Set up means any possible turns or cube rotations which you may need to make before you can actually pair up the f2l pair. So, for instance, if you were doing http://www.speedsolving.com/wiki/images/5/57/F2L06.png this f2l but the white was facing the back left, to set it up you would need to do a u2 before you solved the pair, assuming you solved it the way described in the wiki.
