Short Shaft Installation
I
f the shaft extends at least 3/4” from the duct, follow these ste
p
s
:
1
. Determine the best orientation
f
or the universal clamp on the back o
f
the actuator.
T
he best location would be where you have the easiest access to the V bolt nuts on
t
he clamp
.
2. Engage the clamp to the actuator as close as possible to the determined location
.
3
. Lock the clamp in place using the remaining retainer clip.
4
. Verify that the damper is still in its full fail-safe position
.
5. Slide the actuator over the shaft.

. Slip the stud of the anti-rotation strap into the slot at the base of the actuator.
T

1/16 of an inch from the closed end
of the slot. Bend the strap as needed to reach the duct. Attach the strap to the
