Air Conditioning (A/C) System Recovery, Evacuation and Charging — 2016 workshop reference 3603

2. NOTE: Never attempt to recover from only the low side service gauge port valve (solenoid valves in the system will not allow for full recovery).

Evacuate the system until the low-pressure gauge reads at least 99.4 kPa (29.5 in-Hg) of vacuum and as close to 101.1 kPa (30 in-Hg) as possible. Continue to operate the Vacuum Pump for a minimum of 45 minutes.

3. Turn off the vacuum pump. Observe the low-pressure gauge for 10 minutes to make sure that the system vacuum is held.

Charging

NOTICE: An A/C refrigerant analyzer must be used before the recovery of any vehicle's A/C refrigerant. Failure to do so puts the shop's bulk refrigerant at risk of contamination. If the vehicle's A/C refrigerant is contaminated, refer the customer to the service facility that carried out the last A/C service. If the customer wishes to pay the additional cost, use the A/C recovery equipment that is designated for recovering contaminated A/C refrigerant. Dispose of all contaminated A/C refrigerant as hazardous waste. For all equipment, follow the manufacturer's instructions.

1. Lubricate the refrigerant system with the correct amount of clean PAG (polyalkylene glycol) oil. Refer to: Refrigerant Oil Adding (412-00 Climate Control System - General Information, General Procedures).

2. Connect the tool to the low-side and high-side service gauge port valves following the manufacturer's instructions. Use the General Equipment: Air Conditioning Service Unit

3. Set the refrigerant charge amount, and charge the refrigerant system following the manufacturer's instructions.
