General Safety and Installation Instructions
Note
: The machine shall be installed in accordance with national regulations for safety and other
relevant regulations and standards.
Precautions shall be made to prevent starting of the cleaning operation, while personnel are inside the
tank or otherwise can be hit by jets from the nozzles.
In EU-countries the complete system must fulfil the EU-Machine Directive and depending of
application, the EU-Pressure Equipment Directive, the EU-ATEX Directive and other relevant
Directives and shall be CE-marked before it is set into operation.
Warning
:
If the machine is used in potential explosive atmospheres, tapes or joint sealing
compounds which are electrical insulators must not be used on threads or joints, unless
an electrical connection is otherwise established to ensure an effective earthing. In
addition, connecting pipe work, must be electrically conductive and earthed to the tank
structure. The resistance between the nozzles and the tank structure should not exceed
20,000 Ohm. This is essential to avoid the build-up of static electricity on the machine.
For further information see DS/CLC/TR 50404:2003 Safety of Machinery, guidance and
recommendations for the avoidance of hazards due to static electricity.
Electrical equipment such as magnetic valves and electric actuators must not be installed in Ex-zones
without type approval and marking, corresponding to the EX-class in question.
