Air Conditioning (A/C) System Recovery, Evacuation and Charging: Evacuation

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

NOTE: Use an A/C refrigerant analyzer before recovering any of the vehicle's 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 in accordance with all federal, state and local regulations. For all equipment, follow the manufacturer's instructions.
- 198-RI2012yfp A/C Refrigerant Analyzer for use with R134a and R1234yf vehicles Use the General Equipment: Refrigerant Identification Equipment
Connect the tool to the low-side and high-side service gauge port valves following the manufacturer's instructions.
- 265-37887 Ritchie R134A A/C Refrigerant Hybrid Management System Use the General Equipment: Air Conditioning Service Unit
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.
Turn off the vacuum pump. Observe the low-pressure gauge for 10 minutes to make sure the system vacuum is held.
