Curtain and Frame Assembly - Right Side 5304423373

This was described as a "curtain and frame assembly, right side" for an air conditioner, but no mention was made as to whether the right side referred to was on the right when facing the a/c unit or on the right when facing the back of the unit. The accompanying diagram showed the face of the a/c unit, so it seemed a normal assumption that "right side" meant when facing the unit. Apparently not, however, since what I received will only fit on the LEFT side of the unit when facing it. and Is therefore useless for me. Wouldn't it seem sensible, when faced with the potential for this sort of misunderstanding, to clearly label the diagram and its corresponding part? You want part A, you order part A; you want part B, you order part B. None of this ambiguous "right side"!
