1.1 General Warnings
The manual contains basic instructions which
must be observed during installation, operation
and maintenance. The manual should be care-
fully read before installation and start-up by the
person in charge of the installation. The manual
should also be read by all other technical per-
sonnel/operators and should be available at the
installation site at all times.
Personnel Qualification and Training – All person-
nel for the operation, maintenance, inspection and
installation must be fully qualified to perform that type
of job. Responsibility, competence and the supervision
of such personnel must be strictly regulated by the user.
Should the available personnel be lacking the neces-
sary qualification, they must be trained and instructed
accordingly. If necessary, the operator may require
the manufacturer/supplier to provide such training.
Furthermore the operator/user must make sure that the
personnel fully understands the contents of the manual.
Dangers of Ignoring the Safety Symbols – Ignor-
ing the safety directions and symbols may pose a danger
to humans as well as to the environment and the equip-
ment itself. Non-observance may void any warranties.
Non-observance of safety directions and symbols may
for example entail the following: Failure of important
functions of the equipment/plant; failure of prescribed
methods for maintenance and repair; endangerment
of persons through electrical, mechanical and chemical
effects; danger to the environment because of leakage
of hazardous material; danger of damage to equipment
and buildings.
Safety-oriented Operation – The safety directions
contained in the manual, existing national regulations
for the prevention of accidents as well as internal
guidelines and safety-regulations for the operator and
user must be observed at all times.
General Safety Directions for the Operator/User
– If hot or cold equipment parts pose a danger then
they must be protected by the operator/user against
contact with people. Protective covers for moving
parts (e.g. couplings) must not be removed when the
equipment is running. Leaks (e.g. at the shaft seal) of
hazardous pumping media (e.g. explosive, toxic, hot
liquids) must be disposed of in such a way that any dan-
ger to personnel and the environment is removed. All
government and local regulations must be observed at
all times. Any danger to persons from electrical energy
must be excluded by using good installation practices
and working to local regulations. (For example VDE in
Germany).
Safety Directions for Maintenance, Inspection
and Assembly Work – It is the user’s responsibility
to make sure that all maintenance, inspection and as-
sembly work is performed exclusively by authorized and
qualified experts sufficiently informed through careful
perusal of the Operating Instructions.The accident pre-
vention regulations must be observed. All work on the
equipment should be done when it is not operational
and ideally electrically isolated. The sequence for shut-
ting the equipment down is described in the manual
and must be strictly observed. Pumps or pump units
handling hazardous liquids must be decontaminated.
Immediately upon completion of the work, all safety and
protective equipment must be restored and activated.
Before restarting the equipment, all points contained in
chapter “Initial Start-up” must be observed.
Unauthorized Changes and Manufacturing of
Spare Parts – Any conversion or changes of the
equipment may only be undertaken after consulting
the manufacturer. Original spare parts and accessories
authorized by the manufacturer guarantee operational
safety. Using non-authorized parts may void any liability
on the part of the manufacturer.
Unauthorized Operation – The operational safety
of the equipment delivered is only guaranteed if the
equipment is used in accordance with the directions
contained in this manual. Limits stated in the data
sheets may not be exceeded under any circumstances.
Cited Standards and other Documentations –
DIN 4844 Part 1 Safety marking; Safety symbols W 8,
Supplement 13; DIN 4844 Part 1 Safety marking; Safety
symbols W 9, Supplement 14
Transportation and Intermediate Storage – Pro-
longed intermediate storage in an environment of high
humidity and fluctuating temperatures must be avoided.
Moisture and condensation may damage windings and
metal parts. Non-compliance will void any warranty.
