●
Make sure that the installation space or location is vented such
that a sufficient cooling of the vacuum pump is warranted
CAUTION
_ac
During operation the surface of the vacuum pump may reach tem-
peratures of more than 70 °C.
Risk of burns!
●
Make sure that the vacuum pump will not be touched inadver-
tently during operation, provide a guard if appropriate
Suction Connection
CAUTION
_a
Intruding foreign objects or liquids can destroy the vacuum pump.
In case the inlet gas can contain dust or other foreign solid particles:
●
Make sure that the suction line fits to the suction connection (a) of
the vacuum pump
●
Make sure that the line size of the suction line over the entire
length is at least as large as the suction connection (a) of the
vacuum pump
In case the length of the suction line exceeds 2 m it is prudent to use
larger line sizes in order to avoid a loss of efficiency and an overload of
the vacuum pump. Seek advice from your Busch representative!
In case the vacuum shall be maintained after shutdown of the vacuum
pump:
◆
Provide a manual or automatic operated valve (= non-return
valve) in the suction line
●
Make sure that the suction line does not contain foreign objects,
e.g. welding scales
Gas Discharge
Version with top liquid separator:
The discharge piping should not exceed an elevation more than
600 mm above the discharge flange (c) of the pump housing until the
liquid is separated. Too high an elevation will cause back pressure and
possible drive motor overload.
The discharged gas must flow without obstruction. It is not permitted
to shut off or throttle the discharge line or to use it as a pressurised
air source.
●
Make sure that the discharge line fits to the gas discharge (c) of
the vacuum pump
●
Make sure that the line size of the discharge line over the entire
length is at least as large as the gas discharge (c) of the vacuum
pump
In case the length of the discharge line exceeds 2 m it is prudent to use
larger line sizes in order to avoid a loss of efficiency and an overload of
the vacuum pump. Seek advice from your Busch representative!
●
Make sure that the discharge line either slopes away from the
vacuum pump or provide a liquid separator or a drip leg with a
drain cock, so that no liquids can back up into the vacuum pump
Electrical Connection / Controls
●
Make sure that the stipulations 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;
Ú
page 16: note in
the EC-Declaration of Conformity).
●
Make sure that the power supply for the drive motor is compatible
with the data on the nameplate of the drive motor
●
Make sure that an overload protection according to EN 60204-1 is
provided for the drive motor
●
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:
◆
Provide the electrical connection with grommets that serve as
strain-relief
Installation
Mounting
●
Make sure that the Installation Prerequisites (
Ú
page 5) are com-
plied with
●
Set down or mount the vacuum pump at its location
●
Make sure that the base plate is not bent and that the flexible cou-
pling is properly aligned
Note
: A misaligned coupling leads to increased loads onto the cou-
pling and the bearings and hence to premature failure of the
vacuum pump.
Mounting the V-belt Drive
●
Mount the v-belt drive
Checking the Alignment of the Pulleys
●
Make sure that the v-belt drive is properly aligned:
Proper alignment: both pulleys / pulley packages in one plane
Improper alignment: axial offset
Improper alignment: pulleys / pulley packages angled
●
Adjust the v-belt tension after the installation of the operating liq-
uid supply system (the vacuum pump shall not run dry)
