Compressed air connection

Warning
A defective connection to the compressed
air system may jeopardize safe operation of
the compressed air system.
When connecting the compressor outlet to
the customerʼs existing compressed air
system, check that the necessary operating
temperatures, operating pressures as well
as the necessary connecting flange or
connecting thread are appropriate and in
perfect working order (see fig. 9).
For connections with hoses, take steps so
that if an end breaks free it wonʼt "whip"
around dangerously.

The compressed air line system is connected at the
compressed air supply of the screw compressor
( - 1 - Fig. 9).

For this you should use a flexible connection
(e.g. compressed air hose, compensator).
Connection: sleeve G 1" (1" NPT)
NOTE
After-coolers, separators, collecting reservoirs
and the compressed air lines must be equipped
with drain facilities at their lowest points to drain
collected liquids. These facilities have to be
fitted to allow the observance of the draining of
such liquids.
Hand-operated drain facilities have to be
actuated in accordance with the operating
instructions.
Automatic drain facilities have to be checked for
proper function at regular intervals. When
draining condensates into a collecting line,
which also collects the condensate from other
machines, make sure that the collecting line is
free from back pressure at all lines.
Condensate may contain oil! When draining
condensate, observe the corresponding
regulations for waste water disposal.
