I fitted a UPV door set from Screwfix, and the instructions were very
clear about being careful the frame was square.

IIRC, it's the bed which is the most important as it supports the lot,
while the side and top fixings simply locate it - although these obviously
need to be sound.

I did take care, and mine has been fine for a number of years now.

So I'd check the bottom for level and the diagonals to look for distortion.
