3. Setup and Installation
The AIRLIFT T12 fan is designed for wall-mount installation. Ensure you have the necessary tools and a suitable location with adequate space for the fan and controller.
3.1 Unpacking and Inspection
- Carefully remove all components from the packaging.
- Inspect the fan, controller, and accessories for any signs of damage. Contact AC Infinity support if any components are damaged or missing.
- Verify all included components are present: fan unit, smart controller, temperature/humidity probe, power cord, and fan-to-controller cord.
3.2 Mounting the Fan
- Choose a suitable location for the fan, typically an exterior wall of the space requiring ventilation.
- Measure and mark the opening for the fan. Refer to the specifications section for precise dimensions (15.75" x 15.75" overall, with a recommended cut-out size just under 13.5" for the flap box).
- Cut the opening in the wall.
- Secure the fan unit into the opening using appropriate fasteners. Ensure a tight seal to prevent air leakage and vibrations. Butyl glue can be used for sealing where the fan meets the wall.
3.3 Connecting the Controller
- Mount the smart controller in a convenient location, ideally near the fan or an access point.
- Connect the fan to the controller using the provided 10 FT fan-to-controller cord. Ensure the 4-pin molex connector is inserted correctly.
- Plug the temperature/humidity probe into the controller. The probe length is 12 FT.
- Connect the controller to a power outlet using the 8 FT power cord.

4. Operating Instructions
The AIRLIFT T12 is controlled by the advanced Controller 69 PRO, offering comprehensive programming options via its display and the AC Infinity app.
4.1 Basic Operation
- Power On/Off: Use the power button on the controller to turn the unit on or off.
- Manual Speed Control: Adjust fan speed manually from 1 to 10 using the controller buttons.
- Display: The controller display shows current temperature, humidity, and other settings.
4.2 Smart Programming (Controller 69 PRO)
The Controller 69 PRO allows for sophisticated automation based on environmental conditions and time.
- Temperature and Humidity Triggers: Set specific temperature and humidity thresholds to activate or adjust fan speed.
- Dynamic Fan Speeds: Program the fan to respond dynamically to changes in temperature and humidity.
- Minimum Speed Setting: Define a constant minimum speed for the fan, which will only increase when triggered by set conditions.
- Timer Mode: Set the fan to run for a specific duration.
- Cycle Mode: Program the fan to run in repeating on/off cycles.
- Schedule Mode: Set specific times for the fan to activate or deactivate.
4.3 AC Infinity App (WiFi Connectivity)
For remote access and advanced features, connect the controller to the AC Infinity app via WiFi.
- Remote Control: Operate your fan from anywhere.
- Advanced Programs: Unlock and configure more complex automation scenarios.
- Notifications and Alarms: Receive alerts for critical environmental changes or system status.
- Historical Climate Charts: View past temperature and humidity data.
- CSV Data Export: Export climate data for analysis.

5. Maintenance
Regular maintenance ensures optimal performance and longevity of your AIRLIFT T12 fan.
- Cleaning: Periodically clean the fan blades and shutters to prevent dust and debris buildup, which can reduce airflow and efficiency. Use a soft cloth or brush.
- Shutter Inspection: Ensure the steel shutters open and close freely. The IP-44 rating provides resistance to dust and liquids, but regular checks are recommended.
- Motor: The EC motor is permanently lubricated and features dual-ball bearings, requiring no user maintenance.
- Connections: Periodically check all cable connections (power, fan-to-controller, probe) to ensure they are secure.
6. Troubleshooting
If you encounter issues with your AIRLIFT T12 fan, refer to the following common troubleshooting steps:
- Fan Not Turning On:
- Check if the power cord is securely plugged into both the controller and the wall outlet.
- Ensure the fan-to-controller cord is properly connected and not reversed.
- Verify the controller is powered on.
- Fan Not Responding to Settings:
- Confirm the correct operating mode (manual, auto, timer, etc.) is selected on the controller or app.
- Check if any alarms or triggers are preventing the desired operation.
- Ensure the temperature/humidity probe is clean and correctly positioned.
