Charging Refrigerant System

NOTE: This step is to charge the system through the low pressure side with refrigerant in a vapor state. When the refrigerant container is placed right side up, refrigerant will enter the system as a vapor.




1. Attach an Air Conditioning Service Station as shown the figure.
2. Open the low pressure valve. Adjust the valve so that the low pressure gauge does not read over 412 kPa (4.2 kg/sq.cm, 60 psi)
3. Put the refrigerant in a pan of warm water on heat plate (maximum temperature 40 °C (104 °F)) to keep vapor pressure in the container slightly higher than vapor pressure in the system.
4. Run the engine at fast idle, and operate the air conditioner.

NOTE: Be sure to keep the container upright to prevent liquid refrigerant from being charged into the system through the suction side, resulting in possible damage to the compressor.




5. Charge the system to the specified amount. Then, close the low pressure valve.

Specified amount 575 - 625 g (1.27 - 1.38 lbs)
