So you can make the air inside the pipe to put out. 4. Then the high and low pressure valves are open, both inside and outside the machine's power cord is connected to it. Note: The connecting pipe is copper, not the disk into a dead corner, otherwise it will affect the flow of refrigerant can cause cooling and heating. Demolition when the first harvest of fluorine, otherwise it will cause leakage of fluorine.
