Note:
- This check is performed if a refrigerant leak is suspected or if work has been performed involving the removal of components or loosening of connections in fittings, tubes and hoses.
- To properly use the capabilities of the electronic detector, read the manufacturer's instructions for performing maintenance and testing work.
1. Check the tightening torque of the tube fastening nuts and, if necessary, tighten the fasteners to the rated torque. Check the tightness of the system using an electronic detector.
2. If the leak continues even after tightening the connections, evacuate the refrigerant from the system, disconnect the tubes and check their sealing surfaces for damage. Always replace the defective part, even if there is minor damage.
3. Check the amount of compressor oil in the system and add oil if necessary.
4. Fill the system with refrigerant and check it for leaks again. If no leaks are found, evacuate the system, then fill the system with refrigerant.
