Assemble The Air Conditioner
Before installing your Frigidaire air conditioner in a window, you need to assemble its parts. This step ensures the unit fits properly and works well.
Follow the instructions carefully. Take your time to avoid mistakes that can cause air leaks or damage.
Attach Side Panels
Side panels help fill the gaps on each side of the air conditioner. They make the unit fit the window securely.
To attach the side panels, slide them into the grooves on the sides of the air conditioner. They should move smoothly but stay firm.
- Check that the panels are the right size for your window.
- Slide one panel on each side of the unit.
- Adjust the panels to fully cover the open space.
- Make sure the panels lock or click into place.
Secure Sealing Strips
Sealing strips prevent air leaks and keep the unit stable. They also block dust and insects from entering.
Attach the sealing strips along the edges where the air conditioner meets the window frame. Press them firmly to stick well.
- Use the sealing strips included with your air conditioner.
- Place strips on both the inside and outside edges.
- Press tightly to ensure a good seal.
- Check for any gaps and fill them with extra strips if needed.
Position The Air Conditioner
Placing the air conditioner correctly in the window is important for its performance. A good position helps the unit work efficiently and keeps your room cool.
