How to use
Prepare the installation opening sized for a Ø100 mm duct and ensure the mounting surface is flat and load-bearing. Insert the grille into the duct connection and secure it to the wall or ceiling using appropriate screws or fasteners for the substrate. Connect the duct to the grille’s round spigot to ensure an airtight fit, and check alignment so the grille face sits flush with the mounting surface. After installation, verify airflow direction and seal any gaps with suitable tape or sealant if needed to prevent leaks.
Usage recommendations
For optimal performance, use the grille with ducts and fans rated for small-diameter systems and perform periodic visual inspections to keep the grille free of dust and obstructions. When installing in humid rooms such as bathrooms or kitchens, ensure compatible materials and finishes are used and consider adding a moisture-resistant sealant if required.
