How to use

Prepare the duct opening or fixture to match the grille’s external dimensions and ensure the surface is clean and free of obstructions. Position the grille over the duct or aperture and secure it using suitable fasteners or clips compatible with the mounting surface. Verify that the grille aligns with the airflow direction and that the connection to the duct is sealed as needed to prevent air leaks. After installation, inspect the grille for stability and ensure that airflow is unobstructed.

Ensure mounting screws are secure and re-seal joints if air leakage is detected. When replacing an existing grille, confirm the 140×140 mm fit to avoid gaps that can affect ventilation efficiency.
