To mount the Neptronic ST080S Actuator on a round or square shaft, follow these steps:
1. Manually close the damper blades and position the actuator at 0º or 90º.
2. Slide the actuator onto the shaft.
3. Tighten the nuts on the "U" bolt to the shaft using an 8mm wrench to a torque of 60 in.lb. [6.7 Nm].
4. Slide the mounting bracket under the actuator, ensuring free movement of the slot at the base of the actuator. The bracket pin must be placed in the mid-distance of the slot.
5. Fix the bracket to the ductwork using #8 self-tapping screws.
Please refer to the Neptronic ST080S Actuator Instruction Manual for further details and illustrations on the mechanical installation process.
