sible for perfect functioning of the appliance at its
installation location. He must explain the operating
principle of the appliance to the user with refe-
rence to the operating instructions. He must explain
to the user how the appliance can be isolated from
the mains whenever required.

The applicable regulations of the energy supply
companies and the regional construction regula-
tions must be observed when installing the hood.
6.2 Installation
WARNING - TO REDUCE THE RISK OF FIRE,
ELECTRIC SHOCK, OR INJURY TO PERSONS,
OBSERVE THE FOLLOWING:
The minimum distance from the worktop to the
bottom edge of the wall hood is for electrical appli-
ances 24 / 600 mm and for gas appliances 30 /
762 mm.
a.) Installation work and electrical wiring must be
done by qualified person(s) in accordance with
all applicable codes and standards, including
fire-rated construction.
The extractor hood was conceived for the exhaust
air mode. The exhaust air can be routed into a se-
parate exhaust air shaft or directly into the open
through the outside wall.
b.) Sufficient air is needed for proper combustion
end exhausting of gases through the flue
(chimney) of fuel burning equipment to prevent
back drafting. Follow the heating equipment
manufacturer’s guideline and safety standards
such as those published by the National Fire
Protection Association (NFPA), and the American
Society for Heating, Refrigeration and Air
Conditioning (ASHRAE), and the local code
authorities.
It is not allowed to pass the exhaust air into a flue
or exhaust air chimney that is in operation or into a
shaft that is linked to the heating basement. Consult
the chimney sweep responsible for your district
whenever you wish to pass the exhaust air into a
chimney that is not in operation.
During the course of planning, a chimney sweep
must be consulted if a room air-dependent hearth
is operated in the same room as the one in which a
hood is operated in the exhaust air mode. Adequate
incoming air must be ensured. The applicable con-
struction and safety regulations must be observed.
c.) When cutting or drilling into wall or ceiling, do
not damage electrical wiring and other hidden
utilities.
d.) Ducted fans must always be vented to the
outdoors.
Adequate incoming air must be ensured if a wood,
coal, gas or oil heater or an open hearth is operated
in the same room as the one in which the hood is
installed.
e.) If this unit is to be installed over a tub or shower,
it must be marked as appropriate for the appli-
cation and be connected to a GFCI (Ground
Fault Circuit Interrupter) - protected branch
circuit.
Safe operation is possible whenever the partial
vacuum in the place where the firing equipment
is installed does not exceed 4 Pa (0.04 mbar).
This can be achieved whenever the air needed for
combustion is able to enter through openings that
cannot be sealed, for example in doors, windows,
incoming/exhaust air wall boxes or by other techni-
cal means.
f.) NEVER place a switch where it can be reached
from a tub or shower.
WARNING:
To reduce the risk of fire, use only metal ductwork.

Flexible aluminium pipes, corrosion-protected
sheet metal pipes and exhaust air pipes whose
material conforms to fire B1 in accordance with
DIN 4102 can be used. Exhaust air pipes should
have a nominal diameter of 6 / 150 mm.
As standard, the blow-out opening of the extractor
hood is in the upward direction.
To pass exhaust air through the outer wall, we
recommend the use of our telescopic wall box
TM 150-045 (Ø 6 / 150 mm).
Pay particular attention to ensuring that
Note:
– the exhaust air ducts and pipes are kept as short
as possible
to prevent the ingress of water, e.g. condensate or
rain water from an uncovered exhaust air shaft, our
condensate separator RV 060-150 must be installed
in the exhaust air line. The condensate separator
must still be accessible after installation.
– the pipes are not laid at an acute angle, but as
bends and that they are inserted into the shaft at
an inclined upward angle and
– there are no cross-sectional constrictions in the
upward direction (this reduces the volume flow).
The duct units listed below are available depen-
ding on the height of the ceiling:

The dimensions above refer to a distance of 5’3” /
1.60 m from the floor to the bottom edge of the
hood.
If required, custom made duct units are available at
an extra charge.
The power connection must be placed within the
ventilation duct on the ceiling.

Installation above gas cooker / gas hob
Installation of the appliance above a gas cooking
device must conform to national safety regulations.
A minimum distance of 30 / 762 mm between the
hood and gas appliance must be observed.
Gas appliances may only be used under the
extractor hood when pots and pans are placed on
them!
Operation above gas cooker / gas hob
During operation the heat load of all hotplates and
oven must not exceed 13.5 kW.
Should the nominal heat loads of all hotplates com-
bined exceed 13.5 kW (e.g. combination with WOK
burner), during operation only a combination of hot-
plates of max. 13.5 kW must be used.
Exception:
the nominal heat loads of all hotplates combined to
a maximum of 15.4 kW can be operated for a very
short period of time (max. 15 minutes), if the hood is
running on a minimum of level 2. Otherwise there is
a risk of burns when touching the exterior of the ex-
tractor hood.

Note:
(7 7/8") 200
the extractor hood is to be installed to a kitchen
ceiling or suspended ceiling. Ensure that the
ceiling is capable of providing a firm hold for a
maximum weight of hood and accessories of 60 kg.
(13 5/8") 346
Before marking the securing holes, make sure that
no electricity wires or water pipes or other wires/
pipes are laid at the drilling points in the ceiling.
Before installation check the enclosed wall plugs
and screws are suitable for your ceiling. If neces-
sary use special wall plugs.
Installation:
1. Using the drilling template mark the position of
the screws on the ceiling.
2. Drill 4 holes Ø 8 mm for the wall plugs. Push the
plugs flush with the ceiling (Fig. 19).
Fig. 19
3. Turn two screws to a 10 mm gap. Both screws
are placed in a position, in which at a later stage
of the installation the key-holes of the suppor-
ting frame are found (namely front left and back
right from the control panel of the hood).
4. Place the hood on a suitable base. Connect the
air outlet pipe to the hood.
5. Screw the support frame to the hood with
4 screws. The marking “FRONT” must be on the
same side as the control panel (Fig. 20).

only: the enclosed extension module should be
mounted on top of the support frame. Follow the
above instructions for mounting the support
frame and hood.

6. Adjust the support frame to the desired height
and secure with 8 screws. The length of the
support frame can be adjusted in steps of
3/4 / 20 mm from 15 3/16 / 386 mm to
25 7/16 / 646 mm (Fig. 21).
Note:
ensure that the minimum distance between the
hob and the extractor hood is maintained –
24 / 600 mm for an electric hob and 30 / 762 mm
for a gas hob
7. Stainless steel ventilation ducts only
(LK 590-010/020/030):
pull the protective film off the metal surface.
8. Place both ventilation ducts over the support
frame. Take care not to scratch the sensitive
duct surface.
9. Attach the electrical plug to the support frame
with sticky tape so that it can be easily reached
later.
Fig. 21
10. Hang the hood and the support frame with the
two key-holes to the two screws in the ceiling
(Fig. 22).
Attention: the two screws cannot support
the weight of the hood. Therefore it must be
supported at this stage!

11. Adjust the hood to the final position and attach it
with all 4 screws to the ceiling (Fig. 23).
12. Connect the air outlet pipe.
13. Connect the hood to the electricity supply.
14. Pull the top duct unit up into its final position.
Secure the top duct unit with 4 screws on the
support frame (Fig. 24).
Note: avoid scratches when pulling the ele-
ments apart by placing the assembly template,
for example, over the top edge of the bottom
duct to protect it.
15. Replace the glass plates with the printed side
facing down. Position the glass plates at the
chimney side first.
Note: when putting the glass plates in place,
make sure that you do not scratch the chimney.
16. Check the appliance functions correctly.
