Care and Cleaning
WARNING: Risk of property or product damage. Do not use in-tank cleaners in your toilet.

damage can cause leakage and property damage.

Proof
Care and Cleaning (cont.)
Kohler Co. shall not be responsible or liable for any tank fitting damage caused by the use of cleaners
containing chlorine (calcium hypochlorite).
For best results, keep the following in mind when caring for your KOHLER product:
•
Always test your cleaning solution on an inconspicuous area before applying to the entire surface.
•
Wipe surfaces clean and rinse completely with water immediately after applying cleaner. Rinse and
dry any overspray that lands on nearby surfaces.
•
Do not allow cleaners to soak on surfaces.
•
Use a soft, dampened sponge or cloth. Never use an abrasive material such as a brush or scouring
pad to clean surfaces.
•
For Artist Edition Toilets: Treat your decorative product just as you would treat your fine china.
DO NOT use bristle brushes or abrasive-backed sponges. They will scratch decorative surfaces. Use
only warm water to clean. Dry with a cotton cloth or soft sponge.

Troubleshooting
NOTE: When the remote control is not in use, it will enter standby mode. Press any key on the remote
control screen to activate the screen.
NOTE: If the back light in the window is off, the first touch on the remote control screen activates the
light. The second touch activates the function.
Start-up
When the toilet is first installed or the power fails, when power is restored or turned on the toilet
will automatically go into start-up mode.
If the toilet does not function correctly upon completing the start-up sequence, or it fails to start,
contact the Customer Care Center using the numbers located on the back page of this manual.
Blockage
To clear the toilet when there is a blockage, a standard plunger with an insert works best. Use the
remote control to open the valve before using the plunger.
If a blockage requires the use of a snake, use the remote control to open the valve before using the
snake. Close the valve when the blockage is cleared.
Small Children
The auto flush and bidet features require a sensor located under the seat to be enabled. Small
children may not be tall enough (approximately 48″ (1.2 m) to activate the sensor. The bidet and
autoflush features will not function correctly when this sensor has not been activated.
