Household air conditioning open is how liquid?
A. Refrigeration condition: Connect the two outdoor pipe cap, valve with a wrench open. With five hexagonal wrench, in fine (high pressure valve) valve mouth, close the valve quickly, in about 20 seconds later turn off the thick valve (low pressure), and then shut down, without electricity. Such fluorine is received outside the machine. It can tear open machine.
2. You have to open the valve installed on empty: Specific as follows: Fixed the inside and outside the machine, connect the air conditioning is good, mainly is to put the inside and outside the machine connecting pipe are tight, attention must be connected, in case of refrigerant leakage. With a hex switch to the automatic air conditioning work normally open thin tube (valve), high pressure valve in the hexagonal to resist to add fluoride mouth thimble (add fluoride mouth on the low pressure), make the ran out of gas, it is ok to 10 seconds, don't be too long time, so as to avoid the snow kind of run too much. So you can make the line of the air inside . Then put the high and low pressure valves are open, the inside and outside the machine electricity the power cord is ok. Note: the connecting pipe is copper, and cannot be bent into death, otherwise it will affect the flow of refrigerant, cause not cooling and heating. When need a fluoride, otherwise it will cause leakage of fluorine..Boot to lowest temperature, shut high-pressure pipe
You see the two outdoor copper tube, a thick, one thin, find a Allen wrench, open air conditioning refrigeration, the first close thin tube, the tube shut about three minutes in the coarse, then OK
