Guide to the Ventilation System

Functional description

The hood offers two modes of operation:

Air extraction

The air is drawn in and cleaned by the grease filters and directed outside.

The hood comes equipped with a non-return flap. This flap automatically closes when the hood is turned off so that no exchange of outside air and room air can occur. When the hood is turned on, the air pressure of the exhaust fan automatically opens the flap blowing the inside air and cooking odors outside.

Recirculation mode

Air is drawn through the grease filters and an active charcoal filter. The filtered air is then recirculated back into the kitchen through a vent at the top of the hood’s chimney.

The recirculation mode requires an install kit and charcoal filter which are optional accessories.

Before using the hood in recirculation mode, ensure that the active charcoal filter is in place, see "Cleaning and care".

Operation

Cleaning and Care

,WARNING TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:

Before cleaning or servicing the hood, disconnect it from the power supply, see "Important Safety Instructions".

The halogen bulbs are very hot

when in use. They stay hot for some time after turned off. Use caution, danger of burns. Wet cleaning the hot bulbs will cause damage. Wait a few minutes after turning them off before cleaning.

Cleaning the casing

Never use abrasive cleaners, scouring pads, steel wool or caustic (oven) cleaners on the hood. They will damage the surface.

Avoid:

cleaning agents containing soda,

–

acids or chlorides,

abrasive cleaning agents

–

e.g. powder or cream cleansers,

abrasive sponges, e.g. pot scourers or

–

sponges which have been previously used with abrasive cleaning agents.

These will damage the surface.

The following instructions for cleaning "Stainless steel" surfaces and "Stainless steel colored controls" should be followed in addition to the general "Cleaning the casing" instructions.

Special instructions for stainless steel surfaces (not applicable to the controls)

Stainless steel surfaces can be cleaned using a non-abrasive stainless steel cleaner.

To help prevent resoiling, a conditioner for stainless steel can be applied.

Special instructions for colored casings (Special order)

All external surfaces and controls can be cleaned with a mild solution of warm water and liquid dish soap applied with a soft sponge.

Do not use too much water when cleaning the controls. Water could penetrate the electronics and cause damage.

Wipe dry using a soft cloth.

It is very difficult to clean this type of surface without causing minor marks to the surface material. This can become particularly noticeable with darker colors and if there is halogen lighting in the kitchen.

Stainless steel colored controls

These controls may become dis colored or damaged if not cleaned regularly. Do not use a stainless steel cleaner on these controls.

Cleaning and Care

Grease filters

The reusable metal grease filters in the hood remove solid particles from the vented kitchen air (grease, dust, etc) and prevent soiling of the ventilation system.

The grease filters should be cleaned every3-4weeks.

A dirty filter is a fire hazard.

^ To remove the grease filter pull the

locking clips forward, lower the filter down 45°, unhook it at the rear, and take it out.

Support the grease filter so that it does not fall and damage the cooktop.

Cleaning the grease filter

By hand: use a scrub brush with a

solution of warm water and mild detergent. Do not use the pure detergent, aggressive all purpose cleaners, oven sprays, abrasive cleaning agents or limescale removers. They could destroy the filter.

In a dishwasher: place the filter

vertically in the lower basket, making sure that the spray arm is not blocked. Use a wash program with a max. temperature of 150°F (65°C). In a Miele dishwasher use the "Normal" program. Use the recommended amount of dishwasher detergent. Overuse could destroy the filter.

Depending on the detergent, cleaning the grease filter in a dishwasher may cause permanent discoloration of the filter surface. Performance of the filter will not be affected by this discoloration.

After cleaning, the filter can be placed on a towel to air dry.

While the filters are removed, clean any dirt or grease from the filter casing.

Cleaning and Care

When putting the grease filters back make sure that the locking clips are visibly facing the cooking surface

If the filters are incorrectly installed,

insert a small screwdriver into the slit along its edge to disengage it from the casing.

Active charcoal filter

In recirculation mode an active charcoal filter must be used in addition to the grease filters. It is designed to absorb cooking odors. The active charcoal filter will be replaced in the canopy above the grease filters.

Replacement active charcoal filters can be ordered from Miele.

To install or replace the charcoal

filter, the grease filters must first be removed as described in the previous section.

^ Remove the charcoal filter from the

packaging.

Slide the charcoal filter into the rear of the filter frame, then raise the front up and push it into the frame.

Replace the grease filters.

Replace the active charcoal filter at least every 6 months or when they no longer absorb odors efficiently.

Used charcoal filters may be discarded in household trash.

Cleaning and Care

Changing the light bulb

,WARNING TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:

Before changing the light bulbs, disconnect the hood from the power supply, see "Important Safety Instructions".

When in use halogen bulbs become extremely hot, use caution. Do not attempt to change the bulbs until they have had sufficient time to cool.

Do not touch the bulb surface. Fingerprints or body oils deposited on the bulb will decrease its life. Follow the bulb manufacturer’s instructions.

Remove the grease filters.

Turn the knurled screw

counterclockwise. The halogen lamp will swivel down.

Turn the bulb counterclockwise and pull it out of its socket.

Use the same bulb type as a replacement: GU/GZ10, 120V, 50W.

Replace the bulb with a new one in the reverse order.

WARNING: THIS APPLIANCE MUST BE GROUNDED

WARNING

Danger of toxic fumes.

Air extraction

Exhaust ducting and connections

Use smooth or flexible pipework made from approved non-flammable materials for exhaust ducting.

Gas cooking appliances release carbon monoxide that can be harmful or fatal if inhaled. To reduce the risk of fire and to properly exhaust air, the exhaust gases extracted by the hood should be vented outside of the building only.

Do not vent exhaust air into spaces within walls or ceilings or in attics, crawl spaces or garages.

To reduce the risk of fire, only use metal ductwork.

Please read and follow the

"IMPORTANT SAFETY INSTRUCTIONS" to reduce the risk of

personal injury. Follow all local building codes when installing the hood.

To achieve the most efficient air extraction and quietest noise levels, consider the following:

The diameter of the ductwork should

–

not be less than 6" (150 mm).

If flat ducting is used, the cross

–

section must not be smaller than the cross section of the ventilation exhaust.

– The ducting should be as short and

straight as possible.

– Use ductwork with a wide radius.

– The exhaust duct must not be bent

or compressed.

– Make sure all connections are

secure.

– Where the ductwork is horizontal, it

must slope away from the hood at

least

/8" per foot (1 cm per meter) to prevent condensation dripping into the appliance.

–

If the exhaust is ducted through an outside wall, a Telescopic Wall Vent can be used.

Air extraction

If the exhaust is ducted into an

–

inactive flue, the air must be expelled parallel to the flow direction of the flue.

Never connect an exhaust hood to an active chimney, dryer vent, flue, or room venting ductwork. Seek professional advice before connecting an exhaust hood vent to an existing, inactive chimney or vent flue.

Important

If the ductwork runs through rooms, ceilings, garages, etc. where temperature variations exist, it may need to be insulated to reduce condensation.

Condensate trap

optional accessory

In some cases, a condensate trap may also be required to collect and evaporate any condensate which may occur. This optional accessory is available for ducts 5" (125 mm) and 6" (150 mm) in diameter.

When installing a condensate trap, ensure that it is positioned vertically and if possible directly above the exhaust outlet.
