Function: 1. Thermostatic bath faucet can automatically balance cold and hot water pressure to maintain stable water temperature in a short time, eliminating the need for manual adjustment. 2. This thermostatic shower mixing valve is made of durable brass. The faucet is resistant to na tarnishing and corrosion during everyday use. Ensuring quality and durability. 3. When the inlet temperature of cold practice remains unchanged, the pressure changes by 20%, respectively. The temperature change of wastewater is less than 1,5 . 4. When the cold and hot water pressure is constant, the hot water temperature ranges from 55 to 85. Cold water temperature changes at 8 -29 and wastewater temperature drops below 1,5 5. The shower valve is resistant na burns, so you and your family are safe. The valve will automatically turn off the shower head in the absence of cold water supply.

Do not turn on the water supply switch when the thermostatic valve is used when the solar tank has enough hot water. As long as the solar water tank needs water, it can be unscrewed. This only applies to thermostatic valves with water.2. When using a thermostatic valve in winter, the room temperature is lower than 0 . After use, close the final inlet valve connected to the cold water inlet. At the same time. The water residues in the valve body are discharged through the antifreeze wire to avoid frost damage to the valve body.3. After pressing the safety button, do not turn the thermostat knob quickly, otherwise the temperature will rise or fall sharply causing discomfort.4. Refer to the installation instructions or ask a professional to install.
