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 nonabrasive 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 (see note on page 8), 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.
To remove the grease filter
1. Pull open the handle on the grease filter as shown in fig. 2. It will
release at the handle side.
2. Lower the grease filter to remove it completely.
Fig. 2

8
To replace the grease filter
Repeat the steps on page 7 in reverse order.
Please note: Cleaning the grease filter in a dishwasher may lead to
discolouration. This is normal and does not constitute a fault with the
appliance.
Changing the charcoal filter (re-circulating only)
We recommend protecting any areas below and near the hob before
and during this process to make sure nothing falls and causes
damage.
To attach a new charcoal filter, first remove the grease filter as
described on page 7. Remove any old charcoal filter and then oer
up the magnetic side of the new charcoal filter to the metal extractor
housing/opening (the same that holds the grease filter) so that it
secures into place. Leave the tab on the filter accessible for when you
need to remove it. Then, replace the grease filter.
Charcoal filters are available as an optional accessory from CDA
Customer Care under code CHA12.

Changing the light
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.
Replaceable (LED only) light
source by a professional
LED LED
In case of malfunction of the illumination system contact the
technical service.

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.
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.

Installation - preparation
The extractor is intended to be mounted
directly to a solid ceiling using fixings
appropriate for the ceiling.
If the instructions provided with your gas hob state that the required
distance between the hob and extractor must be greater than 650mm,
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 under RIDDOR (The
height should be measured from the top of the burners).
IN THE ABSENCE OF ANY INSTRUCTIONS SUPPLIED WITH THE
GAS HOB, THE MINIMUM DISTANCE BETWEEN THE HOB AND
EXTRACTOR MUST BE AT LEAST 650mm.
The width of any hob must not be greater than the width of the
extractor installed above it.
Gas: 750mm recommended.
Electric: 650mm recommended.
Gas: 650mm recommended.
Electric: 600/550mm recommended.
Fig. 3
When the extractor is to be installed
above an electric hob, the minimum
distance between the hob and extractor
must exceed 600mm for ceramic and
solid plate hobs and 550mm for
induction Hobs.
When the extractor is to be installed
above a gas hob, the minimum distance
between the hob and extractor must
exceed 650mm.

13
Ducting
The ducting used should be 150mm, rigid circular pipe and must be
manufactured from fire retardant material, produced to BS 476 or DIN
4102-B1.
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.
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
pipe / valve using appropriate jubilee clips or securing means.

Installation
Note
•We recommend that you seek the
help of another individual when
installing this product. Always wear
adequate PPE (Personal Protective
Equipment).
•The fixings supplied are suitable
for most installations. It is the
responsibility of the installer to
ensure that the fixings are suitable
for the ceiling type in the property.
Installation steps
1. Using the supplied template, mark
the positions of the ceiling mounting
screws and the cut-out for the
ducting pipe, if required.
Fix four suitable wall plugs into the
holes and proceed to assemble the
extractor, as per fig 5.

A = Height of gas hob burner or electric
hotplate height from the kitchen
floor
B = Clearance required:
Gas hobs 750mm recommended
Electric hobs: 650mm recommended
A + B is the required height of the body
of the extractor above the floor.
Next you need to calculate the required
height of the extractor.
Whole extractor height = ceiling height -
height above floor (A+B).
3. Assemble the support sections 1, 2 3
and 4 on the diagram in fig 6, using
the supplied fixing screws and fix
to the chimney body. Measure the
height of the chimney and ensure
that it is equal to or less than the
height calculated in step 3. (When
the extractor is mounted the height
between the hob and extractor must
be at least the minimum height
specified). Connect the mounting
frame at the required height as per
Figs. 9 and 10.

4. Place the chimney sections over the body assembly, as shown in fig
7.
5. With the help of another individual, raise the whole assembly to the
ceiling and fix securely in place using four screws appropriate for
the wall plugs inserted in step 2. Ensure that the supporting ceiling
is strong enough to take the weight before releasing the extractor.
6. Connect the ducting to the extractor vent outlet, securing it in place
with a worm-drive hose clamp (jubilee clip).
7. Finally, raise the inner section of the chimney to the ceiling and
secure in place using the two small screws supplied
8. Note that the electrical connection to the extractor must not be
located inside the boundaries of the chimney. There must be an
isolation switch so that the extractor can be disconnected from the
mains electrical supply after installation.
