Recovery

NOTICE: Use an A/C refrigerant analyzer before recovering any of the 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 in accordance with all federal, state and local regulations. For all equipment, follow the manufacturer's instructions.

  1. NOTE: Use only Ford Approved R134A refrigerant management equipment.

    Verify the refrigerant purity prior to recovery. Refer to Refrigerant Identification Testing procedure in Group 412.

      Use the General Equipment: Refrigerant Identification Equipment
  1. 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
  1. 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). Open solenoid valves.

    Recover the refrigerant from the system following the manufacturer's instructions. Note the amount of oil removed during the refrigerant recovery (if any). Add that same amount back into the system once repairs are complete. Refer to Refrigerant Oil Adding procedure in Group 412.
  1. Allow the system to set for about 2 minutes and observe the system vacuum reading. If the vacuum is not lost, disconnect the recovery equipment.
  1. If the system loses vacuum, repeat Steps 3 through 5 until the vacuum level remains stable for 2 minutes.
  1. Carry out the required repairs.

Evacuation

  1. NOTICE: 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.

    • 265‐37887 Ritchie R134A A/C Refrigerant Hybrid Management System
      Use the General Equipment: Air Conditioning Service Unit
  1. 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.
  1. Turn off the vacuum pump. Observe the low-pressure gauge for 10 minutes to make sure the system vacuum is held.

Charging

  1. NOTICE: 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.

      Use the General Equipment: Refrigerant Identification Equipment
  1. Lubricate the refrigerant system with the correct amount of clean POE oil. Refer to Refrigerant Oil Adding procedure in Group 412.
  1. 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

    Emergency Locking

    Each door has a backup power system which allows the door to function if your vehicle has no power. The system has a limited number of operations before the power is depleted and turns off. When the system turns off, the door remains open and unlatched and does not close.

    If your vehicle has no power and the backup power system is turned off, you can close and secure your vehicle by manually resetting each door latch using a key in the position shown.
