A:Answer Thanks for your interest. Samsung recommends leaving at least 3/8" clearance on the top and each side of the RF28HFEDBSR, and 1" behind it for air circulation. If either side is opening into a wall, additional space is needed to allow the handle to clear (approximately 3-3/4" for the door to open 90 degrees). This would make the minimum size of the enclosure 36-1/2" wide by 71" high by 30" deep if you want the refrigerator to be recessed into the cutout as far as the front edge of the case. The 71" height is based on providing space above the 70" door hinges to allow for leveling, but may not be necessary depending on your flooring. If the cabinets above the fridge are 24" deep or less, then the minimum height would be 69-1/4".
