lity of the designer of the machinery into which the vacuum pump
is to be incorporated; see also the note in the EC-Declaration of
Conformity)
Installation Position and space
l
Make sure that the environment of the vacuum pump is not po-
tentially explosive
l
Make sure that the following ambient conditions will be complied
with:
–
Ambient temperature: 12 to 30 °C
–
Ambient pressure: atmospheric
l
Make sure that the environmental conditions comply with the pro-
tection class of the drive motor (according to the motor name
plate)
l
Make sure that the vacuum pump will be placed or mounted hori-
zontally
l
Make sure that the base for placement / mounting is even
l
Make sure that the vacuum pump can neither inadvertently nor in-
tentionally be stepped on and cannot be used as a support for hea-
vy objects
l
Make sure that the vacuum pump cannot be hit by falling objects
l
Make sure that in order to warrant sufficient cooling, there is a
clearance of minimum 0,5 m between the fan hood and nearby
walls
l
Make sure that no temperature sensitive parts (plastics, wood,
cardboard, paper, electronics) will touch the surface of the vacuum
pump
l
Make sure that the installation space or location is vented in such a
way that a sufficient cooling of the vacuum pump is warranted
CAUTION
During operation the surface of the vacuum pump may reach tem-
peratures of more than 100°C.
Risk of burns!
Suction Connection
CAUTION
The ingress foreign objects or liquids can destroy the vacuum pump.
In case the inlet gas contains dust or other foreign solid particles:
u
Make sure that a suitable filter (5 microns or less) is installed
upstream of the vacuum pump
l
Make sure that the suction line fits the suction connection/gas inlet
(a) of the vacuum pump
l
Make sure that the gas will be drawn through a vacuum-tight
flexible hose or a pipe
In case of being used a pipe :
u
Make sure that the pipe will cause no stress on the vacuum
pump’s connection, if necessary use bellows
l
Make sure that the line diameter of the suction line over its entire
length is at least as large as the suction connection/gas inlet (a) of
the vacuum pump
In case of very long suction lines, it is prudent to use larger line sizes in
order to avoid a loss of efficiency. Please seek the advice from your
Busch representative
If two or more vacuum pumps work off the same suction line, if the
volume of the vacuum system is large enough to suck back oil or if the
vacuum has to be maintained after switching off the vacuum pump:
u
Provide a manual or automatic valve (= non-return valve) in
the suction line
(the non-return valve that is installed inside the suction connection is
not meant to be used for this purpose!)
l
Make sure that the suction line does not contain any foreign ob-
jects, e.g. welding slag or swarf
Discharge connection
The following guidelines for the discharge line do not apply if the aspi-
rated air is discharged into the environment right behind the vacuum
pump.
CAUTION
If air is discharged into rooms occupied by people, sufficient ventila-
tion must be provided for.
l
Make sure that the discharge line fits the gas discharge (b) of the
vacuum pump
In case of being used a pipe:
u
Make sure that the pipe will cause no stress on the discharge
connection, if necessary use bellows
l
Make sure that the line diameter of the discharge line over its en-
tire length is at least as large as the gas discharge of the vacuum
pump
In case of very long discharge lines it is prudent to use larger line sizes
in order to avoid a loss of efficiency and an overload of the vacuum
pump. Please seek the advice from your Busch representative
l
Make sure that the discharge line either slopes away from the va-
cuum pump or provide a liquid separator or a drip leg with a drain
cock, so that no condensates can enter the vacuum pump
WARNING
Discharge lines made from non-conducting material can build up
static charge.
The discharge line must be made of conducting material or provi-
sions must be made against static charge
Electrical connection / Controls
l
Make sure that the regulations acc. to the EMC-Directive
2004/108/EC and Low-Voltage-Directive 2006/95/EC as well as
the EN-standards, electrical and occupational safety directives and
the local or national regulations, respectively, are complied with
(this is the responsibility of the designer of the machinery into
which the vacuum pump is to be incorporated; see also the note in
the EC-Declaration of Conformity).
l
Make sure that the power supply is compatible with the data on
the name plate of the drive motor
l
Make sure that an overload protection according to EN 60204-1 is
provided for the drive motor
l
Make sure that the drive of the vacuum pump will not be affected
by electric or electromagnetic disturbance from the mains; if neces-
sary seek advice from the Busch service
In case of mobile installation:
u
Provide the electrical connection with grommets that serve as
strain relief
Installation
Mounting
l
Make sure that the “Installation Prerequisites” are complied with
l
Install or mount the vacuum pump at the location that has been
provided for it
