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 capable of maintaining ultimate pressure, see Technical Data [► 24].
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 remains in the machine and does not escape to the environment.
Product Description | 2 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.
3 | Transport Transport WARNING Suspended load. Risk of severe injury! • Do not walk, stand or work under suspended loads. WARNING Lifting the machine using the motor eye bolt. Risk of severe injury! • Do not lift the machine using the eye bolt fitted to the motor. Only lift the machine as shown.
~1 m ~1 m ~1 m Other values may apply after Busch approval • Make sure that the environment of the machine is not potentially explosive. • Make sure that the ambient conditions comply with the Technical Data [► 24]. • Make sure that the environmental conditions comply with the protection class of the motor and the electrical instruments.
• 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.
Use of an inappropriate 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]. 4 mm hex key Check oil level The oil level should stay constant over the lifetime of the oil.
• Busch recommends installing a D-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.
