· Torque Arm Type Installation (No. 2082 Single Motor Curtains Only)
Torque arm drive assembly installation can be performed after the curtain is suspended, but if space limitations do not provide adequate
clearance when the curtain is suspended, the torque arm drive assembly must be installed prior to hanging the curtain. Regardless of when
the installation takes place, the installation procedure is identical. The instructions below cover the entire torque arm drive installation
procedure. The installer must determine when the torque arm drive installation is to take place.
Before proceeding with the assembly and installation of the torque arm drive assembly; refer to the installation drawing for mounting
location and torque arm cantilever orientation. The torque arm drive ships from the factory completely assembled, ready to install into the
batten tube, with the exception of the torque arm strap. The strap is
not routed through the spacers and not dead wrapped on the torque
arm drum at the factory. These steps must be performed later. In addition, the torque drive’s drive tube alignment is preset at the factory.
Field adjustment should not be required. To install the torque arm drive into the batten tube, align the drive tube grooves with the mating
keys of the batten tube. Gradually insert the assembly into the batten tube. While pushing the assembly into the batten tube, ensure the
torque arm sleeve grooves are aligned with the batten tube keys. Push the torque arm drive into the batten tube until the assembly is fully
seated against the batten tube end. To secure torque motor drive to batten tube, carefully drill two (2) 13/64” dia. holes approximately 180
degrees apart and 21 1/2” from the end of the batten tube. See drilling detail on Page 9.
Note: Drill through two walls only (the batten
tube wall and the outer drive tube wall)! Install two (2) pop rivets. See Figure E.
