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 pre-

vention and safety relating to the use of hazardous

products.
