When the alarm sounds, the fan is activated either manually or automatically. The exhaust pipe is placed into the Channel duct system, so that the exhaust fumes are extracted into the system. A connector is placed on the exhaust pipe, which ensures that only the exhaust fumes are extracted.

When the vehicle drives from the garage, the exhaust pipe slides inside the Channel duct system, and the polluted air is extracted.

The inlet guide is placed at the end of the channel duct. When parking the vehicle, the exhaust pipe should be aimed toward the inlet guide, and then the channel duct follows the exhaust pipe. If the vehicle is not completely parallel with the channel duct, the duct is simply pushed in the same direction as the vehicle.
