ling, isolate the unit from the mains power supply and protect against being switching on again!
Parts and components of the fan, whose service life has expired, e.g. due to wear and tear, corrosion, mechanical load,
fatigue and/or other effects that cannot be directly discerned, must be disposed of expertly and properly after disassem-
bly in accordance with the national and international laws and regulations. The same also applies to auxiliary materials
in use. Such as oils and greases or other substances. The intended and unintended further use of worn parts, e.g.
