1. INTRODUCTION
During the cooking process, there will be heat, vapours and fumes
produced. Your Extractor has been designed to complement your
kitchen both in looks and performance in order to create a good
environment for creative cooking.
2. IMPORTANT INFORMATION
The exhaust air must not be discharged into a flue which is used
for exhausting fumes from non-electric appliances such as oil or
gas-fired central heating boilers or gas-fired water heaters, etc.
Requirements of the relevant authorities concerning the discharge
of exhaust air must be complied with.
Pay particular attention to fire risk when frying. To minimise the risk
of fire, all instructions relating to cleaning the grease filters and
removing grease deposits must be adhered to.
Do not flambé under the extractor.
The clearance between the hob burners and the bottom
surface of the cooker hood (extractor) should be within the
following range, unless a greater distance is specified by the
cooking appliance manufacturer:
Hob to underside of the cooker hood clearance distances:
•650mm minimum above electric hobs.
•760mm minimum above all gas hobs and gas or electric wok
burners, griddles, fryers, open grills / barbeques.
•850mm is the maximum recommended distance between the
hob and underside of the cooker hood.
The minimum distance between the hob and the bottom of the
cooker hood is essential for safety reasons and to prevent
overheating of the extractor and its components.
Exceeding the maximum clearance distance will reduce how
efficiently the cooker hood removes cooking fumes and odours.
You are advised to install measures designed to reduce the
incidence of cold draughts entering the property via any
ductwork.
For extractors with internal or inline fans, this should (at the very
least) consist of an external duct termination with integrated non-
return flaps (e.g. gravity shutter wall grille/louvre) and/or an inline
backdraught shutter.
For wall-mounted fans an inline backdraught shutter is
recommended.
3. EXTRACTION PERFORMANCE
The primary influence on the overall performance of the
extractor is the design of the ducting which takes the exhaust
air from the extractor to the outside. The duct route should be
a prime consideration during the initial stages of the kitchen
design (The manufacturer does not recommend recirculating
air back into the kitchen).
Please note the following:
•Easy access to the duct route during installation is
important. Lack of access may require the “blind” fitting of
flexible ducting, with increased risk of unseen kinks and
impaired efficiency.
•The extractor is provided with a spigot (or spigots) suitable
for connecting the ducting (Usually 150mm diameter).
Because this is a bespoke product, alternative
arrangements may have been agreed during the design
phase for connection of your ducting.
•Note: the cross-sectional area of the agreed duct size
should not be reduced as this seriously reduces extraction
efficiency.
•The most efficient configuration is to duct straight through
an outside wall so try to position the cooker against an
outside wall when designing your kitchen.
•If your extractor has adjustable exhaust positions then use
the exhaust position which gives the shortest achievable
duct route and least number of bends.
•Well installed, correctly sized rigid round ducting or an
equivalent flat channel system will usually perform best,
with round semi-rigid ducting being an alternative. Flexible
ducting is economical but its use should be minimised as it
gives the worst performance and should only be used for
short duct runs or initial connection and should be pulled
taut to prevent significant losses in extraction efficiency.
•For maximum efficiency, ducting should be kept as short
and as straight as possible with a constant cross-sectional
area being no less than that recommended by the
manufacturer. Bends in the duct will degrade performance
so the number of bends in a duct run should be kept to a
minimum and be gradual and smooth to prevent turbulence.
Avoid kinks in flexible ducting. Pulling the ducting taut over
straight runs will ensure that the internal surface is as
smooth as possible.
•If using rigid ducting you may wish to consider making the
initial duct connection to the extractor using semi-rigid (or
flexible, if unavoidable) round ducting to facilitate easier
installation and future maintenance.
If the duct spigot is accessible with the unit installed and it
will remain so in the completed kitchen (e.g. behind a
removable chimney) then no flexible connection need be
used.
•Ducting and associated components, including complete
kits are generally available.
WARNING
Proper care must be taken to ensure that the negative pressures
caused by high performance extraction systems do not adversely
affect the safe operation of certain types of fuel-burning
appliances (gas, oil or solid fuel), including those installed in the
kitchen and possibly those installed in other parts of the house.
Where such fuel-burning appliances are installed, adequate
ventilation MUST be provided in the room of installation, located
and sized such that the negative pressure in the room created by
the extractor does not exceed 4Pa.
In case of doubt, do not operate the extractor and fuel-burning
appliance(s) simultaneously and consult an appropriate (for the
fuel type) expert for advice.
ELECTRICAL SAFETY
This appliance requires an earth connection.
Ensure that the supply voltage corresponds to that marked
on the rating label inside the extractor.
The extractor must be isolated from the electrical supply
before carrying out any cleaning or maintenance operations.

