complies with all applicable legislation, including Gas safety, Electrical
safety (LVD) and Electromagnetic interference compatibility (EMC).
IMPORTANT INFORMATION FOR CORRECT DISPOSAL OF THE
PRODUCT IN ACCORDANCE WITH EU DIRECTIVE 2012/19/EU.
At the end of its working life, the product must be taken to a special
local authority waste collection centre or to a dealer providing
appliance recycling services.
Disposing of a household appliance separately avoids possible

Please note:
•Under no circumstances should the extractor be
connected to any gas ventilation system, flue system or
hot air ducting system.
• Do not vent the extractor into an attic or loft space.
•Only house the extractor in rooms with adequate
ventilation. Remember that the extractor is powerful and
whatever air is extracted needs to be replaced.
•Do not tile the extractor in. It should be removable for
service or maintenance.
•Do not use silicone sealant to secure the hood to the wall.
•You must be able to isolate the extractor from the mains
electrical supply after installation.
•This extractor has been designed to be used in a room
with a volume of less than 36m3.
•Steam cleaners must not be used when cleaning this
appliance.
•The performance of your extractor will vary depending on
a number of factors. These include type of extraction,
length of ducting, room volume, ventilation available and
cleanliness of the filters.

Care and maintenance
IMPORTANT: DO NOT PERFORM MAINTENANCE OR CLEANING
OF THE EXTRACTOR WITHOUT FIRST SWITCHING OFF THE
ELECTRICITY SUPPLY.
Cleaning
You should use a non-abrasive cleaner.
Any abrasive cleaner (including Cif) will
scratch the surface and could erase the
control panel markings.
You can clean your extractor eectively
by simply using a dilute solution of
water and mild detergent and drying to
a shine with a clean cloth.
Cleaning the grease filter
The grease filter should be kept clean
to minimise the risk of fire.
At least once a month you should
remove and clean the grease filter with
hot soapy water. You can also wash the
grease filter in a dishwasher, ensuring
that you place it in an upright position
to prevent damage from other items
in the dishwasher. After rinsing and
drying, replace the filter.

8
To remove the grease filter
To remove the grease filter, push in the button on the handle and then
pull down on the filter at the front as shown in figure 2. When you
have released it at the front, then you can pull the filter out completely.
Please note:
Cleaning the grease filter in the dishwasher may lead to
discolouration. This is normal and does not constitute a fault with the
appliance.
Changing the charcoal filter (re-circulating only)
To ensure best performance of your extractor, you should replace the
charcoal filters every four to six months, depending on use. To attach
a new charcoal filter, first remove the grease filter as described above.
Then oer up the charcoal filter to the side of the motor as shown in
figure 3 and turn it clockwise until it locks into place.

9
Changing a light bulb
DO NOT CHANGE THE LIGHT BULB IMMEDIATELY AFTER USE AS
THE BULB WILL BE HOT. ALLOW IT TO COOL BEFORE REMOVING
IT.
Remove the grease filter, unscrew the light bulb and replace the light
with the required light bulb as shown below. Finally, replace the
grease filter.
The ECH extractors are designed for 3W maximum LED 2 pin GU10
bulbs.
Do not touch bulbs or adjacent areas during or straight after pro-
longed use of the lights.
The light is designed for use during cooking and not for general room
illumination. Extended use of the light can reduce the life span of the
bulb.
Bulb replacement is not covered by the guarantee.
Only use bulbs recommended for your extractor. Do not fit bulbs of a
higher power rating. Bulbs of a lower power rating may be adequate
for use, generally last longer and use less energy.
Spare bulbs are available from CDA Customer Care or from your local
DIY shop.

Mains electricity connection
THIS APPLIANCE MUST BE CONNECTED TO THE MAINS SUPPLY
BY A COMPETENT PERSON, USING FIXED WIRING VIA A DOUBLE
POLE SWITCHED FUSED SPUR OUTLET AND PROTECTED BY A
3A FUSE.
We recommend that the appliance is
connected by a qualified electrician,
who is a member of the N.I.C.E.I.C. and
who will comply with the I.E.T. and local
regulations.
The wires in the mains lead of this
appliance are coloured in accordance
with the following code:
BLUE = NEUTRAL, BROWN = LIVE.
As the colours of the wires in the mains lead for the appliance may
not correspond with the coloured markings identifying the terminals
connecting to the fused spur, proceed as follows:
•The wire which is coloured blue must be connected to the terminal
marked N (Neutral) or coloured black.
•The wire which is coloured brown must be connected to the
terminal marked L (Live) or coloured red.

11
•If the mains cable is damaged, it must be replaced by a CDA
approved engineer, agent or similarly qualified person in order to
avoid a hazard.
NOTE: USE A 3A FUSE
Assembly and electrical connection should be carried out by
competent personnel.
When installing this product we recommend you seek the help of
another individual.
IMPORTANT: THIS APPLIANCE IS A CLASS II APPLIANCE
(DOUBLE INSULATED) AND IS NOT INTENDED TO BE EARTHED.
DO NOT FIT AN EARTH LEAD TO THIS EXTRACTOR.
Do not mount the isolation switch behind the chimney section. It is a
requirement that you must be able to isolate the extractor from the
mains electrical supply after installation.
This appliance is intended to be connected to the mains electrical
supply by means of an isolation switch and fused spur and is
intended to be protected by a 3A fuse. The use of a 13A fuse can
cause damage to the internal wiring in the event of a fault, and may
also invalidate the warranty.

Electrical information
Mains electrical voltage: 230 – 240Vac
Total rated power consumption: 146W
Troubleshooting
Please note:
Your extractor is equipped with a motor protection device that will
switch o the motor to prevent damage from overheating. This may
happen during cooking when most or all of the zones/burners are
being used simultaneously, or if your extractor is installed incorrectly,
lower than the recommended height.
This is normal, and the extractor will work again once the motor has
cooled suciently.
If your extractor is not working
1. Check that the mains supply has not been switched o.
2. Check that the fuse in the spur has not blown.
3. Contact CDA Customer Care

13
Mounting your extractor
When the extractor is to be installed
above an electric hob, the minimum
distance between the hob and extractor
must exceed 600mm (650mm is
recommended).
When the extractor is to be installed
above a gas hob, the minimum distance
between the hob and extractor
must exceed 700mm (750mm is
recommended).
If the instructions provided with your
gas hob state that the required distance
between the hob and extractor must be
greater than 700mm, then that is the
distance that should be observed; this
is a legal requirement and may lead to
your hob being disconnected from the
gas supply and the installation being
reported to RIDDOR (The height should
be measured from the top of the burners).

Ducting and ventilation
For best performance and lowest noise output, we recommend the
use of 150mm ducting. 125mm (or even 100mm) ducting may be
used but this will reduce performance and increase the noise of the
extractor.
Wherever possible utilise rigid circular pipe which has a smooth
interior, rather than the expanding concertina type ducting. The
lengths of ducting with minimal eect on performance are as follows:
• 4 metres with 1 x 90° bend.
• 3 metres with 2 x 90° bends.
• 2 metres with 3 x 90° bends.
Longer ducting can be used but the performance of the extractor will
likely be reduced.

17
Please note: Ducting components and ducting kits are optional
accessories and have to be ordered, they are not automatically
supplied with the hood. Use of ducting less than 150mm in diameter
will aect performance and increase the noise produced by the
extractor.
Note that the ducting should be secured and sealed to the vent outlet
using appropriate jubilee clips or securing means.
Installation for recirculation
When installing this extractor for re-circulating the air within your room
we advise use of the optional carbon filters to help remove odours.
You should change the filters every 6 months or less, depending
upon usage.
