4. INSPECT LEAKAGE OF REFRIGERANT

NOTICE:
1CD–FTV Hot gas heater:
Since the system uses a refrigerant filter (fixed valve), sound of the refrigerant circulation (hissing
sound) can be heard for approx. 30 seconds after turning the A/C off. This is merely a sound of bal-
ancing the low pressure with the high pressure, not a sound of abnormality.
