Changing the light source on Modular 70

[vorgonyi]

Today my Durst Modular 70 stayed dark and I think I have to change the lamp. I bought it used but did not get a manual. On my Dunco it was easy to change the light bulb but on the Durst Modular 70 there is the housing and an additional housing for the halogene lamp. I did not find an easy way to open the housing so I think I will have to turn some screws. But which? Anyone who can help?

I found the solution and would like to post it here if anybody in the future has the same problem:

1. remove color head (b+w head or in my case Heiland Splitgrade head)
2. on the bottom of the light source head there are two screws which can be opened by hand but can only be seen from below
3. then the light source can be taken off and turned around where there is another screw which can be opened by hand. Once unscrewed the door opens and the lamp is just behind the door.

It is easy but you have to know where to look for the screws.
