R8 Quattro Coupe V10-5.2L (BUJ) (2010)
Refrigerant: Description and Operation
Capacity Information
Evacuate and fill the refrigerant circuit.
-
Operate the A/C system after filling the refrigerant circuit, refer to => [ Operating After Filling Refrigerant Circuit ] See: Heating and Air
Conditioning/Service Precautions/Technician Safety Information/Heating, Ventilation & Air Conditioning.
‹› When charging the A/C system, always use maximum amount of refrigerant R134a, as some of the refrigerant remains in the hose of the refrigerant
recovery, recycling and recharging unit.
‹› The refrigerant circuit may only be filled with approved refrigerant oils.
‹› Use only the specified oil from a sealed container and always reseal oil container immediately after use (PAG oil absorbs moisture). Do not use oil
if it is contaminated with moisture or if oil container has been left open.
‹› Depending on the type of A/C compressor, different refrigerant oil capacities are intended for the refrigerant circuit.
‹› Compressor as replacement part has different oil fill capacities, therefore note the exact part number. The reason for the different oil capacities in
the compressor is the design of the compressor itself, note these oil capacities. Too much oil in the circuit leads to higher pressures and reduces
cooling performance of the system. Too little oil may lead to lubrication problems in the compressor.
