BUSCH COBRA BC 1000, Instruction Manual

Page: 11 / 24

CAUTION
When the intake lines have been connected, make sure that the
system does not leak. Leakages of dangerous substances must be
prevented!
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
intake flange. Mount bellows if necessary
l The inlet flange has the following dimension:
–
BC 1000 F: DN 100 ISO-K
–
BC 2000 F: DN 160 ISO-K
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 pump. If you have any doubts, contact your Busch
representative.
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 pump into a suitable
environment.
l Make sure that the protection that was attached to prevent
penetration of particles during transport has been removed before
the vacuum pump 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 pump
to prevent a drop in the performance of the vacuum pump in the
case of a smaller cross-section
l
Make sure that the vacuum pump is connected with leakproof lines
CAUTION
When the discharge lines have been connected, make sure that the
system does not leak. Leakages of dangerous substances must be
prevented!
l Make sure that the discharge line is mounted in such a way that
condensate cannot penetrate into the pump (siphon trap, gradient)
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
discharge flange. Mount bellows if necessary
l The discharge flange has the following dimension:
–
DN 40 ISO KF
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 pump. If you have any doubts, contact your Busch
representative.
Cooling water connection
The cooling water is generally connected with a hose.
The cooling water outlet must be unpressurised.
Connection diameter: 3/8 NPT
Nitrogen connection
The nitrogen is connected with a pipe (leakproof against oxygen).
Connection diameter: 1/4 NPT
