*The product may be slightly different in shape than the product shown in the figure depending on the model.
Secure the space required for toilet installation and at the same
time, check door opening/closing for possible interference.
Turn on electricity and water supply to the product after
completing all installation work.
Use care not to damage the end of the connection hose.
The minimum required water pressure (flowing) is 7PSI at
2.64 Gal/min (0.05MPa at 10 L/min) while the maximum
water pressure (static) is 108PSI(0.75MPa).
Make sure before installation that the water supply source
and water drain pipe are in the specified positions
according to the diagram.
If it is not positioned properly, the product may not be
able to be installed correctly.
Please wash away the dust or sand in the water supply
pipe completely before installing the water supply valve.
If there is a gap between the discharge pipe and floor,
fill it with mold-resistant silicone-based seal material
(Mediseal).
Doing otherwise may cause water to leak downstairs.

Caution in handling of the Sealant
Required
Caution

1. Do not pour detergent into the tank. Doing so could cause damage to the household
or product. Detergent that contains fluorine components (calcium hypochlorite)
could damage devices inside the tank. Resulting malfunctions such as water shutoff
problems could cause water leaks that could result in flooding damage to property,
such as household belongings.
2. All materials are written based on the latest product conditions at the time of
printing. However, TOTO China reserves the right to change product specifications,
packaging, or supply conditions at any time.
We may change this without prior notification.
3. Installing this product with cement is prohibited. TOTO shall not be held responsible
for any damage to toilets caused by cement installation.
4. Use only the included discharge connection parts. If the building's plumbing uses a
trap structure, it could impact the flushing performance of the product.
Caution: If any other issue occurs during use, contact the TOTO After
Sales Service Department.
Malfunction 5: Water leaks from the tank.
1. If the water in your region is of a hard quality, clean the toilet with toilet cleaner at
least once per week. This will keep the water discharge outlet clean and the toilet
flushing properly. Use a long brush to clean inside the water discharge outlet and
water passage. This can prevent mineral matter from accumulating. Although most
detergents will not damage the surface of the toilet, be sure to follow the detergent
manufacturer's instructions when cleaning. Do not use corrosive chemicals or liquids.
2. Do not flush newspaper, diapers, sanitary products, or other foreign matter down
the toilet. Doing so could clog the toilet pipeline.
3. Do not subject the toilet to strong forces or impacts. Otherwise, the toilet may break,
causing injury or leaks that may damage property.
4. Do not use this product in environments subject to temperatures of 0° or below.
5. When you first use the product, slowly open the shutoff valve and confirm that there
are no water leaks between the water supply hose and tank unit, and between the
water supply hose and shutoff valve connection area.
6. Adjust the water level if the water level inside the tank is lower than the standard
water line (WL). Otherwise, flushing performance will be affected (refer to Figure 2).
7. If the water pressure is high, tighten the shutoff valve appropriately to prevent the
shutoff valve and hose from disconnecting.

• After installation, unseen dirt (oil or adhesive for piping) may remain in the
toilet bowl.
Be sure to wipe it off using a non-abrasive neutral detergent for toilets.
Otherwise, the toilet bowl surface may not flush completely clean.
• Make sure that there are no scratches or other damage on the ceramic
surface.If the ceramic surface is tightly pressed or rubbed against metals
(watchbands, belt buckles, etc.), black or silver streak marks may be left
on the surface.
