. Rotate the damper to its
f
ail-sa
f
e position
.
If the shaft rotates counterclockwise
,
mount the “
CC
W” side of the actuator out
.
If it rotates clockwise, mount the actuator with the “
C
W” side out.
2
. I
f
the universal clamp is not on the correct side o
f
the actuator, mount it onto the correct side
.
3. Slide the actuator onto the shaft and ti
g
hten the nuts on the V-bolt with a 13mm wrench to 11 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.
