Pull flexible ducting back along its route such that it is as
smooth as possible. Position the extractor face down and
as close to the opening as is practical and cut off excess
before connecting the ducting to the extractor exhaust
spigot using plastic tie straps or a suitable alternative (e.g.
jubilee clip) - do not use duct tape as the sole means of
connection.
Note: The FM900 has integral non-return flaps as part of
the spigot assembly to reduce air blowing back into the
unit from outside. Take care not to obstruct these flaps
when connecting flexible ducting. The flaps are designed
to supplement the provisions you make in your ductwork
to prevent draughts. You may remove these flaps if you
are worried that they will catch on your ductwork, provided
that other measures to control draughts have been
installed.
Check that the duct has not been flattened or kinked.
4.5 Fixing the Extractor in Position
Fixing the extractor safely into position requires two
people so do not start if assistance is unavailable.
Remove the grease filters to prevent damage whilst
manoeuvring the product.
Fixing holes are located in the extractor fixing flange –
see Section 8 (Page 10) "General Arrangements
Drawing". The extractor is held securely in place by
screws into the soffit panel through these holes.
Check that the electrical supply chord has been
connected, that power is switched off and that the
ducting is securely fastened to the spigot.
Push the extractor up through the prepared opening
and mark the positions of the fixing holes.
Take care not to crush or introduce undesirable
bends/kinks in the ducting when pushing the extractor
into place.
Because the fixing holes are close to the edge of the
soffit cut-out it is recommended that pilot holes are
drilled for the fixing screws.
Secure the extractor in place using the screws supplied
or suitable alternatives for your panel and cut-out
arrangement.
One person should hold the unit in place whilst pilot
holes and screws are installed by an assistant – do not
attempt this on your own.
Note: Consider whether you can build in provisions for
accessing the ducting and top of the cooker hood after it
is installed in your furniture - this may simplify installation
and improve performance by allowing the ducting to be
connected and straightened after the hood is in position
and will enable easier inspection and removal of the unit
in the event of future service need.

The blower transport ties can now be removed (if fitted)
– see picture below. Note: These are only there to
protect the motor from careless handling in transit.
Should you wish to remove the extractor then two
people are required to safely undertake this work.
The removal process is the reverse of installation.
One person should hold the unit and prevent it falling
whilst an assistant removes the screws securing it in
place.
Once the screws are removed both people can
carefully lower the appliance from the opening, taking
care not to damage the extractor or ducting in the
process.
Tip: You may wish to position a platform on the hob (such
as the hood box) to place the extractor on, because the
connected ducting may not be long enough to reach the
work surface.
