— The selected diameter of the air inlet and outlet pipelines must be at
least two nominal widths greater than that specifi ed by the connection fl ange
on the vacuum pump!
— In order to prevent corrosion in the pipes, we recommend the use of galvanised or
stainless steel piping.
— Provide a supporting fan in case of longer or widely branched pipelines and high
differential pressures. Please contact the manufacturer for more information.
— The exit point of lines must be protec-
ted with a rainguard to prevent water from
reaching the dryer inside (see fi gure).
— if necessary, the exit point of lines
should be barred with grilles in order to pre-
vent foreign objects or animals from entering
the dryer.
— The outlet line must be installed in such
a way that there is no risk of injury from hot
regeneration gas.

Rainguard when line exits to the side
— If both an inlet and an outlet line are installed, ensure that the escaping hot regener-
ation gas is not again drawn into the inlet line. The outlet opening of the outlet line should
thus be positioned higher than the inlet opening.
— If both an inlet and an outlet line are installed, ensure that condensation water cannot
drop from the outgoing line onto the supply air intake when installing supply as well as out-
going lines. For this purpose, the outlet line should be routed farther to the outside than the
inlet line.
— Route the supply line at suffi cient height to prevent taking in coarse dirt or other detri-
mental foreign objects.
