I just received the fan today and it is fantastic.  That being said, the instructions are insane.  I am going to contact Rowenta directly and request proper instructions.  This is not a cheap fan and those of us who spend our hard-earned money on it deserve the respect of proper accompanying instructions not some nondescript drawings that leave us scratching our heads and make it impossible to understand all the features of the fan, let alone access them.  Back to the fan, it is totally quiet and powerful.  I didn't want to give it 4 stars because the fan is truly a gem even if the instructions are horrible.
