Change-over Valves are linked to each other with a chain. This allows for
synchronised switching of the Change-over Valves.
Procedure
1. Position the discs of the Change-over Valves to be connected to the very
left or the very right.
2. Turn the handwheel of the Change-over Valve at the outlet side back by
approx. 160°.
3. Place the chain on the two chain wheels, shorten it to fit the distance
between the Change-over Valves and close the chain lock.
