2. Important Safety Information
Product Use
This product is designed for household use and should not be used for commercial applications.
After use, always ensure that all controls are in the “OFF” position.
When frying with a gas ame, take particular care not to allow the oil or grease in the pan to catch
re. (Flambé)
Ducted or Recirculating?
Ducted rangehoods (or extractor rangehoods) extract the cooking fumes from the kitchen and expel
them from the space via ducting. Good design practice would always see a re-rated ducting system
extend to the house exterior, rather than to the ceiling cavity. When a rangehood is ducted only into
the ceiling space, the collection of humidity and grease can present very real health issues and re hazards.
Recirculating (or non-ducted or ltered) rangehoods extract cooking fumes and pass them through
lters. As the name would suggest, they recirculate this air back into the room. Recirculating rangehoods
are not as eective as removing fumes from a kitchen space, but they are sometimes the only option due
to budgetary or building constraints. You should be made aware of the requirement to change and clean
lters on a regular basis for the optimum eciency of air ltering.
Electrical Cord
Ensure the supply cord is not exposed to heat, chemicals or sharp objects. If the supply cord is damaged,
it must be replaced by the manufacturer.

4. Operation
Schweigen silent rangehoods are recognised for their silent operation. Although this holds true for all
of our rangehoods with external motors, one must note that the rangehoods are silent when they are
used for regular cooking on the lower fan setting. Therefore, you will only hear the movement of air.
Electronic Control Panel
A. Timer: When this function is activated, the blue light will ash on the timer button. The rangehood
continues to operate for 10-15 minutes at the required speed and then automatically switches the
motor o.
B. Increase speed: This button increases the aspiration speed. When at maximum speed, the blue
light will ash.
C. ON / OFF: This button turns the rangehood on and o. The rangehood will always turn on at the
same speed at which is was turned o.
D. Reduce speed: This button reduces the aspiration speed. When in operation, the low speed button
will be blue.
E. Light: Press this button to turn the lights on and o. When the lights are operating, the light button
is blue.
This rangehood has a device that lets you know when the grease lters must be cleaned.
When the light button (E) ashes, this means the lters must be washed (usually after 40 hours of
operation).
When the lters have been washed and re-mounted, hold the light button (E) down for a few seconds to
reset it and return the counter down to zero.
Speed Control
This rangehood is equipped with a 4 speed electronic control. Speed control usage suggestions:
• Low speed for simmering.
• Medium speed for light cooking.
• High speed for heavy frying or heavy cooking.
To obtain the best performance, switch the rangehood on a few minutes prior to cooking and leave
it running for at least 10 minutes after you have nished cooking.

Cleaning the Interior
Clean the interior of the rangehood with a damp cloth and a neutral detergent or denatured alcohol.
NOTE: Do not use denatured alcohol on the exterior of the rangehood. Do not clean the electric parts or
the motor with liquids or solvents
Cleaning the Exterior
We recommended using a soft cloth, water and a liquid soap, rinsing it well and then drying it thoroughly.
For better results, you can use high quality cleaning and protection products (e.g. Steel Kleen) to clean
your rangehood.
• The recommended detergent is a solution of water and a neutral
liquid soap.
• It is very important for the liquid soap to not contain granules
that could scratch the surface.
• First apply the solution to a soft cloth and then rub the cloth
over the rangehood. It is important to follow the direction of the
stained surface with the cloth (refer to gure on left).
• Do not pour any liquid directly on to the rangehood.
• The cloth must have no buttons, zips or fasteners that could
scratch the surface.
• It is strictly forbidden to use chemical solvents, aggressive,
grainy or abrasive products, naphtha, alcohol or similar products
that could damage the surface of the rangehood.
• The manufacturer will not be held responsible for functional or
aesthetic damage caused by cleaning with products which are
not suitable or using inadequate cleaning methods.

