DANGER!
Risk of injury from discharge of medium and release of pressure!
It is dangerous to remove a device which is under pressure due to the
sudden release of pressure or discharge of medium.
▶ Before removing a device, switch off the pressure and vent the lines.
WARNING
Risk of injury when opening the actuator!
The actuator contains a tensioned spring. If the actuator is opened, there is a
risk of injury from the spring jumping out!
▶ The actuator must not be opened.
WARNING!
Risk of injury if the wrong tools are used!
It is dangerous to use unsuitable tools for installation work as the device may
be damaged.
▶ To remove the actuator from the valve body, use an open-end wrench,
never a pipe wrench.
