How to tension 30" spiral balance

Question

Hello,

Wondering how many clockwise turns I make to properly tension a 30" series 400 spiral balance, or is there some other way to know when it is properly tensioned? First time doing this repair.

Thanks

Have someone hold up the sash as high as they can. Now you bring up the spiral as close as you can to the sash. Next, hook on the charging tool, our 75-004, and turn the spiral clockwise three turns. You should feel the tension building as you turn. Do both sides and try the sash. If it slides down, raise the sash and give it another turn. I hope you have found this information useful.
