2. Safety Information
Please read all safety instructions before operating this product to prevent injury or damage. Retain this manual for future reference.
- Electrical Safety: Ensure the power source matches the fan's voltage requirements (120 Volts). Do not operate with a damaged cord or plug. Avoid exposing the unit to water or excessive moisture.
- Installation: Install the fan securely to prevent it from falling. Ensure proper ducting is used to direct airflow and prevent obstruction.
- Moving Parts: Keep fingers, loose clothing, and other objects away from the fan blades during operation. The fan operates at high speeds (up to 2800 RPM) and lacks an internal safety grill, posing a potential hazard if not properly enclosed within ducting.
- Power Disconnection: In case of emergency or maintenance, always disconnect the power supply at the wall outlet before handling the fan. Note that disconnecting the controller may cause the fan to default to full power.
- Environment: This product is designed for indoor use. Do not use in explosive or flammable environments.

6. Maintenance
Regular maintenance ensures optimal performance and longevity of your CLOUDLINE PRO T4 fan.
- Cleaning Fan Blades: Periodically inspect the fan blades for dust and debris accumulation. Disconnect power before cleaning. Use a soft brush or compressed air to gently remove buildup.
- Ducting Inspection: Check ducting for any leaks, tears, or obstructions that could impede airflow.
- Sensor Cleaning: Keep the thermal-alloy probe clean and free of dust for accurate readings.
- General Inspection: Regularly check all connections and mounting points to ensure they are secure.
7. Troubleshooting
If you encounter issues with your CLOUDLINE PRO T4, refer to the following common troubleshooting steps:
- Fan Not Turning On:
- Ensure the power cord is securely plugged into both the controller and the wall outlet.
- Verify the fan to controller cord is properly connected.
- Check the controller settings to ensure the fan is not set to 'OFF' or a very low speed.
- Incorrect Temperature/Humidity Readings:
- Ensure the thermal-alloy probe is securely connected to the controller.
- Clean the sensor tip to remove any dust or debris.
- Relocate the sensor if it is in direct contact with heat sources, cold drafts, or excessive moisture.
- App Connectivity Issues:
- Ensure your mobile device is connected to a stable WiFi network.
- Restart the AC Infinity app.
- Check if the controller's WiFi indicator is active. If not, try re-pairing the device through the app.
- Excessive Noise:
- Verify that the fan is securely mounted and not vibrating against surfaces.
- Check for obstructions in the ducting or fan blades.
- Ensure ducting is properly installed and not causing airflow restrictions.
