System Charging

WARNING: This page is about a different car, the 2011 Honda Insight and 2010 Honda Insight. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
  • Air conditioning refrigerant or lubricant vapor can irritate your eyes, nose, or throat.
  • Be careful when connecting service equipment.
  • Do not breathe refrigerant or vapor.
  1. Connect an R-134a refrigerant recovery/recycling/charging station (A) to the high-pressure service port (B) and the low-pressure service port (C), as shown, following the equipment manufacturer's instructions.

  2. Recover the refrigerant in the A/C system (see REFRIGERANT RECOVERY ).
  3. Evacuate the system (see SYSTEM EVACUATION ). If the system cannot reach a vacuum of-93.3 kPa (-700 mmHg, -27.55 inHg) in 15 minutes, or cannot hold a vacuum for at least 15 minutes, there is probably a large leak. Do the refrigerant leak check (see REFRIGERANT LEAK CHECK ), and repair any leaks before charging the system.
  4. Add the same amount of new refrigerant oil to the system that was removed during recovery. Use only SP-10 refrigerant oil.
  5. Charge the system with the specified amount of R-134a refrigerant. Do not overcharge the system; the compressor will be damaged.

    Select the appropriate units of measure for your refrigerant charging station.

    Refrigerant Capacity: 450 to 500 g 

    0.45 to 0.50 kg 

    0.99 to 1.10 lbs 

    15.8 to 17.6 oz 

  6. Check for refrigerant leaks (see REFRIGERANT LEAK CHECK ).
  7. Check for system performance (see A/C SYSTEM TEST ).
