In case lifting gear is used:
◆
Attach the lifting gear to a crane hook with safety latch
CAUTION
_a
Tilting a vacuum pump that is already filled with oil can cause large
quantities of oil to ingress into the cylinder.
Starting the vacuum pump with excessive quantities of oil in the cyl-
inder will immediately break the vanes and ruin the vacuum pump.
Once the vacuum pump is filled with oil it shall not be lifted any-
more.
●
Prior to every transport make sure that the oil is drained
Storage
Short-term Storage
Version with gas ballast without ball-valve, with paper filter:
◆
Close the paper filter of the gas ballast device with
adhesive tape
●
Make sure that the suction connection and the gas discharge are
closed (leave the provided plugs in)
●
Store the vacuum pump
–
if possible in original packaging,
–
indoors,
–
dry,
–
dust free and
–
vibration free
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!
Version with gas ballast without ball-valve, with paper filter:
◆
Close the paper filter of the gas ballast with adhe-
sive tape
●
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 (
Ú
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 98/37/EC are complied with (in the responsibility of the de-
signer of the machinery into which the vacuum pump is to be
incorporated.
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: see “Oil”
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 20 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
