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.
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.

NOTE
Risk of damage to the device due to the environment
▶ Protect this device against electromagnetic interference,
ultraviolet rays and, when installed outdoors, the effects
of the climatic conditions.
To make sure the device operates correctly, plug in
and tighten the connector.
Installation of the fitting onto the
pipe
→
Choose a fitting appropriate to the velocity and the flow
rate of the fluid inside the pipe, refer to the graphs at right
(see Table 2). The graph is used to determine the DN of
the pipe and the fitting appropriate to the application,
according to the fluid velocity and the flow rate.
→
Install the fitting on the pipe as described in the operating
instructions of the fitting used.

WARNING
Risk of injury if the fluid pressure/ temperature
dependency is not respected.
▶ Take account of fluid temperature-pressure dependency
according to the nature of the materials the fitting is made
of (see Table 1).
▶ Comply with the pressure equipment directive 2014/68/EU.
WARNING
Risk of injury due to non-conforming commissioning.
Non-conforming commissioning may lead to injuries and
damage the device and its surroundings.
▶ Before commissioning, make sure that the staff in
charge have read and fully understood the contents of
the manual.
▶ In particular, observe the safety recommendations and
intended use.
▶ The device / the installation must only be commissioned
