Important Information
IMPORTANT NOTICE TO INSTALLERS!: Please leave these instructions for the consumer. They contain
important information.
NOTE: This product is designed for installation with the electrical and water supplies located through the wall.
Grounding Instructions
• This product should be grounded. In the event of an electrical short circuit, grounding reduces the risk of
electric shock by providing an escape wire for the electric current. This product is equipped with a cord having
a grounding wire with a grounding plug. The plug must be plugged into an outlet that is properly installed
and grounded.
WARNING: Risk of electric shock. Improper use of the grounding plug can result in a risk of electric
shock.
• Ifrepairorreplacementofthecordorplugisnecessary,donotconnectthegroundingwiretoeitheratblade
terminal. The wire with insulation having an outer surface that is green with or without yellow stripes is the
grounding wire.
• Check with a qualied electrician or service personnel if the grounding instructions are not completely
understood, or if in doubt as to whether the product is properly grounded.

Before You Begin
WARNING: Risk of electric shock. Disconnect power before servicing.
WARNING: Risk of electric shock. Connect only to a properly-grounded, grounding-type receptacle
which is protected by a 220~240 V, 15 A, 50/60 Hz Ground-Fault Circuit-Interrupter (GFCI) or Earth-
Leakage Circuit-Breaker (ELCB). Do not remove the grounding pin or use a grounding adapter.
CAUTION: Risk of personal injury. This toilet weighs approximately 58 kg. Lift the toilet with two people,
employing proper lifting technique.
CAUTION: Risk of hazardous gases. If a new toilet is not installed immediately, temporarily place a rag
intheoorangeopening.
CAUTION: Risk of product and property damage. This toilet is not intended to be installed in buildings
where temperatures will drop below 1°C. If temperature drops below 0°C, the frozen water in tank could
