerous. Risk of poisoning! Risk of infection! • Wear appropriate personal protective equipment in case of high concentration of the medium in the ambient atmosphere of the machine. The gas tight version is a design option for applications where the process gas re- mains in the machine and does not escape to the environment.

    Transport | 3 2.5 Optional Accessories 2.5.1 Inlet Filter The inlet filter protects the machine against dust and other solids in the process gas. The inlet filter is available with a paper or polyester cartridge. 2.5.2 Vacuum Relief Valve The ultimate pressure is limited by a vacuum relief valve. The vacuum relief valve is adjusted ex-works to the minimum permitted ultimate pressure (see nameplate).

    • Make sure that all provided covers, guards, hoods, etc. are mounted. If the machine is installed at an altitude greater than 1000 meters above sea level: • Contact your Busch representative, the motor should be derated or the ambient temperature limited.

  • Page 10: Filling Oil

    Risk of premature failure! Loss of efficiency! • Only use an oil type which has previously been approved and recommended by Busch. For oil type and oil capacity see Technical Data [► 24] and Oil [► 24]. Check oil level The oil level should stay constant over the lifetime of the oil. If the level does fall, this indicates a leak and the machine requires repair.

  • Page 11: Electrical Connection

    • Busch recommends installing a K-curve circuit breaker. • Make sure that the motor of the machine will not be affected by electric or electro- magnetic disturbance from the mains; if necessary seek advice from Busch. • Connect the protective earth conductor.
