IMPORTANT SAFETY INSTRUCTIONS
Installation
, WARNING
To reduce the risk of fire only
use metal ductwork.
When installing the hood, follow the
recommended minimum safety
distances between a Miele cooktop and
the hood:
22" (55 cm) above electric cooktops,
–
26" (65 cm) above gas cooktops,
–
26" (65 cm) above an open grill.
–
If local building codes require a greater
safety distance, follow their
requirement.
For non-Miele cooking appliances
maintain the safety distances
recommended by the appliance
manufacturer in their instructions.
If there is more than one appliance
beneath the hood and they have
different minimum safety distances
always select the greater distance.
Be careful not to damage hidden
electrical wiring or plumbing when
cutting or drilling into the wall or ceiling.
Any fittings, sealant, or materials
used to install the ductwork must
be made of approved non-flammable
materials.
Never connect an exhaust hood to
an active chimney, dryer vent, vent
flue, or room ventilating ductwork. Seek
professional advice before connecting
an exhaust hood vent to an existing,
inactive chimney or vent flue.
Ducted fans must always be
vented outdoors.
Make sure that the airflow in the
room is sufficient for combustion
and exhausting of all non-electric
heating appliances (water heaters, gas
cooktops, gas ovens, etc.), otherwise
backdrafts may occur. Follow the
heating manufacturer’s guidelines and
safety standards or those published by
the National Fire Protection Association
(NFPA), or the American Society for
Heating, Refrigeration and Air
Conditioning Engineers (ASHRAE).
If in doubt, consult an experienced
professional.
Do not use an extension cord to
connect the appliance to electricity.
Extension cords do not guarantee the
required safety of the appliance, (e.g.
danger of overheating).

The ventilation hood works by 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.

cleaner.
To help prevent resoiling, a conditioner
for stainless steel can also be used.
Apply sparingly with even pressure.
Stainless steel colored controls
These controls may become
discolored or damaged if not
cleaned regularly.
Do not use a stainless steel cleaner
on these controls.
^
Glass surfaces can be cleaned using
glass cleaner.
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.
14
Cleaning and Care
Grease filters
The reusable metal grease filters
remove solid particles from the vented
kitchen air (grease, dust, etc).
The grease filters should be cleaned
every 3 - 4 weeks or whenever the
grease filter indicator lights.
A dirty filter is a fire hazard.
^ To remove the grease filters press the
locking clips in towards the middle of
the filter. Holding carefully, lower and
remove the filter.
Clean the filters
^
- by hand: use a scrub brush in
warm water with a mild detergent.
- in a dishwasher: place the filters
vertically in the lower basket, making
sure that the spray arm is not
blocked.
Depending on the detergent,
cleaning the grease filters 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 filters can be
placed on a towel to air dry.
^ While the filters are removed, clean
any dirt or grease from the filter
casing to prevent the risk of fire.
When putting the grease filters back
make sure that the locking clips are
visible facing down towards 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.
^
After returning the grease filters,
press the grease filter button for 3
seconds to reset the timer. The
indicator light will go out.
^
If the grease filters are cleaned
before the grease filter timer has
reached its maximum, the grease
filter button should be pressed for
6 seconds to reset the counter to
zero.

Cleaning and Care
Changing the light bulbs
Before changing the light bulbs,
disconnect the hood from the power
supply by either removing the fuse,
unplugging it, or manually "tripping"
the circuit breaker.
When in use halogen bulbs become
extremely hot, and they can burn
your hands. Do not attempt to
change the bulbs until they have
had sufficient time to cool down.
Do not touch the bulb surface.
Fingerprints or body oils deposited
on the bulb will decrease the life of
the bulb. Please follow the bulb
manufacturer’s instructions.

Appliance dimensions and Installation
Do not install this hood over any
appliance that burns solid fuel stove.
The minimum safety distance
allowed between the top of a Miele
cooking surface and the bottom of
the hood S is:
- 22" (55 cm) above electric cooktops
- 26" (65 cm) above gas cooktops
- 26" (65 cm) above an open grill
For non-Miele cooking appliances
maintain the safety distances
recommended by the cooktop
manufacturer in their installation and
operating instructions.
If there is more than one appliance
beneath the hood and they have
different minimum safety distances
always select the greater distance.
Cut out area in wall or ceiling for
entrance of 6" (150 mm)
ductwork or 5" (125 mm)
ductwork with a reducing collar.
See "Warning and Safety
instructions" for further information.
26" (65 cm) is recommended for all

WARNING
,
Danger of toxic fumes.
Air extraction
Exhaust ducting and connections
The ducting should be as short and
–
straight as possible, and the number
of sharp bends should be minimized.
Gas cooking appliances release
carbon monoxide that can be
harmful or fatal if inhaled.
The exhaust gases extracted by
the hood should be vented
outside of the building only
Do not terminate the exhaust
ducts in attics, garages,
crawlspaces, etc.
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.
.
For most efficient air extraction, the
–
diameter of the ductwork should not
be less than 6" (150 mm). Use of flat
ducts also reduces the air extraction
efficiency.
Noise levels of the hood will increase
–
if flat ducts or round ducts of less
than 6" (150 mm) in diameter are
used.
– Use smooth or flexible pipes made
from approved non-flammable
materials for exhaust ducting.
– Where the ductwork is horizontal, it
must slope away from the hood at
1
least
/8" per foot (1cm per meter) to
prevent condensation dripping into
the appliance.
– If the exhaust is ducted through an
outside wall, a Miele Telescopic Wall
Vent can be used.
27
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, vent
flue, or room venting ductwork. Seek
professional advice before
connecting an exhaust hood vent to
an existing, inactive chimney or vent
flue.
Condensate trap
Important:
If the ductwork runs through rooms,
ceilings, garages, etc. where
temperature variations exist, it may
need to be insulated to reduce
condensation. In some cases, a
condensate trap may also be required
to collect and evaporate any
condensate which may occur.
When installing a condensate trap,
ensure that it is positioned vertically
and if possible directly above the
exhaust outlet.
