Waterproofing
• In case of the installation on the second floor or higher, waterproof the floor
appropriately.
• Drinking water (Non-drinkable well water, or water including sand or rust are not
approved for use.)
• If the water hardness is 80 ppm or more, treat the water with a water softener in
order to prevent scale clogging of the equipment.
• Set the pressure within the range from 0.08 MPa to 0.6 MPa (0.8 to 6 kgf/cm
• When the pressure exceeds 0.2 MPa (2 kgf/cm
pressure reducing valve" type.
• The cold water supply pressure must be equal to or higher than the hot water
supply pressure.
• The difference between the cold water supply pressure and the hot water
supply pressure must be 0.2 MPa (2 kgf/cm
• The temperature of hot water supply must be at least 10˚C higher than that of
hot water from the shower.
