○Water supply (primary) plumbing
・In the case of using city water direct pressure line, consult to local contractors designated by the water supply
Works Department. Installation must be made in compliance with the plumbing code requirements such as the
"Water Supply Works Department Installation Standard", etc. in your area.
・In the case of using lines other than the city water line (fall supply line from elevated water tank), consult to local
contractors designated by the water supply Works Department. Installation must be made in compliance with the
plumbing code requirements such as the "Water Supply Works Department Installation Standard", etc. in your area.
○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 demurred 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 Drainpipe 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.
○Plumbing particulars for water heater
・In general, the same diameter and same pressure is recommended for main hot water pipes and main water supply pipes.
・Contact a professional for installation of water heater.
○Equipment comes with hair trap installed.

■CAUTIONs During Installation Of Pipes
・Public water supply
(do not use non-drinkable well water or water that contains rust or sand.)
・If the water hardness is 80 ppm or higher, install a water softener to prevent the buildup of scale.
Aeration may be minimal when using shampoo even if drinkable well water is used, so a water
softener should be installed.
・Use a pressure set between 0.1 to 0.4 MPa (1 to 4 kg f/cm2).
If multiple YUME OASIS are used, ensure that the pressure does not drop below 0.1 MPa (1 kg f/cm2).
・Set the water supply pressure ≧hot water supply pressure.
・Set the difference between the hot water supply pressure and water supply pressure to within
