4. Insert Window Slider: Insert the assembled window slider into the window opening. Ensure the hose cut-out is positioned at the top of the panel and the ends of the window slider are inserted into the window track.
5. Adjust and Secure: Adjust the slider so the assembly fits tightly in your window and insert the final bolt.
6. Add Insulation (Optional): For added insulation, install the window slider foam to the outside of the panels.
7. Install Window Kit Brace (If Necessary): Install the window kit brace to prevent the slider assembly from moving when the hose is attached.
8. Close Window and Secure: Close the window and install the included window security bracket found in the installation hardware bag.
9. Install Foam C: Cut Foam C to fit in between the window sashes.
10. Attach Exhaust Adapter: For optimal performance, install the air exhaust adapter onto the exhaust hose by rotating the adapter clockwise until the tabs click into place.
11. Connect Hose: Extend the hose from your air conditioner and attach it to the window slider, ensuring all four tabs click into place.

5. Condensate Drain Hose Setup

Proper condensate drainage is crucial for the efficient operation of your unit, especially in Dry or Heat modes.

5.1 Dry Mode Drainage

1. Remove the cover and plug from the top drain outlet.
2. Connect the supplied drain hose.
3. Secure the drain hose to a bucket or use the adapter to connect to a longer hose. A garden hose can be optionally attached to the threaded outlet.
4. Ensure the end of the drain hose is secure to prevent leaks.
5. Save the cap and plug if you wish to change modes later.

5.2 Heat Mode Drainage

1. Remove the middle drain hose cover and plug.
2. Attach the supplied drain hose.
3. Ensure the end of the drain hose is secure to prevent leaks.
4. When enough condensate is generated, the drain pump will activate and pump the condensate out. The drain pump can pump up to 6 feet above the hose connection.

5.3 Cool Mode Drainage

During Cool mode, condensate does not typically need to be drained. However, in high humidity environments, enough condensate may be generated to trigger the P1 code on the display.

• To continue operation, remove the drain cover and plug from the bottom tray and empty the condensate.
• Tip: Raise the unit and place a container under the drain before removing the cap and plug to catch any condensate.
