1. |
The HFC-134a system requires synthetic (PAG) compressor oil
whereas the R-12 system requires mineral compressor oil. The two oils
must never be mixed. |
2. |
Compressor (PAG) oil varies according to compressor model. Be sure to use oil specified for the compressor model.
|
Oil Handling
1. |
The oil should be free from moisture, dust, metal powder, etc. |
2. |
Do not mix with other types of oil. |
3. |
The water content in the oil increases when exposed to air.
After use, seal oil from air immediately. (HFC-134a Compressor Oil
absorbs moisture very easily.) |
4. |
The compressor oil must be stored in steel containers, not in plastic containers.
|
Compressor Oil Check
The oil used to lubricate the compressor circulates with the refrigerant.
Whenever replacing any component of the system or in case of a
large amount of gas leakage, add oil to maintain the original amount of
oil.
Oil total volume in system
PAG OIL : 120 ± 10cc (4.1±0.3oz.)

Oil Return Operation
There is a close affinity between the oil and refrigerant.
During normal operation, some of the oil recirculates with
the refrigerant in the system. When checking the amount of oil in the
system, or replacing any component of the system, the compressor must
run in advance for oil return operation. The procedure is as follows:
1. |
Open all the doors and engine hood. |
2. |
Start the engine and turn the air conditioning switch to “ON" and set the blower motor control knob at its highest position. |
3. |
Run the compressor for more than 20 minutes between 800 and 1,000 rpm in order to operate the system. |
