While the document is not too complicated, the difference with a normal mixer is that you have 3 instead of 2 water outlets (2 cold and hot) you can mount it differently, but it's more complicated because it takes adjust the temperature .So it is the 3rd exit to the touch, you have left room behind the sink in because there are electrical block for touch (he says 6 cm from the wall but you need more to work properly ) else frankly, it is too good !!! and then one feels the quality on, Do NOT FORGET YOU MUST CONNECT YOUR EARTH ELSE YOU WILL KEEP YOUR GLUE MIXER !!! great design in all cases.
