HFC-134a (R-134a) Service Tools and
Equipment
Never mix HFC-134a refrigerant and/or its speci®ed lubricant with CFC-12 (R-12) refrigerant and/or its lubri-
cant.
Separate and non-interchangeable service equipment must be used for each type of refrigerant/lubricant.
Refrigerant container ®ttings, service hose ®ttings and service equipment ®ttings (equipment which handles
refrigerant and/or lubricant) are different between CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid
mixed use of the refrigerants/lubricant.
Adapters that convert one size ®tting to another must never be used: refrigerant/lubricant contamination will
occur and compressor failure will result.
