Functional description for valves with manual operation
When actuating a fitting manually, the respective switching position will be locked in place in the fi-

means of a hand lever strength in a swivelling angle of 360 °.
Before operation, unlock the final position lock by lifting the notch lever against the hand lever. By
letting go of the notch lever in the respective final position the spring-loaded notch lever will latch
back by itself to the final position lock.
