Connecting Lines / Pipes
●
Remove all protective covers before installation.
●
Make sure that the connection lines cause no stress on the connection of the machine; if neces-
sary 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 long connection lines, it is advisable to use larger line sizes in order to avoid a loss of effi-
ciency. Seek advice from your Busch representative.
