6. Installation Guidelines
Installation of the Ivy SM-WT450 Wall Hung Toilet requires a compatible in-wall tank system and wall actuator plate (sold separately). It is recommended that installation be performed by a qualified professional to ensure proper function and adherence to local plumbing codes.
6.1 Pre-Installation Checks
- Ensure all required components (toilet bowl, concealed tank, wall actuator) are present and undamaged.
- Verify that the wall structure is adequate to support the weight of the toilet and user, as per the carrier system's specifications.
- Confirm water supply and drainage connections are correctly positioned according to the in-wall carrier system's requirements.
6.2 Mounting the Toilet Bowl
- After the in-wall tank system is securely installed and finished with wall material, attach the mounting bolts to the carrier frame.
- Carefully align the toilet bowl with the mounting bolts and push it onto the wall.
- Secure the toilet bowl using the provided washers and nuts, ensuring a snug fit without overtightening to prevent damage to the ceramic.

7. Operating Instructions
The Ivy SM-WT450 features a dual-flush system, operated by the wall actuator plate. This system allows you to choose between two flush volumes to conserve water.
- Partial Flush (0.8 gpf): Press the smaller button on the wall actuator plate for liquid waste.
- Full Flush (1.28 gpf): Press the larger button on the wall actuator plate for solid waste.
Ensure the water supply to the concealed tank is open for proper operation.
8. Maintenance
8.1 Cleaning the Toilet Bowl
- Use a soft cloth and a non-abrasive bathroom cleaner.
- Avoid harsh chemicals, abrasive pads, or cleaners containing bleach, as these can damage the ceramic surface.
- Rinse thoroughly with water after cleaning.
8.2 Removing the Quick-Release Seat
The Slymm soft-close seat is designed for quick release to facilitate thorough cleaning.
- Locate the two release buttons or tabs near the hinges at the back of the seat.
- Press these buttons simultaneously and lift the seat straight up to detach it from the toilet bowl.
- Clean the seat and the toilet bowl mounting area separately.
- To reattach, align the seat hinges with the mounting posts and press down until it clicks securely into place.

9. Troubleshooting
If you encounter issues with your Ivy SM-WT450 Wall Hung Toilet, consider the following common troubleshooting steps:
- Weak Flush: Check the water supply valve to the concealed tank to ensure it is fully open. Verify that the flush volume settings on the in-wall carrier are correctly adjusted.
- Continuous Running Water: This often indicates an issue with the fill valve or flush valve inside the concealed tank. Access the tank via the actuator plate to inspect and adjust or replace components as needed.
- Leaking: Inspect all connections for tightness. If leaks persist, consult a professional plumber.
- Loose Seat: Ensure the quick-release seat is properly clicked into its mounting posts. If the posts themselves are loose, they may need to be tightened from the underside of the toilet bowl.
For complex issues or if you are unsure about any step, it is advisable to contact a qualified plumber or Swiss Madison customer support.
