Technical Specification:
  
1. The ideal working pressure:0.1MPa to 0.5MPa;
 
2. Cold water supply temperature:4 degree to 29 degree; Hot water supply temperature:40 degree to 85 degree;
 
3. Set the safety temperature at 38 degree;
 
4. Safety Characteristic:  If the cold water supply fails, the volume of outlet water                collected    during the first 5s shall be less than 200ml and the temperature of outlet water        shall be less than 42 degree.The volume of water collected during the second collection period   of 30s shall be less than 300ml and the outlet temperature shall not exceed 49 degree. The  temperature of the water outlet shall be at 38degree  degree after restoration of the cold water  supply;
 
5. Outlet water temperature stability: When inlet water temperature keeps stable and either of the inlet pressure for cold and hot water varies by 20%,or when inlet water pressure keeps stable(0.3MPa) and the temperature for the hot water supply increase from 55 degree to 75 degree,the temperature differential from outlet temperature to set temperature shall not exceed 2 degree;
6. Complies with the following standards:AS4032,ASME A112.18.1 2005/CSA B125.1   05,ASSE1016,EN1111 and QB2806 2006.
