– The appliance must only be connected by an
authorised specialist, paying attention to
the relevant regulations of the power supply
companies and the regional construction
regulations.
Also observe the assembly instructions!
– Connecting cables must not come into contact
with hot cooking surfaces.
– Do not operate the extractor hood without
inserted lamps.
– Never operate the appliance without a grease
filter.
– Hazardous or explosive substances and vapours
must not be extracted!
– The user is responsible for expert use and the
perfect condition of the appliance.
– Only ever operate the appliance under
supervision.
– Caution! Over-greased filters are a fire risk!
Only ever deep-fry under the extractor under
constant supervision. Pay attention to cleaning
the grease filter on a regular basis.
– Fire risk! Do not flambé meals under the
extractor hood!
– Operation of the extractor hood above a hearth
for solid fuels (coal or wood etc.) is only permitted following certain guidelines.
– Gas appliances may only be used under the
extractor hood when pots and pans are placed
on them!
– When using more than 3 gas-operated rings at
the same time, please operate the extractor
hood at level 2 or higher. This prevents a
build-up of heat in the appliance.
– For safety reasons, do not place any heavy
objects on the top of the appliance.
– Do not clean the appliance with a steam
cleaning apparatus or with water pressure
because this poses a risk of short-circuits.
– Isolate the appliance from the mains during
every maintenance operation. To do this, remove
the mains plug or actuate the corresponding
fuse.
If the mains plug is not accessible, the appliance
must be disconnected from the power mains by
means of the domestic installation fuse.
– Repairs must be carried out by authorised
specialists, thus ensuring electrical safety.
– No warranty claims can be lodged in the event
of damage caused by failure to observe these
instructions.
– 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.
– 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
other technical means.
– If the appliance is to be operated only with the
window open (to ensure adequate incoming air),
you can use the window switch.
A switch (normally open) is fitted on the window.
On the appliance, this switch is connected to the
window switch terminal on the main electronics.
The appliance can now only be operated when
the window is open.
Important: the window switch must only be
connected by an authorised specialist.
Note: the light function works without restriction.
– After a power failure, the extactor will not go on
again automatically. You can recommence operation by turning a knob or by pressing any key.
Technical modifications reserved.

started to flash.
The stainless steel grease filters can be removed
easily for cleaning (see Fig. 13):
Disconnect the power supply (switch off the fuse).
Grip the grease filter handle and push the slide
towards the rear. Then pull the grease filter downwards out of the holder; repeat the operation for the
other grease filters.
You can clean the stainless steel grease filters in a
dishwasher at a maximum temperature of 65°C,
where it should be supported vertically
to allow
food or rinsing residues to drain off.
If possible, the inner parts of the housing should be
wiped out in hot rinsing water when replacing the
filters.
Caution:
when cleaning the inside of the housing, beware of
protruding parts.
After having cleaned them, re-insert the grease
filters in the extractor hood in reverse order.
Note:
the handles of the grease filters must be visible
after assembly.
Press the F key to set the elapsed hours counter to
zero. Flashing of the indicating lamp goes off.

Fig. 13
Fig. 14
Cleaning the extractor hood
Clean the extractor hood and the aluminium-
design ventilation ducts (LK 590-011/021/031)
with a soft cloth and mild detergent solution only.
Clean the stainless-steel design ventilation
ducts (LK 590-010/020/030) with mild detergent
solution and apply stainless steel care agent to the
metal surface using a soft cloth.
Cleaning the glass plates
Apply commercially available window cleaning
agent with a soft, moist cloth.
To facilitate cleaning, you can detach the glass
plates as follows:
Detach the grease filters. In the extractor hood, you
will find two openings on the upper side through
which you can lift the glass plates singly with a
blunt object (e.g. handle of a wooden spoon) to
detach them with greater ease. The remaining
glass plates can then be lifted from above.
If they are extremely soiled, the glass plates can be
cleaned in a dishwasher at a maximum temperature
of 55 °C.
Note: when putting the glass plates back in place,
make sure that you do not scratch the chimney.
Replace the glass plates with the printed side
facing down. Position the glass plates at the chimney side first.
Cleaning the aluminium panel
Clean the control panel with a sponge and mild de-
tergent solution only. Dry with a soft, dry cloth. Do
not use any strong or caustic cleaning agents or
brushes and abrasive cleaner to clean it. Do not use
strongly alkaline cleaning agents (such as oven
spray) because these are aggressive to the
aluminium surface. Do not use any abrasive
sponges either.

6.1 Technical data
Weight without support frame and LK:
AH 590: 35 kg
AH 592: 33 kg
Weight with support frame and LK:
max. 60kg
Dimensions: 1198 x 700 mm
Electrical connection
Pay attention to the rating plate data.
The mains connecting cable must at least
correspond to the type H 05 VV-F G 0,75.
The appliance must only be connected by an
authorised specialist. The specialist is responsible for perfect functioning of the appliance at its
installation location. He must explain the operating
principle of the appliance to the user with reference
to the operating instructions. He must explain to the
user how the appliance can be disconnected from
the mains whenever required.
Connection possibilities
The plug of the connecting cable is inserted into
the socket on the ceiling. If this is not possible, the
disconnection of all the poles of the appliance from
the mains must be achieved by way of the domestic
fuse, or by using an accessible disconnecting device
with a contact gap of at least 3 mm.
6.2 Installation
The applicable regulations of the energy supply
companies and the regional construction regula-
tions must be observed when installing the hood.
The minimum distance from the worktop to the
bottom edge of the hood is for electrical appliances
600 mm and for gas appliances 700 mm.
The extractor hood was conceived for the exhaust
air mode. The exhaust air can be routed into a separate exhaust air shaft or directly into the open
through the outside wall.
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 construction and safety regulations must be observed.
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.
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 technical means.
6. Assembly instructions
13
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 150 mm.
Pay particular attention to ensuring that
– the exhaust air ducts and pipes are kept as short
as possible
– 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).
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 150).
Note:
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 duct units listed below are available depending on the height of the ceiling:
Stainless steel-design ventilation duct:
LK 590-010 for ceiling heights of 2.39 - 2.64 m
LK 590-020 for ceiling heights of 2.64 - 2.89 m
LK 590-030 for ceiling heights of 2.89 - 3.14 m
Aluminium-design ventilation duct:
LK 590-011 for ceiling heights of 2.39 - 2.64 m
LK 590-021 for ceiling heights of 2.64 - 2.89 m
LK 590-031 for ceiling heights of 2.89 - 3.14 m
The dimensions above refer to a distance of 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.

Installation above gas cooker / gas hob
Installation of the appliance above a gas cooking
device must conform to national safety regulations
(e.g. in UK CORGI standards).
A minimum distance of 700 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 combined exceed 13.5 kW (e.g. combination with WOK
burner), during operation only a combination of hotplates 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 extractor hood.
The following note applies to extractor hood
AH 592-120 only; this model does not have an
integrated fan:
The extractor hood can only be used in exhaust air
mode. The exhaust air is conveyed upwards through
an externally attached fan via a ventilation shaft or
directly into the open air through the outer wall.
The extraction function is realised by an external
fan module. We recommend the fan modules
GB 032-107 or GB 052/053-140 from our Gaggenau
range; the extractor's electronic circuitry is
optimised for these fan modules.
For the electrical connection between the extractor
hood and external fan see installation instructions
for the external fan.
For safety reasons, if the connecting cable to
the external fan has been damaged, it must be
replaced by the manufacturer or the after sales
service or similarly qualified persons.
