Description:  An automatic Thermostatic Valve can be used in supporting electric water heaters and solar water heaters, the user can adjust their own hot and cold water temperature.    Usage:  1. Constant temperature Mixer system developed supporting products,     widely used in electric water heaters, solar water heaters and geothermal heating water system.  2. And can be used in supporting electric water heaters and solar water heaters, the user can adjust their     own hot and cold water temperature, the required temperature can quickly reach and stabilize.  3. To ensure that the water temperature is constant, and from the water temperature, flow, water pressure     changes, to solve the bath center temperature hot and cold problems.  4. When the cold water is interrupted, the Mixer within a few     seconds, play a security role.    Working principle:  At the Mixerature Mixermal element is provided to promote the movement of the valve body in the valve body, to block or open the inlet of the cold and hot water. In the closure of cold water at the same time to open the hot water, when the temperature adjustment knob set a temperature, regardless of cold, hot water inlet temperature, how to change the pressure into the outlet of the cold, hot water ratio also changes, so that The water temperature is always constant, the temperature control knob can be set within the product temperature range, constant temperature Mixer temperature.    Specifications:  Color Silver and Black;  Size Approx. 9x3.5x2cm/3.54"x1.37"x0.78";  Working pressure 0.03-1 (Mpa) (MPa);  Outlet flow 0.7 (m3 / h);  Cold water temperature 5-29 (℃);  Hot water temperature 50-90 (℃);  Temperature control accuracy ± 2 ℃;  Diameter DN15 (mm);  Weight 357g;    Installation:  1. The red mark is hot water imports. The blue mark is cold water imports.  2. Set the temperature, such as water temperature or pressure changes, the water temperature changes in     the value of ± 2oC.  3. If the hot and cold water pressure is inconsistent, should be installed in the inlet one-way check valve to     prevent cold, hot water string.  4. If the cold, hot water pressure ratio of more than 8: 1 should be installed on the side of the pressure limit     valve to ensure that the Mixer valve can be properly adjusted.  5. In the selection and installation, please note that the nominal pressure, Mixer temperature range     and other requirements are consistent with the product parameters.    Use and commissioning precautions:  1. The debugging temperature should be the maximum flow of water to open.  2. The adjustment knob is the direction of rotation is slow, reverse rotation direction is heating, the initial     adjustment, please pay attention from the low temperature direction to adjust the direction of high temperature     to prevent burns.  3. The control button in the direction of low temperature is to close the hot water, high temperature direction is the     end of the cold water, if the hot water temperature is not high, you can close the cold water only hot water bath,     but after use should pay attention to high back to low temperature area, Use burns when used.  4.
