→ ControlfunctionA:Openprocessvalve.
→ Usingasuitableopen-endwrench,counterthewrenchaton
the pipe.
→ Placesuitableopen-endwrenchonthehexagonofthe
actuator.
WARNING!
Risk of injury from discharge of medium and pressure.
Ifthedirectionofrotationiswrong,thebodyinterfacemay
become detached.
▶ Rotate the actuator module inthespecieddirectiononly (see
“Fig.15”).
