How to recover Freon from air conditioning?

A、将空调调制到制冷状态下：首先使用扳手将室外机两个连接管阀门的盖子给打开，然后需要使用5个的六角扳手，将其放到细的（高压阀）阀口，然后再阀门迅速的关上，大概20秒过去之后再将粗的阀门（低压）关上，然后才是关闭空调电源，断掉电源。这样做完之后就将氟收到外机中去了。这样就能够进行拆机工作了。

A. Modify the air conditioner to refrigerate: First use the wrench to open the cover of the two connecting pipe valves of the outdoor machine, then use five hexagonal wrenches to place them in the thin (high pressure) valve mouth, then the valve closes quickly, then close the thick (low pressure) valve after about 20 seconds, and then It is to turn off the air conditioning power and cut off the power. After this is done, fluorine is sent to the outside machine. This will enable the machine to be disassembled.

B、安装的时候还有开阀门排空：具体如下：把内外机固定好之后，把空调连接好，主要是把内外机连接管都紧好，注意一定接好，以防制冷剂泄露。

B. Installation of the valve is also open empty: specific as follows: after the internal and external units are fixed, the air conditioning connection is good, mainly the internal and external units are tightly connected pipe, pay attention to a good connection, in order to prevent refrigerant leakage.

C．开关打到自动档空调就正常工作，用内六角打开高压阀门（细管阀门），再用六角顶住加氟口顶针（加氟口在低压上），使里面的气体跑出来，10秒钟左右就可以了，不要时间太长，以免雪种跑的太多。这样就可以使管路里面的空气放出来。

C. Switch to automatic gear on the normal work of air conditioning, with the hexagonal open high-pressure valves (pipe valves), and then with the hexagonal plug fluoride mouth (fluoride mouth on the low pressure), so that the gas inside run out, about 10 seconds, not too long, in order to avoid running too much snow. This way, the air in the pipeline can be released.

D．然后把高低压的阀门都打开，接假山制作 不锈钢铸件 铝箔真空袋 七孔梅花管 hdpe硅芯管 液压钢坝 PVC软管 飞行激光打标机 沥青保温泵上内外机的电源线就可以了。注意：连接管是铜的，不能盘成死弯，否则就会影响制冷剂的流动，造成不能制冷和制热。拆的时候要先收氟，否则就会造成氟的泄露。

D. then turn on the high and low pressure valves and connect the power lines inside and outside the machine. Note: the connecting pipe is copper, can not be coiled into a dead bend, otherwise it will affect the flow of refrigerant, resulting in no cooling and heating. Fluoride should be removed when it is removed, otherwise it will cause leakage of fluorine.
