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.
