| Oil Specification |
| 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.
|
| 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.

Replacement 1. Discharge refrigerant from refrigeration system. 2. Replace any faulty tubes or hoses. Cap the open fittings immediately to keep moisture or dirt out of the system.
Troubleshooting Problem Symptoms Table Before replacing or repairing air conditioning components, first determine if the malfunction is due to the refrigerant charge, air flow or compressor. Use the table below to help you find the cause of the problem.
Description The ambient temperature sensor is located inside the side mirror and detects ambient air temperature. It is a negative type thermistor; resistance will increase with lower temperature, and decrease with higher temperature. The sensor output will be used for discharge temperature control, temperature regulation door control,
