Vaillant ecoFit pure

I need to top up water pressure. The two black valves are very stiff. Does anyone know which way to open valves.
Anti clockwise??? Concerned if I turn wrong way may damage.

Vaillant have a Youtube video how to refill - including arrows showing which way to turn (anticlockwise)
I have tried attaching the link, if it does not work just google "how to repressurise a Vaillant Ecotec plus".

And give the isolator valves a squirt of WD 40 and leave overnight first.
