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
deficiency 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 flush anything other than bodily waste and toilet paper. Also, do not
flush too much toilet paper.
 Doing so may clog the toilet, causing waste water overflow 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 refill with water first.
 Otherwise, the water in the tank might become contaminated and cause skin inflammation or
other problems.
(Refer to Page 53 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, disconnect 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 cause inadequate flushing or clogging of the bowl unit, resulting in waste
water overflow 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 floor.
 Ventilate the restroom to prevent condensation.
Wipe any urine, condensation, cleaner, water, etc. that has gotten on the
floor with a well-wrung mop or cloth.
 Failure to do so may cause staining and corrosion of the floor.

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.
