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 [► 20].
3 | Transport Transport NOTICE In case the machine is already filled with oil. Tilting a machine that is already filled with oil can cause large quantities of oil to in- gress into the cylinder. Starting the machine with excessive quantities of oil in the cylinder will immediately break the vanes and ruin the machine! •...
• 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.
In case of very long connection lines it is advisable to use larger line sizes in order to avoid a loss of efficiency. Seek advice from your Busch representative. 5.2.1 Suction Connection NOTICE Ingress of foreign objects or liquids.
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 [► 20] and Oil [► 20]. Check oil level 0870160580_PB_PC0004C_B0001_IM_en...
• Provide an overload protection according to EN 60204-1 for the motor. • 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.
Installation | 5 5.4.2 Wiring Diagram Three-Phase Motor NOTICE Incorrect direction of rotation. Risk of damage to the machine! • Operation in the wrong direction of rotation can destroy the machine in a short time! Prior to start-up, ensure that the machine is operated in the right direction. •...
6 | Commissioning Commissioning NOTICE The machine can be shipped without oil. Operation without oil will ruin the machine in short time! • Prior to commissioning, the machine must be filled with oil, see Filling Oil [► 8]. CAUTION During operation the surface of the machine may reach temperatures of more than 70°C.
Risk of injuries! Risk of premature failure and loss of efficiency! • Respect the maintenance intervals or ask your Busch representative for service. • Shut down the machine and lock against inadvertent start up. • Vent the connected lines to atmospheric pressure.
Weekly • Check the oil level, see Oil Level Inspection [► 14]. • Check the machine for oil leaks - in case of leaks have the machine repaired (contact Busch). Monthly In case of an inlet filter being installed: • Check the inlet filter cartridge, replace if neces- sary.
