Material
The main body of multifunction thermostatic concealed shower valve uses HPb59-1(grade A brass).
Zinc alloy made faucet handwhell is anti-oxidation and corrosion-resistant.
The HPb59-1 panel is anti-oxidation and corrosion-resistant.
Due to the use of copper, this thermostatic cartridge is able to inhabit the growth of the bacteria.

Operating conditions:
1. The optimum working pressure is 0.5-5Bar, we recommend a pressure-increasing valve be installed when the pressure is lower than 0.5Bar.

2.The outlet temperature of the cold water is 4℃-25℃and the hot water is 55℃-85℃.

3.The safety temperature is set at 38℃(±2℃).

4.Anti-scald: While the cold water supply fails, during the first 5 seconds (±0.5 seconds) if the outlet water volume is less than 200ml, the outlet temperature is within 49℃, otherwise the temperature should be less than 42℃ and the volume be less than 300ml, the temperature will be less than 49℃ in the following 30seconds. Besides, the temperature difference between the outlet water and the set temperature should not exceed within 2℃.

5. Stable outlet water temperature: when the inlet water temperature is stable and the inlet pressure is 0.3 MPa, then either pressure of the cold or hot water reduces by 20%; or when the inlet pressure is 0.3 Mpa, then the inlet temperature of hot water varies by 10%, eventually the outlet water temperature difference is within 2 ℃ compared with the set temperature.
