5.2 Connecting Lines / Pipes
• Remove all protective covers before installation.
• Make sure that the connections are gas tight.
• Make sure that the connection lines cause no stress on the machine‘s connection; 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 machine.
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.

The connection lines can build up an electrostatic charge.
Risk of severe injury!
Risk of explosion!
• The connection lines must be made out of conductive material or provisions must be
made against creating an electrostatic charge.
