Recycle Refrigerant

WARNING: This page is about a different car, the 2018 Nissan Titan XD and 2018 Nissan Titan. However, it is still accessible from the selected car via links, so may be relevant.

WARNING:

Always use HFC-134a for A/C refrigerant. If CFC-12 is accidentally charged, compressor damage due to insufficient lubrication will result.
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.
Do not breathe A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose, or throat.
Do not allow HFC-134a to be exposed to an open flame or other ignition sources because it generates poisonous gas when in contact with high temperature objects. Keep workshop well ventilated.

Perform oil return operation. Refer to Perform Oil Return Operation . (If refrigerant or oil leak is detected in a large amount, omit this step, and go to step 2.)
CAUTION: Do not perform oil return operation if a large amount of refrigerant or oil leak is detected.
Check gauge pressure readings of recovery/recycling/recharging equipment. 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. Do not fill the equipment with non-specified refrigerant.
Remove A/C service valve cap from the vehicle.
Connect recovery/recycling/recharging equipment to A/C service valve.
Operate recovery/recycling/recharging equipment, and recycle refrigerant from the vehicle.
Evacuate air for 10 minutes or more to remove any remaining refrigerant integrated into compressor oil, etc.
Refrigerant recycle operation is complete.
