Duct Installation
Install ducting taking note of the advice given in SECTIONS 2 and
3. Westin recommend using 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
available from Westin to suit most installations.
If using expanding foam, make sure any flexible ducting is
supported internally to prevent it crushing.
For roof or chimney duct terminations, please contact Westin or
seek alternative specialist advice.

Recirculating Models
For recirculating installations, adequate provision must be made
for exhausted air to return into the kitchen (usually equivalent to
150mm round duct per fan) so do not block the vents provided.
Failure to do so may cause the unit to overheat and fail and will
invalidate your warranty.
Westin standard SEM and SEM EL remote motors.
Two styles of SEM motor are supplied, a pre energy label version
(SEM) and an energy label version (SEM EL) and each style is
wired differently.
•
For SEM 1,2,7 or 8 motors
, there will be a 6 pin socket and a
smaller two pin socket, usually mounted close to the spigot, for
connection of the fan. This socket may be inside the hood with
provision for bringing in the cable and plug
– alternative
provisions may have been agreed during the design phase.
The SEM1, 2, 7 or 8 fan comes with 5m of 6 core cable fitted
with a special 6 pin plug (on some models, a two pin plug).
•
For SEM 1EL, 2EL, 7EL or 8EL motors
, there is a black plastic
box, usually 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.
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 coloured terminals will be used because each remote motor
type is configured differently.
Detailed illustrations and wiring instructions for SEM EL
remote motors can be found on page 6.
Fan extension kits for standard SEM and SEM EL fans are
available from
Westin.
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.
Other 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.
The fan should be installed in accordance with any installation
instructions that accompany it.
No separate power supply is required for external fans supplied
by Westin.
Because this is a custom-made product, it may have been
specified to control a fan that has not been supplied by Westin.
Where this is the case the provision of power to the fan will
have been agreed during the design phase and in some
installations may require a separate power supply for the fan.
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 of the baseplate (as
previously described).
Offer the hood up to the wall in the desired position and mark
the wall through the fixing holes. 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 supplied in Westin ducting kits or a suitable
alternative, e.g. jubilee clip, do not use duct tape as the only
fixing.
Check that the duct has not been flattened or kinked
