Abstract: A device for maintaining an air conditioner, in particular, for air conditioners using CO2 or R744 as a coolant. The device has a low-pressure side region (A), which is connectable to a service port on the low-pressure side of the air conditioner via a low-pressure side coupler (1), and a high-pressure side region (C), which is connectable to a service port on the high-pressure side of the air conditioner via a high-pressure side coupler (1′). A compressor (4) is provided between the low-pressure side region (A) and the high-pressure side region (C) and between the compressor (4) and the high-pressure side region (C) an over-pressure region (B) is provided, which is connected to the high-pressure side region (C) via a throttle device (5).
