Hanging Your Extractor
This instruction must be strictly adhered
to. Failure to comply could result in
overheating and serious damage to your
appliance. It is recommended that the
installation is carried out by two people.
 If ducting externally ensure the ducting tube is kept as short as possible and with the minimum
of bends to permit the smoothest airflow. (Maximum length 3 metres.).Ducted air must not be
discharged into a flue, which is used for exhausting fumes from appliances supplied with energy other
than electricity. (E.g. gas boilers)
Before drilling or chiselling the ceiling or
wall, check for pipes and power cables.
 Ensure the requirements of the local authorities are adhered to concerning the discharge of exhaust
air.
 Ensure adequate room ventilation is provided when the extractor is used in the same room as
appliances supplied with energy other than electricity.
 Never duct into a hot air flowsuch as a central heating duct
We strongly advise that all exterior
outlets be fitted with a non return flap
or louvred slatting.
 Remove the grease filters before trying to install.
 Mark and drill the holes required to mount the extractor body.
 The principal securing point is the top keyhole slot; fix this screw first leaving approximately 5mm
between the screw head and the wall.
 With the help of an assistant, level and secure in position through the lower two holes tightening the
upper screws as necessary.
 The recommended fixing height for the hood is750mm above the worktop. This canbe reduced to a
minimum of 700mm if required.
