How to use

• Put the water sensor on the place where water leakage may happen

• Turn off the valve, and connect it to water pipe, to be sure the valve interface can not have leaks, then the valve connected to the central unit 

• Connect central unit to the AC power,(Power LED indicator will light up. Sound one beep and Sensor LED will light from Sensor 1 to Sensor 8press the OPEN button to open the valve.

• Once leakage happens, when the water touch the water sensor, the central unit will immediately sound warning tone and corresponding LED light up (until there is no detection of leakage,If more than one Sensor detected water leakage, all corresponding LED will also light up ), then the valve will automatically shut off

• User can repair the place where water leak happens according to the audible alarm, and press the RESET button to turn off the alarm

• After maintenance and all the leakage were repaired, press the OPEN button to open the valve (you can also press the CLOSE button to test if the valve is working properly). press Reset button and resume to Standby state

• Keep the water sensor flat where water leakage may happen after sopping up the water, the device can be recycled




1. Even without electric ball valve, the central unit will operate, detect water leakage and sound warning tone but the sound level s a little smaller than with AC power 2.Central unit is not waterproof, Therefore please do not place the unit at where water may flow.

3. Do not place Sensor terminals on the metallic objects that may cause false warning sound.
