You just screw it into the UV/IR filter. If I am doing something that doesn't involve synthetic blacks, I don't bother with the UV/IR, as I've noticed a little reflection problem from the filter when the angle of the light source is in a certain position in relation to the lens.By having the IR filter on, how do you attach the polarize to the IR filter, I think I am missing some thing.
