Before you start the installation of your VELUX electric Translucent Roller Blind, please identify your windows type. If you open your roof window you'll find a data plate on top of the window either on the right or left hand side.
If you have any of the type plate information that is shown below, please use this installation guide here in PDF.
Please be aware that the pre-fitted brackets (ZOZ 230) are not included in the package. If you don't have these components on your window, you can purchase these here.
