NOTE: The set screws used on all torsion winding cones and cable drums are now colored red. DO NOT identify right and left hand by the set screw color.

Slide the center bearing bracket onto the torsion tube followed by the springs and cable drums. The center bearing bracket, springs, and cable drums must be positioned as shown. With assistance, pick up the torsion assembly and slide one end of the torsion tube through one end bearing bracket and the other end of the torsion tube through the other end bearing bracket. Position the torsion tube so that equal amounts of the tube extend from each end bearing bracket.

Thread the counterbalance cable around the back side of the left cable drum and verify that there are no cable obstructions. Hook the cable into the drum. Slide the left hand cable drum against the left hand end bearing bracket and tighten the set screws in the drum to 14-15 ft. lbs. of torque (once set screws contact the tube, tighten screws one full turn). Rotate the left hand drum and torsion tube until cable is taut. Attach locking pliers to torsion tube and brace locking pliers against jamb to keep cable taut.

Repeat for right hand side.

IMPORTANT: Inspect each cable, making sure they are seated properly on the cable drums and that have equal cable tension.
