Safety Prior to handling the machine, this instruction manual should be read and understood. If anything needs to be clarified, please contact your Busch representative. Read this manual carefully before use and keep for future reference. This instruction manual remains valid as long as the customer does not change any- thing on the product.
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.
Transport | 3 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.
• 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 Connection size(s): –...
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 [► 29] and Oil [► 29]. 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.
• 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. • Make sure that the EMC-class of the machine confirms with the requirements of your supply network system, if necessary provide further interference suppression (EMC-Class of the machine see Technical Data [► 29]).

The machine in Aqua version is able to convey up to 100% saturated water va- pour. The conveyance of other vapours than water vapour shall be agreed upon with Busch. • Make sure that any condensate from the suction side will not enter the non-operat- ing machine.
• Clean the machine from dust and dirt. Every 6 years • Have a major overhaul on the machine (contact Busch). 7.2 Oil Level Inspection • Shut down the machine. • When the machine is stopped, wait 1 minute before checking the oil level.
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. Drain pan Cleaning cloth For oil type and oil capacity see Technical Data [► 29] and Oil [► 29].
• 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 bind- ing signed ‘Declaration of Contamination’ (form downloadable from www.buschvacuum.com).
