REFRIGERANT RECOVERY

WARNING: Avoid breathing air conditioning refrigerant or lubricant vapor. Exposure may irritate eyes, nose and throat. Also, due to environmental concerns, use service equipment certified to meet the requirements of SAE J2210 (R-134a recycling equipment) when draining R-134a from the air conditioning system. If accidental system discharge occurs, ventilate work area before resuming service.

1. Connect an R-134a recovery/recycling/recharging device to the vehicle and follow the device manufacturer's instructions
