Installation of pipes
The following are important points to adhere during the installation of pipes.
Read through the details carefully and ensure that the pipes are installed correctly.
When installing this product, ensure that installation of pipes adheres to the instructions outlined in "Precautions during
installation of pipes". Installing pipes without reading through the precautions will mean water may not mix properly, and a set
temperature will not be achieved.
This product is designed for indoor installation. Always install this product indoors.
Precautions during installation of pipes
Do not use pipes made of materials that may introduce rust for the water supply pipe.
In general, VP pipes or other materials specified by regulations in that particular region, are recommended for installation.
In general, Type L deoxidized copper pipes are recommended for hot water pipes.
In general, the same diameter and same pressure is recommended for hot water pipes and water supply pipes.
Always use a reamer to deburr the ends of cut pipes.
Avoid using inverted U-shaped pipes (siphon) as these can cause air to become trapped.
Always connect hot water pipes and water supply pipes after removing all contaminants such as dirt, sand and oil as these can
cause problems.
After connecting the pipes and testing water flow, clean the filter and shower head.
Ensure that the drain pipe is installed at a gradient of 1/50 for a diameter of φ75 or less, or 1/100 for a diameter of φ75 or more.
Do not connect the hot water pipes and water supply pipes in reverse.
Connecting pipes in reverse will mean the temperature of water cannot be controlled properly by the water taps, which can
cause problems including burns.
Ensure that the hot water pipes from water boilers are only run over a short distance so as to minimize resistance.
Longer pipes can cause fluctuations in temperature and poor hot water delivery.
Always wrap pipes with lagging material after installation is complete.
Water boiler pipes
● In general, the same diameter and same pressure is recommended for main hot water pipes and main water supply pipes.
● Ask professional to install water boiler.
Equipment comes with hair catchers installed.
Avoid the anchor positions when installing the pipe risers.
Floor surface
Ensure that the material or finishing of the floor surface is waterproof or has a waterproof coating applied.
Always ensure that the floor surface is horizontally level.
Ensure that the floor surface is smooth and free from bumps around the attachment areas.
Be sure to take the necessary precautions to prepare for and prevent possible water leaks.

○Contents of defect
①Something wrong with hot water（Temperature is unstable）
②Hot water（high temperature）does not come out
③Water（low temperature）does not come out
○Presumed cause
①There is difference in the water supply or hot-water supply pressure,
or the pressure of hot water supply is higher than the pressure of water supply.
the pressure of water supply ≧the pressure of hot water supply
[ The difference should be in the range of 0.2Mpa ]
②Pressure of water supply and hot water supply is high
[ These two should be in the range between 0.1 and 0.4MPa ]
○How to react
Connect a pressure reducing valve (Optional) on the upper side (mixer side)
of the filtered check valve, then adjust the pressure.
(It is recommended that water supply pressure and hot water supply
pressure become the same pressure）

water is 20℃and hot water is 60℃)
(1) Is there no water leaking from the pipe joints?
The pipe joints may come loose during transportation,
so check the joints within the basin thoroughly.
(2) Are the hot water supply and water supply pressures
at the same, stable pressure?
If the pressure is not the same, see "How to adjust faulty
temperature regulation" below.
(3) Can temperature be controlled properly?
(4) Check that the shower outlet flow is sufficient,
by the following as a guide for flow rate.
