Trying to find manufacturers instructions to see if they are properly installed at a job I am considering. They appear to be chinese import. It says they are CE but I have doubts about that. They have been installed in a ceiling that is ply with a 75mm space to the roof which is ply and insulation pushed away from the holes. As they are made of plastic I am worried they may be installed improperly in such a space hence the need for manufacturers installation instructions.
