2 Changing the flow direction
WARNING!
Electric shock!
Before changing the flow direction, disconnect the actuator
from the power supply!
Changing the flow direction is only possible if the actuator is without current!
For changing the flow direction, proceed as follows:
1. Pull out the fastening clip.
2. Detach the actuator from the valve.
3. Turn the valve cone to the desired position.
4. Reattach the actuator to the valve and fasten by means of the fastening clip.
The flow direction can be read from the indicator on the upper side of the actuator.