5. Cleaning & Maintenance
Filters
For this appliance to function eectively, regular maintenance is a must.
• The function of the lter is to absorb the grease particles given o during cooking.
• Clogged lters and heavy oil deposits restrict airow and may cause the motor to overheat
and become a re hazard.
• Filters should be cleaned every 3-6 weeks or after 40 hours of use.
• For induction cooktop, please aim to clean them at least every 10 days, depending on use.
• The lters can be washed by hand or in the dishwasher.
–Washing by hand - Immerse the lter in hot water and a suitable detergent and when clean,
rinse with plenty of hot water.
–Dishwasher - Put the lter in the dishwasher and select a short program at low temperature.
NOTE: The colour of the metal mesh lters may change after several washes. This is normal and
it is not necessary to change the lters.
Please ensure the lters are completely dry before placing them back in position
and operating the rangehood.
Warning
• If the grease lters are very dirty, the motor will extract only a small quantity of air,
which reduces its eciency;
• The grease deposits that build up on the lter are highly ammable and COULD
EASILY CATCH FIRE.
• The manufacturer is exonerated from all responsibility in the event of re due to poor
maintenance of the grease lters.
To remove the lter press handle and remove
it through the front guide; bend it slightly and
remove lter. To replace, perform the same
operation but in reverse.
If your rangehood is equipped with the Balanced
Aspiration System, periodical cleaning is required.
The Balanced Aspiration plate can be removed
by taking out the 6 screws as shown. Please
make sure it is fully dry before installing back
to the rangehood.

Mounting Instructions
It is STRONGLY RECOMMENDED that the rangehood be installed centrally over the cooktop.
This will greatly improve its performance.
Minimum height from the hob top surface to the underside face of the rangehood:
• 650mm electric cooktop
• 650mm gas cooktop
Any installation above 800mm will compromise the extraction performance.
Note: If the instructions for the gas cooktop specify a greater distance, this must be taken into account.
Recommended Installation Height for Induction Cooktop
To help avoid condensation, particular to cooking with an induction cooktop, Schweigen recommends
a height between 700-750mm. Refer to page 19 for further information.
*IMPORTANT: If the user decides to install the rangehood
at a distance of less than minimum height above the cooking
surface, Schweigen declines responsibility for damages
suered by the rangehood due to excess heat or damage
to objects, people and others caused directly or indirectly
by a malfunction, breakage or re.
Measurements are from the top of the trivets
to the lowest part of the rangehood, including
the button controls.
*Important: In addition to the information in this manual,
please check all relevant state requirememnts for minimum–
maximum heights, as well as regulations regarding the
expelling of air. Schweigen is not liable if your rangehood is
not installed in accordance with these legal requirements.

Ducting
Please DO NOT crush or kink the ducting.
1. Crushed or kinked ducting creates
sharp corners that creates turbulence.
This reduces the size and eciency
of the ducting, lowers extraction and
may cause excessive noise.
2. Sweeping curves and taut ducting
reduces resistance and turbulence.
The airow and extraction will be
more ecient and stronger.
Back Draft Fins (For applicable models)
The supplied ducting has been manufactured with an allowance for the back draft ns to operate without
hindrance. It is the smooth extended end of the ducting.
When installing Back Draft Fins, please ensure that you insert the Back Draft Fins onto the back draft base,
which are attached to the top of the motor outlet before installation. Then place the smooth extended edge
of the ducting into the back draft base and x securely.
Should your Back Draft Fins get stuck, this is not a warranty issue.

7. Condensation Information
Cooking with Induction Cooktops
Cooking with an induction or similar cooktop, may produce condensation on the rangehood.
Unlike basic electric or gas cooking, induction cooktops heat food and liquid instantly, which in turn,
produces vapours rapidly. Because of this rapid process, the rangehood lters do not have enough
time to warm, which increases the chance of condensation forming.
There are many variables that may contribute to condensation forming, some of which include but
are not limited to:
• Variance in climate – geographical location
• Position of your home & kitchen – morning/afternoon sun
• Installation distance from cooktop to the rangehood
• Speed of food & liquid heating
• Filter size – larger canopy preferred
• Quality of pots or cookware you are using – high quality recommended
How to reduce the possibility of condensation forming:
• Ensure the rangehood is installed by a qualied professional, carefully following the installation guide
• Turn on the rangehood 5-10 minutes prior to cooking, and leave on for 10-15 minutes after cooking;
this helps clear remaining vapours from the ue.
• Start the cooking process at a low-to-medium setting and allow time for the rangehood to warm up.
• Clean lters regularly.
• Ensure constant airow in the cooking zone; this helps optimise the rate of extraction.
• Follow all induction cooktop manufacturer advice.
For further advice, tips or information regarding cooking with induction, please contact your induction
cooktop manufacturer.
