CORD REEL ASSEMBLY
12. TORQUE ARM BELT TIE-OFF (No. 2082 Curtains Only)
The torque arm belt is attached either to the overhead steel or to a provided cantilever arm weldment. Regardless of attachment, the
position of the belt tie-off is critical. The belt must be attached directly above (preferably above the curtain attachment height) and in line
with the outer edge of the torque arm roller. See installation drawing for specific details.
Before proceeding with the belt attachment, verify the number of dead wraps on the drum. A minimum of two (2) wraps is required.
Next, wrap belt around the tie-off and secure with the provided belt buckle. Refer to the detail below for proper attachment. Trim excess
belt length.

13. CORD REEL ELECTRIC CONNECTION
Before the cord reel assembly can be used, it is necessary to pre-tension the reel assembly’s spring. This is accomplished by performing
the following: when facing the outer flange of the assembly, with the cord wound on the drum, rotate the reel and cord together no more
than two (2) revolutions in a clockwise direction. Now, without releasing the tension, pull the retractable cord down to counter-torque
assembly’s junction box. Ensure that the reel cord is in line with the junction box and counter-torque assembly.
Caution: Do not allow
the cord to retract without restraining the retraction speed. Doing so can damage the spring motor, and may cause improper cord
operation.
Connect the cord to the top junction box knockout using the provided SJO cord connectors and conduit locknuts. Inside the
junction box, tie a loose knot in the cord to prevent the cord from pulling out of the junction box. Hand tighten the SJO cord connector
friction nut until it grips the cable securely. See Figure G.
