Abstract: A process for operating a machine having a cab and an air conditioning system. The air conditioning system includes a circuit configured for supplying the cab with air coming from a recycling branch fed with air coming from an interior of the cab and an exterior branch fed with air coming from an exterior of the cab, a blowing device, and a filtration system. The process includes the steps of operating the air conditioning system in a regular procedure, monitoring of a signal indicative of a potential contamination of the cab, and upon the detection of such signal, operating the air conditioning system in a flushing procedure. The flushing procedure includes increasing the air flow supplied in the cab, controlling a flow of air to supply air only from the exterior branch, and opening an exhaust flap within the cab for increasing a flow of air evacuated from the cab.
