The ventilation grilles must have an open
cross-section of at least 400 cm². This is
achieved by using the Dometic LS 330 absor-
ber ventilation and air extraction system which
has been tested and approved for this purpose.
Correct mounting of the lower ventilation grille
facilitates access to the connections and
functional parts during maintenance.
