Package Contents
Your AC Infinity MULTIFAN S5 package should include the following items:
- 2 x 80mm USB Fans
- 1 x Multi-Speed Controller with USB Cable
- 8 x Silicone Rubber Feet (pre-installed or separate)
- 1 x User Manual
Setup and Installation
Follow these steps to properly set up your AC Infinity MULTIFAN S5:
- Determine Placement: Identify the area on or near your electronic device that requires cooling. The fans can be positioned to either exhaust hot air away from the device or intake cooler air towards it.
- Attach Rubber Feet: If not already installed, attach the included silicone rubber feet to the corners of each fan. These feet help absorb vibrations and provide stability.
- Position Fans: Place the fans in the desired location. They can be laid flat or stood upright. Ensure the airflow direction is appropriate for your cooling needs.
- Connect USB Cable: Plug the USB connector from the fan system into an available USB port on your device (e.g., receiver, game console) or a standard USB power adapter.
- Utilize Pass-Through USB (Optional): The USB connector features an additional pass-through USB port, allowing you to power another USB device or daisy-chain up to four MULTIFAN units from a single USB source.

Operating Instructions
The MULTIFAN S5 features a convenient multi-speed controller to manage fan performance:
- Speed Settings: Use the switch on the controller to select between High (H), Medium (M), Low (L), or Off (O). Adjust the speed based on your cooling requirements and desired noise level.
- Airflow Direction: The fans can be oriented to either push air away from a device (exhaust) or pull air towards it (intake). Experiment with placement and orientation to achieve the most effective cooling for your specific setup.

Maintenance
To ensure optimal performance and extend the lifespan of your MULTIFAN S5, regular maintenance is recommended:
- Cleaning: Periodically clean the fan blades and grilles to prevent dust buildup, which can reduce airflow and efficiency. Use a soft cloth or compressed air.
- Inspection: Check the USB cable and connections for any signs of wear or damage.
Troubleshooting
If you encounter issues with your MULTIFAN S5, try the following troubleshooting steps:
- Fan Not Turning On: Ensure the USB cable is securely plugged into a powered USB port. Check the speed controller switch is not in the 'Off' position. Try a different USB port or power adapter.
- Low Airflow: Verify the fan speed is set to 'High' or 'Medium'. Check for any obstructions blocking the fan blades or grilles. Clean any dust buildup.
- Excessive Noise: Ensure the silicone rubber feet are properly installed to absorb vibrations. Adjust the fan speed to 'Low' or 'Medium' if high speed is not critical.
