1. DISCHARGE REFRIGERANT FROM REFRIGERATION SYSTEM
(a) Turn the A/C switch ON.
(b) Operate the cooler compressor at the engine rpm of approx. 1,000 for 5 to 6 minuites to circulate the
refrigerant and collect the compressor oil remaining in each component into the cooler compressor as
much as possible.
(c) Shut off the engine.
(d) Let the refrigerant gas out.

3. WARM UP ENGINE
4. INSPECT LEAKAGE OF REFRIGERANT
(a) Using a gas leak detector, check for leakage of the 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.
