1. Rotate the damper to its fail-safe position.
If the shaft rotates counterclockwise, mount the “CCW” side of the actuator out.
If it rotates clockwise, mount the actuator with the “CW” side out.
2. If the universal clamp is not on the correct side of the actuator, move it to the correct side for ease of installation.
3. Slide the actuator onto the shaft and tighten the nuts on the V-bolt with a 10mm wrench to 6-8 ft-lb of torque.
4. Slide the anti-rotation strap under the actuator so that it engages the slot at the base of the actuator. Secure the
strap to the duct work with #8 self-tapping screws.
