Installation prerequisites
CAUTION
In case of non-compliance with the installation prerequisites,
particularly in case of insufficient cooling:
Risk of damage or destruction of the vacuum pump and its
components!
Risk of personal injury!
The installation prerequisites must be complied with.
l
Please ensure that the integration of the vacuum pump is
compliant with the safety requirements of the Machine Directive
2006/42/EC (concerning the responsibility of the system’s
manufacturer into which the vacuum pump is to be incorporated,
please also refer to the note in the EU-Declaration of Conformity).
Local installation
l
Make sure that the following ambient conditions are adhered to:
–
Ambient temperature: -20 ... 40 °C
–
Ambient pressure: atmospheric pressure
–
Humidity range: 20 to 95%
–
Altitude: up to 1000 m
l
Make sure that the environment conditions correspond to the
protection class of the motor (in accordance with the motor
nameplate)
l
Make sure that the vacuum pump is placed on or fastened to a
horizontal surface
l
Make sure that the vacuum pump is level and even
l
Make sure that the vacuum pump cannot inadvertently or
intentionally be used as a support for heavy objects
l
Make sure that the vacuum pump cannot be hit by falling objects
l
Make sure that the vacuum pump is easily accessible and that the
selected installation site fulfills the requirements for assembly/
dismantling
l
Make sure that no temperature-sensitive part (such as plastic,
wood, cardboard, paper, electronic parts) comes into direct contact
with the hot surfaces of the vacuum pump
l
Make sure that the installation site or assembly area is ventilated in
such a way that adequate cooling of the vacuum pump is assured
CAUTION
During operation the surface of the vacuum pump may exceed
temperatures of 90° C.
Risk of burns!
l
Make sure that the vacuum pump cannot be touched inadvertently
during operation, provide a guard if necessary
l
Make sure that the oil sight glasses (OSG) will remain easily
accessible
If the oil change is meant to be performed on site:
u
Make sure that the oil drain plugs as well as the oil filler plugs,
are easily accessible
Suction Connection
l
Make sure that the protection that prevents the ingress of foreign
matter during transport, has been removed before connecting up
the vacuum pump to the piping
CAUTION
Do not put hands into the inlet aperture.
Risk of body damage !
CAUTION
The ingress of foreign objects or liquids can destroy the vacuum
pump.
In case the inlet gases can contain dust or other foreign solid particles:
u
Make sure that a suitable filter or protection screen is installed
at the inlet of the vacuum pump
l
Make sure that the nominal diameter of the inlet line is at least
equal to the diameter of the inlet flange 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 leak-proof
piping
CAUTION
Once the inlet line has been connected up, make sure that the
system does not leak. Leakage of dangerous substances must be
prevented!
l
Make sure that the inlet line is equipped with a shut-off device
upstream of the inlet flange, so that the flow of drawn gases can
be stopped
l
Make sure that the inlet line does not exercise any pressure on the
inlet flange. Use bellows if necessary
l
Make sure that the load on the inlet flange does not exceed 90 kg.
l
The inlet flange has the following dimension:
–
DN 80 PN6 or ISO-K DN 63
In case of long inlet lines the pipe diameter should be larger than the
inlet flange to prevent a drop in the performance of the vacuum pump.
If you have any doubts, contact your Busch representative.
