Installation and Operational Notes
- Confirm 24 VAC supply voltage before connecting the actuator.
- Mount the actuator upright on the valve body for proper operation.
- Do not exceed 5 mm stroke during valve actuation.
- Keep the system water clean to prevent valve sticking.
- Ensure actuator enclosure location meets IP40 protection requirements.
