A:
The RF217ACPN measures 32-1/4" wide by 68-5/8" high without hinges (69-3/4" high with hinges) by 26-1/4" deep without the doors. Samsung recommends leaving at least 2" above and behind the refrigerator as well as 1" on each side to allow sufficient air flow for the cooling system to operate properly and most efficiently. If either door will open into a wall or cabinet, you'll need at least 3-3/4" clearance on that side so the door can open at least 90º to allow the crisper drawer to open fully.
Based on these dimensions, the minimum cutout needed for this model is 34-1/4" wide (or 37" with an adjacent perpendicular wall) by about 71" high by 28-1/4" deep. The depth assumes the front edge of the refrigerator case will be aligned with the cabinet fronts.
Thanks for your interest,
Ms. Samsung
