Practical help
Common problems
Ensure the grille is mounted vertically and that there is sufficient airflow from the ventilation system to push the gravity flaps open.
Check that the grille is properly sealed against the wall surface to prevent air from bypassing the duct.
Before use
- Verify the duct diameter matches the grille connection size (100 mm, 125 mm, or 55x110 mm).
- Ensure the mounting surface is flat and stable.
- Check that the gravity flaps move freely without obstruction.
- Confirm that the installation location allows for proper airflow.
