The opening it needs

Includes the gaps Midea asks for.

Width35½″90.2 cm

Height≈69⅝″177 cm

Depth≈30¾″78.1 cm

The fridge is 29½ in wide. The 35½ in adds the 3 in of air space Midea asks for on each side
That room is for air to circulate, not part of the fridge. In a tighter space it can still slide in, but it may not cool as well
The hinges make it 66⅝ in tall, not 65⅝ in
30⅞ in deep with handles: the doors stand out past counters
