-Before cleaning or performing any periodic or
urgent maintenance to the hood, isolate the
mains supply and turn the main switch off.
-Do not connect the hood to any piping used for
combustion appliances, such as burners, boilers
or fire places.
-Check that the main power supply corresponds
to the voltage required by the hood, which is
given on the silver label stuck inside the hood.
Ensure that the electric system is correctly
earthed and that the earth discharge works
correctly.
-When cooking do not use any materials that
could form high or unusual flames. Oil that has
been used twice and fats are very dangerous
and could easily catch fire. Do not prepare
flambé dishes under the hood.
-Once the specialised technician has completed
the installation of the hood equipped with a
remote motor, all the leads, connectors, ground
connections and the remote motor must not be
accessible to the user. Only the installer is
granted access by removing screwed on panel.
-Respect local legislation and regulations issued
by the relative authorities regarding the exhaust
air when the suction is operating. Failure to
respect and perform all maintenance and
cleaning operations described in this handbook
could cause a fire hazard.
ATTENTION: Accessible parts may become hot when
the hood is used with cooking appliance.
3. Installation
The minimum safety distance between the bottom of
the hood and the top of the cooking hob must be
650mm, smaller distances must be previously
authorised by the manufacturer. The maximum is
1.6m.
When the suction function is operating i.e. exhausting
the filtered air on the outside, a suitable
compensation system must be used according to
current standards in force. The diameter of the fume
exhaust pipe must be the same or greater than the
diameter of the hood pipe union.
There must be sufficient ventilation in the room where
the hood is installed, to allow simultaneous use of
other appliances that use gas or other fuels.
3.1 Assembly Instructions
Attention: Before proceeding with the installation,
make sure that the screws and the anchors supplied,
are suitable for the type of wall/ceiling the hood will be
fixed to.
To assemble the hood use the accessories that are
supplied and follow the instructions given in the
enclosed hand book.
Hanger Hooks
The Derwent has 4 hanger hooks at each corner to

motor and the external vent.
3.4 Electrical Wiring
The electrical wiring must be performed by a
specialised electrician fully respecting current
standards and legislation in force. Check that the
power supply corresponds to the voltage requested
by the hood, which is given on the silver label stuck
inside the hood. Ensure that the wiring system
conforms to current standards and the earth
discharge works efficiently. Pay special attention to
the hood power cable, ensure that it does not pass
through any holes without a cable clamp. For direct
connection to the electrical mains it is necessary to
provide a device that ensures disconnection from the
electrical mains, with an opening distance of the
contacts that allows the complete disconnection
under the conditions of overvoltage category III, in
accordance with the rules of installation. The plug or
Omni polar switch must be accessible when the unit is
installed.
If the power cord is damaged, it must be replaced by
a special cord or assembly available from the
manufacturer or its service agent. The cable must be
of type H05VV-F 3 x 0.75mm2minimum cross-section.
The manufacturer declines all responsibility if the
current accident prevention standards in force are not
respected, which are needed for the wiring system to
operate correctly.

4. Use & Maintenance
Before beginning any sort of cleaning or
maintenance work, turn the power off to the hood
by turning the main switch to 0 (OFF).
4.1 Cleaning the Metal Filters
The metal filters fitted in the hood should be washed
every 2-3 months, depending on how much the hood
is used, using hot water and a liquid detergent that is
not too aggressive.
The metal filters can be removed by the special
handle, unhooking the front part of the filter and
pulling it downwards (Fig 13).
Fig 13
4.2 Cleaning the Hood
The surfaces of the hood should be cleaned
frequently, to avoid the risk of having to remove built
up and encrusted deposits and stains.
For painted or copper plated hoods just a soft cloth
with warm water and a neutral detergent. Do not
pour the detergent directly onto the hood or use
powdery or abrasive products.
For stainless steel hood, use special products and
cloths for satin finish stainless steel (not abrasive,
corrosive detergents or detergents containing
chloride), ensuring to clean in the same direction as
the satin finish.
Do not use aggressive products, chemical solvents or
derivatives of oil distillates that could leave oily traces
which could cause oxidation and polymerisation.
The manufacturer accepts no responsibility for
damage to the surface of the hood due to failure to
respect these instructions.
