INFOID:0000000004215282

SETTING OF SERVICE TOOLS AND EQUIPMENT

WARNING:

Avoid breathing the A/C refrigerant and electric compressor oil vapor or mist. Exposure may irritate

eyes, nose, and throat. Remove the HFC-134a (R-134a) from the A/C system using certified service

equipment meeting the requirements of SAE J2210 (R-134a recycling equipment) or SAE J2201 (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

electric compressor oil manufacturers.

CAUTION:

Use only Electric Compressor Oil ND-OIL 11 for the electric compressor of the air conditioning sys-

tem. Using other A/C oils may damage the A/C system as they may conduct electricity.
