how to recognize potential dangers, reduce repair costs and
downtime, and increase the reliability and working life of the
product.
All personnel who work on or with the product must be
qualified for such work. The entire personnel must be of age. It
must be ensured that personnel have read and understood the
instructions in this operating and maintenance handbook. All
safety requirements and specific manufacturer’s requirements
must be fulfilled before the product is put into operation.
This manual must also be accessible to personnel at all times
and also be made available where the product is used.
1.2 Copyright
This operation and maintenance manual has been copyrighted

is intended for the use by assembly, operating and maintenance
personnel.
It contains technical specifications and diagrams which may
not be reproduced or distributed, either completely or in part,
or used for any other purpose without the expressed consent
of the manufacturer.

2 Safety
This chapter lists all the generally applicable safety instructions
and technical information. Furthermore, ever other chapter
contains specific safety instructions and technical information.
All instructions and information must be observed and followed
during the various phases of the product's lifecycle (instal-lation,
operation, maintenance transport etc.). The operator is responsible
for ensuring that personnel follow these instructions and guidelines.
2.1 Instructions and safety information
This manual uses instructions and safety information for
preventing injury and damage to property.
To make this clear for the personnel, the instructions and
safety information are distinguished as follows:
Information referring to personal injury is printed in black and
always accompanied by a danger symbol.
Danger, prohibition or instruction symbols are used as safety
symbols.
The safety symbols conform to the generally valid guidelines
and regulations, for example DIN and ANSI.
Each safety instruction begins with one of the following signal
words:
Signal word
Meaning
Danger
Serious or fatal injuries can occur.
Warning
Serious injuries can occur.
Caution
Injuries can occur.
Caution
(Instruction
without symbol)
Serious damage to property can occur,
including irreparable damage.
Safety instructions begin with a signal word and description
of the hazard, followed by the hazard source and potential
consequences, and end with information on preventing it.
Example:
Beware of rotating parts!
The moving rotor can crush and sever limbs. Switch off the
machine and let the rotor come to a rest.
2.2 Directives used
Our products are subject to local and harmonized standards.
2.3 General safety
- Never work alone when installing or removing the product.
- The machine must always be switched off before any work
is performed on it (assembly, dismantling, maintenance,
installation). The product must be disconnected from the
electrical system and secured against being switched on
again. All rotating parts must be at a standstill.
- The operator should inform his/her superior immediately
should any defects or irregularities occur.
- It is of vital importance that the system is shut down immediately
by the operator if any problems arise which may endanger
safety of personnel. Problems of this kind include:
-Failure of the safety and/or control devices
-Damage to critical parts
-Damage to electric installations, cables and insulation
- Tools and other objects should be kept in a place reserved
for them so that they can be found quickly.
- Sufficient ventilation must be provided in enclosed rooms.
- When welding or working with electronic devices, ensure
that there is no danger of explosion.
- Only use fastening devices which are legally defined as such
and officially approved.
- The fastening devices should be suitable for the conditions
of use (weather, hooking system, load, etc). If these are
separated from the machine after use, they should be expressly
marked as fastening devices. Otherwise they should be
carefully stored.
- Mobile working apparatus for lifting loads should be used in
a manner that ensures the stability of the working apparatus
during operation.
- When using mobile working apparatus for lifting non-guided
loads, measures should be taken to avoid tipping and sliding
etc.
- Measures should be taken that no person is ever directly
beneath a suspended load. Furthermore, it is also prohibited
to move suspended loads over workplaces where people are
present.
- If mobile working equipment is used for lifting loads, a second
person should be present to coordinate the procedure
if needed (for example if the operator's field of vision is
blocked).
- The load to be lifted must be transported in such a manner that
nobody can be injured in the case of a power cut. Additionally,
when working outdoors, such procedures must be interrupted
immediately if weather conditions worsen.
These instructions must be strictly observed. Non-
observance can resultin injury or serious damage to
property.
2.4 Personnel qualification
All personnel who work on or with the product must be qualified
for such work; electrical work, for example may only be carried
out by a qualified electrician. The entire personnel must be of
age.
Operating and maintenance staff must also work according to
local accident prevention regulations.
It must be ensured that personnel have read and understood
the instructions in this operating and maintenance handbook; if
necessary this manual must be ordered from the manufacturer
in the required language.
2.5 Foundations
The structural components and foundations must be of sufficient
stability to ensure safe and functional operation. The operator
or the supplier is responsible for the provision of the foundations
and their accuracy in terms of dimensions, stability and strength.
2.6 Illustrations
The illustrations used are of dummies and original drawings
of the products. This is the only realistic solution for our wide
range of products and the differing sizes enabled by the
modular system.
More exact drawings and specifications can be found on
the dimension sheet, the planning information and/or the
installation plan.
2.7 Operating procedure
Certain parts such as the rotor and propeller rotate during
operation in order to pump the fluid. Certain materials can
cause very sharp edges on these parts.
Beware of rotating parts
The moving parts can crush and sever limbs. Never
reach into the pump unit or the moving parts during
operation. Switch off the machine and let the
moving parts come to a rest before maintenance or
repair work.
2.8 Pumped fluids
Each pumped fluid differs in regard to composition, corrosiveness,
abrasiveness, TS content and many other aspects. Generally,
our products can be used for many applications. For more
precise details, see the machine data sheet and the order
confirmation. It should be remembered that if the density,
viscos-ity or the general composition change, this can also
alter many parameters of the product.
Different materials and impeller shapes are required for
different pumped fluids. The more exact your specifications
on your order, the more exactly we can modify our product to
meet your requirements. If the area of application and/or the
pumped fluid change, please inform us of this so that we can
adapt the product to the new circumstances.
When switching the product into another pumped fluid,
observe the following points:
- Products which have been operated in sewage or waste water
must be thoroughly cleaned with pure water or drinking water
before use.
- Products which have pumped fluids which are hazardous to
health must always be decontaminated before changing to
a new fluid. Also clarify whether the product may be used in
a different pumped fluid.
- With products which have been operated with a lubricant or
cooling fluid (such as oil), this can escape into the pumped
fluid if the mechanical shaft seal is defective.
