INSTALLATION AND USER INSTRUCTIONS FOR
COOKER HOODS TYPE «EX 77» - «EX 77 TWIN»
These instructions should be read carefully
before the installation is done
Your new cooker hood can be used in the following ways:
Extraction (exhaust mode) - Fig. 1
In this case it is necessary to connect the hood to a tube (Ø
100"125 mm.) by using the connection piece which is supplied.
The extracted air is then expelled to the outside. Check that the
lever extraction/recirculation is in the position of Extraction (Fig.
3/B). For two motors turn the knobs A and B in the way as
indicated by the arrows (Fig. 4). For the evacuation of the
exhausted air please note ufficial instructions.
Recirculation (filtering mode) - Fig. 2
The air is purified by means of an active carbon filter (odour filter)
and then returned into the room. Check that the lever extraction/
recirculation is in the position of Recirculation (see Fig. 3/B),
that the top grid of the hood is not obstructed and that there is a
carbon filter fitted (see Fig. 3/C). For two motors turn the knobs
A and B like in the figure (Fig. 4).
Summer/Winter use
To avoid loss of heat in winter it is advisable to use the hood as
a recirculation hood. Warm air is purified and then re-distributed
into the room. Cooker hoods which are installed as extraction
hoods are easily changed to recirculation hoods and vice-versa.
Installation
The cooker hood must be fixed directly under a kitchen unit,
furthermore it must be installed centrally above the cooking hob.
The minimum distance between the hob and the lower part of the
cooker hood must be 650 mm.
N.B. The above distance is subject to regulations in force for
security in the respective countries.
Extraction Hood
When used in the extraction mode following points should be
considered: The exhausted air should not be conducted in a
chimney with warm air circulation. Do not connect the appliance
to fuel exhaust flues or ventilating ducts. With venting into exhaust
flues or ventilating ducts wich are no longer in use, it is advisable
to obtain the approval of the responsible agency for the building.
In the extraction mode the air is exhausted and conveyed through
the ventilating duct upwards or directly to the outside.
Attention: The shorter the exhaust duct is and the fewer bends
there are in it, the more effective will the cooker hood be.
Recirculation Hood
When the hood is used in the recirculation mode and fitted with
a carbon filter there is no need to connect the device (connection
piece) to the tube.
Installation under a Kitchen Unit
N.B. Check that the unit is able to support the weight of the
cooker hood.
Turn the unit upside-down.
Mark the holes for the screws.
Corresponding to the air-outlet a hole for the connection piece of
Ø 104/140 mm must be provided on the kitchen unit (for spigot
of Ø 100/125 mm).
Drill the holes for fixing the hood with a Ø 5 mm drill-bit.
Lean the unit against the top part of the cooker hood and tighten
it up to the hood with the 4 self-threading screws.
Connecting to mains supply
Check that the mains supply is the same as that on the technical
data plate which is attached to the cooker hood.
Attention: If the appliance has no plug an allpole separation
must be provided in the separation of the net with a minimum
contact width of 3 mm each pole.
Note — A damaged power supply cord must be changed by the
Service because require a special tool.
Maintenance
N.B. Before any repairs, servicing or cleaning is carried out the
plug must be disconnected.
The grease filter should be washed every 10-15 days in hot water
with detersive. It absorbs the particles of fat which become present
during cooking and protects the kitchen and its furniture from
deposits of grease. After successive washings however it should
be replaced.
The carbon filter functions during any type of cooking and is
highly effective removing cooking smells and particles of grease
which otherwise would be deposited on the walls and the fur-
niture. Carbon filters cannot be washed. It is advisable to replace
them every six months, depending on how frequently the hood is
in use.
In order to replace the filters mentioned above it is sufficient to
open the grid of the cooker hood by pushing the fixing devices
one towards the other pulling the grid outside until the control
board is freed. The grease filter can be taken off by removing the
retaining clips that hold it in its place, while the carbon filter can
be freed by turning counter clockwise.
The external parts of the cooker hood should be cleaned by using
a damp sponge and liquid neutral detersive or a cloth dipped in
neutralised alcohol.
Please avoid cleaning products that contain scouring agents.
Security regulations
Cooking «en flambe» under the cooker hood is forbidden. When
frying, constant watch must be given to all aspects of the ope-
ration in particular because oil heated to a high temperature
becomes inflammable easily.
Frequent cleaning, in particular of the fan and the surfaces of the
cooker hood, will avoid the risk of fire. The cleaning can be done
with a cloth or small brush dipped in ethyl alcohol. Furthermore
it is important to replace frequently each of the filters fitted in the
cooker hood.
Suggestions for the use in extraction mode
(exhaust version)
When the cooker hood is used in the extraction mode it is advisable
to give particular attention to appliances and sources of heating
at the same time in use (e.g. gas and oil heaters, coal or coke
fires etc.) because the cooker hood sucks in the air which is
needed for combustion by the above mentioned appliances causing
a depression.
During simultaneous use of heating appliances and cooker hood
a max. depression of 0,04 mbar is advisable. In these conditions
the risk of drawing in gases from heating appliances is avoided.
This can be obtained by openings which cannot be closed e.g. in
doors and windows or by other technical means. From these
openings sufficient fresh air for combustion should be able to
enter.
Attention: To assess the situation fully all flues and vents in the
apartment should be taken into consideration. If there is any doubt
then it is advisable to obtain the approval of the responsible
agency for the building. These precautions are not required when
the cooker hood is used in the filtering version with carbon filter
fitted.
