Temperature 15° - 25° CHot water: Flow pressure Kpa 100 min 350 max. Temperature 55° - 60° CMinimum water flow for 100Kpa 9.377L/minIf inlet water flow pressure is higher than 350 Kpa an inline pressure reducing valve should be fittedSoil Line Hot water. Discharge temp 75° – 80° C. Soil line must comply to AS3500 Soil line connection is by a pan collar or other preferred method.
