End of life and disposal

WARNING
When dismantling, live parts can be exposed, which can result in electric shock if touched. Before
dismantling, 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 and/or other effects that cannot be directly discerned, must be disposed of expertly and properly after
disassembly 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. impellers, rolling bearings, filters, etc. can be a hazard to people, environment as well as
machines and systems.
