I installed two of these myself in our Charleston restoration. I'm not an electrician and had to go to You Tube to get info re: the 4" pan to accommodate the recess of the electrical connection needed when the drywall installation was a few inches below the electrical box. I studied the installation manual for a few hours because there are a lot of wires for the remote receiver. This fan is noiseless, has six settings with both downdraft and updraft. Great price!
