4.5. Ducting
Install ducting taking note of the advice given in section 2 & 3.
We recommend using semi-rigid round ducting for this
extractor – the initial connection to the extractor spigot must
be in semi-rigid (or flexible duct) to allow the entire unit (or top
box if fitting separately) to be pushed into position with the
duct connected.
Run the ducting such that there is enough to easily reach just
beyond the centre point of the extractor, thus allowing for a
short length to be pulled through the opening for later
connection to the top box spigot. Try to avoid tight bends
immediately adjacent to where the top box will be as this will
make pushing the unit/top box into position more difficult.
When terminating ducting on an outside wall, a suitable
weather louvre should be fitted. Various ducting components
and complete kits are available from
Westin
to suit most
installations.
If you plan to use expanding foam, make sure that any soft
flexible ducting is supported internally to prevent it crushing, or
use semi-rigid/rigid ducting where foam is used.
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 expanded (stretched out) ducting proud of the wall
(to facilitate connection to the motor spigot) before pushing
both into position flush with the wall.
Standard external motors come with a cable assembly and
fitted plugs that must pass through the wall and run back to
the extractor – usually this passes alongside the ducting so it
is recommended to oversize your cut-out by at least 25mm to
allow for this (and for the easy installation of the duct).
4.6. Remote External Wall and Inline 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 box outside the extractor (on flying leads)
containing electrical terminals for connection to the remote
motor cable assembly. This box is referred to as the remote
motor terminal box.
Run the remote motor cable such that sufficient hangs down
through the ceiling opening prepared for the extractor to allow
for easy connection to 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
terminals. 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 because each remote motor type
is configured differently.
No separate power supply is required for the external motor.
An electrician (or Part P registered electrical installer) should
undertake any work associated with the electrical installation
of SEM remote motors.
Please refer to the
REMOTE MOTOR ILLUSTRATIONS
on
page 9 for more information.
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.
4.7. Electrical Installation
The extractor is a fixed electrical appliance and must have a
provision for isolating the electrical supply via a switched-
fused spur located in an accessible position within the kitchen.
A qualified electrical technician must perform the installation of
the electrical supply to the extractor.
The hood must be fed from a dedicated 230Vac single
phase electrical supply
terminated with a switched spur
fitted with a 3A fuse. The switch should be located so that the
supply can be disconnected from the extractor using the
switch at any time following installation – the switch must be
accessible. The means of disconnection from the supply must
have a minimum contact separation of 3mm in all poles.
Alternatively, a means of disconnection in the fixed wiring
according to the relevant wiring rules must be fitted.
A supply cord for connecting the extractor to the spur is
included.
The mains supply is connected to the free end of this
cord as follows:
INCOMING SUPPLY CORD CONNECTIONS
Core
Core Colour
Live
Brown
Neutral
Blue
Protective Earth
Green/Yellow
For your convenience during installation, we recommend
terminating the electrical supply from the switched - fused spur
with a standard UK 3 pin 240V socket, positioned close to the
extractors intended location. The extractor's electrical supply
cord can then be fitted with a standard 240V 3 pin plug for
easy connection to the supply during installation.
Make sure the switched - fused spur supplying the extractor is
in the ‘off’ position before connecting the appliance to the
electrical supply.
4.8. Fixing the Extractor in Position
Please note the following prior to commencing fixing the
extractor in position:
You will need at least 2 people to fit this extractor; to lift,
hold and fix the unit in position:
A working platform or scaffold should be used so that the
ceiling opening can be reached and the unit fixed without
the use of ladders.
