Connection
lines/pipes
ATTENTION!
Danger
of
damage
to
the
vacuum
system
from
foreign
bodies
in
the
pipes.
•
Remove
all
foreign
matter
(welding
beads,
filings,
etc.)
from
the
pipelines!
This
may
be
done
by
flushing
or
blowing
through
pipelines.
•
The
client
must
ensure
that
the
pipework
at
the
inlet
is
clean.
.
ATTENTION!
Vacuum
system
can
be
damaged
by
tensile
or
compressive
stresses
on
pipeline
connec
‐
tions!
•
If
stresses
could
occur,
use
compensators
to
connect
pipelines.
ATTENTION!
Condensate
damages
vacuum
pumps!
•
Lay
the
piping
on
the
intake
and
pressure
sides
at
an
angle
to
prevent
accumulated
con
‐
densation
from
entering
the
vacuum
pump.
The
line
cross
‐
section
of
the
connection
lines
must
have
at
least
the
same
cross
‐
section
as
the
connections
of
the
vacuum
system
across
the
entire
length.
In
case
of
very
long
connection
lines,
it
is
recommended
to
use
lines
with
larger
cross
‐
sections
to
avoid
loss
of
efficiency.
Please
contact
your
contact
person
from
Busch.
