OPERATING INSTRUCTIONS
Before first use
Prior to the start of use of a new unit, wipe it with a wet and then a dry cloth.
Airing mode
In this mode the vapors are ventilated through the output pipe into the shaft and out of the room. If there are
carbon filters installed in the unit, remove them (see the Cleaning and Maintenance paragraph).
1. Select the required fan power level by pressing the „+“ and „-“ symbols (1 – 3).
2. After use, switch the unit off by setting the fan power level to „0“.
Re-circulation mode
If you have no possibility to ventilate the air out of the room, the re-circulation mode can be selected. In this mode
the vapors are filtered through metal and carbon filters. Active carbon in these filters absorbs smells, and the clean
air flows back to the room through holes in the upper chimney cover. For this mode, it is necessary to buy and
assemble the corresponding carbon filters (see the Cleaning and Maintenance paragraph).
1. Select the required fan power level by pressing the „+“ and „-“ symbols (1 – 3).
2. After use, switch the unit off by setting the fan power level to „0“.
Switching the lighting on and off
Press the button to turn on the light. Switch the light off by repeatedly pressing the button.
The lighting direction can be adjusted by tilting the lights.
Delayed OFF function
1. Select the required fan power level (1 – 3).
2. Press the button to activate the delayed off function. A dot symbol will blink on the display.
3. Set the required delayed off time by repeatedly pressing the „-“ and „+“ symbols in the range of 10 – 90 minutes.
Tens of minutes will be displayed, i.e. 1 = 10 minutes, 2 = 20 minutes etc. Confirm by pressing the button (the
fan power level will be displayed, and the dot symbol will blink).
Note
: If you don‘t confirm the delayed off settings within 20 seconds, the settings will be erased, and the
delayed off function will be deactivated.
4. The unit will switch off automatically after the preset time runs out.
Note:
If you press the button during the countdown, or switch off the fan manually before the time runs out,
the delayed off function will be deactivated.
