Filters and maintenance
Metal grease filter:
The filter mat is made of non-combustible
metal.
Caution:
As it becomes more and more saturated
with grease, the filter also becomes
increasingly inflammable. The efficiency of
the extractor hood can also be adversely
affected.
Important:
By cleaning the metal grease filters at
appropriate intervals, the possibility of them
catching fire as a result of a build-up of heat
such as occurs when deep-fat frying or
roasting is taking place, is reduced.

Cleaning the metal filter:
Under normal operating conditions (1 to 2
hours per day), the metal grease filter will
require cleaning after 8 to 10 weeks.
❑ The filter can be cleaned in a
dishwasher.
This can however cause slight
discoloration.
Important:
Metal filters that are heavily saturated
with grease should not be cleaned at the
same time as any crockery, etc.
❑ If the filter mat is going to be cleaned by
hand, soak it first of all in a hot detergent
solution for several hours.
Clean the filter with a brush, rinse it off
thoroughly and allow it to drip dry.
❑ Use only original replacement filters.
In so doing you will be ensuring that the
extractor hood performs as effectively as
possible.
Removing/inserting the metal grease
filter:
