Ensure a secure, weather-tight fit for your window cooling unit with the LG Air Conditioner Install Part Set Assembly (AET74151704). This comprehensive curtain installation kit provides all the essential components—including the left and right accordion panels, brackets, and mounting hardware—required to properly mount your air conditioner in a standard window frame. If your original side curtains are torn, missing, or no longer blocking out the outdoor heat, replacing this assembly is crucial for maximizing cooling efficiency and keeping bugs and hot air outside where they belong.

Crafted from durable, weather-resistant materials, the AET74151704 assembly is designed to expand and contract smoothly, accommodating a variety of window widths while maintaining a tight structural seal. A properly installed curtain kit not only improves the overall energy efficiency of your air conditioner but also minimizes exterior noise and vibration, ensuring your indoor environment remains quiet, secure, and comfortable.

1. Safety First: Turn off the air conditioner and unplug it from the wall outlet. If the unit is already installed, carefully remove it from the window and place it on a sturdy, flat surface.
2. Remove Old Panels: Unscrew the retaining brackets that hold the damaged accordion curtains to the sides of the air conditioner and carefully slide them out of their tracking channels.
3. Assemble the New Kit: Slide the new left and right accordion panels from the AET74151704 kit into the designated guiding tracks on the sides of the AC cabinet.
4. Secure to the Unit: Use the provided screws to fasten the curtain frames to the air conditioner chassis, ensuring the accordion material can slide back and forth smoothly without catching.
5. Install into Window: Carefully lift and position the air conditioner back into the open window. Lower the window sash firmly down behind the top mounting rail of the AC unit to hold it in place.
6. Extend and Seal: Pull the accordion curtains outward until they sit flush inside the left and right window frame channels. Secure the outer edges of the curtains to the window sill and sash using the included brackets and screws to lock the installation safely.
7. Compatible with select LG window air conditioner models, this OEM-quality installation kit provides everything you need to restore a safe, factory-standard mount.
