Attention.
- Use only those lubricants that are recommended for air-conditioning systems-134a (R-134a) and parts of air-conditioning systems-134a (R-134a).
- Use of lubricants other than those recommended may cause compressor failure.
- The lubricants recommended for HFC-134a (R-l34a) quickly absorb moisture from the atmosphere. The following precautions should be observed when servicing the air conditioner:
- When removing system parts from the vehicle, immediately seal them with plugs (seals) to reduce the penetration of atmospheric moisture into the parts.
- When installing air conditioner parts on a vehicle, do not remove the plugs (seals), until other parts are connected. Connect all parts of the air conditioning circuit as quickly as possible to reduce moisture penetration into the system.
- Use only the recommended lubricant in a sealed container. Close the container immediately after use. Loosely sealed lubricant will become saturated with moisture and cannot be used further.
- Avoid contact with grease (nissan Air Conditioning System S Oils) on the foam parts. This may cause damage.
General precautions when working with refrigerant
Attention.
- Avoid open ventilation of the air conditioning circuit and do not expose the oil to steam or moisture. Emissions may cause irritation to the eyes, nose and throat. Use only approved refrigerant recycling/exchange equipment to bleed HFC-134a (R-134a) refrigerant from the system. If refrigerant leaks, ventilate the area thoroughly before continuing. Additional health and safety information can be obtained from the refrigerant and lubricant manufacturers.
- Do not release refrigerant into the atmosphere. Use approved refrigerant recovery/replacement equipment to capture refrigerant as it is released from the system.
- When working with any refrigerant or any air conditioning system, always wear safety glasses and gloves to protect your eyes and hands.
- Do not heat the container with refrigerant (including during storage) to temperatures above 52°C.
- Do not expose the refrigerant container to open flame; if the container needs to be heated, place the bottom of the container in a bucket of hot water.
- Do not intentionally throw, puncture or burn the refrigerant container.
- Keep refrigerant away from open flame. Combustion of refrigerant produces toxic gas.
- The refrigerant displaces oxygen, so to prevent suffocating effects, it is necessary to work with it in a well-ventilated area.
- Do not perform a leak test on the service equipment and/or the vehicle's air conditioning system or a leak test for HFC-134a (R-134a) refrigerant using compressed air during repair work. In certain proportions, a mixture of air and HFC-134a (R-134a) refrigerant becomes flammable under high pressure. If ignited, this mixture may cause injury or serious damage. Additional health and safety information may be obtained from the refrigerant manufacturer.
