Page 7: 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 capable of maintaining ultimate pressure, see Technical Data [► 26]. -

Page 9: Storage
• Drain the operating liquid from the machine and the system before storage. • Or add an anti-freeze solution. After testing, all Busch Dolphin vacuum pumps are vented and drained. 4.1 Short Term (Up to 3 Months) • Seal all apertures with adhesive tape or provided caps. -
Page 10: Installation
• Make sure that the coupling is correctly aligned, see Fitting the Coupling [► 15]. 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. -

Chemical compat- ibility should always be checked by competent personnel before use, particular atten- tion should be paid to elastomer material selection. If in doubt, please consult Busch. 5.4 Fitting the Coupling WARNING Unprotected coupling. -
Page 16: Electrical Connection
• 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. -
Page 17: Commissioning
Commissioning | 6 • Watch the fan wheel of the motor and determine the direction of rotation just before the fan wheel stops. If the rotation of the motor must be changed: • Switch any two of the motor phase wires. For motor wiring and wiring diagrams, please refer to motor manufacturers instruction manuals. -
Page 18: Preventing Cavitation
6 | Commissioning • Make sure that the operating liquid level is at the machine shaft centre. • Check the operation of all automatic valves before start up – Machines with gland packing for shaft sealing: loosen the packing gland plate and apply a few drops of oil to the packing for lubricating purpose. -
Page 19: Maintenance
Liquid Connection [► 12]. • Check the machine for liquid leaks - in case of leaks have the machine repaired (contact Busch). • If applicable, check gland packing leakage rate (45 to 60 drips per minute) and adjust as required. -
Page 20: Overhaul
• Decontaminate the machine as much as possible and state the contamination status in a ‘Declaration of Contamination’. Busch will only accept machines that come with a completely filled in and legally binding signed ‘Declaration of Contamination’ (form downloadable from www.buschvacuum.com). -
