- Top Rail: Attach the top rail to the unit using the provided 3/8" screws.
- Side Panels: Slide the accordion filler panels into the cabinet channels.
- Mounting: Place the unit in the window, ensuring it is tilted approximately 3 degrees downward toward the rear to allow for proper condensate drainage.

Troubleshooting
If you encounter issues, check the following:
- Unit won't start: Ensure it is plugged in, the fuse/breaker is not tripped, and the LCDI plug is reset. Wait 3 minutes for the compressor delay.
- Not cooling: Check for blocked airflow (curtains, furniture), dirty filter, or incorrect temperature settings.
- Water dripping inside: Ensure the unit is tilted slightly downward toward the rear.
