Setup and Installation
The Acekool 5000 BTU Window Air Conditioner is designed for easy installation in standard windows. Follow these steps for proper setup:
- Prepare the Window: Ensure your window is clean and free of obstructions. The unit requires a vertical clearance of at least 14.5 inches and a width between 23-34 inches.
- Attach Top Mounting Rail: Secure the top mounting rail to the top of the air conditioner unit using the provided screws. Ensure the screw hole on the rail faces outwards, as this will be used to secure the window.
- Install Accordion Panels: Attach the expandable accordion panels to both sides of the air conditioner unit. These panels are labeled "Left" and "Right" and slide into the designated guides on the unit. Stretch them out to their full length.
- Position the Unit: Carefully lift the air conditioner and place it into the window opening. Ensure the bottom lip of the unit rests securely on the window sill and the top mounting rail is positioned against the upper window frame.
- Secure the Window: Lower the window sash firmly against the top mounting rail of the air conditioner.
- Extend and Secure Side Panels: Pull out the accordion side panels to fill the remaining gap in the window opening. Secure these panels to the window frame using the provided screws.
- Apply Insulation Strips: Use the provided insulation strips to seal any remaining gaps around the unit and panels to prevent air leakage and improve efficiency.
- Install Lock Frame & Sash Lock: For added security, install the lock frame and sash lock as per the instructions in the installation kit to prevent the window from being opened from the outside.
