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.
The maintenance instructions must be observed and respected.
Is 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.
