RECOMMENDATIONS AND SUGGESTIONS
The Instructions for Use apply to several versions of this appliance. Accordingly, you may find descriptions of individual features that do not apply to your specific appliance.
INSTALLATION -
The manufacturer will not be held liable for any damages resulting from incorrect or improper installation.
-
The minimum safety distance between the cooker top and the extractor hood is 650 mm (some models can be installed at a lower height, please refer to the paragraphs on working dimensions and installation).
-
Check that the mains voltage corresponds to that indicated on the rating plate fixed to the inside of the hood.
-
For Class I appliances, check that the domestic power supply guarantees adequate earthing. Connect the extractor to the exhaust flue through a pipe of a minimum diameter 120 mm. The route of the flue must be as short as possible.
-
Do not connect the extractor hood to exhaust ducts carrying combustion fumes (boilers, fireplaces, etc.).
-
If the extractor is used in conjunction with non-electrical appliances (e.g. gas burning appliances), a sufficient degree of aeration must be guaranteed in the room in order to prevent the backflow of exhaust gas. The kitchen must have an opening communicating directly with the open air in order to guarantee the entry of clean air. When the cooker hood is used in conjunction with appliances supplied with energy other than electricity, the negative pressure in the room must not exceed 0,04 bar to prevent fumes being drawn back into the room by the cooker hood.
-
In the event of damage to the power cable, it must be replaced by the manufacturer or by the technical service department, in order to prevent any risks.
-
If the instructions for installation for the gas hob specify a greater distance specified above, this has to be taken into account. Regulations concerning the discharge of air have to be fulfilled.

GENERAL INFORMATION – SAFETY WARNINGS
GENERAL INFORMATION
This canopy hood is designed to be fixed to any rigid vertical surface, over a gas or electric hotplate and can be used either in the extraction mode (ducted to the outside) or in the recirculation mode (internal recycling). All cookers hoods perform better when used in extraction mode. During winter time it may be convenient to use the hood in the recycling mode to avoid heat loss from the kitchen. Before starting the installation, consideration should be given to the difficulties that can be found during installation. The installation work must be undertaken by a qualified and competent person in conformity to the rules concerning the evacuation of contaminated air. The manufacturer disclaims all liability for any damage or injury caused as a result of not following the instructions for installation contained in the following text.
**SAFETY WARNINGS

USE – MAINTENANCE
OPERATION
3.1- Controls are located on the right-hand side of the front to operate
worktop illumination and select the most suitable working speed for your
cooking. To increase the area of extraction, the glass visor should be pulled
open. The top speed should be used when frying or cooking foods with strong
odours, while a lower speed can be used for normal cooking. To obtain the best
performance from your hood, turn it on before you start cooking and leave it
running for a few minutes after your cooking is over to clear the air.
3.2- Pay attention to safety regulations 1.7 and 1.8.
MAINTENANCE AND CLEANING
Regular maintenance and cleaning will ensure good performance and reliability
while extending the working life of the hood. Special attention should be
reserved to the grease filter and to the charcoal filter (recycling mode).
4.1 – Grease filter
This retains the solid grease particles and can be supplied in different
types. lt is fitted onto the reverse side of the metal grille panel.
Maintenance of the grease filter varies according to the user type. a-Whatever
type of filter used, the filter is easily removed from the grille by pushing
the metal wire clips to one side and removing them.
b-Thin synthetic filter (1 mm thick). It should not be washed and should be
replaced every two months. If the filter is provided with a saturation
indicator, replace it when:
b.1-The violet color of the dots, which are visible through the metal grille,
is spread over the whole surface of the filter.
b.2-The red color of the stripes, which is not visible through the metal
grille when the filter is clean, becomes visible from the outside of the metal
grille.
c-Multi-layer metal filter. It should be washed once a month in hot water
using a mild detergent or liquid soap. It can be washed in a dishwasher. It
should not be bent and should be left to drain dry.
WARNING: An excess of grease in the filter not only would affect the
performance of the hood, but it is also a possible fire risk. We strongly
recommend therefore cleaning and replacing filters in accordance with the
manufacturer’s instructions.
4.2 – Cleaning Metal self- supporting Grease Filters
- The filters are washable and must be cleaned at least every 2 months of operation, or more frequently for particularly heavy usage.
- Remove the filters one at a time by pushing them towards the back of the group and pulling them down at the same time.
- Wash the filters, taking care not to bend them. Allow them to dry before refitting.
- When refitting the filters, make sure that the handle is visible on the outside.
4.3 – Charcoal filter
The charcoal filter is a chemical filter to be used only when the hood is in
the recycling position. To replace the charcoal filter, open the grille and
remove the thumb screw through the centre of the charcoal filter. If the
filter is of the interlocking type, turn the filter anticlockwise. Replace by
reversing the operation. For good performance replace the charcoal filter on
average every three months.
4.4 – Worktop illumination
If a lamp fails to function at any time, open the metal grille panel and check
that the lamp is fully screwed into the holder. When changing the lamp, an
identical replacement must be fitted to ensure a safe working of the hood.
4.5 – Cleaning
The metal work should be cleaned regularly, at least once a month, using mild
household cleaner and polish. Never use abrasives. For all operations from
point 4.1 to point 4.4 and in particular for point 4.3, pay special attention
to the safety regulation 1.9.
