4.On the other hand, the larger one of the two silver layers is the positive one and the smaller one is the negative one.When welding the power cord, it must be soldered on the side with two silver layers , The other side of the vibration ,can be affixed to the wash basin under (this is purchased ceramic transducer components described); Circuit board and the first vibration (ceramic chip transducer) wiring instructions:1.Circuit board shall not be empty power;2.No cleaning fluid cleaning;3.Shock the first two lugs, the middle of the two pieces of ceramic sheet for the positive electrode, by the upper and lower metal column for the negative, may not be reversed ceramic sheet is not to high temperature silver, soldering the power cord when the temperature does not exceed 280 degrees,the most Good use of constant temperature iron, the iron temperature can be set to 250 degrees.5.Shock head on the larger side (with a screw hole) for the vibration can be stuck in the wash basin at of the wash basin to a reliable grounding. Board radiating .homogeneous sounding board. Ultrasonic cleaning transducer Cleaner 6.Earthquake head or transducer ceramic tile application head adhesive firmly affixed to the bottom of the wash basin;7.Two shock head parallel connection to the circuit board terminal, a circuit board up to two with the first shock, but also with a shock supporting the use of.8.Circuit board wiring diagram is as follows:Positive and negative output pole respectively positive and negative link, can not pick the wrong question in time advice, to safety, Weight: 1.66889932334 pounds, Manufacturer: Jaywool
