Safety
Intended use
DEFINITION
: To rule out any misunderstanding, the term “handling”
of the vacuum pump covers transport, storage, installation and
operation of the pump as well as effects on operating states and
troubleshooting on the vacuum pump.
The vacuum pump is intended for industrial use. It may only be
operated by qualified personnel.
The different application possibilities and limit values for operation
described in “Product description” and “Installation requirements”
must be observed by the manufacturer of the system into which the
vacuum pump is to be integrated and by users.
The need for personal safety regulations depends in principle on the
type of use. The operator must provide the users with the necessary
means and must inform his personnel about the dangers emanating
from the processed product.
The operator of the vacuum pump must observe the safety regulations
and must train and instruct his personnel accordingly.
Local regulations regarding the motors and electric control elements
must be observed when installing the pump in potentially explosive
environments.
The maintenance instructions must be followed and observed.
These installation and maintenance instructions must be read and
understood before the vacuum pump is used. If you have any doubts,
contact your Busch representative.

Transport
The COBRA NS vacuum pumps are tested and checked in our factory
before careful packing. Check the packaging for transport damage
when the goods arrive. The pump can withstand temperatures
between -25°C and +55°C during transport.

CAUTION
Please check out the weight of the vacuum pump before lifting it up
(see "Technical Data"or pump nameplate).
Use adequate lifting gear for this.
NOTE
: The suspension eyes are located at about the centre-of-gravity
of the vacuum pump. If the vacuum pump is equipped with accessories
that could influence the centre-of-gravity, this must be taken into
account when lifting and a belt must additionally be attached to a
specific point.
