Correct use

Open flames are a fire hazard.
Never use an open flame beside the downdraft extractor. To avoid
the danger of fire, do not flambé or grill over an open flame. When
switched on, the downdraft extractor could draw flames into the
filter. Fat deposits could ignite, presenting a fire hazard.

Overheated oil and fat can ignite, causing fire damage to the
downdraft extractor.
When cooking with oil or fat, chip pans and deep fat fryers, etc, do
not leave the pots and pans unattended. Similarly, never leave an
open grill unattended when grilling.

Deposits of grease and dirt will prevent the downdraft extractor
from working properly.
Do not use the downdraft extractor without the grease filters in
place. Otherwise cooking vapours will not be cleaned.

Hot cooking vapours during cooking can cause the downdraft
extractor to get hot.
Do not touch the casing or the grease filters until the downdraft
extractor has cooled down.

Do not use the downdraft extractor for resting objects on.

Liquids can damage the downdraft extractor if they get into it.
Keep liquids away from the downdraft extractor.

Light objects can be drawn into the downdraft extractor and
impair its operation.
Do not place any light objects (e.g. paper towels) within close
proximity of the downdraft extractor.

If you are operating a gas cooking element directly next to the
downdraft extractor, the FlameGuard must be placed between the
downdraft extractor and the element.
