If gauge needle does not move from 0 cmHg (0 MPa) to –76 cmHg (–0.1 MPa), in step 3 above
take the following measure:
take the following measure:
- If the leak stops when the piping connections are tightened further, continue working from step 3.
- If the leak does not stop when the connections are retightened, repair location of leak.
- Do not release refrigerant during piping work for installation and reinstallation.
- Take care of the liquid refrigerant, it may cause frostbite.
- If the leak does not stop when the connections are retightened, repair location of leak.
