Note: This operation is performed to charge the system with refrigerant in a vapor state through the low-pressure circuit. When the container with refrigerant is in a vertical position, the latter is supplied to the system in the form of vapor.
1. Set the refrigerant container valve to the position specified above in the section "Actions with the system charging valve".
2. Open the low pressure circuit valve and adjust its position so that the pressure on the low pressure gauge does not exceed 412 kPa.
3. To ensure that the vapor pressure in the container with the refrigerant slightly exceeds the pressure in the system, place the container in a vessel with warm water (with a temperature of about 40°C).
4. Start the engine at fast idle and turn on the air conditioner.
Note: Keep the refrigerant container in an upright position to prevent liquefied refrigerant from entering the system through the suction line, which may cause damage to the compressor.
5. Fill the system with the required amount of refrigerant, then close the low-pressure circuit valve. Amount of refrigerant to be filled: 500±25g.
6. At a reduced rate of refrigerant filling, immerse the container with refrigerant in warm water (with a temperature of about 40°C).
