PRODUCT INFORMATION
Keep this book in a handy place for reference; it contains important details on the safe and proper
use of your appliance. Should you sell the extractor please remember to pass the instruction book
on to the new owner.
The extractor is designed to give you the option to extract air by ducting to the outside and away (via
an exterior wall), or to re-circulate through charcoal lters to minimise odours, steam and condensation.
The choice is yours to decide at installation, and both systems are explained in the booklet. We recommend
that you read this booklet thoroughly before attempting to install or operate the extractor.
The light on this appliance should only be used during operation of the cooker hood. It should not be left
on permanently and used as a lighting source.
PARTS IDENTIFICATION
On opening your box you will nd the extractor hood, a two-piece telescopic decorative chimney and a
bag of wall xings and screws, wall xing bracket, a ducting connector, and a wall xing template drawing.

METHODS OF EXTRACTION
The very best method of cleaning the kitchen of unwanted odours is by connecting the appliance to an
exhaust duct and venting to the outside atmosphere via the ceiling to an exterior wall. (Suitable ducting
kits may be purchased from the store where you bought your extractor.) You do not need a charcoal lter
when using the ducting mode.
Fig 1. Fig 2.
Ducting mode Recirculating mode
(No charcoal lter required) (Charcoal lters required)
REMEMBER: Before drilling or chiselling the ceiling or wall, check for pipes and power cables.
• Ensure the ducting tube is kept as short as possible and with the minimum of bends to permit the
smoothest airow. (Maximum length 3 metres.)
• Ducted air must not be discharged into a ue, which is used for exhausting fumes from appliances
supplied with energy other than electricity.
• 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 ow such as a central heating duct
We strongly advise that all exterior outlets be tted with a non return valve or louvered slatting.

ELECTRICAL CONNECTIONS
IMPORTANT: Ensure that the electricity supply is switched o before connecting.
Your appliance must be connected to xed wiring via the use of a double pole switched fused spur outlet
with at least 3mm contact separation, The isolation switch must be accessible after installation. (See
technical data for fuse rating).
We strongly recommend the appliance is connected by a qualied electrician who is a member of the
N.I.C.E.I.C. or Corgi who will comply with the I.E.E and any local regulations.
NOTE: The terminology DOUBLE POLE -/+ means that both the live and neutral supplies are switched and
disconnected at the same time.
The terminations labelled SUPPLY are for the connection for the internal house wiring and the
terminations labelled LOAD are for the connection for the appliance.
IMPORTANT: The wires in the mains lead are coloured in accordance with the following code:-
Blue..........Neutral
Brown......Live
As the colours of the wires in the mains lead of this appliance may not correspond with the coloured
markings identifying the terminals in your spur box, proceed as follows;
The wire which is coloured blue must be connected to the terminal which is marked with the letter ‘N’ or
coloured BLACK. The wire which is coloured brown must be connected to the terminal which is marked
with the letter ‘ L’ or coloured RED.

D) Selects motor speed 2. E) Selects motor speed 3.
WARNING: Never have a naked ame in direct contact with the grease lters or within the
extractor hood.
THE GREASE FILTERS
The grease lter is of a metallic material and should be
washed using a neutral detergent or in a dishwasher.
Removal of grease lters:
1 Press latch towards side of extractor
2 Lower lter to remove.
Fig 10.
THE CARBON FILTERS
Carbon lters have a limited life. We advise you to
change them when there is a noticeable drop in
performance. The intervals between changing the
lter will depend entirely upon the amount of cooking
you do, but on average they will last about 6 months.
To gain access to the carbon lters rst of all, remove
the grease lters as above. Remove the old lters and
reposition new charcoal lters (HJA2900 - pack of 2).

MAINTENANCE
IMPORTANT: Before cleaning or attempting any type of maintenance, always make sure that the
electric supply is disconnected.
To avoid the possibility of re, adhere strictly to all of the recommendations included in this booklet,
paying particular attention to the grease lters to ensure grease deposits do not build up.
NOTE: The manufacturer declines all liability in cases where the instructions for the appropriate
installation, maintenance and use of the extractor hood are not observed.
If the power supply is cut or damaged in any way, disconnect the extractor from the electricity supply and
call the service number on the rear cover of this booklet.
GENERAL CLEANING
Wipe the external surfaces of the appliance regularly using warm water and a mild detergent. NEVER use
abrasive cleaners.
REPLACING THE LIGHT BULBS
• Ensure that the power is switched o and the bulbs are cool.
• Remove the grease lters to gain access to the bulbs.
• Unscrew to remove the lamp and replace it with a new lamp of the same type and wattage.
NOTE: LAMP REPLACEMENT IS NOT COVERED BY YOUR GUARANTEE

Page 12www.howdens.com
TROUBLE SHOOTING
Before you assume the worst, check this simple fault-nding guide to get to the root of the
problem:
Lamps fail to operate?
• A replacement is probably necessary, but rst check that the lamp is correctly tted into its holder.
Remember that the light bulbs are not covered by our guarantee. Remember to disconnect the
mains electricity supply before replacing the lamps. Do not touch the lamps with ngers - use a
suitable cloth.
Motor is on but fan does not seem to be as ecient as usual?
• Check the grease lter. If it has not been cleaned recently, it might be clogged with grease. If this
lter is relatively clean, check carbon lters (if tted). If they have not been replaced for more than
six months, remove and insert new ones. As time goes by, accumulated grease tends to stie the
carbon lters in just the same way as the grease lter, thereby reducing the eciency of both the
fan and the lter itself.
Works normally but cooking smells linger?
• If you’re using the unit in recirculating mode, change the charcoal lter. It may require
replacement.
Appliance does not work at all?
• Check your extractor is switched on at the mains. Next, check there is power to your home by
switching on adjacent lights etc.
Still not working? Call the service
• If, having consulted the above diagnostics and you are still unable to remedy the situation, please
call the service number on the rear cover of this manual.
