Recycle Refrigerant


WARNING:
- Always use HFC-134a for refregerant gas. If CFC-12 is accidentally charged, compressor is damaged due to insufficient lubrication.
- Always observe and follow precautions described on refrigerant container. Incorrect handling may result in an explosion of refrigerant container, frostbite, or the loss of eyesight.
- Never breathe refregerant gas and libricant vapor or mist. Exposure my irritate eyes, nose, or throat.
- Never allow HFC-134a to be exposed to an open flame or others because it generates poisonous gas when in contact with high temperature objects. Keep workshop well ventilated.
- To prevent fluorescent indicator from entering, prepare and use exclusive hose for EV (electric vehicle) and HEV (hybrid vehicle) when connecting recovery/recycling/recharging equipment.
1.Perform oil return operation. Refer to "Perform Lubricant Return Operation" Perform Lubricant Return Operation. (If refrigerant or lubricant leakage is detected in a large amount, omit this step, and then GO TO 2.)

CAUTION:
Never perform lubricant return operation if a large amount of refrigerant or lubricant leakage is detected.
2.Check gauge pressure readings of recovery/recycling/recharging equipment (for HFC-134a). When remaining pressure exists, recycle refrigerant from high-pressure hose and low-pressure hose.
NOTE:
Follow manufacturer instructions for the handling or maintenance of the equipment. Never fill the equipment with non-specified refrigerant.
3.Remove A/C service valve cap from the vehicle.
4.Connect recovery/recycling/recharging equipment (for HFC-134a) to the A/C service valve.
5.Operate recovery/recycling/recharging equipment (for HFC-134a), and recycle refrigerant from the vehicle.
6.Evacuate air for 10 minutes or more to remove any remaining refrigerant integrated to compressor lubricant, etc.
7.Refrigerant recycle operation is complete.
