HANDLING OF OIL
•
The oil should be free from moisture, dust,
metal powder, etc.
•
Do not mix with other oil
•
The water content in the oil increases when
exposed to the air. After use, seal oil from air
immediately.
•
The compressor oil must be stored in steel
containers, not in plastic containers.
COMPRESSOR OIL CHECK
The oil used to lubricate the compressor is
circulating with the refrigerant.
Whenever replacing any component of the system
or a large amount of gas leakage occurs, add oil to
maintain the original amount of oil.

Checking and Adjusting for Used Compressor
1) Perform Oil return operation.
(Refer to “Oil Return Operation” in this section.)
2) Discharge refrigerant and remove the
compressor.
3) Drain the compressor oil and measure the
extracted oil with a measuring cylinder.
4) If the amount of oil drained is much less than
90cc (2.5 Imp fl oz), some refrigerant may have
leaked out. Conduct leak tests on connections
of each system, and if necessary, repair or
replace faulty parts.
5) Check the compressor oil for contamination.
(Refer to “Contamination of Compressor Oil” in
this section.)
6) Adjust oil level following the procedure below.

7) Install the compressor, then evacuate, charge
and perform oil return operation.
8) Check system operation.
When it is impossible to perform oil return
operation, the compressor oil should be checked in
the following order:
1) Discharge refrigerant and remove the
compressor.
2) Drain the compressor oil and measure the
extracted oil with a measuring cylinder.
3) Check the oil for contamination.
4) If more than 90cc (2.5 Imp fl oz) of oil is
extracted from the compressor, supply same
amount of oil to the compressor to be installed.
If the amount of oil extracted is less than 90cc
(2.5 Imp fl oz), recheck the compressor oil in the
following order:
5) Supply 90cc (2.5 Imp fl oz) of oil to the
compressor and install it onto the vehicle.
6) Perform oil return operation.
7) Remove the compressor and recheck the
amount of oil.
8) Adjust the compressor oil, if necessary.
