Kind tips:
When you put the corkscrew into the bottle, do not use too much force. This will cause the rubber pad inside the corkscrew to deform and the gas cannot escape. Tighten with normal force.
If refrigerant is added, the pointer of the pressure gauge is around 8-13, that is, the air conditioner compressor is not working, and the air conditioner needs to be checked.
1. The air conditioner can enter the cooling state normally. Are there water droplets on the two external connectors after the air conditioner has been running for a period of time? Yes, normal; one with and without fluoride; no, without fluoride.
2. Open the inner cover and remove the filter. There are water droplets inside the copper tube, which is normal; hoarfrost, lack of fluoride; no, no fluoride.
