The opening it needs

Includes the gaps Midea asks for.

Width≈26⅜″67.0 cm

Height≈50 13/16″129 cm

Depth≈24⅛″61.2 cm

The fridge is 18½ in wide. The 26⅜ in adds the 3 15/16 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
Next to a wall: leave 3 15/16 in on the hinge side
