The vacuum pump appearance may differ from the illustration
• Make sure that the environment of the vacuum pump is not potentially explosive.
• Make sure that the ambient conditions comply with the
Technical Data [

.
• Make sure that the environmental conditions comply with the protection class of the
motor.
• Make sure that the installation space or location is vented such that sufficient cooling
of the vacuum pump is provided.
• Make sure that cooling air inlets and outlets are not covered or obstructed and that
the cooling air flow is not affected adversely in any other way.
• Make sure that the oil sight glass (OSG) remains easily visible.
• Make sure that enough space remains for maintenance work.
• Make sure that the vacuum pump is level within 1° in any direction.
• Check the oil level, see

.
• Make sure that all provided covers, guards, hoods, etc. are mounted.
Version with water-oil heat exchanger:
• Make sure that the cooling water complies with the requirements, see Cooling
Water Connection (Optional).
If the vacuum pump is installed at an altitude greater than 3300 feet above sea level:
• Contact your Busch representative, the motor should be derated or the ambient
temperature limited.
If the vacuum pump is equipped with monitoring devices or sensors:
• Make sure that the monitoring devices are correctly connected and integrated into
a control system such that operation of the vacuum pump will be inhibited if the
safety limit values are exceeded, see

5.2 Connecting Lines / Pipes
• Remove all protective caps before installation.
• Make sure that the connection lines cause no stress on the vacuum pump‘s connec-
tion; if necessary use flexible joints.
• Make sure that the line size of the connection lines over the entire length is at least as
large as the connections of the vacuum pump.
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.