4. INSTALLATION
To install the hood, it is necessary to remove the filters to gain
access to the wall fixing holes, and electrical supply cords &
connections.
General Installation
Remove the filters by opening the mechanical catch located at one
end of the filter.
Once the filters have been removed, locate the wall fixing holes
located at the rear bulk head of the appliance.
Duct Spigot Position
The appliance will be supplied with either a top outlet exhaust or a
rear outlet exhaust.
If the top outlet exhaust option has been selected, but the
ducting routes through a wall to the rear, then the installation
will require 215mm minimum head room in order to achieve a
smooth 90obend using 150mm flexible ducting.
Duct Installation
Install ducting taking note of the advice given in SECTIONS 2
and 3. It is recommended to use a length of semi-rigid ducting
for the final connection to the extractor spigot as this will allow
the unit to be pushed into final position with the duct connected.
If your extractor has multiple spigots, you will usually require
separate duct runs to the outside or to the remote fan(s).
If terminating on an outside wall, a suitable weather louvre
should be fitted. Various ducting components and complete kits
are generally available to suit most installations.
If using expanding foam, make sure any flexible ducting is
supported internally to prevent crushing.
For roof or chimney duct terminations, please seek specialist
advice.
Remote motors
Hoods intended for use with alternative remote fans will have
suitable provisions for their electrical connection (usually Live,
Neutral and Earth terminals, switched by the extractor) –these
provisions will usually be labelled to avoid confusion.
Note: Not all coloured terminals will be used because each
remote motor type is configured differently.
Some types of external fan may require a separate power
supply.
The fan should be installed in accordance with any installation
instructions that accompany it.
Fan extension kits for standard fans are generally available.
Alternatively, providing you use an electrician to carry out the
work, the cable can be extended using suitable flex. Ensure
that where the cable has been cut the numbered or coloured
wires are re-connected correctly
Detailed wiring illustrations and wiring instructions for
remote motors can be found on page 9.
This document provides detailed guidance for a typical
installation, however not all installations can be
accommodated within this guide.
If you are unsure how to proceed then please call Westin for
assistance.

Fixing the Extractor to the Wall
Fixing the extractor safely into position requires two people, so do
not start if assistance is unavailable.
Locate the fixing holes in the rear panel (as previously described).
Offer the hood up to the wall in the desired position and mark the
wall through the fixing holes. Ensure that the appliance is level.
Please be sure to check that any chimney previously removed can
be re-attached when the hood is secured in this position (adjust
position as necessary).
Secure the hood using suitable fixings (not supplied) in the
previously marked positions.
The supporting wall must be of good quality, have an even surface
and be sturdy enough to support the extractor.
Fixings must be used which are suitable for the type of wall
construction.
Connecting the Ducting
Terminate the ducting where it exits the building. If using a wall
mount weather louvre, secure the ducting to the louvre spigot
and attach the louvre to the wall. Ensure that the air fins are
directed downwards. If you are fitting an alternative termination
without a spigot, ensure that the ducting is secure.
If using expanding foam, make sure that flexible ducting is
supported internally to prevent it crushing or use rigid ducting
through the wall where foamed.
Install remaining ductwork ensuring any flexible ducting is taut
and smooth. Secure ducting to the extractor exhaust spigot(s)
using straps (e.g. jubilee clip). Do not use duct tape as the only
fixing.
Check that the duct has not been flattened or kinked.
•Electrical Installation
The extractor is a stationary appliance supplied with an
electrical supply flex and moulded 3 pin UK plug (3A) for
connection to the electrical supply.
The appliance must be fed from a 230Vac single phase
electrical supply. You may wish to terminate the electrical
supply using a standard mains electrical socket positioned
close to the extractors intended location.
Alternatively, you may terminate the electrical supply from a
switched-fused spur. The spur should be located adjacent to
the hood/cooker so that the supply can be disconnected from
the hood using the switch. The means of disconnection from
the supply must have a minimum contsact separation of 3mm
in all poles. A competent Part Pregistered electrical technician
must perform the electrical installation.
The mains supply is connected as follows:
INCOMING SUPPLY CORD CONNECTIONS
Core
Core Colour
Live
Brown

Make electrical connections for any remote motors, as
described earlier.
As a bespoke hood, it may be that other electrical connections
were agreed for your hood, such as connections to control the
lighting from elsewhere or to operate other electrical devices.
Make any remaining electrical connections now.
Finalise Installation
Finish the installation by re-fitting any parts previously removed
and attach any chimney / cladding panels or parts supplied
separately.

