We have the 2009 model and in the first month I installed 4 selective valves that allows us to open individule slides at choice.
Just added the Hydraulic Diagram. Bought 10ft and 20ft hose.
Now I realised that my drawing shows the wrong hose connection on the cylinders, I connected all the return lines as required by Limpert to the valves.
Update:
I have now updated to the as build hydraulic diagram on my Unit.
