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 flame, take particular care not to allow the oil or grease in the pan to catch fire. (Flambé)
Ducted or Recirculating?
Ducted rangehoods (or extractor range hoods) extract the cooking fumes from the kitchen and expel them from the space via ducting. Good design practice would always see a fire-rated ducting system extend to the house exterior, rather than to the ceiling cavity. When a range hood is ducted only into the ceiling space, the collection of humidity and grease can present very real health issues and fire hazards. Recirculating (or non-ducted or filtered) rangehoods extract cooking fumes and pass them through filters. As the name would suggest, they recirculate this air back into the room. Recirculating range hoods are not as effective 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 filters on a regular basis for the optimum efficiency of air filtering.
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.

  • Cleaning the Interior
    Clean the interior of the range hood 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 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.

For this appliance to function effectively, regular maintenance is a must.

  •  The function of the filter is to absorb the grease particles given off during cooking.
  •  Clogged filters and heavy oil deposits restrict airflow and may cause the motor to overheat and become a fire hazard.
  •  Filters should be cleaned every 3-6 weeks or after 40 hours of use.
  •  For induction cooktops, please aim to clean them at least every 10 days, depending on use.
  •  The filters can be washed by hand or in the dishwasher. – Washing by hand – Immerse the filter in hot water and a suitable detergent and when clean, rinse with plenty of hot water. – Dishwasher – Put the filter in the dishwasher and select a short program at low temperature. NOTE: The color of the metal mesh filters may change after several washes. This is normal and it is not necessary to change the filters.


Rangehood Size vs Cooktop Size
In addition to the size, the height of the rangehood above the cooktop is important to obtain the best performance.

Mounting Instructions
The height and position of the range hood in relation to the cooktop can greatly affect efficiency and extraction. After extensive testing, Schweigen recommends the following:
Type of Cooktop Minimum Height Optimal Height Maximum Height Electric 1200mm 1500mm 1800mm Gas 1200mm 1500mm 1800mm Heights above 1800mm will reduce the effectiveness of the air extraction rate


NOTE: We recommend using washable paint for the ceiling where the range hood is installed.

  1.  Before installing the range hood, carefully open the doors (D), then remove the filters (E). then remove (C) the fascia.
  2.  On the ceiling, mark the outline of the rangehood cut out, refer to the specifications section on p18 for dimensions.
    Note: It is always best to use the rangehood as a cutting guide, not the cabinet cut out diagram as this is only a guide.
  3.  Fit adjustable brackets (A1) to a solid structure and adjust the (A1) brackets to the correct height.
  4.  Fit the body of the rangehood (B) to the adjustable brackets (A1).
  5.  Fix fascia (C) to the body hood (B) using the screws supplied.
  6.  Fix doors (D) to the holder hinges (C) using the screws supplied.
  7. Close doors (D) to fix the holder magnets.

1. Crushed or kinked ducting creates sharp corners that create turbulence. This reduces the size and efficiency of the ducting, lowers extraction and may cause excessive noise.
2. Sweeping curves and taut ducting reduce resistance and turbulence. The airflow and extraction will be more efficient and stronger.

Back Draft Fins (For applicable models)
The supplied ducting has been manufactured with an allowance for the back draft fins 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 fix securely. Should your Back Draft Fins get stuck, this is not a warranty issue.

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 filters 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 qualified 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 flue.
  •  Start the cooking process at a low-to-medium setting and allow time for the rangehood to warm up.
  •  Clean filters regularly.
  •  Ensure constant airflow 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.


Before you contact the technical service department, make sure that the product is plugged in and power is supplied. Do not take any action that will damage the product.
