Mount the controller
1. Back the set screws out of the drive hub until the
shaft can fit through the collar.
2. Place the controller on the damper shaft in the
approximate final position.
3. Position the anti‑rotation bracket and fasten it
using #8 or #10 self‑tapping screws. Verify the
notch in the bracket securely engages the lock tab
on the controller.
4. Manually position the VAV damper in the fully
open position.
5. Press the gear clutch button and rotate the
drive hub in the same direction that opened the
damper. Turn the hub until it reaches a rotation
limit.
6. Tighten the two set screws in the drive hub to
approximately 50–inch pounds (5.65 N•m) to
lock the hub to the shaft.
