Operation with mains power
The ventilator switches to operation with mains power when
connected to the mains power supply. The integrated battery is
recharged during mains power operation. The external battery
is recharged once the integrated battery is fully charged.
The LED next to the plug symbol s lights up yellow.
If the mains power supply fails, the ventilator automatically
switches over to the external battery.
If an external battery is not available in the event of a power failure,
the ventilator switches over to the integrated battery and
continues operation for at least 10 minutes (provided that the
integrated battery was fully charged).
● The mains power supply must be restored without delay.
To ensure that the battery is always fully charged:
● Connect the ventilator to the mains power supply and
switch it on.
The ventilator may only remain connected to the mains
supply in well ventilated rooms.
Oxyhydrogen gas is generated when charging batteries
and may explode when a sufficient concentration has
accumulated.
● Leave the ventilator in standby mode or start ventilation.
