Safety Instructions
Important note:
Please read this booklet before installing and switching on this appliance.
The manufacturer assumes no responsibility for incorrect installation and
usage as described in this booklet.
This appliance can be used by children aged from 8 years and above and
persons with reduced physical, sensory or mental capabilities or lack of
experience and knowledge if they have been given supervision or
instruction concerning use of the appliance in a safe way and understand
the hazards involved. Children shall not play with the appliance.
•Children should be supervised to ensure that they do not play with the
appliance.
•Children must not clean the appliance or carry out general maintenance unless
they are at least 8 years old and are being supervised.
•Keep children below the age of 8 years old at a safe distance from the appliance
and power cable.
•If the supply lead is damaged it must be replaced by a qualified person using
the correct lead, available from 0345 208 8750.
•The appliance can only be used safely if it is correctly installed according
to the safety instructions. The installer is responsible for ensuring that
the appliance works correctly after installation.
•This appliance is intended for domestic use and the household
environment only. The appliance is not intended for use outside.
•Do not leave the appliance unattended during operation. The
manufacturer is not liable for damage which is caused by improper use
or incorrect operation.
•Check the appliance for damage after unpacking it. Do not connect the
appliance if it has been damaged in transport.
•This appliance is not intended for operation with an external clock timer
or a remote control.

Safety Instructions
•Packaging material is dangerous to children. Never allow children to play
with packaging material.
•Risk of Death - Always ensure adequate fresh air in the room if the
appliance is being operated in extraction-air mode at the same time as
room air-dependent heat-producing appliance(s) are being operated.
•Room air-dependent heat-producing appliances (e.g. gas, oil, wood or
coal operated heaters, continuous flow heaters or water heaters) obtain
combustion air from the room in which they are installed and discharge
the exhaust gases into the open air through an exhaust gas system (e.g. a
chimney).
•In combination with an activated vapour extractor hood, room air is
extracted from the kitchen and neighbouring rooms –a partial vacuum is
produced if not enough fresh air is supplied. Toxic gases from the
chimney or the extraction shaft are sucked back into the living space.
•Adequate incoming air must therefore always be ensured.
•An incoming/exhaust air wall box alone will not ensure
compliance with the limit.
•Safe operation is possible only when the partial vacuum in the place
where the heat producing appliance is installed does not exceed 4 Pa
(0.04 mbar). This can be achieved when the air needed for combustion is
able to enter through openings that cannot be sealed, for example in
doors, windows, incoming/ exhaust air wall boxes or by other technical
means.
•In any case, consult your responsible Master Chimney Sweep. They will
be able to assess the house's entire ventilation setup and will suggest the
suitable ventilation measures to you.

5
Safety Instructions
•Risk of Fire - Grease deposits in the grease filter may catch fire. Clean the
grease filter at least every 2 months.
•Never operate the appliance without the grease filter.
•Grease deposits in the grease filter may catch fire. Never work with naked
flames close to the appliance (e.g. flambéing). Do not install the appliance near
a heat producing appliance for solid fuel (e.g. wood or coal) unless a closed,
non-removable cover is available. There must be no flying sparks.
•Hot oil and fat can ignite very quickly. Never leave hot fat or oil unattended.
Never use water to put out burning oil or fat. Switch off the hotplate. Extinguish
flames carefully using a lid, fire blanket or something similar.
•When gas burners are in operation without any cookware placed on them, they
can build up a lot of heat. A ventilation appliance installed above the cooker
may become damaged or catch fire. Only operate the gas burners with
cookware on them.
•Operating several gas burners at the same time gives rise to a great deal of
heat. A ventilation appliance installed above the cooker may become damaged
or catch fire. Never operate two gas burners simultaneously on the highest
flame for longer than 15 minutes. One large burner of more than 5 kW (wok) is
equivalent to the power of two gas burners.
•The accessible parts become very hot when in operation. Never touch hot parts.
Keep children at a safe distance.
•Components inside the appliance may have sharp edges. Wear protective
gloves.
•Items placed on the appliance may fall down. Do not place any objects on the
appliance.

6
Safety Instructions
•A defective appliance may cause electric shock. Never switch on a defective
appliance. Unplug the appliance from the mains or switch off the circuit
breaker in the fuse box. Contact the after-sales service.
•Incorrect repairs are dangerous. Repairs may only be carried out and damaged
power cables replaced by one of our trained after-sales technicians. If the
appliance is defective, unplug the appliance from the mains or switch off the
circuit breaker in the fuse box. Contact the after-sales service.
•Do not use any high-pressure cleaners or steam cleaners, which can result in an
electric shock.
•Always switch on the appliance while cooking to avoid condensation.
Condensation can produce corrosion damage.
•Always replace faulty bulbs to prevent the remaining bulbs from overloading.
•Risk of damage due to ingress of humidity into the electronic circuitry. Never
clean operator controls with a wet cloth. Surface damage due to incorrect
cleaning. Clean stainless steel surfaces in the direction of the grain only. Do not
use any stainless steel cleaners for operator controls.
•Surface damage due to strong or abrasive cleaning agents. Never use strong
and abrasive cleaning agents. Risk of damage from returning condensate. Install
the exhaust duct in such a way that it falls away from the appliance slightly (1°
slope).

Positioning
•This appliance is installed on the wall.
•Avoid damaging the product during installation
•The appliance can only be used safely if it is correctly installed according to the
safety instructions. The installer is responsible for ensuring that the appliance
works correct when installed.
•The width of the extractor hood must correspond at least with the width of the
hob.
•For the installation, observe the currently valid building regulations and the
regulations of the local electricity and gas suppliers.
•When conveying the exhaust air, official and legal regulations (e.g. state
building regulations) must be followed.
•The exhaust air must not be conveyed into a functioning smoke or exhaust gas
flue or into a shaft which is used to ventilate installation rooms that contain
heating appliances. If the exhaust air is to be conveyed into a non-functioning
smoke or exhaust gas flue, you must obtain the consent of the heating engineer
responsible.
•Always ensure adequate fresh air in the room if the appliance is being operated
in exhaust air mode at the same time as room air-dependent heat-producing
appliance is being operated.
All measurements in the below diagram are in millimetres (mm)

Operating modes
This appliance can be used in exhaust-air mode or circulating air mode.
Extraction-air mode
The air which is drawn in is cleaned by the grease filters and extracted outside by a
hose.
Important Notes:
•The extracted air must not be extracted into a functioning smoke, exhaust gas
flue or into a shaft which is used to ventilate installation rooms which contain
heat-producing appliances.
•Before the extracted air is extracted into a non-functioning smoke or exhaust
gas flue, obtain the consent of the heating engineer responsible.
•If the extracted air is carried through the outer wall, a telescopic wall box
should be used.
Circulating-air mode
The air which is drawn in is cleaned by the grease filters and carbon filters (carbon
filters are not supplied with your appliance) and extracted back into the kitchen.
Important Note: To remove odours in circulating-air mode, you must install a
carbon filters (carbon filters are not supplied with your appliance) . Please contact
our customer service team or visit https://mda.russellhobbs.com to purchase
carbon filter.
Dependent on use it is recommended that a carbon filters are changed every 2 –3
months.
