A/C Service Tips and Precautions

R-134a HANDLING / COMPATIBILITY PRECAUTIONS
- The air conditioning system uses HFC-134a (R-134a) refrigerant and polyalkyleneglycol (PAG) refrigerant oil (ND-OIL 8: PIN 38899-PR7-AO1), which are not compatible with CFC-12 (R-12) refrigerant and mineral oil.
- Do not use R-12 refrigerant or mineral oil in this system, and do not attempt to use R-12 servicing equipment; damage to the air conditioning system or your servicing equipment will result.
- Only use service equipment that is U.L.-listed and is certified to meet the requirements of SAE J2210 to remove R-134a from the air conditioner system.

CAUTION: Exposure to air conditioner refrigerant and lubricant vapor or mist can irritate eyes, nose and throat, Avoid breathing the air conditioner refrigerant and lubricant vapor or mist.

- If accidental system discharge occurs, ventilate work area before resuming service.
- R-134a service equipment or vehicle air conditioner systems should not be pressure tested or leak tested with compressed air.

WARNING: Some mixtures of air and R-134a have been shown to be combustible at elevated pressures and can result in fire or explosion causing injury or property damage. Never use compressed air to pressure test R-134a service equipment or vehicle air conditioning systems.

- Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers.
