In general, the ventilation hood should extend at least 3” on both sides of the cooking area for optimal performance.

Exhaust-Air Mode: The ventilator fan draws the vapors produced during cooking into the extractor hood, where they pass through the grease filter and out into the open air. The grease filter absorbs the grease contained in the vapors produced during cooking. The kitchen is kept virtually free from grease and odors.

Recirculating-Air Mode: To operate in this mode, it is necessary to install an Activated Carbon Filter. The ventilator fan draws the vapors produced during cooking into the extractor hood, where they pass through the grease filter before the clean air is discharged back into the kitchen. The grease filter absorbs the grease while the activated carbon filter absorbs any odorous substances.

Wipe away grease stains, change carbon filters (for recirculating units only), and wash grease filters on a timely basis. View our How-to-Videos to learn how to clean stainless steel.

Warning: Do not use the ventilation system without the filters in place or with grease-laden filters or surfaces. To avoid risk of fire and explosion, do not use flammable liquids or solvents. Always unplug or disconnect the appliance from the power supply before servicing. Always be sure the entire hood (including filters and light bulbs) has cooled and grease has solidified before attempting to clean any part of the appliance.

The efficiency of the ventilator depends on the cleanliness of the intake and filters. Cleaning frequency depends on the amount and type of cooking.

To clean metal grease filters: Remove the filters according to the instructions in the Use & Care Guide. Drain and wipe all excess grease with a dry paper towel. Soak the filters in hot water and detergent and gently brush or agitate in the water to loosen food particles. Do not use products containing ammonia, abrasives or oven cleaners. Rinse the filters and let them dry before placing in the ventilator. Filters may also be cleaned in an automatic dishwasher (please do not include any other items or cutlery in the wash). We recommend grease filters be cleaned every 1-3 months depending on usage.

To clean activated carbon/charcoal filters (applicable to certain models that utilize activated carbon/charcoal filters): Activated carbon/charcoal filters cannot be cleaned or washed – they must be replaced. Activated Carbon Filters are used to neutralize odors when your hood is recirculating air around the kitchen. Carbon filters should be replaced when they are noticeably dirty or discolored (usually every 6 to 12 months, depending on ventilator usage). They may be purchased from your dealer.

To clean stainless steel: Wipe with the grain when cleaning stainless steel. Use a mild, non-abrasive cleaning agent or stainless steel cleaner with a soft cloth. Wipe dry to avoid water marks. Warning: Some stainless steel cleaners are known to have negative effects on materials other than stainless steel. Make sure to apply stainless steel cleaner to stainless steel components only!

To clean painted surfaces: Wash with hot soapy water, rinse and then dry. Do not use powder cleaning agents, steel wool pads, oven cleaners and other abrasive cleaning materials.

To clean anodized aluminum surfaces: Wash with hot, sudsy water, then rinse and dry. Mild detergents and cleaning agents are acceptable. Do not use powdered cleansers, abrasive cleaners, scrubbers, or steel wool pads.

To clean plastic surfaces: Wipe with a damp, soapy sponge or cloth, then rinse and dry. Do not remove any control knobs.

In general, it should be placed 30” above the cooking area. Contact a professional installer for additional information related to your specific situation.

CFM: The amount of air flow moved by the ventilator is measured by CFM. CFM stands for cubic feet per minute. The higher the CFM, the higher the air flow.

Sones: A sone measures the amount of sound that is perceived by a person. It is not the same thing as a decibel, which measures the intensity of sound. One sone is equivalent to the sound of a quiet refrigerator. The lower the sone, the lower the sound perceived.

Metal Grease Filter: The grease filter should be cleaned every 1-3 months depending on usage. When you remove your filter you may notice it is discolored, this is normal and nothing to worry about. Directions for cleaning the grease filter are listed below:

1. Remove the filters according to the instructions in the Use & Care Guide.
2. Drain and wipe all excess grease with a dry paper towel.
3. Soak the filters in hot water and detergent and gently agitate in the water to loosen food particles. Do not use products containing ammonia, abrasives or oven cleaners. Rinse the filters and let them dry before placing in the ventilator.
4. Filters may also be cleaned in a dishwasher (please do not include any other items or cutlery in the wash).
