Correct wiring method of Yuba

First, prepare to install Yuba. After finishing the PVC ceiling in the bathroom at home, start to ventilate and install ventilation window. Generally, the ventilation pipes in ventilation window need to be about1.5m. Pay attention to the center of Yuba's installation position during installation, so the distance between ventilation holes should not exceed1.3m..

2. Secondly, determine the installation position of Yuba: The installation position of Yuba should be directly above the bathtub or shower room, so the ceiling of the bathroom should be made of materials with good strength. After installing the Yuba, make sure that the height difference between the Yuba bulb and the ground is between 2. 1 and 2.3m..

3. Finally, the installation process of Yuba: preparation for ceiling installation-removing the mask (unscrewing the light bulb and removing the lower cover from the ring of the mask)-wiring (connecting the Yuba and the switch panel with a flexible cord)-connecting the ventilation pipe-pushing the box into the air hole-fixing the Yuba lamp-installing the mask.

Yuba installing power supply line

1, the ground wire, the yellow and green one, is on the socket above the bathroom and connected to the shell of Yuba.

2. The neutral wire, which is blue or black in most cases, is connected to the socket on the left side of the bathroom and the screw buttons of five lamp holders.

3. The live wire, which is red in most cases, is located at the lower right of the socket and connected to the terminals of the three switches.

Three switches, one for lighting and the other connected to the central connecting post of the lighting head; Two lamp heating switches, and the other terminal of each switch is connected with the central terminal of two heating lamp holders. The Yuba terminal marked with N is connected to 0, and the other four terminals have two warm lights, one for ventilation and one for lighting. These four terminals are connected to the switch control button, and the other terminal is connected to the switch. It should be noted that the color of the wire should be made clear.

The position of Yuba's pressure line. There should be a wiring diagram on the instruction manual. If you don't understand, ask an electrician for safety. This is a bit complicated, because when I bought it, the control switch L 1 with several lines of color contrast was connected with the socket L. "That place is connected with a red line, and the socket is connected with a live wire. The other hole of the socket is connected to zero, and the other end of the switch is connected to the lamp.
