WARNING
The vacuum system can be damaged by tensile or compressive
stresses on pipe connections!
l
If stresses could occur, use compensators to connect pipes!
WARNING
The vacuum system can be damaged by condensate!
l
Fit traps to inlet and discharge sided pipes to prevent condensate
getting into vacuum pumps!
Inlet connection
l
Make sure that the protection that was attached to prevent pene-
tration of particles during transport has been removed before the
vacuum system is connected to the vacuum line
CAUTION
Do not put hands into the inlet aperture.
Risk of body damage!
CAUTION
The intake of liquids or solid particles can lead to the destruction of
the vacuum system
If the sucked gas contains dusts or solid foreign bodies:
u
Make sure that a filter or protective grating is installed at the
extraction point
l
Make sure that the nominal diameter of the intake line is at least
equal to the diameter of the intake flange of the vacuum system to
prevent a drop in the performance of the vacuum system in the
case of a smaller cross-section
l
Make sure that the vacuum system is connected with leakproof
lines
CAUTION
When the intake lines have been connected, make sure that the sys-
tem does not leak. Leakages of dangerous substances must be pre-
vented!
l
Make sure that the intake lines are equipped with a shut-off device
upstream of the intake flange so that the flow of sucked gas can
be stopped
l
Make sure that the intake lines do not exercise any force on the in-
take flange. Mount bellows if necessary
l
The inlet flange has the following dimension:
–
DN 250 ISO-K for the Roots WY A075 inlet (DS 8163, 8264)
–
DN 100 ISO-K for the COBRA DP 600 C inlet (inlet backing
vacuum pump)
In the case of long intake lines the line cross-section should be larger
than the intake flange to prevent a drop in the performance of the
vacuum system. If you have any doubts, contact your Busch represen-
tative.
Discharge connection
CAUTION
Do not put hands into the outlet aperture.
Risk of body damage!
The following instructions for connection to the discharge only apply if
the sucked gas is discharged by the vacuum system into a suitable en-
vironment.
l
Make sure that the protection that was attached to prevent pene-
tration of particles during transport has been removed before the
vacuum system is connected to the vacuum line
l
Make sure that the nominal diameter of the exhaust line is at least
equal to the diameter of the exhaust flange of the vacuum system
to prevent a drop in the performance of the vacuum system in the
case of a smaller cross-section
Make sure that the vacuum system is connected with leakproof lines
CAUTION
When the discharge lines have been connected, make sure that the
vacuum system does not leak. Leakages of dangerous substances
must be prevented!
l
Make sure that the discharge lines are equipped with a shut-off
device upstream of the intake flange so that the flow of sucked gas
can be stopped
l
Make sure that no shut-off devices are mounted in the discharge
line
l
Make sure that the discharge lines do not exercise any force on the
intake flange. Mount bellows if necessary
l
The discharge flange has the following dimension:
–
DN 63 ISO-K for each backing vacuum pump DP 600
In the case of long discharge lines, the line cross-section should be
larger than the discharge flange to prevent a drop in the performance
of the vacuum system. If you have any doubts, contact your Busch
representative.
Cooling water connection
The cooling water is generally connected with a hose (leakproof
against oxygen).
l
Connect the cooling water hose to the vacuum system distributor
l
Connect the distributor to the cooling water supply
The cooling water outlet must be unpressurised.
