This is the instruction manual for the Aqua Venus tourmaline ceramic ball product, used in baths. The main points are as follows:
How to Use: Rinse the main unit and then place it in the bathtub. It is effective to leave it in the tub if you have a 24-hour bath or a reheating function.
Care: Approximately once a month, rinse with water or lukewarm water, and dry in the shade or in the sun for about 2 hours.
Removing the Back Panel: Refer to the diagram and use a Phillips screwdriver to remove the panel.

About Handling
Thank you for purchasing Aqua Venus. We hope you will continue to patronize us for many years to come.
How to Use
Before use, soak the main unit in fresh or lukewarm water, rinse (shake) in water, and then place it in the bathtub.
Some fine powder from the surface of the tourmaline ceramic balls may come off during rinsing, but it is harmless, so please do not worry.
For those using in a 24-hour bath or a reheating bath, it is more effective to leave it in the bathtub except during cleaning.
Care Instructions
Approximately once a month, soak in fresh or lukewarm water, rinse thoroughly, and dry in the shade or in the sun for about 2 hours. (This measures the activity of tourmaline and ceramics.)
When not in use for a long period, store after performing the above care.
This product uses 304 stainless steel, so it will not rust if used correctly.
How to Remove the Back Panel
Refer to the diagram and remove the screws in the center of the rubber packing with a Phillips screwdriver. There are 4 rubber packings and screws.
