To change the charcoal filter
The activated carbon filter should only be used if you want to use the hood in the
recirculation function. This filter cannot be cleaned or reused, and as a rule the charcoal
filter should be changed once every four months.
Mount one carbon filter each on the
left and right so that the plastic grids
protecting the fan wheel are covered as
indicated. When ordering replacement
filters, always quote the hood model
ordering number and serial number. This
information can be found on the label on
the inside of this unit.
