INSTALLATION
Unpacking
Care should be taken when unpacking the cooker
hood to ensure the fixing kit, ducting spigot and
literature pack are retained with the hood.
The fixing kit comprises of No 8 - 13mm fixing
screws
Positioning
When installed above an electric cooking ap¬
pliance the minimum distance between the sur¬
face of the hob elements and the lower grille of
the cooker hood must be 65cm (25 1/2").
When installed above a gas cooking appliance
the minimum distance between the surface of
the hob pan supports and the lower grille of the
cooker hood must be 70cm (27 1/2").
When installed above a cooking appliance with
a high level grill the minimum distance between
the upper surface of the grill and the lower grille
of the cooker hood must be 45cm (17 3/4").
The distance between the underside of adjoining
wall cabinets and the worktop must not be less
than 40cm (15 3/4").
Care should be taken when unpacking the cooker
hood to ensure that the fixing kit, ducting spigot
and literature pack are retained with the hood.
Fitting
IMPORTANT: Before fitting the hood beneath any
type of wall cabinet/ canopy housing ensure it is
firmly fixed to the wall in accordance with the
manufacturers instructions. Care should be taken
to check the wall to which the cabinet/canopy is
to be fitted for electric cables, water pipes or gas
pipes before drilling.
If it is necessary to fix the cabinet/canopy to a
hollow construction plaster or partition board
structure then it must be sufficiently reinforced to
be quite rigid in the area of the cabinet/canopy
mounting system.
Measure the underside of the cabinet/canopy to
mark the position for the cut-out as illustrated in
fig. 7. The cut-out should measure, width -
497mm by depth 261mm. Check the positioning
of the holes is correct with the measurements
above before making the cut-out.
The hood is fixed using the holes located in rim
around the cooker hood casing. Access to the
INSTALLATION Cont'd
screw holes will require the removal of the metal
grille panel. Press back on the two slide catch
fasteners located on the front edge of the grille,
which may then be pivoted down. Raise the hood
into the cut-out and mark the position for the
fixing screws. Pilot drill the fixing holes and fit
the hood using the fixing screws supplied having
ensured the ducting and mains supply cord have
been connected.
Recirculation
The hood is supplied specified for installation in
the extraction mode. To convert the hood to
recirculation it will be necessary to obtain the
(optional) charcoal filter. Charcoal filters can be
obtained by using the order form enclosed.
To fit the charcoal filter, open the metal inlet grille
as illustrated in fig. 3. Remove the screw from
the centre of the motor support grille and taking
the filter in one hand place it over the support.
Insert the screw with the other hand through the
hole in the centre of the charcoal filters as illus¬
trated in fig. 2 and finger tighten the screw until
the filter fits flush to the diffuser.
In the recirculation mode, contaminated air en¬
ters the cooker hood and passes through the
grease filter and charcoal filter and out into the
kitchen as illustrated in fig. 1.
When installed in the recirculation mode it will be
necessary for the installer to fabricate a chimney
from the ducting spigot on the top of the hood to
a terminal in the chimney/wall cabinet housing.
Ducting Fitting
Fit the ducting spigot into the aperture on the top
of the casing and make an air tight connection.
The ducting used must be 100mm (4ins) diam¬
eter, and where flexible ducting is fitted it should
not be turned through very tight bends as this
could impair the performance of the hood.
The ducting used must be 100mm (4ins) diam¬
eter and be manufactured from fire retardent
material conforming to the relevant British Stand¬
ard or DIN 4102-B1. (The maximum length of
ducting including one 90 Degree bend should be
3 metres, to be reduced by 1 metre for each 90
degree bend installed in the duct run).
The (optional) charcoal filter is not required when
the is installed in the ducting mode.
