MAINTENANCE OF OIL LEVEL
The compressor oil is circulating in the system together with the refrigerant. It is necessary to fill compressor with oil when replacing A/C system parts or when a large amount of refrigerant leakage is detected. It is important to always maintain oil level within the specified level, otherwise the following conditions may occur:
Oil Type : A/C System Oil Type S
Inspection
If a compressor is malfunctioning (internal noise, insufficient cooling), check the compressor oil.
1.COMPRESSOR OIL JUDGMENT
Judgement result 1>>Replace compressor only.
Judgement result 2>>Replace
compressor and liquid tank.
Perform Oil Return Operation
CAUTION: If a large amount of refrigerant or oil leakage is detected, do not perform oil return operation.
Oil Adjusting Procedure for Components Replacement Except Compressor
Fill with oil for the amount that is calculated according to the following conditions.
Example: Oil amount to be added when replacing evaporator and liquid tank [m (US fl oz, Imp fl oz)] = 45 (1.5, 1.6) + 15 (0.5, 0.5) + α
Oil Adjusting Procedure for Compressor Replacement
No refrigerant pressure should be displayed. If NG, recover refrigerant from equipment lines.
If NG, refer to HAC-92, "Working with HFC-134a (R-134a)".
CAUTION: Do not add the 5 m (0.2 US fl oz, 0.2 Imp fl oz) of oil if only replacing the compressor and not the liquid tank.
