Setup and Installation
Installation
- Ensure the toilet tank surface is clean and dry before placing the lid.
- Carefully place the TCU706CR#01 lid onto the top of the toilet tank, aligning it with the tank's edges.
- The product may include velcro tape. If provided, apply the velcro tape to the underside of the lid and the corresponding areas on the tank rim to help secure the lid and prevent accidental shifting.
- Verify that the lid sits evenly and securely on the tank without rocking.
Operation
Usage
The TOTO TCU706CR#01 lid functions as a protective cover for your toilet tank, preventing debris from entering the tank mechanism and completing the aesthetic of the toilet unit.
Maintenance
Cleaning Instructions
- To clean the lid, use a soft cloth or sponge and a mild, non-abrasive bathroom cleaner.
- Avoid using harsh chemicals, abrasive scrubbing pads, or acidic cleaners, as these can damage the porcelain finish.
- Rinse the lid thoroughly with clean water and dry it with a soft, lint-free cloth to prevent water spots.
Troubleshooting
Common Issues
- Lid Does Not Fit Properly:
Verify the model number of your toilet tank (e.g., ST706, ST743S) against the compatible models listed for the TCU706CR#01 lid. The toilet model number is typically found stamped inside the toilet tank. Ensure the lid is oriented correctly on the tank. If the lid rocks or does not sit flat, check for any obstructions on the tank rim or manufacturing inconsistencies.
- Lid Slides Off Easily:
If your lid came with velcro tape, ensure it is properly applied to both the underside of the lid and the corresponding areas on the tank rim to provide a more secure fit. Clean both surfaces thoroughly before applying the tape for optimal adhesion.
