Completely read the General Installation Instructions and all other sections which pertain
to your project before starting work. These recommendations are for general erection
procedures only. For actual job conditions, see the details on the shop drawings. For
perimeter anchor types and spacing, refer to the approved shop drawings or consult the
project design professional.
Balance or Carrier Removal
8. Carefully pull down on the bottom of the balance using
a balance tensioning tool. As you pull down, pull
forward to disengage the balance from the carrier body.
Slowly, with a controlled motion, allow the balance to
retract.
9. Remove the sash stop to expose the screw in the top
end of the balance. Back out the balance attachment
screw and remove the balance from the jamb cavity.
10. With the balances out of the jamb cavity, the balance
carrier can be slid to the top of the jamb cavity and
removed.
For the upper sash of a double hung, the carrier is
removed from the bottom end of the outer jamb cavity.
11. Reinstallation would be a similar procedure in reverse
order.
Caution
Balances can be under
extreme tension.
