No air bubble in observation win-
No temperature difference between
Obvious temperature difference be-
tween the inlet and outlet of compressor.
Observation window is in clear status
once the air-conditioner is turned off
There is refrigerant foam on observa-
tion window after the air-conditioner
is turned off, then the observation
window becomes clear.

Check to see whether there is leakage with the
gas leakage detector
Refers 3 and 4.
Vacuumize the system and inflate the
refrigerant, then check to see whether there is
leakage with the gas leakage detector.
Refer 5 and 6
Exhaust the redundant refrigerant until the speci-
