2 Safety
This section lists all the generally applicable
safety instructions and technical information. In
addition, all the other sections contain specific
safety instructions and technical information. All
instructions and information must be observed
and followed during the various phases of the
pump’s life cycle (installation, operation, main-
tenance, transport etc.)! The operator is respon-
sible for ensuring that all personnel follow these
instructions and guidelines.
2.1 Instructions and safety instructions
This manual uses instructions and safety instruc-
tions for preventing injury and damage to prop-
erty. To clearly identify them for personnel, the
instructions and safety instructions are distin-
guished as follows:
• Instructions appear in “bold” and refer directly to
the preceding text or section.
• Safety instructions are slightly “indented and
bold” and always start with a signal word.
•

•
Warning

•

•
Caution
(instruction without symbol)
Substantial property damage can occur. Irrepa-
rable damage is possible!
• Safety instructions that refer to personal injury
appear in black and are always accompanied by a
safety symbol. Danger, prohibition or instruction
symbols are used as safety symbols.
Example:
Danger symbol: General hazard
Danger symbol, for example, electrical current
Symbol for prohibited action, e.g. No entry!
Instruction symbol, for example, wear protec-
tive clothing
The safety symbols used conform to the generally
applicable directives and regulations, such as DIN
and ANSI.
• Safety instructions that only refer to property
damage are printed in grey, without safety sym-
bols.
2.2 General safety information
• When installing or removing the pump, never
work alone in rooms and sump. A second person
must always be present.
• The pump must always be switched off before
any work is performed on it (assembly, disman-
tling, maintenance, installation). The pump must
be disconnected from the electrical system and
secured against being switched on again. All
rotating parts must have come to a standstill.
• The operator must report any faults or irregulari-
ties that occur to a line manager immediately.
• The end-user must shut down the equipment im-
mediately if defects occur that represent a safety
risk. These include:
• Failure of the safety and/or monitoring devices
• Damage to important parts
• Damage to electrical equipment, cables and
insulations.
• Tools and other objects should only be kept in
their designated places so that they can be found
quickly.
•
Sufficient aeration must be provided when work
-
ing in enclosed rooms.
• When welding and/or working with electronic
devices, make sure there is no risk of explosion.
•
Only use lifting gear which is legally defined as
such and officially approved.
• The lifting gear must be kept safely and must be
suitable for the conditions of use (weather, hook-
ing unit, load, etc.).
• Mobile equipment for lifting loads should be
used in such a way that it is guaranteed to remain
stable during operation.
