China ventilation fan motor manufacturers, how to install a household exhaust fan motor—installation of a household exhaust fan motor Turn on the household exhaust fan motor (make a mark and make a note), and you will see that the blue wire is composed of one auxiliary winding lead and one If the main winding leads are combined and led out, separate the secondary winding leads from the blue wire and lead out a single (new wire). At this time, the motor has four lead wires, the yellow wire (new wire), the red wire, and the blue wire. Just turn the red wire out. The blue line is replaced, the yellow line is connected in series with the same capacitor, the blue line merges with another capacitor line to one of the power lines, and the red line merges (new line) to the other power line, then the exhaust fan motor is installed.

Room ventilators—window ventilators Window ventilators are installed on the building's outer protective structure (doors and windows, curtain walls) or between the walls and doors and windows.
