4. INSTALLATION
The Prime range of built-in extractors are designed to slot into
a cut-out/opening made in a horizontal soffit panel (usually the
underside of kitchen furniture or inglenooks / chimney
arrangements).
• The soffit panel into which the unit is to be fixed must
be between 15mm and 22mm thick.
4.1. Prepare Your Opening
Prepare the opening into which the unit will be installed.
Note: Should you need to reinforce your furniture around the
opening made then please ensure that the spring toggle clips
which support the unit when installed will still be able to spring
out and latch over the edge of your opening and hold the unit
securely in place.
4.2. Ducting Requirements and Installation
Make holes, as necessary, in the furniture, walls, or ceiling to
take 150mm round ducting (or an equivalent flat channel duct)
from the exhaust spigot location to the outside.
The duct route length should be kept as short as possible with
as few bends as possible (see Section 3).
Note: We recommend oversizing your duct holes by 25mm to
allow for any cables that may need to run alongside the duct
(such as remote motor or power cables) and to generally make
the installation of your ducting easier.
You should try to install all ductwork before fitting the extractor,
however, if this is not possible then all holes in walls or furniture
must be made in advance of fitting the extractor to avoid any
debris entering the appliance.
Regardless of the duct type being used for the majority of
your duct run, the initial duct connection to the extractor
spigot should be made using semi-rigid 150mm round
ducting. You should therefore terminate your duct in the
kitchen such that a length of semi rigid duct hangs down
through the opening in your soffit. This is important because
it will enable the ducting to be connected to the extractor
exhaust spigot before it is inserted into the furniture and allows
for easy removal and refit if service is ever necessary. It also
gives a degree of tolerance for any misalignment between the
extractor spigot and any fixed ductwork.
If terminating on an outside wall a suitable weather louvre
should be fitted. A variety of ducting components and complete
kits are available from Westin to suit most installations.
For roof or chimney duct terminations please contact Westin or
seek alternative specialist advice.
If you are fitting a wall-mounted external motor with semi-rigid
or flexible ducting, then you must leave a short length (approx.
200mm) of ducting proud of the wall, to enable connection to
the motor spigot, before pushing both back flush with the wall.
• Recirculating Models
Westin do not recommend recirculating air installations and
they should be avoided wherever possible.
If your extractor has been adapted for recirculation, (not the
standard configuration) then adequate provision must be made
for exhausted air to return into the kitchen after being expelled
from the extractor exhaust spigot. Adequate provision means
the air can travel back to the kitchen via means equivalent to
that of 150mm round ducting. This can be achieved, for
example, by ducting to a vent in the top of a cabinet (or
elsewhere in the room) or by creating an opening into the room
in the top of your furniture. Failure to allow the air back into the
kitchen will render the extractor ineffective, may cause the unit
to overheat and fail, and will invalidate your warranty.
4.3. Remote External Wall and Inline SEM Motors
If your extractor has been purchased to operate with a standard
inline or external remote motor (SEM), then you will find a black
plastic terminal box above the extractor, on a flying lead,
containing electrical terminals for connection to the remote
motor cable assembly. This box is referred to as the remote
motor terminal box.
Each terminal inside the remote motor terminal box has one
side connected to a coloured wire (which leads back to the hood
control system). The remote motor cable assembly also has
coloured wires and these are connected to the empty terminal.
Such corresponding colours are opposite and connect to each
other; i.e. red connects to red, blue to blue, and so on.
Not all terminals will be used as each remote motor type is
configured differently.
An electrician (or Part P registered electrical installer) should
undertake any work associated with the electrical installation of
SEM remote motors.
If you need to extend the remote motor cable then additional
cable can be purchased from Westin. Alternatively, it may be
extended using 7 core x 0.5mm flex. It is vital to ensure that any
new cable is inserted such that the core colour integrity is
maintained; i.e. a core that started as red must terminate as
red, blue as blue, purple as purple, and so on.
Any remote motor should be installed in accordance with the
installation instructions that accompany it. It must be installed
in an easily accessible location for future maintenance. Westin
are not responsible for providing the means of access (e.g.
scaffolding or any alterations to the building and/or furniture
necessary to make access possible) in the event of any
maintenance requirement.
No separate power supply is required for SEM remote motors.
