CAUTION

Prohibited

Do not apply strong force or impacts to the urinal

Doing so may damage the urinal and cause an injury, or cause damage to property due to 
water leaking onto household belongings, etc.

If the urinal is cracked or broken, never touch the damaged parts or use the 
urinal

Doing so may cause an injury from the damaged parts. Replace at an early opportunity.

Do not pour hot water into the urinal

Doing so may damage the urinal and cause an injury, or cause damage to property due to 
water leaking onto household belongings, etc.

Do not place objects inside the bowl

Doing so may block the drainage channels and cause flushed water to overflow from the 
urinal, resulting in damage to property due to water leaking onto household belongings, etc.

Required

Wipe any urine, condensation, detergent, water, etc. that has gotten on the 
floor with a well-wrung mop or cloth

Leaving such substances on the floor may cause staining or corrosion.

Wipe off any condensation from the surface of the urinal or other parts with 
a dry cloth

Failure to do so may cause staining or corrosion of the floor.

* Ventilating the toilet with a fan or by opening a window, etc. makes it difficult for condensation 

to form.

If the urinal is clogged, be sure to close the shutoff valve before unclogging 
the urinal with a commercially available tool that is made for unclogging 
toilets

If water is flushed while the urinal is clogged, waste water may overflow and cause damage 
to property due to water leaking onto household belongings, etc.
