After you screw the balance tube at the top of the window, you then can charge the spiral coming out of the tube. With our 75-006 charging tool, hook it on the end pin and bring up the spiral to meet the tube. Now turn the tool clockwise about three turns. You will feel it get tighter. Now pull down the spiral and hook it in the pivot shoe. Do the same on the other side. Reinstall the sash and see if the balances hold the sash up. If the sash creeps down, remove the sash and give the spirals another turn.
