4. Installation Instructions

5. Operation
The Sealproof Weatherproof Cover is designed for passive protection. Once installed, ensure the cover's lids are properly closed when the switch or outlet is not in use to maintain its weatherproof integrity. The GFCI section provides protection for outdoor receptacles, and the toggle switch section allows for normal operation of the switch while protected from elements.
6. Maintenance
This cover is constructed from high-impact polycarbonate, designed for durability and resistance to cracking, fading, and corrosion. Minimal maintenance is required:
- Cleaning: Periodically clean the cover with a soft, damp cloth to remove dirt and debris. Avoid abrasive cleaners that could damage the finish.
- Inspection: Regularly inspect the cover for any signs of damage, such as cracks, loose components, or degradation of the gasket. If damage is observed, replace the cover to ensure continued weatherproof protection.
- Gasket Integrity: Ensure the pre-installed gasket remains intact and properly seated to maintain the weatherproof seal.
7. Troubleshooting
- Water Intrusion: If water is observed inside the cover, check the following:
- Ensure the cover is securely mounted and all mounting screws are tightened appropriately.
- Verify the gasket is properly seated and undamaged.
- Confirm that the cover's lids are fully closed when not in use.
- Difficulty Operating Switch/Outlet: If the toggle switch or GFCI outlet is difficult to operate after installation:
- Check if the toggle switch adapter is correctly aligned and not obstructing the switch movement.
- Ensure the cover is not overtightened, which could cause distortion.
- Cover Appears Damaged or Deformed: While made from high-impact polycarbonate, extreme conditions can affect materials. If the cover shows signs of melting or significant deformation, especially in areas with prolonged direct sunlight and high temperatures, it may indicate conditions exceeding the material's heat resistance. Consider relocating the electrical box or providing additional shading if possible. Replace any damaged cover immediately.
