Separate equipment and appliances designed to work with R-12 and R-134a refrigerants and never mix them up.
Warning
When working with R-134a refrigerant:
- Always use eye protection.
- Avoid contact with eyes or skin. If this occurs:
- Do not rub your eyes or skin.
- Rinse eyes or skin with plenty of cold water.
- Seek immediate medical attention, do not attempt to help yourself.
- Store refrigerant containers at temperatures below 40°C.
- Keep away from sources of fire. Although the refrigerant itself is not flammable, it emits toxic gases when in contact with fire.
- Work in a well-ventilated area. The refrigerant evaporates very quickly and can displace all the air in a small, enclosed space.
1. Always disconnect the negative battery cable when working on the A/C system.
2. Keep the work area clean and dry. Do not allow moisture or dirt to enter the system. When working on the system, put on protective caps or connect connections without delay. Remove the protection only immediately before connecting the pipelines.
3. Before connecting each tube or hose, apply a small amount of refrigeration oil to the O-rings.
4. When tightening or loosening the connection, use a second wrench to support the stationary part of the connection.
5. When the system is degassed, do not allow the refrigerant to escape too quickly, as this may result in oil being carried out of the system.
6. Add refrigeration oil after replacing the following parts:
Note:
- Do not return the oil to the container that was filled and do not mix it with other oil.
- Immediately after filling the oil, install the lid with the gasket on the container to prevent moisture absorption.
- Do not spill refrigeration oil on the car body, it may damage the paint. If oil gets on the body, wipe it off immediately.
- Condenser - 20 ml./25 ml.
- Evaporator - 45 ml./60 ml.
- Tubes and hoses - 10 ml./10 ml.
- Reservoir/Desiccant - 10ml/10ml.
- Elimination of leaks - 25 ml./25 ml.
- Compressor - To replace the compressor: subtract the amount of oil drained from the removed compressor from quantity A. And drain the calculated volume of oil from the new compressor: A - Volume from the removed compressor = Volume to pour in from the new compressor. A: Sanden&Hadsys=130 ml. Nippondenso-140 ml
Note: If no oil has drained from the removed compressor, do not drain more than 50 ml from the new compressor.
