6. Attach Cover: Once the frame is securely mounted, re-attach the louvered cover to the frame. Ensure it snaps firmly into place. The grille can be rotated to direct airflow as desired.

4. Operation

The AWENTA Round Ventilation Grille is designed for passive or active ventilation systems. Its operation is straightforward:

• Airflow Direction: The grille features inclining louvers. While the louvers themselves are fixed, the entire grille can be rotated within its mounted frame to direct the airflow in the desired direction (e.g., upwards, downwards, or sideways).
• Continuous Ventilation: Once installed, the grille provides continuous air passage, either for exhaust or supply air, depending on your ventilation system's setup.

5. Maintenance

To ensure optimal performance and longevity of your AWENTA Ventilation Grille, periodic cleaning is recommended:

• Cleaning: The grille is washable. Gently detach the louvered cover from the frame. Wash the cover and the integrated fiberglass net with mild soap and water. Rinse thoroughly and allow to air dry completely before re-attaching.
• Inspection: Periodically inspect the grille for any signs of damage or blockage. Ensure the fiberglass net remains intact to prevent insect entry.
• Do Not Use Abrasives: Avoid using abrasive cleaners or harsh chemicals, as these can damage the plastic material and finish.
