Installation
To fix the extractor to the kitchen unit.
The lower part of the extractor must be located at a minimum height of 60cm
above the hob for electric cookers and 65cm for gas cookers. If the
instructions of a gas cooker indicate a greater distance these must be
observed.
When the extractor is working at the same time as other non-electrical
cooking equipment, the outlet air pressure must not exceed 4 Pa.
To achieve optimum performance the length of the outlet hose should not
exceed 4 meters, or include more than two 90 angles (elbows)
Although venting to the outside is recommended, activated carbon filters may
be used, which allow the gas to be returned to the kitchen through the outlet
pipe.
