5. Setup and Installation
This wall-mounted toilet bowl requires a compatible concealed cistern and a robust wall-mounting frame (not included). Refer to the installation instructions provided with your chosen cistern and frame for specific details.
5.1 Pre-Installation Checks
- Ensure the wall-mounting frame is securely installed and level according to the manufacturer's instructions.
- Verify that the water supply and waste connections are correctly positioned and accessible.
- Check that the included hidden fixing kit components are all present.
5.2 Installation Steps (General Guide)
- Prepare Connections: Attach the waste pipe and water inlet pipe to the corresponding outlets on the concealed cistern/frame, ensuring a secure and watertight seal.
- Mount the Bowl: Carefully lift the toilet bowl and align it with the threaded rods protruding from the wall-mounting frame. Slide the bowl onto the rods.
- Secure the Bowl: Use the hidden fixing kit to secure the toilet bowl to the threaded rods. Tighten the nuts evenly until the bowl is firmly in place, but do not overtighten to avoid cracking the ceramic.

6. Operating Instructions
The Ideal Standard T459201 toilet bowl operates in conjunction with a dual-flush concealed cistern (not included). The flush mechanism is activated via a flush plate (not included) mounted on the wall.
- Full Flush: Press the larger button on your flush plate for a full flush (typically 6 liters) for solid waste.
- Half Flush: Press the smaller button on your flush plate for a reduced flush (typically 3 liters) for liquid waste, conserving water.
The RimLS+ technology ensures a powerful and thorough cleaning of the entire bowl with each flush, preventing bacteria buildup and maintaining hygiene.

7. Maintenance and Cleaning
Regular cleaning will help maintain the appearance and hygiene of your toilet bowl.
7.1 Daily Cleaning
- Wipe the exterior and interior surfaces of the bowl with a soft cloth and a mild, non-abrasive bathroom cleaner.
- Rinse thoroughly with clean water and dry with a soft cloth to prevent water spots.
7.2 Deep Cleaning (as needed)
- For stubborn stains, use a ceramic-safe toilet bowl cleaner. Apply the cleaner, allow it to sit for the recommended time, then scrub with a toilet brush.
- Flush thoroughly to rinse the bowl.
7.3 Important Cleaning Notes
- DO NOT use abrasive powders, scouring pads, or harsh chemical cleaners (e.g., bleach, acid-based cleaners) as these can damage the ceramic glaze.
- The RimLS+ design makes the bowl easier to clean as there is no traditional rim for dirt and bacteria to hide.

If you encounter issues, refer to the following common problems and solutions. For complex issues, contact a qualified plumber.
| Problem | Possible Cause | Solution |
|---|---|---|
| Weak flush | Low water pressure, partial blockage in waste pipe, cistern issue. | Check water supply valve. Inspect waste pipe for obstructions. Consult cistern manual for troubleshooting. |
| Water leaking from connections | Loose connections, damaged seals. | Turn off water supply. Tighten connections. Replace worn or damaged seals. |
