ALL front loaders will require the use of High Efficiency Detergent and ALL front load washers are Energy Star qualified. Some may use less energy than others, but they are all included in the Energy Star Category.

first thing's first, you have to have your water shut off before the delivery drivers will unhook the existing refrigerator (or you can unhook it yourself). the best thing to do is to get a NEW stainless steel waterline that will run from the back of the refrigerator to the wall. old ones from existing refrigerators can gunk up and make your water taste awful, not to mention, if there's corrosion to the old one, it can bust and cause you not to be able to use your refrigerator's ice and water until a new waterline is purchased.

as far as precaution goes, the drivers will make sure your water is turned off before installation so they don't damage your hardwood. ALSO, they'll take special considerations with getting the product into your home and not scratch your floor.

just call your local best buy and ask an appliance specialist of all the details!
