Installing Vertical Jackshafts
| VERTICAL JACKSHAFT CONNECTED TO FACE BLADE BRACKETS |
 Ensure installed damper sections are properly installed. (See TAMCO Aluminum Damper Installation Guidelines.)
- Loosen the face blade bracket swivel fastener to allow the removal of the face blade bracket from the ¼" end rods.
- With both damper sections closed, undo the hex nuts on the drive blade U-bolts. Position the face blade bracket over the U-bolt (with the swivel at the top) and secure the bracket with the hex nuts. (For Series 9000 dampers, retain the spacing plate located in the blade channel.)
- Insert the vertical jackshaft's 5/16" diameter rod cap ends into the face blade bracket swivels. Ensuring that the damper sections are fully closed, tighten the set screws.
- If any adjustment is required, reposition the rod cap end in the face blade bracket swivel until both sections close fully.
- Retighten the swivel and verify damper closure.
- Repeat the adjustment procedure if necessary.
- If assistance is required, call TAMCO CUSTOMER SERVICE 1-800-561-3449.
