Introduction
WARNING
CAUTION
If the product is damaged, do not touch the damaged section.
• Doing so may cause electrical shock or injury. Replace it immediately
This is an electrical product. Do not install it anywhere water is likely to get on the product
or anywhere with humidity high enough that water is likely to form on the surface of this
product. When using the product in a bathroom, install a fan or ventilation port and ensure
good air flow through the bathroom.
• Failure to do so may cause fire or electrical shock.
Always connect the product to the cold water supply.
• Connecting to hot water supply may result in burns and equipment damage.
Make sure that a properly grounded (3 prong) outlet has been installed.
• Failure to install a grounded outlet could cause electrical shock in the event of a malfunction or short circuit.
Insert the power plug securely into the outlet.
• Failure to do so may cause fire, heat or short circuit.
To unplug, hold the power plug, not the power cord.
• Doing so could cause cracking or cause the toilet seat or lid to come loose and fall, resulting in injury.
• Doing so could damage the product and cause injury or water damage.
Do not lift up this product by the toilet seat or lid.
Do not raise the toilet seat or lid while objects are resting on top of the unit.
• Doing so may cause the toilet seat, toilet lid, or other parts to come loose and fall off, resulting in injury.
When maintaining the plastic parts (toilet seat, toilet lid etc.) or the water supply hose, use a
neutral kitchen detergent diluted with water. Do not use any of the following.
Toilet cleaner, household cleaner, benzene, paint thinner, powdered cleanser or nylon scrubbing brush.
• These items may damage or crack the plastic and cause injury or malfunction.
• These items could damage the water supply hose and cause a water leak.
Do not unplug by pulling the power cord.
• Pulling on the power cord may cause damage and result in fire or heat.
To prevent a sudden water leak, do not remove the water filter drain valve when the shutoff valve
is open.
If the electric cord is damaged, avoid danger by having the manufacturer’s repair
department or equivalent specialist replace it.
Do not fold or crush the water supply hose; do not damage by cutting with a sharp object.
Always unplug the power plug from the outlet before maintenance or inspection.
• Failure to do so may cause electrical shock or malfunction.
Periodically remove dust and dirt from the power plug and make sure it is securely plugged
into the wall outlet.
• Failure to do so may cause fire, heat or short circuit.
Unplug the power plug from the outlet and wipe clean with a dry cloth.
When leaking battery fluid adheres to your body or clothes, wash it away with clean water.
• The fluid may damage your eyes or skin.
Preliminary studies in females suggest that overuse of continuous spraying can increase
the possibility of vaginal mucosa drying and a potential reduction in desirable microbial
organisms.
Although these studies have not been validated, please consult your healthcare provider
for concerns regarding whether these circumstances may apply to you.
Do not apply strong force, mechanical shock, step on or stand on the toilet seat, toilet lid or
top unit. Also do not place any heavy object on the toilet seat, toilet lid, or top unit.

*1 For units with the "Photocatalyst cleaning" function only.
Safety Precautions (Continued)
DANGER To reduce the risk of electrocution:
If a water leak should occur, always close the shutoff valve.
When the ambient temperature is likely to drop to 32°F (0°C) or lower, prevent damage to the
pipes and hoses due to freezing.
• Frozen water pipes could cause the top unit and the pipes to break, resulting in a water leak.
• Regulate the room temperature to prevent the pipes and hoses from freezing during cold months.
Introduction
CAUTION
1. Do not use while bathing.
2. Do not place or store the product where it can fall or be pulled into a tub or sink.
3. Do not place in or drop into water or other liquid.
4. Do not reach for the product when it has fallen into water. Unplug it immediately.
When not using the product for a long time, close the shutoff valve, drain the water from the
top unit and water supply hose, and unplug the power plug from the outlet.
• When using the product again, allow the product to refill with water first.
Otherwise, the water in the tank might become contaminated and cause skin inflammation or other problems.
(Refer to Page 63 for instructions on replenishing the water.)
• Leaving the power on may cause fire or heat.
When installing the water filter drain valve, make sure that it is securely tightened in its proper position.
• Failure to securely tighten it may cause a water leak.
If the bowl unit is clogged, unplug the power plug and remove the clog.
• If the auto flush were allowed to function, it would make the wastewater in the bowl unit overflow and may
result in water damage.
• Use commercially available tools that are made for unclogging the bowl unit to remove the clogging.
Always flush, even after just urinating.
• Failure to do so may clog the toilet, causing waste water overflow and water damage or inadequate flushing
of the bowl unit.
Wipe condensation on the bowl unit, tank, water supply pipe and shutoff valve with a dry
cloth.
• Condensation may cause staining and corrosion of the floor.
• Ventilate the restroom to prevent condensation.
Wipe any urine, condensation, cleaner, water, etc. that has gotten on the floor with a wellwrung mop or cloth.
• Failure to do so may cause staining and corrosion of the floor.
Make sure of the plus and minus signs on the batteries before inserting them.
Remove depleted batteries immediately.
When replacing the batteries:
Replace both batteries with new ones.
Use the same brand for both new batteries (any brand available).
• Failure to do so may cause the batteries to leak fluid, generate heat, rupture, or ignite.
WARNING To reduce the risk of burns, electrocution, fire or injury to persons:
1. Close supervision is necessary when this product is used by, on, or near children or invalids.
2. Use this product only for its intended use as described in this manual. Do not use attachments not
recommended by the manufacturer.

When the product is supposed not to be used for long time, remove the batteries from the
remote control and battery box.
• Failure to do so may cause the batteries to leak fluid.
Safety Precautions (Continued)
Operational Precautions
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.
When you sit on the toilet seat, the seat sensor turns ON, enabling you to use various features.
(The deodorizer starts when the seat sensor makes a detection.)
●A label indicating the position of the seat sensor is attached to the
seat.
Detection by the sensor may be difficult when the toilet is used by
someone small, such as a child, depending on how the person sits.
Sit on the seat with the label as a guide. (The label can be peeled
off).
●Sit so your skin is in direct contact with the seat sensor. The seat
sensor may not detect properly if there is a seat cover or clothing.
●Water droplets collecting on the seat sensor may cause the main
unit to malfunction. Be sure to wipe off any water droplets on the
sensor.

(If vapor from a toilet cleaner enters the top unit, it may
cause a malfunction.)
●Do not expose to direct sunlight.
(Doing so may cause changes in color, irregular heated
seat temperature, or operation failure of the remote
control.)
●Use radios, etc. away from the product.
(The product could cause interference with the radio
signal.)
●If you use a booster seat for infants or a soft highchair,

18
This water containing hypochlorous acid generated from chloride ions in tap water, is widely used for cleaning and
disinfecting items such as food, utensils and baby bottles.
● Well water may not deliver the required effect. (Because the level of chloride ions is low.)
● "ewater+" helps to minimize dirty surfaces, but does not make cleaning unnecessary.
● The effect and duration vary depending on the usage environment and conditions.
*2 Detection by the body sensor may be difficult when the toilet is used by someone small, such as a child.
*3 Water comes out from the area around the wand for several seconds while water is warmed up.
