1 Verify that the valve
is open.
2 Slide the actuator straight
down over the valve shaft
and onto the mounting
plate.
3 Align the actuator with the
mounting plate, then slide
the anti-rotation clip half
way into the slot on the
bottom of the actuator.
4 Tighten the wing nut to secure
the anti-rotation clip in place.
Be careful not to over-tighten
the wing nut.
5 Secure the actuator to the valve shaft:
a. Verify that the actuator’s position indicator is pointing to
the 0° position. If it is not, slide and hold the manual
release slider on the actuator housing to disengage the
gears, and then use the positioning lever to turn the
actuator’s output shaft to the 0° position. When finished,
release the slider or button to re-engage the gears.
b. Using a 3 mm hex wrench, tighten the setscrew,
applying 55 to 60 lb-in. (6.2 to 6.8 N-m) of torque.
