responsibility of the operator to make sure that the
contents of this manual are understood by the
personnel.
2.4 Risks when safety instructions are not
observed
Non-observance of the safety instructions may have
dangerous consequences for the personnel, the

Non-observance of the safety instructions may lead
to the following hazards:
•
failure of important functions of the pump/system
•
failure of specified methods for maintenance
•
harm to humans from exposure to electrical,
mechanical and chemical influences
•

2.10 Safety of the system in the event of
a failure in the dosing system
DDI 209 dosing pumps are designed according to
the latest technologies and are carefully
manufactured and tested. However, a failure may
occur in the dosing system. Systems in which dosing
pumps are installed must be designed in such a way
that the safety of the entire system is still ensured
following a failure of the dosing pump. Provide the
relevant monitoring and control functions for this.
Warning
Electrical connections must only be
carried out by qualified personnel!
The pump housing must only be
opened by personnel authorised by
Grundfos!
