Safety
Intended use
DEFINITION
: For the purpose of these instructions, “handling” the va-
cuum pump means the transport, storage, installation, commissioning,
influence on operating conditions, maintenance, troubleshooting adn
overhaul of the vacuum pump.
The vacuum pump is intended for industrial use. It should only be han-
dled by qualified personnel.
The different application of the puml and operational limits according
to the “Product Description” and the “Installation Prerequisites” of
the vacuum pump must be observed both by the manufacturer of the
machinery into which the vacuum pump is to be incorporated, and by
the operator.
The maintenance instructions must be adhered to.
Prior to handling the vacuum pump, these operating instructions must
be read and understood. If anything remains to be clarified, please
contact your Busch representative!
Safety notes
The vacuum pump has been designed and manufactured according to
the latest technical standards and in accordance with current safety
requirements. Nevertheless, residual risks may remain. These operating
instructions inform about potential hazards where appropriate. Safety
notes are tagged with one of the keywords DANGER, WARNING and
CAUTION as follows:
DANGER
Disregard of this safety note will always lead to accidents with fa-
tal or serious injuries.
WARNING
Disregard of this safety note may lead to accidents with fatal or se-
rious injuries.
CAUTION
Disregard of this safety note may lead to accidents with minor inju-
ries or property damage.
Sound Emissions
For the sound pressure level in free field operation according to EN ISO
2151, please see “Technical Data”.
CAUTION
The vacuum pump emits noise of medium intensity.
Risk of damage to hearing.
People staying in the vicinity of a non noise insulated vacuum pump
over extended periods sof time must wear suitable ear protection.
Transport
CAUTION
Please check the weight of the vacuum pump before lifting it up
(see "Technical Data")
Use adequate lifting gear for this.
Seco vacuum pumps pass a rigorous operating test in the factory and
are packed carefully to avoid transit damage.
The suction and the discharge apertures are sealed with plugs so that
no dirt can enter the pump during transport. These protections must be
removed before connecting the vacuum pump.
Please check packaging on delivery for any transport damage.
The pump can be lifted from the packing with a suitable lifting device
using the lifting bracket on the pump.
Packing materials should be disposed of according to environmental
laws, or reused.
CAUTION
Do not walk, work or stand under suspended loads.
Storage
Short-term Storage
l
Make sure that the suction connection/gas inlet and the gas dis-
charge/pressure connection are closed (refit the plugs the pump
was delivered with)
l
Store the vacuum pump
–
if possible in its original packaging,
–
indoors,
–

–
vibration free
Installation and
Commissioning
Installation prerequisites
CAUTION
In case of non-compliance with the installation prerequisites, parti-
cularly 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.
l
Make sure that the integration of the vacuum pump is carried out
in such a way that the essential safety requirements of the Ma-
chine Directive 2006/42/EC are complied with (it is the responsibi-
