Never -Ever - Ever - Ever (did I say Never Ever?) lay anything with coolant on its side/back or anyother way except straight up. The oil in the compressor can flow into the cooling lines when the refrigerator is tipped onto its side or layed on its back. The oil may not completely drain from the cooling lines when tipped back up and the refrigerator may not cool. After moving, always allow atleast 24 hours of upright standing before plugging the appliance back in.
