PRECAUTIONS HAC-211 < PRECAUTION > [AUTO A/C (WITHOUT HEAT PUMP)] C D E F G H J K L M A B HAC N O P 3. Check that the charge status indicator lamp does not blink and wait for 5 minutes or more. NOTE: If the battery is removed within 5 minutes after the power switch is turned OFF, plural DTCs may be detected. 4. Remove 12V battery within 1 hour after turning the power switch OFF → ON → OFF. NOTE: • The 12V battery automatic charge control may start automatically even when the power switch is in OFF state. • Once the power switch is turned ON → OFF, the 12V battery automatic charge control does not start for approximately 1 hour. CAUTION: • After all doors (including back door) are closed, if a door (including back door) is opened before battery terminals are disconnected, start over from Step 1. • After turning the power switch OFF, if “Remote A/C” is activated by user operation, stop the air conditioner and start over from Step 1. Precautions for Service Work of Cooler System INFOID:0000000010121919 GENERAL REFRIGERANT PRECAUTION WARNING: • Never breathe A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and throat. Remove HFC-134a (R-134a) from the A/C system, using certified service equipment meeting requirements of SAE J-2210 [HFC-134a (R-134a) recycling equipment], or J-2209 [HFC-134a (R-134a) recovery equipment]. Ventilate work area before resuming service if accidental system discharge occurs. Additional health and safety information may be obtained from refrigerant and lubricant manufacturers. • Never release refrigerant into the air. Use approved recovery/recycling recharging equipment to cap- ture the refrigerant each time an air conditioning system is discharged. • Wear always eye and hand protection (goggles and gloves) when working with any refrigerant or air conditioning system. • Never store or heat refrigerant containers above 52 °C (126°F). • Never heat a refrigerant container with an open flame; Place the bottom of the container in a warm pail of water if container warming is required. • Never intentionally drop, puncture, or incinerate refrigerant containers. • Keep refrigerant away from open flames: poisonous gas is produced if refrigerant burns. • Refrigerant displaces oxygen, therefore be certain to work in well ventilated areas to prevent suffo- cation. • Never pressure test or leakage test HFC-134a (R-134a) service equipment and/or vehicle air condi- tioning systems with compressed air during repair. Some mixtures of air and HFC-134a (R-134a) have been shown to be combustible at elevated pressures. These mixtures, if ignited, may cause injury or property damage. Additional health and safety information may be obtained from refriger- ant manufacturers. WORKING WITH HFC-134a (R-134a) CAUTION: • CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. Compressor mal- function is likely to occur if the refrigerants are mixed, refer to “CONTAMINATED REFRIGERANT” below. To determine the purity of HFC-134a (R-134a) in the vehicle and recovery tank, use Refriger- ant recovery/recycling recharging equipment and Refrigerant Identifier. • Use only specified lubricant for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) compo- nents. Compressor malfunction is likely to occur if lubricant other than that specified is used. • If rotary compressor oil (DH-PR), swash plate compressor oil (DH-PS), or CFC-12 compressor oil (mineral oil) is used, the insulation resistance may be reduced. Never use these oils. • The specified HFC-134a (R-134a) lubricant rapidly absorbs moisture from the atmosphere. The fol- lowing handling precautions must be observed: - Cap (seal) immediately the component to minimize the entry of moisture from the atmosphere when removing refrigerant components from a vehicle. - Never remove the caps (unseal) until just before connecting the components when installing refrig- erant components to a vehicle. Connect all refrigerant loop components as quickly as possible to minimize the entry of moisture into system. |
