Attention
Please observe the following:
For the correct functioning of the actuator, the position
of the actuator must agree with the position of the valve.
Actuator open > Valve open
Actuator closed > Valve closed
When installing an actuator with a Georg Fischer ball
valve, it is important to note the position of the ball valve
spigot.
