【Easy Installation】 - 1. Open the sliding window approximately 20 cm and place the seal on the window frame. 2. Position the sealing strip along the edge. 3. Pass the drain hose through the round opening. 4. Tighten the cord lock and secure the hose with the included Velcro strip to complete the installation. No drilling is required; it's very simple.

【Tips】 - 1. Clean the dust from the window frame before applying the adhesive. 2. It is best to wait 24 hours after installation before use.
