1.11 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 unit from the mains power supply and
protect against being switching on again!
Parts and components of the unit, 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 auxi-
liary 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.
