Standstill and disposal

m
Danger to life due to electric shock!
When dismantling, live parts can be exposed, which can result in electric shock if touched .
Before dismantling, isolate the fan 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
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 result in danger
to persons, the environment as well as machines and systems. The corresponding operator guidelines applicable on-
site must be observed and used.
