Precautions during installation of pipes
Water supply pipe
●
The installation should be performed in conformity with the laws and regulations of the area where the product is to be installed.
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.
Ensure to install 3/8"pipes for water and hot water supply pipes and 1-1/2"pipes for drain 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.
The slope of the water service pipe should be determined in conformity with the laws and regulations of the area where the
product is to be installed.
Ensure that the drain pipe is installed at a gradient of 1/4" for a diameter of
φ
3.0" or less, or 1/8" for a diameter of
φ
3.0" 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.
Avoid the anchor positions when installing the pipe risers.
Equipment comes with hair catchers installed.
Be sure to take the necessary precautions to prepare for and prevent possible water leaks.
