How to Release Excess Refrigerant?

[JoshuaLynn]

The proper method to release excess refrigerant is by using an automotive refrigerant recovery and charging machine. The specific steps are as follows: 1. Before discharging and recovering the refrigerant, prepare the automotive refrigerant recovery and charging machine along with a refrigerant tank that has sufficient remaining capacity; 2. Connect the hoses of the automotive refrigerant recovery and charging machine to the high and low pressure pipes of the car's air conditioning system—red hose to the high pressure pipe and blue hose to the low pressure pipe; 3. After ensuring all connections are correct and the machine has completed its self-test upon startup, set the desired amount of refrigerant to be recovered and initiate the recovery process. The machine will then automatically begin discharging and recovering the excess refrigerant. An informal method of releasing refrigerant involves directly discharging it into the atmosphere through the high pressure pipe valve of the air conditioning system.
