How to Use 1.Put the water sensor on the place where water leakage may happen. 2.Turn off the valve and connect it to water pipe and make sure the valve interface no leaks. 3.Connecting the valve with the central unit. 4.Connecting central unit with the AC power (Power LED indicator will light up. Sound one beep and Sensor LED will light from Sensor 1 to Sensor 8). 5.Press the OPEN button to open the valve. 6.Once leakage happens, sensor will detect the water, the central unit will immediately alarm warning and corresponding LED will light up, then the valves will automatically shut off. 7.User can repair the place where water leak happens according to the audible alarm and press the RESET button to turn off the alarm. 8.After all leakage got repaired, press the OPEN button to open the valve (you can also press the CLOSE button to test if the valve is working properly). 9.Press Reset button and resume to Standby state. 10.Keep the water sensor flat where water leakage may happen after sopping up the water,the device can be recycled.
