WA RN ING:
Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and
throat. Remove HFC-134a (R-134a) refrigerant from the A/C system using certified service equipment
meeting requirements of SAE J2210 HFC-134a (R-134a) recycling equipment or SAE J2201 HFC-134a
(R-134a) recovery equipment. If an accidental system discharge occurs, ventilate the work area before
resuming service. Additional health and safety information may be obtained from the refrigerant and
lubricant manufacturers.
