How much refrigerant should be added to a Geely Englon?

[McNova]

Geely Englon requires 300 grams of refrigerant. Preparation: Before adding refrigerant, prepare tools and materials such as an automotive refrigerant recovery and charging machine, refrigerant (most car air conditioners currently use R-134a refrigerant, and different refrigerants must not be mixed). Connecting the pipes: Connect the pipes of the automotive refrigerant recovery and charging machine to the high and low-pressure pipes of the car's air conditioning system (red connects to the high-pressure pipe, blue connects to the low-pressure pipe). Vacuuming: After ensuring the pipes are correctly connected and the refrigerant recovery and charging machine completes its self-check upon startup, you can begin the vacuuming process for the car's air conditioning system. Adding refrigerant: Only after the vacuuming is completed can you start adding refrigerant. Based on the maximum refrigerant capacity marked on the vehicle's air conditioning system, set the charging capacity, time, and type on the refrigerant recovery and charging machine. After confirmation, the machine will automatically begin adding the refrigerant.
