The resistance of the parts that come into contact with the media depends on the media, media temperature and
operating pressure. Ensure that parts in contact with the media are chemically resistant to the dosing medium
under operating conditions!
Make sure that the pump is suitable for the actual dosing medium!
2. Safety
This manual contains general instructions that must be observed during installation, operation and maintenance of the pump. This
manual must therefore be read by the installation engineer and the relevant qualified personnel/operators prior to installation and
start-up, and must be available at the installation location of the pump at all times.
It is not only the general safety instructions given in this "Safety" section that must be observed, but also all the specific safety
instructions given in other sections.
2.1 Identification of safety instructions in this manual
If the safety instructions or other advice in this manual are not observed, it may result in personal injury or malfunction and damage
to the pump. The safety instructions and other advice are identified by the following symbols:
Warning If these safety instructions are not observed, it may result in personal injury!
If these safety instructions are not observed, it may result in malfunction or damage to the equipment!
Notes or instructions that make the job easier and ensure safe operation.
Information provided directly on the pump, e.g. labelling of fluid connections, must be observed and must be maintained in a
readable condition at all times.
2.2 Qualification and training of personnel
The personnel responsible for the operation, maintenance, inspection and installation must be appropriately qualified for these tasks.
Areas of responsibility, levels of authority and the supervision of the personnel must be precisely defined by the operator.
If the personnel do not have the necessary knowledge, the necessary training and instruction must be given. If necessary, training
can be performed by the manufacturer/supplier at the request of the operator of the pump. It is the responsibility of the operator to
make sure that the contents of this manual are understood by the personnel.
2.3 Risks when safety instructions are not observed
Non-observance of the safety instructions may have dangerous consequences for the personnel, the environment and the pump. If
the safety instructions are not observed, all rights to claims for damages may be lost.
2.4 Safety-conscious working
The safety instructions in this manual, applicable national health and safety regulations and any operator internal working,
operating and safety regulations must be observed.
2.5 Safety instructions for the operator/ user
Hazardous hot or cold parts on the pump must be protected to prevent accidental contact. Leakages of dangerous substances (e.g.
hot, toxic)must be disposed of in a way that is not harmful to the personnel or the environment. Legal regulations must be observed.
Damage caused by electrical energy must be prevented (for more details, see for example the regulations of the VDE and the
local electricity supply company).
2.6 Safety instructions for maintenance, inspection and installation work
The operator must ensure that all maintenance, inspection and installation work is carried out by authorised and qualified personnel,
who have been adequately trained by reading this manual.
All work on the pump should only be carried out when the pump is stopped. The procedure described in this manual for stopping the
pump must be observed.
Pumps or pump units which are used for media that are harmful to health must be decontaminated. All safety and protective
equipment must be immediately restarted or put into operation once work is complete.
Observe the points described in the initial start-up section prior to subsequent start-up.
Warning
Electrical connections must only be carried out by qualified personnel!
The pump housing must only be opened by personnel authorised by Grundfos Alldos!
