Safety

Intended use

DEFINITION

: For the purpose of correct understanding, the “handling”

of the vacuum pump implies the transport, storage, installation,
commissioning, the influence on operating conditions, maintenance,
troubleshooting and overhaul of the vacuum pump.

The vacuum pump is intended for industrial use. It should only be
handled by qualified staff.

The different applications for use and operational limits of the vacuum
pump as laid out in 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 end user.

The need for personal safety regulations depends mainly on the
application the pump will be used in. The end user must provide the
operators with all necessary means and tools and must inform his
personnel about any dangers emanating from the processed products.

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 observed and respected.

It is vital that these installation and maintenance instructions are read
and understood before the vacuum pump is used. If you have any
doubts, please contact your local Busch representative.

Safety information

The vacuum pump has been designed and manufactured in accordance
with the latest technical and safety standards. Nevertheless, residual
risks may remain.

A lot of safety information is mentioned in these Installation and
Operating Instructions as well as on the pump. The safety instructions
must be observed. The safety information can quickly be detected
through key words like DANGER, WARNING and CAUTION and is
defined as follows:

DANGER

Disregard of this safety note will always lead to accidents with po-
tentially fatal injuries and serious damages.

WARNING

Disregard of this safety note may lead to accidents with potentially
fatal injuries and serious damages.

CAUTION

Disregard of this safety note will always lead to accidents with minor
injuries and damages to property.
