Charging the Refrigerant System

WARNING: Always wear eye protection when charging the system.

NOTE: The A/C system may be charged with refrigerant by either Vapor or Liquid method:

CAUTION: Do not overcharge the system: the compressor will be damaged.





VAPOR CHARGING, through the LOW side:
1. Connect an Air Conditioning Service Station as shown, with all valves closed.
2. Open the low gauge valve [adjust it as necessary so pressure does not exceed 415 kPa (60 psi) while charging].
3. Start the engine and switch the air conditioner fan on high.

NOTE: Run the engine below 1,500 rpm.

4. Follow equipment manufacturer's instructions for vapor charging. Charge the system with 650 - 750 g (23 - 26 oz) of refrigerant until sight glass is free of bubbles (Some bubbles may appear; this is OK), indicating a full charge.
5. When fully charged, close the gauge valves, then the valve on the cylinder.
6. Disconnect Air Conditioning Service Station from vehicle.

LIQUID CHARGE through the HIGH pressure side:
Following the charging station manufacturer's instructions, charge the system with 650 - 750 g (23 - 26 oz) of refrigerant.

CAUTION: Do not run the engine during liquid charge; the compressor will be damaged.
