    What should be noted when retrofitting the vehicle?

    Checking / cleaning / replacing the components of the compressed air generation and preparation system; refer to the retrofit instructions for detailed information.

    How does the Voith SLS work and is there an explanation for noises?

    The Voith SLS is an idling system that switches the 1st compression stage to zero pressure when the air compressor is in non-conveyance mode. An external signal is not required for this. SLS switching is oriented to the pressure level in the pressure line. The function of the SLS generates a clocked mechanical noise in the non-conveyance mode.
