In the article we will consider how to drain the refrigerant from the system, replace the sealing rings of tubes and parts and replace the filter element of the cabin air
Removal of refrigerant from the air conditioning system
If you need to perform work on depressurization of the system, then you need to remove the refrigerant from the system
It is necessary to release the refrigerant from the system either outdoors or in a well-ventilated room.
The refrigerant under atmospheric pressure changes from a liquid state to a gaseous state
It is necessary to release the refrigerant from the system slowly, in a thin stream.
When the refrigerant is drained, a certain amount of oil may be sprayed. Therefore, you need to put a rag near the bleed valve.
The work must be done in protective glasses
Unscrew the threaded cap of one of the two service caps
Press a thin screwdriver with a long sting on the tip of the valve spool and drain the refrigerant from the system
Replacement of O-rings
Sealing rings in the joints should be used only those intended for the air conditioning system, regardless of the fact that the dimensions are the same
When disassembling some connection, it is necessary to determine the design of the fitting in order to correctly select the type and size of the sealing rings
Before installation, make sure that neither the O-ring "A" nor the fitting "B" is damaged or deformed
When installing O-rings, they need to be lubricated with oil for the air conditioner compressor
Replacement of the filter element of the incoming air in the cabin

It is recommended to replace the filter element after 15 thousand km of car mileage. But in a dusty area, you need to replace the filter element as often as possible. The amount of air supplied through the heater and air conditioner depends on this.
