If the order is wrong and he activates it than it's accepted as correct.
the irds and programming choices are considered correct if he activates it, but I cant imagine those irds would even pass iv if you do indeed have the mandarin package on your account? Let him try to install it, he'll fail iv, realize he needs a legacy lnb and swm 8. If he leaves and its not working call in and it will create a FSR on him (hate to encourage this but it might be necessary). 1 bad installer shouldnt keep you waiting til summer to watch your programming
