SPYDER MODEL 7 VAV CONTROLLER  INSTALLATION INSTRUCTIONS
11 31-00475-01
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.
