cator on the bracket represents approximately
6.5 ° of rotation per side.
The declutch button, when pressed, allows you to
rotate the universal shaft adapter.
The unit is shipped with the actuator set to rotate open
in the clockwise (CW) direction to a full 95 °. The extra
5 ° ensures a full opening range for a 90 ° damper. The
installation procedure varies depending on the damper
opening direction and angle:
1.
If the damper rotates clockwise (CW) to open,
and the angle of the damper open-to-closed is
90
°
:
a. Manually open the damper fully (rotate clock
-
wise).
b. Using the declutch button, rotate the universal
shaft adapter fully clockwise.
c. Mount the actuator to the VAV damper box and
shaft.
d. Tighten the two bolts on the centering clamp (8
mm wrench; 70 lb.-in. [8 Nm] torque). When the
actuator closes, the damper rotates CCW 90
°
to
close fully.
2.
If the damper rotates clockwise (CW) to open,
and the angle of the damper open-to-closed is
45 or 60
°
:
a. Manually open the damper fully (rotate clock
-
wise).
b. The actuator is shipped with the mechanical
end limits set at 95
° degrees. Adjust the two
mechanical end-limit set screws to provide the
desired amount of rotation. Adjust the two set
screws closer together to reduce the rotation
travel.
c. Tighten the two mechanical end-limit screws
(Phillips #2 screwdriver; (26.5-31 lb.-in. [3.0-
3.5 Nm] torque).
d. Using the declutch button, rotate the universal
shaft adapter fully clockwise.
e. Mount the actuator to the VAV damper box and
shaft.
f. Tighten the two bolts on the centering clamp (8
mm wrench; 70 lb. in. [8-10 Nm] torque).
g. When the actuator closes, the damper rotates
counterclockwise (CCW) either 45 or 60 ° to
fully close.
3.
If the damper rotates counterclockwise (CCW) to
open, and the angle of the damper open-to-
closed is 90
°
:
a. Manually open the damper fully (rotate coun
-
terclockwise).
b. Using the declutch button, rotate the universal
shaft adapter fully counterclockwise.
c. Mount the actuator to the damper box and
shaft.
d. Tighten the two bolts on the centering clamp (8
mm wrench; 70 lb.-in. [8 Nm] torque). When the
actuator closes, the damper rotates CW 90 ° to
close fully.
4.
If the damper rotates counterclockwise (CCW) to
open, and the angle of the damper open-to-
closed is 45 or 60
°
:
a. Manually open the damper fully (rotate coun
-
terclockwise).
b. The actuator is shipped with the mechanical
end limits set at 95 °. Adjust the two mechani
-
cal end-limit set screws to provide the desired
amount of rotation. Adjust the two set screws
closer together to reduce the rotation travel.
c. Tighten the two mechanical end-limit screws
(Phillips #2 screwdriver; (26.5-31 lb.-in. [3.0-
3.5 Nm] torque).
d. Using the Declutch button, rotate the universal
shaft adapter fully counterclockwise.
e. Mount the actuator to the VAV damper box and
shaft.
f. Tighten the two bolts on the centering clamp (8
mm wrench; 70 lb.-in. [8 Nm] torque).
g. When the actuator closes, the damper rotates
CW, either 45 or 60 °
,
to close fully.
