Geely CK Series 2007 Workshop Manual page 314

Check For Leakage:
1. Using leak detector, check refrigerant steel jar for leakage.
•
Go to Step 3 if there is no leakage.
•
Tighten the union joint if there is leakage at the loosened union joint and go to next step.
2. Re-check the leaked points.
•
Go to next step if there is no leakage after tightening the union joint.
•
If there is still leakage at the same union joint, drain refrigerant and vacuum the union joint.
3. Disconnect the high and low pressure pipe at the refill valve.
4. Install the filling valve cap.
Check Refrigerant Pressure:
1. Install the manifold gauge.
2. Warm up the engine and run it with constant 1800rpm.
3. Set the rpm of the cooling fan to the HIGHEST.
4. Turn on the A/C switch.
5. Set to internal circulation mode.
6. Set the temperature control mode to the COLDEST.
7. Set to be ventilation mode.
8. Close all door and windows.
9. Measure the environment temperature and the reading of the high pressure side and low pressure side
from the manifold gauge.
•
Shoot the Refrigeration system trouble as required if it is not as specified in the technical specification.
The Performance Inspection of the Refrigeration System:
1. Check refrigerant pressure.
•
Go to next step if the pressure value is correct.
•
Shoot the Refrigeration system trouble promptly if the pressure value is not as specified in the
technical specification.
2. Insert a thermometer into the middle vent port at the driver's side.
3. Warm up the engine and run it at the constant 1800rpm.
4. Set the rpm of the cooling fan to the HIGHEST.
5. Switch on A/C.
6. Set to internal circulation mode.
7. Set the temperature control mode to the COLDEST.
8. Set to Ventilation Mode.
9. Close all doors and windows.
10. Wait until A/C output temperature is constant. (When the environment temperature is 38°C, the temperature
at the middle ventilation port at the drivers side is 10°C~16°C. )
