5. Maintenance
5.1 Cleaning
- Regularly clean the aluminum frame with mild soap and water. Avoid abrasive cleaners.
- Clean the Textilene screens with a soft brush or cloth and mild soapy water. Rinse thoroughly and allow to air dry.
- Ensure the drainage system is free of debris to prevent water buildup.
5.2 Winterization
In areas with heavy snowfall, it is crucial to prevent excessive snow load on the louvered roof. Open the louvers to allow snow to pass through, extending the lifespan of your pergola.
6. Troubleshooting
- Louvers not adjusting smoothly: Check for any obstructions in the mechanism or debris in the tracks. Ensure the crank is properly engaged.
- Screens sticking or not retracting: Inspect the screen tracks for dirt or damage. Clean the tracks and screens as per maintenance instructions.
- Water pooling on roof: Verify that the louvers are fully closed when rain protection is desired. Check the drainage system for blockages.
- Pergola instability: Ensure all frame bolts and anchor bolts are securely tightened. Re-check the installation on a flat, solid surface.
