Use And Maintenance - Hafele HH-WG90A User Instructions

the cooker hood must be at least 65 cm. If a connection
tube composed of two parts is used, the upper part must be
placed outside the lower part. Do not connect the cooker
hood exhaust to the same conductor used to circulate hot air
or for evacuating fumes from other appliances generated by
other than an electrical source. Before proceeding with the
assembly operations, remove the anti-grease filter(s) (Fig.5)
so that the unit is easier to handle.
- In the case of assembly of the appliance in the suction version
prepare the hole for evacuation of the air.
• We recommend the use of an air exhaust tube which has the
same diameter as the air exhaust outlet hole. If a pipe with
a smaller diameter is used, the efficiency of the product may
be reduced and its operation may become noisier.
• Fixing to the wall:
Drill the holes A respecting the distances indicated (Fig.2). Fix
the appliance to the wall and align it in horizontal position
to the wall units. When the appliance has been adjusted,
definitely fix the hood using the screws A (Fig.4). For the vari-
ous installations use screws and screw anchors suited to the
type of wall (e.g. reinforced concrete, plasterboard, etc.). If
the screws and screw anchors are provided with the product,
check that they are suitable for the type of wall on which the
hood is to be fixed.
• Fixing the decorative telescopic flue - extractor ver-
sion:
Arrange the electrical power supply within the dimensions
of the decorative flue. If your appliance must be installed as
an extractor version, make sure an air exhaust hole has been
prepared. Adjust the width of the support bracket of the upper
flue (Fig.3). Then fix it to the ceiling using the screws A (Fig.3)
in such a way that it is in line with your hood and respecting
the distance from the ceiling indicated in Fig.2. Connect the
flange C to the air exhaust hole using a connection pipe (Fig.4).
Insert the upper flue into the lower flue. Fix the lower flue to
the hood using the screws B provided (Fig.4), extract the up-
per flue up to the bracket and fix it with the screws B (Fig.3).
To transform the hood from a ducting version into a filtering
version, ask your dealer for the charcoal filters and follow the
installation instructions.
• Fixing the decorative telescopic flue - filtering version:
- Install the hood and the two flues as described in the
paragraph for installation of the hood in ducting version. To
assemble the filtering flue refer to the instructions contained
in the kit.
- To transform the hood from the SUCTION version to the
FILTERING version, charcoal filters must be ordered from your
dealer as an accessory.
- There are two different types of kits available, one with non-
regenerable active carbon filters (Fig.6) and the other with
regenerable active carbon filters (Fig.7).

USE AND MAINTENANCE

• We recommend that the cooker hood is switched on before
any food is cooked. We also recommend that the appliance is
left running for 15 minutes after the food is cooked, in order
to thoroughly eliminate all contaminated air.
The effective performance of the cooker hood depends on
constant maintenance; the anti-grease filter and the active
carbon filter both require special attention.
• The anti-grease filter is responsible retaining the grease
particles suspended in the air, therefore it is subject to
clogging with variable frequency according to the use of the
appliance.
- To prevent the danger of possible fires, at least every 2
months one must wash the anti-grease filters by hand using
non-abrasive neutral liquid detergents or in the dishwasher
at low temperatures and on short cycles.
- After a few washes, colour alterations may occur. This does
not give the right to claim their replacement.
• The active carbon filters are used to purify the air that is
sent back into the room and its function s to mitigate the
unpleasant odours produced by cooking.
- The non-regenerable active carbon filters must be replaced
at least every 4 months. The saturation of the active charcoal
depends on the more or less prolonged use of the appliance,
on the type of kitchen and on the frequency with which anti-
grease filter is cleaned.
- Regenerable active charcoal filters must be washed by hand,
with non abrasive neutral detergents, or in the dishwasher at
a maximum temperature of 65°C (the washing cycle must be
complete without dishware). Remove excess water without
damaging the filter, remove the plastic parts, and let the mat
dry in the oven for at least 15 minutes approximately at a
maximum temperature of 100°C. To keep the regenerable
charcoal filter functioning efficient this operation must be
repeated every 2 months. These must be replaced at least
every 3 years or when the mat is damaged.
• Before remounting the anti-grease filters and the rege-
nerable active charcoal filters it is important that they are
completely dry.
• Clean the hood frequently, both internally and externally,
using a cloth dampened with denatured alcohol or neutral
liquid detergents that are non abrasive.
• The lighting .system is designed for use during cooking
and not for the prolonged general lighting of the room. The
prolonged use of the lighting system significantly decreases
the average duration of the bulbs.
• If the appliance is equipped with courtesy lights it is possible
to use them for general room lighting for a prolonged amount
of time.
• Attention: The non compliance with the hood cleaning
warnings and with the replacement and cleaning of the filters
entails risk of fires. One therefore recommends keeping to the
suggested instructions.
• Replacing halogen light bulbs (Fig.8):
To replace the halogen light bulbs B, remove the glass pane
C using a lever action on the relevant cracks.
Replace the bulbs with new ones of the same type.
Caution: Do not touch the light bulb with bare hands.
• Replacing LED lamps (Fig.9):
If the appliance version is with LED lamps, the intervention of
a specialised technician is necessary to replace them.
• Controls (Fig.10):
Button A = Switches the lights On/Off. The "filter alarm" can
be reset by pressing the button for a few seconds.
Button B = Switches the appliance on/Decreases the extrac-
tion rate of the motor. If the speed of the cooker hood is set to
1, it switches off. The appliance can be switched off by pressing
the "D" button for a few seconds.
Automatic extraction function: With this function the
appliance automatically adjusts the motor's extraction rate
according to the quality of the air below thanks to the sensor
located under the cooker hood (Fig.11).
To activate this function, press the "B" button for a few seconds.
The letter "S" will appear on the display.
