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:
•
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.
