safety instructions
danger
risk of injury due to high pressure in the installation.
• Stop the circulation of fluid, cut off the pressure and
drain the pipe before loosening the process connections.
risk of injury due to high fluid temperatures.
• Use safety gloves to handle the device.
• Stop the circulation of fluid, and drain the pipe before
loosening the process connections.
risk of injury due to the nature of the fluid.
• Respect the prevailing regulations on accident prevention
and safety relating to the use of hazardous products.
danger
risk of injury due to electrical voltage.
• Shut down and isolate the electrical power source
before carrying out work on the system.
• Observe all applicable accident protection and safety
regulations for electrical equipment.
English 23
Warning
risk of injury due to non-conforming installation.
• The electrical and fluid installation can only be carried out
by qualified and skilled staff with the appropriate tools.
• Observe mounting instructions of the fitting.
risk of injury due to an uncontrolled restart.
• Ensure that the restart of the installation is controlled
after any interventions on it.
Warning
risk of injury if the fluid pressure/ temperature
dependency is not respected.
• Take account of fluid temperature-pressure
dependancy according to the nature of the materials
the fitting is made of (see Tab. 1).
• Comply with the Pressure Directive 97/23/EC.
