1、The inlet valve has a filter screen to avoid impurities blocking the valve body, more practical. 2、Suitable for sauna room, bath place, spa tank, hot spring pool, spa pool, steam room and other controlled water spraying scene. 3、Made of high quality plastic and stainless steel material, durable and wear resistant. 4、When using a sauna heater, you need to sprinkle water to have steam. With this automatic spray device, it will automatically spray water without pouring water and save time. 5、Easy to install and operate, excellent workmanship and stable performance. 1 x Inductive Head1 x Spray System1 x Spray-Head1 x Inlet Valve1 x Stainless Steel Tube Condition: 100% Brand NewItem Type: Spa Control SwitchMaterial: Plastic + Stainless SteelColor: As shown in the pictureSize: Approx. 27x 14.5x3cm / 10.6x 5.7x 1.2in Weight: Approx.951g/ 33.5ozApplication: Suitable for sauna room, bath place, spa tank, hot spring pool, spa pool, steam roomInduction Head Voltage: DC12VBattery Valve Voltage: AC12VSpray Device: Power supply voltage AC220V, output: 12vInlet Valve: AC-12VInlet Valve Diameter: Male thread 21mm/ 0.8inPlease note when installing: 1. When installing the solenoid valve, please note that the arrow direction on the valve body is the same as the water flow direction. It must be connected to the water pipe with a hose to minimize the pressure. 2. A valve must be added in front of the solenoid valve for water volume adjustment and maintenance. 3. The connecting pipe between the solenoid valve and the sauna heater should retain a trap to prevent the solenoid valve from being burned out by the sauna heater. 4. For multiple panel switches, please connect them in parallel between V+ and SW (between 6# and 5#), generally no more than 5 at most. 5. For the water spray device equipped with sensors, when installing an induction head, the wiring should be between V+ and K1 (between 6# and 4#); if two induction heads are installed, the two induction heads should be the same when wiring Color lines are connected in parallel. If there are more sensor heads, it can be connected between V+ and K2 (between 6# and 3#). 6. Whether it is a sensor head or a switch, all the red wires are connected to V+ (6#). 7. The sensor should be installed in a location with relatively low temperature to avoid the influence of high temperature on internal components and cause the sensor to fail. 8. Time adjustment: the longest water spray time is 3 seconds, and the time can be reduced by flipping the switch upward, and it will be reduced by 0.5 seconds for each switch (generally do not adjust at will). 9. Troubleshooting: The solenoid valve keeps water out: Please check whether the solenoid valve inlet and outlet pipes are installed in the direction of the arrow. If the inspection is correct, please check whether there is any foreign matter inside the solenoid valve. The solenoid valve does not flow out: After powering on, look at the right indicator on the controller. If it is always on, it may be that the panel switch is not installed or not working, or the wiring is wrong, just connect according to the diagram.
