• Do not place the appliance near a heat source. Do not subject the power
cord to direct heat (such as a heated hotplate, open flames, hot iron sole
plates or heaters for example). Protect power cords from oil.
• See to it that the appliance is properly positioned to ensure a high stabil-
ity during its operation and make sure that no one can trip over the power
cord.
• The appliance is not splash-proof.
• For indoor use only.
• Do not store the appliance outdoors.
• Store the appliance in a dry place inaccessible to children (pack the ap-
pliance).
• If the power cord is damaged, it must be replaced by the manufacturer
or a repair shop authorized by the manufacturer or by similarly qualified
persons in order to avoid a hazard.
• Unplug the appliance before filling and cleaning.
Setting up / operation
1. Place Oskar big on a flat surface in the desired area. Plug the mains cable
(3) into a electric socket. Use the filling opening (11) to fill the lower part
(2) with water up to the maximum mark (14), either at a water tap or with
a watering can. When you have filled the lower part at the tap, carefully
fit the upper part (1) to the lower part (2).
2. Start the appliance by pressing the on/off switch (5). The blue LED should
then light up. If a red pilot lamp (10 and 14) lights up however, this indi-
cates either lack of water in the appliance or failure to seat the upper part
correctly on the lower part. If there is no water in the appliance, the motor
will stop automatically.
3. By pressing the speed level selector button (6) you can change the humid-
ity output (1 to 4 LEDs = normal evaporation to high evaporation).
4. You can use the hygrostat to set the desired air humidity. To do this, press
on the hygrostat button (7). You can choose between the following lev-
els: 40 % relative air humidity (1 blue LED), 45 % (2 blue LED), 50 % (3
blue LED), 55 % (4 blue LED), constant operation (5 blue LED). If the lamps
are flashing, this indicates that the desired air humidity has already been
reached. Please note that the hygrostat needs about 3 second to measure
the current humidity in the room. The hygrostat switches on automatically
once the relative air humidity in the room sinks below the preset value.
We recommend that you set your room humidity to 45 % (comfort range).
5. If you find the lamps too bright (in a bedroom for example), you may reduce
the light intensity by pressing the night mode key (8). You can choose
between three different modes:
• Normal mode (default mode)
• Dimmed mode (push once)
• Lights-out mode (push twice)
By pushing the dimmer button once more, you can go back into normal
mode.
If there is no water in the appliance, the red LEDs (10 and 14) light up in all
modes (normal and night mode). The red light can not be dimmed.
6. Oskar big has a reminder function for filter change. At first use timer will
be set automatically. After a whole operating duration of two months the
filters need to be changed. In this case, the blue LED above the reset
