The device can include at least one tank for coolant and a vacuum pump for generating a negative pressure in the vehicle air-conditioning system emptied of coolant or coolant/compressor oil mixture for a subsequent intake of coolant and optionally compressor oil into the vehicle air-conditioning system to be replenished. A chimney-like gas-collecting chamber having upper and lower openings can be arranged inside the service unit and is otherwise sealed off from the surrounding atmosphere.
