Before aligning the cells, the player should have already opened the water gate on the prison's roof to let light flow in. Henry Townshend must rotate the 2nd and 3rd floors in such a way that all three floors become aligned so that he can jump through the holes in each one and reach the prison's cafeteria. Henry can check current alignments through peepholes located in the central shaft after he turns the valves. As indicated by a memo found earlier, all he has to do is align the cells with bloodied beds one on top of the other. As noted, all bloodied-bed cells have holes in them. If a cell has blood in it but no blood on the bed, ignore it.
