- The refrigerant is a chemical composition that must be handled with care to avoid harm to health.
- Work in a well-ventilated area and avoid breathing refrigerant vapors.
- When performing work related to the depressurization of the air conditioning system, always wear safety goggles and wrap fittings, valves and connections with a clean cloth.
- It is forbidden to carry out welding work on the car near the components and pipelines of the air conditioning system.
- Do not bend flexible pipe fittings (hoses) with a radius less than four diameters of the flexible insert.
- Inspect hoses regularly for cracks and fraying.
- Before disconnecting the piping of the air conditioning system, all refrigerant must be removed from it.
- Unscrew the threaded connections of the system elements slowly. Keep your face and hands away from the disconnect point to avoid injury if there is liquid refrigerant in the system.
- If pressure is detected in the system during the disconnection of the pipelines, remove the refrigerant from it, as described in subsection Removing refrigerant from the air conditioning system.
- Immediately after disconnecting any section of the system, immediately close the openings with caps or tape. This will prevent moisture and dirt from entering the system, which can cause failure of the compressor pumping part.
