Refrigerant Leak Test

When a refrigerant leak is suspected or the connection part is disassembled or loosened, perform the leak test with an electronic leak detector.

1. Check the torque of the connection part, and if it is too loose, check the gas leak with leak detector after tightening it to the specified tightening torque.
2. If leakage continues even after re-tightening the connection part, drain the refrigerant and separate the connection part to check the contact surface for damage. If there is even a small damage, replace it with a new one.
3. Check the compressor oil and add oil if necessary.
4. Charging the system and check for gas leakage. If there is no problem, evacuate the system before charging.
