2 Safety

These Installation and operating instructions con-
tain basic information which must be adhered to
during installation and commissioning. For this
reason, these Installation and operating instruc-
tions must, without fail, be read by the service
technician and the responsible operator before
installation and commissioning. It is not only the
general safety instructions which are listed here
under the main heading of Safety which must be
complied with, but rather also the special safety
instructions which are listed under the following
main headings.

2.1 Identification of notes in the Installation and

operating instructions

The safety instructions contained in these
Installation and operating instructions which, if
they are not observed, could endanger personnel,
are specially marked with the General danger
symbol,

and with

in cases of warnings against electrical voltage.

The word

is included with safety instructions which, if they
are not observed, could endanger the installation
and its function.

2.2 Personnel qualifications

The personnel responsible for installation must be
in possession of the respective qualifications
required for this work.

2.3 Danger in the event of nonobservance of the

safety instructions

The failure to observe the safety instructions
could result in dangers to personnel and
pump/installation. Nonobservance of the safety

instructions can result in the loss of any claims to
damages.
In particular, the failure to observe these instruc-
tions could lead to the following hazards:

• Failure of important functions of the pump/instal-

lation.

• Hazards to personnel resulting from electrical,

mechanical or bacteriological actions,

• Property damage.

2.4 Safety instructions for the operator

The existing regulations regarding accident pre-
vention are to be complied with.
Hazards connected with electrical energy are to
be excluded. The regulations of the VDE (Verband
der Elektrotechnik Elektronik und Informations-
technik e.V.) and of the local energy supply com-
panies are to be complied with.

2.5 Safety instructions for inspection and installa-

tion work

It is the responsibility of the operator to ensure
that all inspection and installation work is carried
out by authorised and qualified professionals who
have acquired sufficient information from a
detailed study of the Installation and operating
instructions.
As a fundamental principle, work may only be car-
ried out on the pump/installation when it/they are
at a standstill.

2.6 Customer's own conversions and spare parts

manufacture

Modifications to the pump/installation are not
permitted except after consultation with the
manufacturer. The use of original spare parts and
manufacturer-authorised accessories promotes
safety. The use of other parts could lead to the
cancellation of liability for the results of such
substitutions.

2.7 Improper use

The operating safety of the supplied pump/instal-
lation is only guaranteed for conventional use in
accordance with Section 1 of the Installation and
operating instructions. It is not permitted to
exceed or fail to meet the limit values specified
in the catalogue/data sheet under any circum-
stances.

3 Transport, handling and storage

The pump/installation is to be checked at once
upon delivery for any damage that may have
occurred in transit. If any damages are found, then
they are to be reported to the transport company
immediately within the time periods specified.

If the material is to be installed later,
then it must be stored in a dry location.
The material must be protected against
impact shocks and all external influ-
ences (moisture, frost, etc.).

Handle the pump carefully so that the geometry
and alignment of the installation are not altered.

The pump is not permitted under any
circumstances to be raised on the fre-
quency converter.
