2. Refer to the manufacturer's instruction manual to learn more about filling machine. add the appropriate amount 100 PG lubricant
to the system.
3. When the fuel injection meet the requirement, close the valve.
Note
Remember to tighten the oil cap to prevent moisture or contaminants entering. This operation requires air-
conditioning systems to have a certain degree of vacuum. Do not open filling valve when the air-conditioning system
has a positive pressure, otherwise it will lead to oil flow back to the Oil Bottle. When filling or adding lubricant, the
oil level can not be lower than the oil-absorbing tube, otherwise air will enter the air-conditioning system.
Filling
Note
Empty before filling the air-conditioning system.
1. Close the Control Panel low pressure valve.
2. Close the Control Panel high pressure valve.
3. Refer to the manufacturer's instruction manual to learn more about filling machine.
4. Fill the air-conditioning refrigerant with necessary amount to ensure that the correct units measurement (i.e. kilograms or pounds).
5. Start Filling.
Refrigerant filling successfully completed
1. Close filling machine control panel high pressure and low pressure valves. two valves should be closed.
2. Start the vehicle and turn on the air-conditioning system.
3. Keep the engine running, until the high pressure and low pressure gage pressure readings are stable.
4. Compare the reading with the system specifications.
5. Check the evaporator outlet temperature to ensure that air-conditioning system operating system specifications.
6. Keep the air-conditioning running.
7. Close high pressure quick connector valve.
8. Disconnect the high pressure hose from the vehicle.
9. On the control panel, open high pressure and low pressure valves. The system will quickly inhale refrigerant through the low
pressure hose.
10. Disconnect the low pressure quick connector valves.
11. Disconnect the low pressure hose from the vehicle.
Refrigerant filling unsuccessful
Sometimes refrigerant entering the air-conditioning system does not meet the total filling volume. There are two reasons for this
situation:
1. Filling machine pressure and the air-conditioning refrigerant pressure is similar. It will lead to filling too slowly. Refer to the
manufacturer's instruction manual to learn more about filling machine.
2. There is not enough refrigerant in refrigerant tank for filling. In this regard, recover the refrigerant from the vehicle, and then
empty the air-conditioning system, add refrigerant to refrigerant tank, then finally re-fill. Refer to the manufacturer's instruction
manual to learn more about filling machine instructions.
