Cleaning, care, maintenance

WARNING: Before cleaning tasks, disconnect the ventilation unit from the power supply (mains fuse off). Before maintenance tasks, disconnect the ventilation unit at all poles from the power supply, secure against being accidentally switched back on and fit a visible warning sign.

CAUTION: Specialist knowledge is needed for proper cleaning and maintenance of the ventilation unit. Have your ventilation unit cleaned and serviced every two years by a specialist installer so that the ventilation unit operates absolutely hygienically.
