Checking the toilet room
The dimensions required for mounting this product on a
toilet are as shown in the figure below. Check to make
sure there is sufficient space inside the toilet room and
that there are no obstructions in the way.
DANGER:Improper use of the grounding plug can result in a risk of electric hazard.
Use only the tap water line to supply water to this product. There is danger of ground water or other
water that is not tap water causing trouble with this product.
The tap water pressure must be 0.06 to 0.74 MPa (0.6 to 7.5 kgf/cm2).
This product is for use on a nominal 220 V circuit. Use a 220 V, 50 Hz power supply. The maximum
power consumption is 305 W. Electrical wiring must be installed that meets these conditions. The plug
outlet shall be placed in accessible location after installation.
This product must be grounded. In the event of an electrical short circuit, grounding reduces the risk
of electric hazard by providing an escape wire for the electric current. The power cord has a grounding
wire and a three-blade grounding plug (shown below). Do not use an adapter with the product's power
plug, or use any other method to connect the plug to an improperly configured outlet.
The outlet to which the product is connected must be 220 V, 50 Hz, with a minimum electrical rating of 3
A. The outlet must be properly installed and grounded, and have a three-slot outlet (shown below).
If it is necessary to use an extension cord, use only a three wire extension cord that has a three-blade
grounding plug. The extension cord must be rated for at least 220 V, 50 Hz, 3 A.
This product is manufactured for family or personal use. In order to avoid damage to the electronic
components, prevent the body of this product from getting wet by drops or splashes of water. In
extremely humid conditions, please provide adequate ventilation by operating an exhaust fan or opening
a window (or door).

Do not place a stove or heater close to
the body. Doing so could cause product
discoloration or failure.
If there is risk of water lines freezing,
implement the freeze prevention methods to
prevent damage. (See page 35.)
Do not apply unnecessary force to the body
water supply hose. Doing so could damage it
and cause water to leak.
Do not urinate on the nozzle. Doing so could
cause nozzle damage or failure.
In a thunderstorm, do not touch the power plug.
Doing so could cause an electrical hazard.
Do not expose this product to the direct
rays of the sun. Plastic parts could become
discolored by the sunlight.
If you are using this product for a long period of
time, set the seat temperature switch
on "Off".
For the following persons, be sure to set the
seat temperature switch on "Off" when they are
using this product.
(Children, elderly persons, persons who are
sick, persons who cannot adjust the temperature
themselves, persons with weak skin, persons
who are taking medicines that make them
drowsy, such as sleeping medications, deeply
intoxicated persons, or persons who are
extremely fatigued.)
* If this product is being used for a long
period of time with the seat temperature switch
on any setting other than "Off", there is
danger of low temperature burns.
About Low Temperature Burns
A burn occurs when the skin has been
exposed to high temperatures. However, a low
temperature burn may occur when the skin
has been in contact with an object at relatively
low temperature (about 40ºC). Susceptibility
to burns also depends on an individual’s skin
sensitivity and other factors.

A toilet seat cover or toilet seat lid cover can
cause the occupied seat sensor to either remain
on continuously or not go on at all, leading to
faulty operation. In this event, remove the cover.
While this product is still new, there may be a
slight odor when using the drying function. As
the toilet is used, the odor will disappear.
To prevent the toilet seat and toilet seat lid
from slamming down, a damping mechanism is
provided to lower them gradually. If the toilet seat
or toilet seat lid is closed roughly or too forcefully,
this product could be damaged or fail.
Sit back fully on the toilet seat and arrange your
clothing so it does not get wet when using the
wash or bidet functions.
This product is constructed to use the tap water
pressure to extend the nozzles and spray water
from them. Where the tap water pressure is
extremely low, the nozzles may not spray water
at all with the spray strength at the weakest
setting. In this case, turn the STRENGTH dial
clockwise. (See page 23.)
• The capacity of the warm water tank is 0.88 L.
Water temperature gradually drops when the
wash or bidet is used. If the water drops below
a comfortable temperature, press the stop
button and wait about 3 minutes for the water to
reheat.
• The water temperature range is preset to the
following temperatures:
Low: Approx. 36 °C,
Medium: Approx. 38 °C,
High: Approx. 40 °C.
It takes approximately 10 minutes to heat
cold water (at about 5 °C) to the appropriate
temperature (about 38 °C). Occupied seat sensor
This product is equipped with an occupied seat
sensor that prevents the water from spraying
and the dryer from operating if nobody is sitting
on the toilet seat. This prevents activation if the
wash, bidet, or dry button is pressed when the
toilet seat is unoccupied.
• You are leaning forward or sitting on the front of
the seat.
Sit back fully on the toilet seat, or change the
way you sit on the toilet.
• You are wearing clothing that is black, napped,
or otherwise inhibits light reflection.
Cover the sensor with your hand or arrange
your clothing so that your skin is sensed by the
sensor.
• Dirt or water is on the sensor.
Remove the dirt or water from the sensor.
The occupied seat sensor uses light reflection
to function and may not operate in the following
cases:
This product may interfere with radio or
television reception. In this case, move the radio
or television away from this product until the
interference ceases.
Before and after washing and when the water
temperature adjustment button is pressed, etc.,
water is sprayed out around the nozzle, but this
is necessary due to this product's construction
and is not a sign of breakdown.
If water sprays under any other circumstances,
or sprays constantly, close the water shutoff
valve and remove the power plug from the
wall outlet. Then, contact the store where you
purchased this product.
