Charging the System

Print


CAUTION
For personal protection, goggles and gloves should be worn and a clean cloth wrapped around fittings, valves, and connections when doing work that includes opening the refrigerant system. If R-134a comes in contact with any part of the body severe frostbite and personal injury can result. The exposed area should be flushed immediately with cold water and prompt medical help should be obtained.


WARNING
To avoid system damage use only R-134a dedicated tools when servicing the A/C system.

  1. A complete air conditioning service center for R-134a will be needed.
  2.  
  3. Remove A/C refrigerant system service caps.
  4.  
  5. Attach the high-side hose with the quick disconnect coupler to the high-side fitting of the vehicle's A/C system.
  6.  
  7. Attach the low-side hose with the quick disconnect coupler to the low-side fitting of the vehicle's A/C system.
  8.  
  9. Close the low-side valve on the control panel.
  10.  
  11. Open the high-side valve on the control panel.
  12.  
  13. Refer to the manufacturer's instructions for the charging station in use.
  14.  
  15. Enter the amount of refrigerant needed to charge the A/C system.
  16.  
  17. Install 1.10 lbs. of R-134a refrigerant.
  18.  
  19. Close the high-side valve on the unit's control panel. Both valves should be closed.
  20.  
  21. Start the vehicle and the A/C system.
  22.  
  23. Let the engine run until the readings on the high-side gauge and the low-side gauge stabilize.
  24.  
  25. Compare the readings to the system specifications.
  26.  
  27. Check the evaporator outlet temperature to ensure that the A/C system is operating within the system specifications.
  28.  
  29. Keep the A/C running.
  30.
