Setup and Installation
- Prepare the Window: Ensure the window or sliding door opening is clean and clear of obstructions.
- Adjust the Window Panel: The main plate is adjustable and can be extended to fit various window sizes, both vertically and horizontally. Slide the rail to match the width or height of your window opening.
- Install the Window Panel: Place the adjusted window panel securely into the window frame. Close the window against the panel to create a tight seal. For optimal sealing, additional weather stripping (not included) may be applied around the edges of the panel.
- Attach the Base Coupler: Secure the adaptable base coupler to the opening in the window panel. This coupler provides a universal connection point.
- Select and Attach Duct Adapter: Choose the appropriate duct adapter (4-inch or 6-inch) based on your inline fan or hose size. Fasten the selected adapter onto the base coupler. The kit is compatible with standard 4" and 6" ducting, as well as 5.1" and counterclockwise 5.9" AC hoses.
- Connect Ducting/Hose: Connect your inline fan ducting or AC hose to the installed adapter. Ensure a secure connection to prevent air leaks.

Operating Instructions
The AC Infinity Window Duct Kit functions as a passive port for air exchange. Its operation is dependent on the connected ventilation device (e.g., inline fan, air conditioner, dryer).
- Exhaust Function: When connected to an exhaust fan or dryer, the kit facilitates the removal of stale air, odors, or hot air from an indoor space to the outside environment.
- Intake Function: When connected to an intake fan, the kit allows for the drawing of fresh outside air into an indoor space.
Ensure that the connected device is operated according to its own instruction manual. The window duct kit provides the physical interface for air transfer.

Maintenance
To ensure optimal performance and longevity of your AC Infinity Window Duct Kit, follow these simple maintenance guidelines:
- Regular Cleaning: Periodically wipe down the window panel and adapters with a damp cloth to remove dust and debris. Avoid abrasive cleaners.
- Inspect Seals: Regularly check the seal between the window panel and your window frame. Reapply weather stripping if necessary to maintain an airtight connection.
- Check Connections: Ensure that all ducting and hose connections to the adapters remain secure.
- Seasonal Storage: If removing the kit for seasonal storage, clean all components thoroughly and store them in a dry, protected area.
Troubleshooting
If you encounter issues with your AC Infinity Window Duct Kit, consider the following common solutions:
- Poor Seal/Air Leaks:
- Ensure the window panel is fully extended and tightly secured within the window frame.

- Verify that the ducting/hose is securely fastened to the adapter.
- Ducting/Hose Not Fitting:
- Confirm you are using the correct adapter for your ducting (4-inch or 6-inch).
- For AC hoses, ensure compatibility with 5.1" or counterclockwise 5.9" sizes.
- Panel Not Fitting Window:
- Ensure the adjustable rail is fully extended or retracted to match your window dimensions.
- The kit is designed for most standard windows and sliding doors; verify your window dimensions against the product specifications.
