1. Safety
Danger!
Repairs may only be carried out by a qualified electrician!
Improper repairs can be extremely dangerous for the user.
It is essential that you observe the following instructions in order to prevent electric shocks:
• The casing and the frame may be live in the event of faults!
• Touching live components inside the appliance may cause dangerous currents to flow through your
body!
• Disconnect the appliance from the mains prior to carrying out any repair work!
• When inspecting live parts, a residual current circuit breaker must always be used!
• The earthed conductor resistance must not exceed the resistance specified in the standard! It is vital
for ensuring the safety of persons and the functioning of the appliance.
• On completion of repairs, an inspection must be carried out in accordance with VDE 0701
[Association of German Electrical Engineers] or in accordance with the corresponding regulations for
your country!
Make sure you observe the following instructions:
• The appliances must be disconnected from the mains prior to all repairs. If inspections must be
carried out on live appliances, make sure you use a residual current operated device.
Attention!
Sharp edges: Use protective gloves.
Components may be electrostatic!
Observe handling precautions!

2. General Information
A clearance of at least 30 cm must be maintained between the pan support area on the hob and the
bottom of the cooker hood. If the instructions for installation of the hob specify a larger clearance, this is
to be maintained.
The exhaust air ducts may not be connected to combustion exhaust gas chimneys (for example central
heaters, heaters, bathroom heaters, etc.).
Official regulations must always be observed the exhaust air is discharged. Furthermore, the exhaust air
may only be lead through a hole in the wall if the hole is intended for this purpose.
Attention!
Care must be taken when an extraction cooker
hood and a heating system operating on ambient
air (e.g. gas, oil or coal heaters, flow heaters or hot
water boilers) since extracting the air through the
cooker hood will remove the air from the room in
which these heaters are installed and which they
need for combustion purposes. Operation will only
be safe if, in the case of simultaneous operation of
a hood and a heater requiring ambient air, negative
pressure in the room in which the heater and the
hood are installed does not exceed 0.04 mbar, thus
ensuring that the exhaust gases of the heaters will
not be re-absorbed. The room must be fitted with
ventilation connections which ensure a constant
inflow of fresh air.
ATTENTION: This appliance must be earthed.
Make sure that the socket of electrical connections is earthed. In the case of electrical connection a
check will need to be carried out to ensure that the voltage level of the mains power supply complies with
the voltage levels indicated on the nameplate located on the inside of the appliance.If your hood has not
been fitted with a permanently connected cable with a plug or another device to enable universal
disconnection with a contact opening of at least 3 mm, suitable cut-off devices will need to be provided
for permanent connection. When installing the hood make sure that the plug is accessible if your hood
is fitted with a mains supply cable with a plug.
The hood must be disconnected from the mains power supply before it is cleaned or before any
maintenance work is carried out.

9. Faults and the cause
Attention!! Repairs may only be carried out by qualified electricians or specialists!
Problem Probable cause Solution
The cooker hood does not work. The power cable has not been connected to a live
socket. • Check to ensure that the cable has been properly inserted. Check to ensure that the
socket is live.
• Check the plug on the motor.
The light does not work. The lamp has burned out. Replace with the same model and reference.
The hood does not have enough power. Check whether
• The motor velocity selected is sufficient for the
quantity of smoke and steam which occurs.
• The kitchen has been sufficiently ventilated in
order to enable the air extraction opening to be
opened.
• The charcoal filter has been used up (air
circulation hood).
• The sensor is sufficiently sensitive (for hoods
with automatic operation).
The hood has gone off itself during standard
operation. Check whether
• There has been a power cut
• The universal switch has tripped.
