Refrigerant Oil: Service Precautions

PRECAUTIONS TO BE OBSERVED WHILE SERVICING

NOTICE:
- Only use ND-OIL11 on the electric inverter compressor of the air conditioning system. Using other A/C oils may be dangerous, as they may conduct electricity.
- Electrical insulation performance may decrease significantly if even a small amount of the oil other than ND-OIL11 is used (or enters) in the refrigeration cycle, causing a DTC to be output.
- If other oil is accidentally used and a DTC is output, collect the compressor oil in the compressor and replace it with ND-OIL11 to increase the ND-OIL11 ratio amount.
- Replace the main components (evaporator, condenser, and compressor) if a large amount of oil other than ND-OIL11 enters the system. Failing to do so may cause electrical insulation performance to remain low, causing a DTC to be output.
