IV Operating conditions
1. The kitchen hood was designed for removal of kitchen fumes to the outside. It
should be connected to an appropriate ventilation duct (do not connect the hood to any
chimney, smoke or flue-gas ducts which are in use).
2. The device shall be installed at the distance of at least 450 mm above the working
top of an cooker.
3. Do not leave open flame under the hood. When removing pots from the burners set
the flame to its minimum level.
4. Any food cooked in fat shall be constantly monitored, since overheated fat can ignite
very easily.
5. The grease filter of your kitchen hood should be cleaned at least every 2 months,
because a filter soaked with grease becomes easily flammable.
6. Pull the plug of the power cord from a wall socket before any cleaning, filter
replacement or repair operation.
7. If any other non-electric devices are used in the same room as the hood (e.g. liquid
fuel ovens, flow-through or volumetric water heaters), it is necessary to provide
appropriate ventilation (air supply). Safe operation is possible when during
simultaneous operation of the hood and combustion devices dependent on air supply
the negative pressure of not more than 0.004 milibar is maintained at the location of
these devices inside the room (this point does not apply when the hood is used as an
odour absorber).
8. When connecting to 230V power supply network use an electric socket in working
order.

i) Fix lower chimney module to the hood body (fig.4). Use suitable bolts.
3. Connecting to the power network and operation check
After connecting the device to the power supply network (in accordance with the
requirements defined above) it is necessary to check the lighting of the hood and
whether its motor works correctly. The wall socket shall be accessible for
disconnecting the plug after the hood is installed.
Important!
If the fixed power supply cable is damaged, it should be replaced at the manufacturer or
at an authorized servicing outlet, or by a qualified person to avoid danger.
4. Setting the operation mode of the kitchen extractor hood
4.1 Setting the air extractor mode of operation of the hood
In the extractor mode air is discharged to the outside by a special conduit. In that
setting any carbon filters shall be removed.
The hood can be connected to the opening discharging air to the outside by
means of a rigid or flexible conduit of 150 or 120 mm diameter, and appropriate clamps
for conduits which should be purchased in a shop selling installation materials.
A qualified installer should be commissioned to make the connection.

4.2 Fan speeds
The lowest and medium speeds should be used under normal conditions and with
low concentration of fumes. The top speed should be used in case of high concentration
of kitchen fumes, e.g. during frying or grilling.
1. Operational safety
All safety instructions included in this manual shall be observed without exception!
Grease filters should be cleaned and replaced according to manufacturer’s instructions,
or more frequently in periods of intensive use (more than 4 hours a day).
If a gas cooker is used it is forbidden to leave uncovered flame. When removing pots
from gas burners set the flame to its minimum level.
Always make sure that flame does not extend outside the pot. Such a situation causes
undesired energy losses and dangerous heat build-ups.
The hood should not be used for other purposes than those for which it was designed.
2. Operation
2.1 Control panel
-The pushbuttons "-" and "+" -- serve the purpose of selection of the fan speed in a
speed area from 1 to 4.
-Push the pushbutton "+" briefly to increase the fan speed; holding it pushed down for
about 2 seconds when the motor is not working causes the bringing in the automatic
system operation and the letter "A" is shown (switch on before cooking).
- Push the pushbutton "-" briefly to reduce the fan speed; holding it pushed down for
about 2 seconds causes the switching off the extraction hood motor from each of its
settings.
-The pushbutton "T" (timer) serves the purpose:
-of the programming the time of the fan switching off
-of deleting the flashing letter "F" or "C"
-of highlighting pushbuttons.

- The lighting pushbutton "L" is used to switch on and off the extraction hood lighting;
independently of the motor work status, push this pushbutton to switch on/off the
lighting; holding it pushed down for about 2 seconds causes the lighting switchover
from the maximum level to the nearest lower level.
2.2. Program function
ODOUR SENSOR:
The automatic system operation is activated before the beginning of cooking and after
5 minutes of the moment of the first connection of the plug to the 230 V ~ power
network (calibration of the air sensor for the surrounding conditions). The switching-on
the automatic operation mode puts the process of air examining by means of the odour
sensor into operation. The appearance of a pollution on a determined level has the
switching-on of the extraction hood with the speed adequate to this pollution level as
the consequence. The reduction of the pollution level causes a gradual reduction of the
extraction hood power up to the switching off. The reduction of the extraction hood
power is carried out every 1 minute. The not reduction of the pollution level extends
the working time of the extraction hood at the same power by another minute. The
appearance of the pollution on the higher level causes an immediate rise of the
extraction hood power. The discovery of the maximum pollution level puts the
extraction hood into operation for one minute on the speed 4 and if after this time the
pollution level is reduced, the fan starts to work for a minute on the speed 3. A further
decline in the air pollution causes the reduction of the motor speed up to the switching
off.
-Switching-on of the automatic work (of the odour sensor): Hold pushbutton "+"
pushed approximately 2 seconds (A appears). Exit from the automatic mode: keep
the pushbutton "+" pushed approximately 2 seconds (0 appears).
- Timer: There is a possibility of pre-programming the automatic switching off of the
extraction hood fan in a moment chosen at own discretion in the area of 10 to 90
minutes in 10 minute steps.
-To activate the function of the programming switch on the extraction hood motor
with the pushbutton+ on the desired speed and then push the pushbutton T. A
flashing number appears on the display device to inform us that the control unit has
entered into the time programming mode.
IO 00236

-Choose the time of the automatic motor switching off by means of the pushbutton
"+", taking into account that the number shown by the display device and multiplied
by the 10 minute interval corresponds to the time of the delayed switching off the
extraction hood motor (e.g. the number 1 = 10 min, the number 2 = 20 min, the
number 3 = 30 min and so on).
- After the value of the delayed switching off has been selected, confirm it with the
pushbutton T again, the display device stops flashing and shows the speed chosen
earlier and the flashing point near the speed number signals the down-count of the
time for the switching off of the extraction hood motor. The deactivation of the
function of the automatic switching off of the extraction hood motor can be made by
pushing the pushbutton T once more in the course of the time down-count.
-Signalling of the aluminium filter cleaning - displaying of the letter F or C 100 h
Function mentioned above do not collide with the work of the extraction hood, the
number of the speed (from 0 to 4) is, however, not visibly until the moment of
deleting the shown letter C or F. Press T for about 10 seconds to delete them after the
replacing or cleaning of the filter.
-Push the pushbutton T (timer) for about 2 seconds to turn on or off the highlighting
of pushbuttons.
Remark: The activation of the function of the automatic switching off (timer) must be
carried out within 20 seconds, since otherwise, if no activity has been executed, the
extraction hood changes into the normal work mode automatically.
The electronic system is protected with a fast-acting 250 V - 2 A cut-out (glass
fuse insert 5 x20). During the short-term mains voltage drop a clearing or a fall of
the microprocessor system can appear and the latter do not react to the
commands entered from the keyboard any more. Disconnect the extraction hood
from the supply network and then switch it on again in order to reset the system.
