How do I dismountable this shower screen without damaging it

[ringi]

I need to remove the shower screen so I can refit some tiles that have failed due to water getting behind them.

As I did not put up the screen I do not know how it fits together, can anyone give me some pointers on how I take it apart.

Look for self tapping screws in the corner joints if you want to fully dismantle it, but an easier way could be (with the help from an assistant or two).....
Remove the door to get the weight down; undo the screws that hold the structure to the wall (screws behind caps); slit away the silicone seal from the bottom and where it touches the wall, and very carefully lift the whole thing away complete.
