Safety Instructions

Installation, connection, start-up, maintenance and repair work must
only be carried out by qualified personnel.
The following aspects must be observed:
- The instructions of this manual together with all relevant instructions
for the components, equipment and installations installed.
- Warnings and installations fixed to the components.
- The specific regulations for and requirements to the system in which
the valve is installed.
- The currently valid regional, national and international regulations.
- Any special requirement and national legislation relative to
the use of flammable liquids or tools, e.g. the risk of ignition
in case of spark formation, must be observed.
It must be ensured that the group, the category and the temperature
class of the valve complies with the minimum requirements of the
operating environment!
Inflammable gas mixtures or dust concentrations in connection with
hot, operational and movable parts of the valve can lead to serious
or fatal injury!
Before start of assembly the operator must make sure that an
explosive atmosphere does not exist (detection/measurement of
potential concentration of hazardous substances).
Conductive connection to the pipeline must be provided.
The integration into the internal potential equalisation must be
guaranteed!
If the valve is used for inflammable liquids, it must be observed that
every operating process is combined with an operating leakage.
This operating leakage liquid must be discharged in a closed
system.
The operator must consider this during the examination and
classification of explosive atmospheres in the outside area.
The APV CU2, CU3 and CU4 Control Units are not suited for use in
ATEX environments!
