收氟步骤
Fluorine absorption step
1.开启空调，调整至制冷状态
1. Turn on the air conditioner and adjust it to the refrigeration state.
2.当空调开始制冷的时候，拿合适的六角扳手关闭空调外机的低压管阀门（就是比较粗的连接管的端部，打开旁边的螺帽即可）
2. When the air conditioner begins to refrigerate, close the low-pressure pipe valve of the external unit of the air conditioner with a suitable hexagonal wrench (that is, the end of the thicker connecting pipe, open the nut next to it).
3.仔细听，当压缩机的声音非常小的时候，再关闭高压管阀门（比较细的管子）
3. Listen carefully, when the compressor's voice is very small, then close the high-pressure pipe valve (thin pipe)
4.拔出空调的插头电源，收氟完成
4. Pull out the plug power supply of the air conditioner and collect fluorine.
关闭的时候要特别注意第三步，一定要等到压缩机的声音很小的时候才行。
Pay special attention to the third step when closing, and wait until the compressor's voice is very small.
