You may have some difficulty coaxing him down to an area he is not used to espeically if there are noises. 30 hours is a long time to not use it. When I change location of my boxes in the past I would take the kitty and put them in it and they usually jump out but it confirms where it is for them. However its never been a great distance so they always found it.
Maybe you could bring him to it and place him in it and see if he will go?? dont force the issue though because then they associate bad things with the litter box and that will not be good!

He is your friend, your partner, your defender, your dog. You are his life, his love, his leader. He will be yours, faithful and true, to the last beat of his heart. You owe it to him to be worthy of such devotion.
