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 electrical
current.
The plug must be plugged into an outlet that is properly installed and grounded.
DANGER - 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 flat-head terminal.
Check with a qualified electrician or serviceman if the grounding wire instructions
are not completely understood, or if in doubt as to whether the product is properly
grounded.
This product is factory equipped with a specific electric cord and plug to permit
connection to a proper electric circuit. Make sure that the product is connected to an
outlet having the same configuration as the plug.
No adapter should be used with this product. Do not modify the plug provided - if it
will not fit in the outlet, have the proper outlet installed by a qualified electrician.
If the product must be reconnected for use on a different type of electric circuit, the
reconnection should be made by qualified service personnel.
If it is necessary to use an extension cord, use only a three wire extension cord that
has a three blade grounding plug, and a three-slot receptacle outlet that will accept
the plug on the product.
Replace or repair a damaged cord.

Operational Precautions
■ For prevention of damage
● Wipe plastic areas such as the
top unit and remote control with
a soft cloth tightly wrung out
with water. Dry cloth or tissue
● Do not lean against the toilet lid.
■ Problem Prevention
● Disconnect the power plug if there is a risk of lightning.
● A toilet seat cover or a toilet lid cover cannot be used.
(The body sensors or seat switch may not function properly.)
Covers
● Do not urinate on the top unit, toilet seat or wand.
(Doing so may cause a failure or discoloration.)
● Do not apply strong forces to the control panel of the
remote control.
●
When using a toilet cleaner to clean the toilet, wash it off
within 3 minutes and leave the toilet seat and toilet lid open.
Wipe off any cleaner that remains on the bowl unit.
(If vapor from a toilet cleaner enters the top unit, it may
cause a malfunction.)
● Do not use the product with the toilet lid removed.
● Do not expose to direct sunlight.
(Doing so may cause changes in color, irregular heated
seat temperature, remote control malfunction or Washlet
malfunction due to the change in temperature.)
● Use radios, etc. away from the Washlet.
(The Washlet could cause interference with the radio
signal.)
● If you use a booster seat for infants or a soft highchair,
remove it after use.
(Keeping it installed may prevent some of the functions
from being used.)
● Do not apply force to the remote control.
(May cause malfunction.)
To prevent the remote control from being dropped, set it
in the hanger when you are not using it. Be careful not to
expose it to water.
● Do not place anything on the toilet seat and lid, and do
not press them with hands.
Failure to do so may turn on the seat switch, causing
the floor to get wet if buttons on the remote control are
touched and warm water comes out from the wand.
(The seat switch may turn on if force is applied to the
toilet seat or lid.)
■ For prevention of malfunctions
● Do not block the body sensor or the remote control
transmitter or receiver.
< About the body sensors >
Two types of body sensors are used.
●Body sensor A detects changes in heat.
 Detection may be difficult when the room temperature
exceeds 30°C (86°F), such as in the summertime.
 When sunlight is directly on the sensor area or a
heater is used in the bathroom, the sensor may
detect incorrectly due to the heat, resulting in the
automatic operation of functions such as auto lid
opening and closing.

When the bathroom door is open, the sensor may
detect people who pass to the front or side of the toilet.
●Body sensor B detects when someone stands in front
of the bowl unit.
 Body sensor B emits an infrared beam as shown in
the figure. When someone moves into the line of this
infrared beam, the sensor detects the person.
*Detection by the sensor may be difficult when the
toilet is used by someone small, such as a child.
Body sensor A
(Detects changes in heat)
Body sensor B (Detects a person
standing in front of the bowl unit.)
< About the seat switch >
