If the shaft extends at least 3/4” from the duct, follow these
steps:
1. See Figure D. Move damper blades to the fail-safe position (a).
2. Determine the best orientation for the universal clamp on the
back of the actuator. The best location would be where you
have the easiest access to the V bolt nuts on the clamp.
3. Engage the clamp to the actuator as close as possible to
the determined location.
4. Lock the clamp to the actuator using the retainer clip.
5. Mount the spring return actuator to the shaft. Tighten the
universal clamp, finger tight only.
6. Mount the anti-rotation strap at the base of the actuator. Do
not tighten the screws.
7. Remove the screw from one end of the mounting bracket
and pivot it away from the actuator.
8. Loosen the universal clamp and, making sure not to move
the damper shaft, rotate the actuator approximately 5° in
the direction which would open the damper.
9. Verify that the damper is still in its full fail-safe position.
10. Tighten the universal clamp to the shaft.
11. Rotate the actuator to apply pressure to the damper seals
(b) and re-engage the anti-rotation strap (c).
12. Tighten all fasteners.
13. Use IND-TF accessory if position indication is needed.

Remounting the Stroke Limiter
1. Remove the stroke limiter
by inserting a small
screwdriver, like the one
shown, and gently prying
upward. This procedure
takes very little force.
See Figure 1.
2. While holding the back eye-let, unscrew the end-stop so
that eye-let separates from the end-stop.
3. Flip the limiter over, so
the teeth point the other
direction. Replace the
eye-let and end-stop.
4. Flip the actuator over to
the opposite side (this
reverses the spring
return direction of the actuator). Replace the stroke limiter
assembly by inserting the first two teeth as shown in the
orange circle. Then press the stroke limiter into place by
pushing downward on
the adjustable stop.
5. Replace clamp and
retaining clip.