6. OPERATING INSTRUCTIONS
Radio Remote Controlled Models
•Switch on the power at the fused spur.
•Then Immediately turn on the remote control ( ).
•Then immediately press and hold ( ) until the lights illuminate.
Should the extractor fail to respond to commands from the remote-
control, please check that the power is ‘on’ and the internal
appliance reset switch is in the ‘ON’ position (factory default). The
reset switch is a latching red push-switch located in the chamber
behind the door panel / filter.
If you experience interference problems, or the remote appears to
be faulty from new, then a different radio transmission code may
be required.
Refer to the instruction leaflet included with the remote control
regarding transmission code changes before seeking assistance.
Refer to the instruction leaflet included with the radio remote
control console regarding pairing the device, transmission codes
and factory reset procedures.
Pushbutton Models
Other Control Systems
Because this is a custom-made product, an alternative control
system may have been specified during the design phase.
Most commonly this alternative control system will be a
continuously variable rotary fan speed controller plus light
control mounted on the extractor (usually the baseplate). With
most such control systems, you will find on/off switches for the
fan and lights and a rotating knob to adjust the fan speed.
Sometimes the switch and knob are combined into a single unit,
like a domestic lighting dimmer switch, which is pressed for
on/off function and turned for speed.
In some cases, the fan control may have been specified as a
separate item that does not form part of the extractor (e.g. a
wall mounted controller). Such controllers may have been
supplied by the manufacturer or a third party and are not
covered by this manual.
If you are unsure how to operate your unit then please call the
manufacturer for assistance.
The extractor controller will automatically switch off the
appliance if there has been no operator action for 4 hours.

7. MAINTENANCE
Regular maintenance is essential to ensure good performance
and long-life.
To maintain the immaculate appearance of the extractor, and
to minimise fire risk, ensure that grease deposits on the
extractor surfaces are kept to a minimum by regular cleaning.
To clean the stainless-steel surfaces of the extractor, use a soft
cloth and a suitable cleaning agent, such as a specially
produced stainless-steel cleaner or washing up detergent and
warm water.
Painted surfaces should be cleaned using a soft cloth,
detergent and warm water.
Glass surfaces should be cleaned with a suitable glass
cleaning agent.
Do not use abrasive cleaning materials or products.
Do not use bleach-based cleaning materials or
products.
Clean the grease filters in a dishwasher or by hand-washing in
hot water and detergent every 2 months - sooner if the extractor
is used extensively and filters become grease laden.
If your hood has mesh grease filters, you can expect years of
service from them however, they are considered a consumable
item and may deteriorate over time and need replacement,
particularly when cleaned in a dishwasher. For dishwasher
users adhering to a 2 monthly cleaning interval, we recommend
grease filter replacement every 5 years to maintain optimum
performance, even if they show no visible signs of deterioration.
For all users, filters should be replaced whenever they exhibit
signs of physical wear.
Removing the Grease Filters
Release the grease filter integrated sprung latch by pulling the
lever. Remove the filter. The filter is replaced by locating the
fixed tabs opposite the lever catch into corresponding slots in
the baseplate and then pushing the filter into position with the
latch held open. Once the filter is in position carefully release
the lever, allowing the latch to engage.
For units supplied with concealed filters, the filters are located
behind a hinged panel. This panel is held shut with magnetic
catches. Open the panel by grasping it in corners opposite the
hinged side.
LED lamp replacement
The long-life LED units are not designed for end user
replacement. In the unlikely event of failure please call the
manufacturer to arrange a Service Call.
Caring for HP4 high efficiency carbon filters
(Recirculating hoods only).
To restore and regenerate high efficiency HP4 carbon filters,
they must be washed in the dishwasher (without other dishes
or cookware) and then be placed into an oven for 1 hour at
max 90°C.
HP4 filters should be washed whenever they are dirty or lose
effectiveness (at least every two months).
Regular washing and regeneration will maximise the efficiency
and lifespan of these filters.
These filters can be regenerated repeatedly but are
considered a consumable and will eventually deteriorate, after
which they should be replaced. The time this takes will
depend on the style of cooking but they can be expected to
deliver excellent service under normal use conditions,
although replacement is recommended at least every two
years.
8. SPECIFICATIONS
A 3A fuse for the electrical supply is usually sufficient. Units
with multiple fans fitted may require a 5A fuse.
In all cases, because this is a custom made product you
must refer to the rating plate inside the extractor and any
remote motor and consult with your electrician to
determine the correct electrical supply fuse required to
protect you, your property and the appliance.
If your unit has been supplied to work with a remote or
third party fan then you should consult the rating plate of
both the extractor and fan(s) in order to determine the
electrical load of the system and size your fuse
accordingly.
