Product's operation

The hood extract fumes and steam generated during cooking from the environment, channelling them through metal filters that must be regularly removed and washed. And then, depending on the type of installation, fumes and steam:

are driven outside from the building through a drain pipe: this model does not require the use of carbon filters (ducting or external drain cooker hood - Fig. 1.);

are funneled through one or more carbon filters (usually one or two) to be purified: the clean air is then blown into the room thanks to the grid holes placed on the top of the hood's chimney (filtering or internal recirculation cooker hood - Fig. 2.).

Operating instructions

The hood must be switched on at least a couple of minutes

before starting to cook, to promote the suction of fumes and steam.

After finishing cooking, leave the hood in operation for an extra few minutes: in this case, it may be appropriate to activate the "Timer" function, which automatically switches the hood off after 10 minutes.

The page that follows shows how to use the control panel.

What speed should I use?

The unit operates at three different speeds:

speed 1: purifies the air whilst limiting electricity consumption;

speed 2: normal conditions of use (e.g. steam suction)

speed 3: for the elimination of particularly intense fumes and smells (e.g: when frying or grilling).

When should the filters be washed or replaced?

The hood has two types of filters:

metal filters: these must be removed and washed at least once a month. For the cleaning procedure refer to chapter "Cleaning" on page 11.

active carbon filter: this is only found in internal air recirculation models (Fig. 2.), and must be removed and replaced approximately every 3-4 months, depending on use.

24-hour air recycling: is turned on with the motor off by pressing "0/1" for 5 seconds, the motor turns on at the first speed for 5 minutes every 20 minutes, the altered operation has a total duration of 24H. To turn it on, press and hold key 1 for 7 seconds.

Speed 2:

normal conditions of use.

Speed 3:

extraction of particularly intense fumes and odours (e.g. frying or cooking on a hot plate)

Intense speed: starts the motor at maximum speed for 5 minutes, then automatically returns to speed 3.

Auto switch-off: to activate the auto switch-off, the hood must be switched on and then the "light control" key must be pressed for 5 seconds until all the LEDs begin to flash, by subsequently pressing one of the keys (0/1, 2, 3 ⚠) the auto switch-off time can be programmed which will differ according to the key pressed:

0/1 = 5', 2 = 10', 3 = 15', = 20' . During the auto shut-off time, it is possible to change the set speed. During the auto shut-off, the LED corresponding to the chosen time flashes

Filter timer: after 30 hours of hood operation, when the hood is switched off, all the LEDs will light up with a fixed light for 30 sec. to advise the necessary cleaning of the aluminium filters. The ⚠ key, held down for a long time with the extractor off, will reset the timer. If this key is not pressed, the same operation will come up once the hood is switched off again. This procedure will be repeated for the next 30 hours until it reaches 120 hours of operation. At the end of 120 hours, when the hood is switched off, all the LEDs will flash for the next 30 seconds to remind you to clean the aluminium filters and, if the hood is filtering, to replace the active carbon filters. Once the timer has been reset (still with the ⚠ key held down for a long time with the extractor off) the whole process will re-occur after the next 30-hours of extraction.

CLEANING AND MAINTENANCE

All ordinary maintenance operations must be carried out:

• after disconnecting the electric power supply;
• always wearing appropriate personal protective equipment (e.g.: gloves, etc...).

Failure to follow the instructions, or use of unsuitable products, may pose a risk of fire and/or damage to the equipment or other objects, for which the Manufacturer cannot be held responsible.

- When cleaning any of the components or accessories, NEVER use:

• abrasive or powder detergents;
• aggressive or corrosive detergents (e.g. hydrochloric/muriatic or sulphuric acid).
- abrasive or sharp tools (e.g. abrasive sponges, scrapers, steel brushes, etc.);
- water sprays

STAINLESS STEEL AND OTHER METAL SURFACES

The INSIDE and the OUTSIDE of the hood should be cleaned solely by using a damp cloth with little neutral soap. It is also possible to use a steel specific cleanser, paying attention to the instructions written on the canister or bottle.

To conclude the cleaning operation, rinse using a clean wet sponge or cloth and then use a rag to dry the surface (in case of satin steel, please rub according to the finish pattern).

CONTROL PANEL

Please follow the instructions stated above for metal surfaces.

GREASE METAL FILTERS

These filters are usually made in aluminium or stainless steel, and their main purpose is to block the particles of oil and fat suspended in the cooking fumes.

An excessive accumulation of grease inside the filters could cause unpleasant smells and decrease the suction power of the hood. Please note that accumulated fat is highly flammable: any fire could lead to severe damage to both users and the product.

For these reasons, the anti-grease filters should be washed at least once a month, immersing them into hot water and dish soap for at least one hour.

Rinse with plenty of water and wait for the filters to be fully dry before putting them back in place.

Please note that the maximum temperature is 70^ C/158°F; higher temperature can cause darkening in the metal (please note that this DOES NOT impair the operation of the filter).

For their removal see Fig. 5.

ACTIVE CARBON FILTERS

These filters cannot be washed or regenerated, and should therefore be replaced every 3 to 4 months, depending on the hood usage. Damp environments, high temperature, soiled anti-grease filters and the use of an induction hob could result into an accelerated decay of the filters.

There are two different kind of carbon filters:

- a rectangular one (similar to the metallic anti-grease filter, it can be removed by simply pulling the handle);

- a rounded one (usually secured to the blower, it can be removed by counter-clockwise twisting).

For the instructions on carbon and anti-grease filters removal, see Fig. 6.

Internal recirculation hoods have to be used only with active carbon filters installed.

FUME EXHAUST CONNECTION

DUCTING/SUCTION VERSION

This type of hood is equipped with a top air outlet for discharge

of fumes outside the house, which has to be connected with the inlet of the building chimney, commonly through a hose (not provided).

Horizontal tube sections must be slightly tilted upwards, to help channelling of the air to the outside. Fume discharge tubes crossing particularly cold environments (e.g. attics) should be insulated, to prevent condensation caused by temperature differences.

Suction type hoods DO NOT require carbon filters, which, on the contrary, can limit their performance.

Any changes to the tube, sudden diameter reductions, and bends, may prevent the hood from reaching optimum suction capabilities, and may jeopardise the operation of the motor, relieving the Manufacturer from all responsibility.

Make sure that the flue is in perfect working order, and that a square (concrete) or round (metal) static wind break ventilation tower with useful output section not less than double the diameter of the flue (UNI 7129) is installed at the top of the flue itself.

Comply with all air discharge regulations.

The drain chimney of the building should be dedicated to the hood only, so under no circumstances it should be shared with other devices, such as bathroom extractors, air-conditioning units, fireplaces, wood or gas stoves.

FILTERING/AIR RECYCLE VERSION

In order to prevent both the flow of unclean air in the room and any damage to the fan blower, once saturated, the carbon filters should be

promptly replaced. Once the carbon filters are saturated, they should be replaced as soon as possible, to prevent both the flow of unclean air and damages to the blower fan.
