  → Observe the safety regulations for working on air-conditioned vehicles and handling refrigerant.
  
  → Observe the safety regulations for extraction and filling systems.
  
  → Observe the instructions for repairing air-conditioning systems and storing spare parts.
NOTE:
Opened refrigerant system for repairs.
- Moisture penetrated into the refrigerant system.
- Risk of contaminating the refrigerant circuit.
- Risk of saturation and irreparable damage to desiccator.
- Irreparable damage to the desiccator can damage the compressor and evaporator.
  → The desiccator must be replaced if the air humidity is high and if the refrigerant circuit is left open for a long time.
Information
- Open connections and lines must be closed off using suitable stoppers or caps.
Disconnect air-conditioning lines -1- and -2- at the condenser.
