WARNING
Preliminary studies in females suggest that overuse of continuous spraying can increase the possibility of vaginal mucosa drying and 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.
More importantly, if you are an individual suffering from any immune defi ciency as a result of disease, chemotherapy, or other medical condition compromising the immune system you should consult your healthcare provider before use of this product.

Safety Precautions (Continued)
CAUTION
Do not pour hot water into the toilet.

Doing so may result in damage to the toilet, injury or water damage.
Do not ush anything other than bodily waste and toilet paper. Also, do not ush too much toilet paper.

Doing so may clog the toilet, causing waste water overfl ow and water damage.
If a water leak should occur, always close the shutoff valve.
When the ambient temperature is likely to drop to 0°C (32°F) 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.
When not using the Washlet over an extended period of time, drain the water out of the top unit and the water supply hose after closing the water shutoff valve, and pull the power plug from the outlet.
When using the product again, allow the product to refi ll with water fi rst.

Otherwise, the water in the tank might become contaminated and cause skin infl ammation or other problems. (Refer to Page 53 for instructions on replenishing the water.)

Leaving the power on may cause fi re or heat.
When installing the water fi lter 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, disconnect the power plug and remove the clog.

If the auto fl ush were allowed to function, it would make the wastewater in the bowl unit overfl ow and may result in water damage.

Use commercially available tools that are made for unclogging the bowl unit to remove the clogging.
Always fl ush, even after just urinating.

Failure to do so may cause inadequate fl ushing or clogging of the bowl unit, resulting in waste water overfl ow and water damage.
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 fl oor.

Ventilate the restroom to prevent condensation.
Wipe any urine, condensation, cleaner, water, etc. that has gotten on the oor with a well-wrung mop or cloth.

Failure to do so may cause staining and corrosion of the fl oor.

Safety Precautions (Continued)
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 fl at-head terminal.
Check with a qualifi ed 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 specifi c 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 confi guration as the plug.
No adapter should be used with this product. Do not modify the plug provided - if it will not fi t in the outlet, have the proper outlet installed by a qualifi ed electrician.
If the product must be reconnected for use on a different type of electric circuit, the reconnection should be made by qualifi ed 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 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 diffi cult 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 fi gure. When someone moves into the line of this infrared beam, the sensor detects the person.
Detection by the sensor may be diffi cult 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 >
When you sit on the toilet seat, the seat switch turns ON, enabling you to use various features. (A click sound is heard when the seat switch is ACTIVATED.)

Seat switch (Built-in)
Note
For prevention of damage
Wipe plastic areas such as the top unit and remote control with a soft cloth tightly wrung out with water.
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 fl oor 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.)
Dry cloth or tissue
Introduction

When a child uses the Washlet, the seat switch may not be ACTIVATED by their light body weight.

Since the toilet seat is designed to move up and down, a clearance is provided between the toilet seat cushion and the bowl unit.
