Precaution before installation

• Secure the space required for toilet installation and at the same time, check door opening/closing for possible interference.
• The remote control signal reception may be degraded and the NEOREST unit may not respond to the remote control if there are shelves or cabinets on the rear wall at a height of less than 55-1/8”(1400 mm) from the  floor. (Shelves and storage cabinets should be more than 55-1/8”(1400 mm) from the floor.)
• 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).
• Please wash away the dust or sand in the water supply pipe completely before installing the water supply valve.
• Make sure before installation that the water supply source and water drain pipe are in the specified  position according to the diagram.
  If it is not positioned properly, the product may not be able to be installed correctly.

For water supply from the wall

Be sure to install the shutoff valve (with filter) (B-2) included with the toilet. Dirt contamination could cause shutoff or discharge defects./

Do not remove the battery box./

*The floor flange, T-bolt, and sealant are not included.

Installation procedure

*If there is a gap between the discharge pipe and floor, fill it with mold-resistant silicone-based seal material  (Mediseal).

2.

*If there is a gap between the straight pipe and the floor, fill it with the mold-resistant silicone-based seal material (Mediseal), and then attach a cover seal(B-5). Doing otherwise may cause water to leak downstairs.

Be sure to install the shutoff valve (with filter) (B-2) included with the toilet. Dirt contamination could cause shutoff or discharge defects.

8.

Ensure the wax ring does not interfere with the outlet hole. Interference could cause poor flushing performance.

•  Insert the head of the hexagonal bolt completely in the hexagonal hole of the water drain socket. If it is not inserted completely, the toilet bowl may be unstable.
•  When installing, be careful that the wire does not get pinched between the floor and discharge socket.

Insert a flat-head screwdriver or other tools into A shown in the figure to unlock and then remove the manual lever./

Mount the top unit according to the installation manual.

• It is not malfunctioning even if water flows in the toilet bowl after the water shutoff valve is opened. If electrical power is available, insert the power plug in the outlet to stop the water flow. If electrical power is not available, close the shutoff valve to stop the water. When electrical power is available, turn the unit on and then open the shutoff valve. Refer to the enclosed installation manual of the top unit.
• Confirm the operation of the manual lever. After performing a test run of the main washlet unit, confirm the operation.

Connection of the water supply hose/

Install the side panel aligned with A and B in the figure (the dotted lines), so that there are no noticeable gaps./

• After the trial-run (flush) of the toilet bowl, check the toilet bowl inside for foreign matter such as chips of cut pipe, etc. Foreign matters such as transmitted rust can stick to the sides.
• Be sure to close the water supply valve and clean the water supply filter after a trial run.
  * Remove the water supply filter using the open/close tool included with the toilet bowl or a ratchet wrench to clean the filter.
  * After cleaning the filter, open the water supply valve.
• After conducting a test run, confirm that no connections are leaking water.
  Not installing the product properly may cause water leaks that could result in flooding damage to property,  such as household belongings.
• 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.
•  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.
•  Confirm that there is no noticeable gap between the porcelain and side panel and that neither part is lifted up. If the parts are not installed firmly, the side panel could detach.

WARNING
	Do not use this product with any power supply other than the one specified. (AC 120 V, 60 Hz) • Doing so may result in heat or fire. Do not use a damaged power plug, damaged power cord, or loose socket outlet. • Doing so may result in electrical shock or fire. Do not install an outlet directly beneath a water supply location. Do not allow the water supply hose to touch the electrical outlet of the plug. • Condensation may seep into the outlet, resulting in fire or electrical shock. Do not use other water than allowed by the laws and ordinances of the region of use. Only use drinking water. Do not use seawater or recycled water. • Doing so may cause irritation to the skin and malfunction. Do not install the product on moving vehicles such as boats or RV’s. • Doing so could cause a fire, electric shock, a short circuit, or other malfunctions. • The toilet seat, lid, product main body, or another part might come loose and fall off, resulting in injury. Do not do anything that could damage the power cord, power plug. Do not strike, yank, twist, excessively bend, damage, alter, or heat any power cords. Also, do not place anything heavy on, bind, or pinch them. • Using a damaged power cord may result in a fire, electrical shock, heat, or a short circuit. Do not exceed the rated capacity of your electrical outlets or wiring equipment. • Using a single outlet to supply power to many devices by using an extension cord or other adapters may result in fire from excess heat.
	Be sure to plug the power cord all the way into the wall socket. • Failure to do so may result in electrical shock or fire. To unplug, hold the power plug, not the power cord. Do not unplug by pulling the power cord. • Pulling on the power cord may cause damage and result in fire or heat. This is an electrical product. Do not locate it anywhere water is likely to get on it. Do not locate the product in a humid environment where water may form on the surface of the product. When using the product in a bathroom, install a ventilation fan or opening, so that the bathroom has sufficient airflow to avoid extreme humidity. • Failure to do so may result in electrical shock or fire. Always connect the product to the cold water supply. • Connecting to a hot water supply may result in burns and equipment damage. Check that the product is electrically grounded appropriately. • If the ground is not installed, a breakdown or electrical current leak may result in electrical shock. *If there is no ground installed, ask the installer to put it in the ground. Confirm that wiring is connected correctly (L terminal: Live, N terminal: Neutral). • Incorrect wiring may cause mechanical failure. Always use a grounded (3-prong) electrical outlet and that is connected to a ground fault circuit interrupter (30mA or less). If the power cord is damaged, avoid danger by having the manufacturer’s repair department or equivalent specialist replace it. When installing this product, comply with the regional codes and standards on installation work. All-pole disconnection incorporated in the fixed wiring shall be provided.
CAUTION
	Do not lift the product by the toilet seat or toilet lid. • Doing so may result in the product’s main body dislodging, falling, and causing injury. Do not fold or crush the water supply hose; do not damage by cutting with a sharp object. • Doing so may result in water leakage. Do not remove the water filter drain valve while the shutoff valve is open. • Doing so will result in water leakage.
	Install the Washlet properly according to the Installation Guide. • Improper installation may result in water leakage, electric shock or fire. Push the product main body securely onto the base plate. After pushing the product’s main body until a click sound is heard, pull it slightly toward you to make sure that the product does not detach. • Not doing so may result in the product’s main body dislodging, falling, and causing injury. Make sure the plus and minus signs on the batteries are aligned correctly before inserting them. *1 • Otherwise, the batteries may leak fluid, generate heat, rupture, or ignite. When the product will not be used for a long time, remove the batteries from the remote control. *1 • Failure to do so may cause the batteries to leak fluid.
