Conservation
In case of adverse ambient conditions (e.g. aggressive atmosphere, fre-
quent temperature changes) conserve the vacuum pump immediately.
In case of favourable ambient conditions conserve the vacuum pump if
a storage of more than 3 months is scheduled.
During the test run in the factory the inside of the vacuum pump was
completely wetted with oil. Under normal conditions a treatment with
conservation oil is therefore not required. In case it is advisable to treat
the vacuum pump with conservation oil because of very adverse stor-
age conditions, seek advice from your Busch representative!
Make sure that all ports are firmly closed; seal all ports that are not
sealed with PTFE-tape, gaskets or o-rings with adhesive tape
Note
: VCI stands for “volatile corrosion inhibitor”. VCI-products (film,
paper, cardboard, foam) evaporate a substance that condenses in mo-
lecular thickness on the packed good and by its electro-chemical prop-
erties effectively suppresses corrosion on metallic surfaces. However,
VCI-products may attack the surfaces of plastics and elastomers. Seek
advice from your local packaging dealer! Busch uses CORTEC
VCI 126 R film for the overseas packaging of large equipment.
Wrap the vacuum pump in VCI film
Store the vacuum pump
–
if possible in original packing,
–
indoors,
–
dry,
–
dust free and
–
vibration free.
For commissioning after conservation:
Make sure that all remains of adhesive tape are removed from the
ports
Commission the vacuum pump as described in the chapter Installa-
tion and Commissioning (
page 5)
Installation and
Commissioning
Installation Prerequisites
CAUTION
_a
In case of non-compliance with the installation prerequisites, partic-
ularly in case of insufficient cooling:
Risk of damage or destruction of the vacuum pump and adjoining
plant components!
Risk of injury!
The installation prerequisites must be complied with.
Make sure that the integration of the vacuum pump is carried out
such that the essential safety requirements of the Machine Direc-
tive 2006/42/EC are complied with (in the responsibility of the de-
signer of the machinery into which the vacuum pump is to be
incorporated;
page 18: note in the EC-Declaration of Confor-
mity)
Mounting Position and Space
Make sure that the environment of the vacuum pump is not po-
tentially explosive
Make sure that the following ambient conditions will be complied
with:
–
ambient temperature: 12 ... 30 °C
If the vacuum pump is installed in a colder environment than al-
lowed with the oil used:
Fit the vacuum pump with a temperature switch and control
the vacuum pump such that it will start automatically when
the oil sump temperature falls below the allowed temperature
–
ambient pressure: atmospheric
Make sure that the environmental conditions comply with the pro-
tection class of the drive motor (according to the nameplate)
Make sure that the vacuum pump will be placed or mounted hori-
zontally
Make sure that in order to warrant a sufficient cooling there will be
a clearance of minimum 2 cm between the vacuum pump and
nearby walls
Make sure that no heat sensitive parts (plastics, wood, cardboard,
paper, electronics) will touch the surface of the vacuum pump
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
Make sure that the sight glass (g) will remain easily accessible
If the oil change is meant to be performed on location:
Make sure that the drain port (g) and the filling port (b) will
remain easily accessible
Make sure that enough space will remain for the removal and the
reinsertion of the exhaust filter
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 a suitable filter (5 micron or less) is installed
upstream the vacuum pump
Make sure that the suction line fits to the suction connection (c) of
the vacuum pump
Make sure that the gas will be sucked through a vacuum-tight
flexible hose or a pipe
In case of using a pipe:
Make sure that the pipe will cause no stress on the vacuum
pump’s connection, if necessary use an expansion joint
Make sure that the line size of the suction line over the entire
length is at least as large as the suction connection (c) 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. Seek advice from your Busch
representative!
If two or more vacuum pumps work on the same suction line, if the
volume of the vacuum system is large enough to suck back oil or if the
vacuum shall be maintained after switching off the vacuum pump:
Provide a manual or automatic operated valve (= non-return
valve) in the suction line
