The steps for adding refrigerant (fluorine) to a home air conditioner are as follows
1, prepare a set of fluoridation tools.
2, prepare a bottle of refrigerant and fluoride tool connection.
3, the air conditioner will be turned on to run the cooling mode (winter can not be turned on to cooling, you can put the thermostat in hot water).
4, fluoride tube connected to the interface of the external unit (there are two copper tubes, add liquid need to connect the interface of the thick tube).
5, open the refrigerant cylinder valve and the pressure gauge three-way valve, began to add fluorine for a period of time (time to control themselves, different air conditioning refill time is different), close the cylinder valve, check the pressure gauge readings (readings will slowly fall back to the last static), the summer generally need to be added to the 0.4-0.5MPa, the winter in 0.3MPa or so.
