When the refrigerator with a fluorine content of less, you need to charge a refrigerant is, generally do not have traditional weighing method, and the use of pressure method and the method of observation, here on specific actions are described below.

Time after the refrigerator in the process of using combined meter valve for small flow rate of liquid refrigerant charge to 0.3MPa, stand 5 minutes. Power on the compressor running in 15 minutes, the debugging process of working pressure (known as low pressure). What is the first observation of low-voltage, if below the mouth from the craft 0.06MPa tonic gaseous refrigerant (can also be a small flow of liquid), extended over time (freezing room cooling), pressure will drop, supplemented with, in the process, to limit the power not exceeding 0.08MPa. Automatic shutdown, automatic and power-on, adjust the low voltage again. Will stop before the pressure regulation 0.06MPa (can also be a slight deviation 0.01). Repeated several times to complete.

Adjust the process to be patient, once twice is not precise adjustment. The high pressure valve directly from a table (higher than atmospheric pressure), do not worry about air mixed in.
