Setup, Compatibility & Care
Installation
This model is designed for roof pitches between 15° and 55°. If your roof exceeds 55°, you must purchase the optional spring accessory kit to extend compatibility up to 75°. Given the weight and mechanics of top-hung windows, professional installation is strongly recommended to ensure correct alignment and weather-tight sealing.
Care and Maintenance
- Cleaning the Frame: Use a soft, damp cloth with mild detergent to wipe down the polyurethane frame. Avoid abrasive cleaners that could scratch the finish.
- Glass Maintenance: The external pane can be cleaned by rotating the sash 180 degrees and locking it in place with the barrel bolt, allowing safe access from inside.
- Ventilation Filter: Periodically remove and wash the ventilation air filter located behind the top control bar to maintain optimal airflow.
