Additional Details and Usage

The hood features perimeter extraction panels, which are described as very efficient and aiding noise reduction. Filters are provided to help remove grease from the steam produced during cooking. Built-in lights are included to illuminate the cooking area or add to the ambience of the kitchen.

The 24 h function, when selected, refreshes the air for approximately 10 minutes every hour over a 24 hour period at minimum speed and an imperceptible noise level. A special time-setting option allows the hood to run after the end of cooking for a pre-set time and then switch off automatically. An intensive or turbo setting is available when extra fast extraction is required.

A warning light advises when the filters need changing. Connection between hob and hood is indicated, in conjunction with Auto-Vent 2.0 (further operational details are not stated in source).

Accessories Included

Remote control.

Frequently Asked Questions

Can this ceiling hood be used in recirculation mode?

Yes. The extraction type is specified as ducted out or re-circulation possible. Compatible charcoal filters such as KITALLFC and KITFCKLTR are available for use in re-circulation configurations.

What is the minimum installation distance from the hob?

The minimum distance from a gas hob is 650 mm, and the minimum distance from an electric hob is also 650 mm.

How loud is the SMEG KLT9L4X at different speeds?

At minimum speed the airborne acoustical A-weighted sound power is 48 dBA. At maximum standard speed it is 63 dBA, and at boost or intensive speed it is 69 dBA. Extraction rate data also specifies 48 dBA at speed 1, 55 dBA at speed 2, 62 dBA at speed 3 and 69 dBA at intensive speed.

What energy efficiency rating does this hood have?

The hood has an energy efficiency class B, with annual efficiency consumption (AEChood) of 94 kWh/year. Fluid Dynamic Efficiency class is B and Lighting Efficiency class is also B.

How are the filters maintained and when should they be changed?

The hood uses three aluminium anti-grease filters to help remove grease from steam during cooking. A filter replacement indicator with warning light advises when filters need changing. Compatible charcoal filters such as KITALLFC and KITFCKLTR can be washed in a dishwasher and dried in an oven following the specified temperature and time instructions.

What special functions does the 24 h setting provide?

When the 24 h function is selected, the hood refreshes the air for about 10 minutes every hour over a 24 hour period at minimum speed and an imperceptible noise level. This is in addition to the standard speeds and intensive or turbo setting.
