Should I install the RF28R7201SR directly next to a wall?
For optimal usage and to be able to open the refrigerator doors completely, Samsung advises not to install the refrigerator next to a wall. If installation next to a wall is necessary, allow at least 2.5 inches of clearance on the hinge side where the handle may make contact.
