Precautions for Servicing Compressor

^ Attach a blind plug to the suction port (low pressure) and discharge port (high pressure) of the compressor to prevent oil from leaking out and dust from getting inside.

^ When the compressor Is removed, store It in the same position as it was mounted In the car.

^ When replacing the compressor, be sure to remove oil from the compressor and check the oil quantity extracted.

^ When replacing with a new compressor, be sure to remove oil from the new compressor so that the quantity of oil remaining in the new compressor Is equal to the quantity collected from the removed compressor. See the section "Lubrication OIL".

^ Pay attention so as not to allow dirt and oil to attach on the friction surfaces between clutch and pulley. if the surface is contaminated with oil, wipe It oft by using a clean waste cloth moistened with thinner.

^ After completing the compressor service operation, be sure to rotate the compressor shaft more than five turns In both directions by hand to equalize oil distribution inside the compressor, then run the compressor for about one hour by idling the engine.

It is important to understand that HFC-134a (R-134a) refrigerant, and the specified lubricant which must be used with HFC-134a (R-134a), must never be mixed with CFC-12 (R-12) refrigerant and/or the CFC-12 (R-12) lubricant.

This means that separate and non-interchangeable service equipment must be used for handling each type of refrigerant/lubricant.

To prevent the mixing of refrigerants/lubricants, refrigerant container fittings, service hose fittings, and service equipment fittings (equipment which handles refrigerant and/or lubricant) are different between CFO-12 (R-12) and HFC-134a (R-134a).

Adaptors to convert from one size fitting to the other must never be used: refrigerant/lubricant contamination will occur and compressor failure will result.
