Risk of environmental pollution due to hazardous fluid residues!
Hazardous fluid residues may harm the environment.
Handle hazardous fluid residues with care.
Temporarily place the Argus Ball Valve in the half-open position to let hazardous fluid

Ensure that unauthorized persons do not have any access to the Argus Ball Valve.
Ensure that the Argus Ball Valve is designed for the special operating conditions.
Ensure that the connections, in particular the welding parameters, comply with the
design specifications of the Argus Ball Valve.
Monitor the temperature of the valve body in the seat area by using the temperature-
sensing strips during welding.
Provide safety instructions relating the piping (including fittings).
When installing the Argus Ball Valve via flange connection determine the required
tightening torques of the bolts.
Make sure to flush the piping after the installation has been completed and before the
