(GFCI). Do not remove the grounding pin or use a grounding adapter.
DANGER: Risk of electrical shock. For hardwire installations/through-floor electrical supply: Connect only
to a properly-grounded, dedicated 220 VAC, 15 A, 50 Hz circuit protected by a Class A Ground-Fault
Circuit-Interrupter (GFCI) or Earth-Leakage Circuit-Breaker (ELCB).
CAUTION: Risk of hazardous gases. If a new toilet is not installed immediately, temporarily place a rag in the
floor flange opening.
NOTICE: Follow all local plumbing and electrical codes.
NOTICE: Receptacles installed in bathrooms to be located at least 1 meter from a bathtub or shower if practical,

Care and Cleaning
Kohler Company 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:
• Use a mild detergent such as liquid dishwashing soap and warm water for cleaning. Do not use abrasive cleaners
that may scratch or dull the surface.
• Carefully read the cleaner product label to ensure the cleaner is safe for use on the material.
• Always test your cleaning solution on an inconspicuous area before applying to the entire surface.
• Do not allow cleaners to sit or soak on the surface.
• Wipe surfaces clean and rinse completely with water immediately after cleaner application. Rinse and dry any
overspray that lands on nearby surfaces.
• Use a soft, dampened sponge or cloth. Never use an abrasive material such as a brush or scouring pad to clean
surfaces.
For detailed cleaning information and products to consider, visit www.kohler.com/clean.
WARNING: Risk of property or product damage. Do not use in-tank cleaners in your toilet. Products
containing chlorine (calcium hypochlorite) can seriously damage fittings in the tank. This damage can cause
leakage and property damage.
This troubleshooting guide is for general aid only. A Kohler Authorized Service Representative or qualified electrician
should correct all electrical problems. For warranty service, contact your dealer or wholesale distributor.
