TECHNICAL DATA
IVR EC – Jet Fans
− Dispose of the fan components according to the valid rules and laws.
− A max. storage temperature of 60 °C is permitted during standstill. In case of a higher standstill temperature, the
bearings or the motor must be cooled down.
− Check unit prior to recommissioning and ensure that safety devices have been installed and they are functional.
Expiry of service life, disposal
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.
