When removing and disposing of the refrigerant, always use caution and follow all safety precautions. Apply hand gloves and safety eyewear before proceeding with the following steps:

Locate the Low-Pressure Service Port on the boiler.

Connect the service hoses from the recovery machine to the service ports on the air conditioning system. Determine the location of the low-pressure service port. If you follow the hose and line assembly that runs from the rear of the compressor to the cylinder-like accumulator near the firewall, you will have an easier time locating it.

The low-pressure line is located on the rear of the compressor, and it is equipped with a low-pressure service port for connecting to the compressor.

In the high-pressure line (the smaller one) that runs between the firewall and the condenser (which is located in front of the radiator), the high-pressure service port may be found.

Launch the Recovery Machine

When you turn off the machine, you will remove the refrigerant vapor and non-condensable gases from the air conditioning system. Because part of the cooling ingredient will be liquid, the automotive ac recovery machine will lower the system’s pressure to convert them to vapor. It makes the removal of the refrigerant simpler.

When the system is not in use, the machine shuts down on its own. If the pressure in the system rises over a certain point, it will restart and begin drawing a vacuum. Otherwise, the refrigerant evacuation procedure will be complete if the system pressure remains under vacuum for five to ten minutes.

Disconnect the machine from the network.

The last step in removing refrigerant from a car’s air conditioning system is to unhook the unit from the service port. Before disconnecting the service hoses, you must shut the valves on the hoses. To remove R-12 type refrigerant from older units, you must install shut-off valves on the hose itself.
