307Check 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. )

3104. A/C Compressor Removal / Installation1. Disconnect the negative (--) terminal cable from the battery.
2. Drain the refrigerant from the system.
3. Detach the radiator.
4. Loose the drive belt and then remove the drive belt.Notice:•If anything moisture or any foreign matter enters into the Refrigeration system for circulation,
the cooling performance of the Refrigeration system will obviously deteriorate with abnormal
noise. Plug the port immediately after removing any cooling circulation component to prevent
anything moistur or any foreign matter from entering the circulation.5. Remove the compressor inlet and outlet pipe.
6. Removemagnetic clutch connector.
7. Remove the compressor.
8. The installation is in the reverse order of the removal.
9. Adjust the drive belt.
10. Check the Refrigeration system performance.5. The Condenser Removal / Installation1. Disconnect the negative (--) terminal cable from the battery.
2. Drain the refrigerant from the system.Notice:•If anything moisture or any foreign matter enters into the Refrigeration system for circulation,
the cooling performance of the Refrigeration system will obviously deteriorate with abnormal
noise. Plug the port immediately after removing any cooling circulation component to prevent
anything moistur or any foreign matter from entering the circulation.3. Remove the condenser inlet and outlet pipeline to prevent the compressor oil from splashing.
4. Remove condenser fan connector.
5. Remove the engine hood lock.
6. Remove the engine hood lock support brace.
7. Remove the condenser.
8. The installation is in the reverse order of the removal.
9. Check the Refrigeration system performance.The Condenser Installation Description:1. When installing the new condenser, it is recommended to fill certain SW-100 compressor oil into the
refrigerant circuit.Refill: (approximate)
20ml{20 cc }

311Check the condenser1. Check for crack, damage or oil leakage.
•Replace the condenser if any of the above-mentioned faults occurs.
2. Check if the fin area is blocked by dust.
•Clean it if it is blocked.
3. Check if the fin area bends.
•If the fin area bends, level it with a flat head screwdriver.6. Refrigeration Pipeline Removal / Installation1. Remove battery.
2. Drain the refrigerant from the system.
3. Remove air filter.
4. Remove the clamp.
5. Remove the compressor inlet hose.
6. Remove the compressor outlet hose.
7. Remove liquid pipe I.
8. Remove pressure switch connector.
9. Remove the pipe clamp.
10. Remove liquid pipe II.
11. The installation is in the reverse order of the removal.Notice:•If anything moisture or any foreign matter enters into the Refrigeration system for circulation,
the cooling performance of the Refrigeration system will obviously deteriorate with abnormal
noise. Plug the port immediately after removing any cooling circulation component to prevent
anything moistur or any foreign matter from entering the circulation.
Introduction Of The Refrigeration Pipeline Removal:
Nuts union type:Loose the nuts with 2 wrenches and then remove the refrigeration pipe (or the hose).Slider joint type:Clip the slider block recess end with pliers or the similar tool and remove the attaching bolt or screw cap.

312Introduction Of The Refrigeration Pipeline Installation:
1. It is recommended to fill some SW-100 compressor oil into the refrigerating circulation when installing a
new refrigeration pipe or cooling hose.
Refill: (approximate)
5ml{5 cc}: Refrigeration pipe
10ml{10 cc}: Condenser hose
2. Fill compressor oil to O-ring and other connecting points.
3. Tighten the connecting points.
Nuts union or slider joint type:
1. Tighten the nuts or the bolts of the connectiong
points by hand.
2. Tighten the connecting points with specified
torque wrench. It is connected with nuts. Tighten
the nuts with a wrench or a torque wrench.
3. Clip the slider block recess with pliers or other
similar tool and clamp the pipe used to connect
slider block. Tighten the bolt or the nuts at the
connecting points with a torque wrench.
7. A/C control panel removal / installation:
1. Disconnect the negative (--) terminal cable from the battery.
2. Remove the auxiliary console.
3. Disconnect the hot and cold air cable and airflow allocating cable.
