  Note
t  The type of air conditioner compressor may differ depending on the production period and engine → Electronic parts catalogue.
t  The specified refrigerant oil capacities for the refrigerant circuit differ depending on the type of air conditioner compressor → Air conditioner with refrigerant R134a.
t  Different types of refrigerant oil are specified for Sanden, Delphi and Denso air conditioner compressors → Air conditioner with refrigerant R134a.
t  Not all replacement compressors have the same oil capacity. Therefore please observe the exact part number → Electronic parts catalogue and → Air conditioner with refrigerant R134a.
t  The different oil capacities result from the design of the compressor (observe oil capacities). Too much oil in the circuit results in higher pressures and a reduced cooling output of the system. Too little oil may lead to lubrication problems in the air conditioner compressor.
t  Always charge the refrigerant circuit as far as the upper tolerance limit (some refrigerant remains in filler hoses).
t  The refrigerant circuit is only to be filled with approved refrigerant oils → Electronic parts catalogue.
t  Refrigerant oil (PAG oil) from containers which have been open for a long time absorbs moisture and is no longer to be used.
t  For further information, refer to → Air conditioner with refrigerant R134a.
