Use only lubricant specifically designed for HFC-I34a refrigerant systems (R-134a) (Nissan A/C System Oil Type R). Using a different lubricant may cause compressor failure.
This lubricant quickly absorbs moisture from the air. For this reason, the following precautions must be observed:
- When removing parts of the air conditioning system or disconnecting pipelines, immediately close the openings to prevent atmospheric moisture from entering the system.
- When installing parts of the air conditioning system, remove the plugs immediately before connecting to the system. Connect as soon as possible.
- Use only grease stored in a sealed container. Close container immediately after use.
Avoid breathing refrigerant and fumes from refrigerant lubricants. This can irritate the mucous membranes and wasp and throat. In case of sudden depressurization of the system, continue working only after the room has been completely ventilated.
Wear protective goggles and gloves when working on the air conditioning system.
Do not allow refrigerant containers to reach temperatures above 52°C. Keep the refrigerant away from open flames as it releases poisonous gas when ignited.
Do not use compressed air to purge the air conditioning system.
