The air conditioner outdoor unit tube joint frost even frozen, then the cooling effect is not very good, let people to put the tube for tube, it is flat, then wash the indoor and outdoor unit for good, but after the tube joint is still the same, even frost freezing, refrigeration effect is very poor, cold still cold, but the results are poor, not very cool. Today, I called the master again. He checked and said there was no air leak, then all the gas was drained and the snow was renewed. Later, that tube interface still frosted, I do not want to call the master, and too much water, so many times can not do.I have always stressed and master is not completely open tube valve is not so cold medium to plugging in there, he has not said, I just want to do you need to twist the valve, how to operate, I just want to look at the valve is not open to the maximum torque.
If it has been opened to the maximum opening, the cooling effect is still not good, and here frost and ice, should consider replacing filters, after washing the pipeline, re vacuum and refrigerant.
As long as the counterclockwise rotation, with the starting force of about 10% of the screw can not move, it means that it has been opened to the maximum degree.
Find the right size of the six angle wrench, facing the cut-off valve, counterclockwise turn on the valve, clockwise turn off the valve.
