If you are installing a daikin FUQ71b (under solid ceiling cassette) the height is not 770mm but changed to 1010mm.
We fitted a unit within planning permissions, having submitted dimensions from a pdf brochure/tech sheet, an therefore ended up with a problem.
Hoping this helps others who may not be aware of this radical size change.
N.B. contains 2.9kg of refridgerent, for 7.1KW hardly within the spririt of the fgas legislation....
