Cleaning and care
After cleaning
 After cleaning, leave the filter to dry
on an absorbent surface before
replacing it.
 When removing the filter for cleaning,
also clean off any residues of oil or
fat from the now accessible casing to
prevent the risk of these catching fire.
 First fit the top of the grease filter into
the slots at the top, then swing the
bottom of the grease filter into place
and press it into position.
