Engine, Starting With Empty Refrigerant Circuit When Necessary

If it is necessary to start the engine on a vehicle with an A/C compressor without a A/C Clutch -N25- with an empty refrigerant circuit.

• The refrigerant circuit must be fully assembled.
• There must be no vacuum in the refrigerant circuit.
• If the A/C compressor was removed: At least a quarter of the prescribed refrigerant oil amount must be in the A/C compressor.
• Engine speed must not exceed 2500 rpm.
• The engine should not be run for longer than absolutely necessary (for example, to move the vehicle into the workshop area).

If only the refrigerant was evacuated (the A/C compressor was not removed), it is guaranteed that there is enough refrigerant oil in the A/C compressor to continue lubricating the A/C compressor for a short operating period due to the design of the refrigerant circuit.
