Measure And Assemble
Measure the window width and height carefully. Use a tape measure for accuracy. Check if the window frame is strong enough for the air conditioner. The unit should fit snugly without gaps.
Assemble the mounting brackets before placing the air conditioner. Attach brackets to the unit using screws provided. Ensure brackets are secure to hold the weight safely.
Install the side panels by sliding them into place. Adjust panels to fill the window gap completely. Lock them to prevent air leaks and provide stability.
Install The Air Conditioner
Position the unitcarefully in the window opening. The bottom of the air conditioner should rest on the window sill. Make sure the unit is centered and tilted slightly outside. This helps water drain away from the house. Keep the window sash down to hold the unit in place.
Secure the unit and panelsby attaching the side panels to fill the gaps on each side. Use the screws or brackets that came with the air conditioner. This stops the unit from moving or falling out of the window. Check that the panels fit tightly.
Seal gaps and insulatearound the air conditioner using weather stripping or foam sealant. This blocks air leaks and keeps your room cool. Make sure no gaps remain between the window frame and the unit. Proper sealing improves energy efficiency and comfort.

Use the remote or control panel to set the temperature. Choose the cooling, fan, or auto mode based on your needs. Adjust the fan speed to low, medium, or high.
- Check if cool air comes out after a few minutes.
- Make sure the air flows smoothly through the vents.
- Listen for any unusual noises or vibrations.
- Verify the unit turns off when you press the power button.
Proper operation means the unit cools well and runs quietly. If problems appear, check the power source and settings again.
