Safety information
Warning: Danger from falling fan or fan parts.
♦ Check the surface before installation for load bearing capacity.
♦ Consider all static and dynamic loads when selecting hoisting equipment and fastening components.
General safety information
♦ Installation may only be carried out by adequately qualified persons, details see Table 1 Qualifications, page 3.
♦ Abide by the system-related conditions and requirements of the system manufacturer or plant constructor.
♦ Do not dismantle or circumvent safety elements, or put them out of function.
♦ Move the rotor of the fan by hand before you install it in order to check that it moves freely.
♦ Provide contact and intake protection and ensure safety distances according to DIN EN ISO13857 and DIN 24167-1.
♦ Prevent the possibility of foreign bodies being drawn in.
♦ To reduce transmission of vibration to the duct system, we recommend flexible connections from our accessory
range, see chapter Accessories.
♦ The safety of the fans has to be ensured by protective devices according to DIN EN 294 (DIN EN ISO 12100-1) and
DIN 24167–1, the explosion protection measures necessary according to standard DIN EN 13980.
Preconditions
♦ Ensure that the fan and all its components are
undamaged.
♦ Ensure that there is enough space to install the fan.
♦ Protect against dust and moisture when installing.
♦ Ensure that the information on the name plates (fan
and motor) matches up with the operating conditions.
♦ Fit the fans in such a way that there is sufficient
access for troubleshooting, maintenance and repair.
Danger
Risk of ignition of a potentially explosive atmosphere!
♦ Seal the system carefully.
♦ Install accessory parts correctly.
Aluminothermic Reaction
At high air speeds, in combination with aluminium, rust particles may lead to an aluminothermic reaction
which, in the worst case, can trigger the ignition of an explosive atmosphere. Upstream or downstream
components, or those which lie directly in the air flow, must not have any unprotected aluminium or steel
surfaces. To prevent an aluminothermic reaction, surface protection is required which at least fulfils the
cross-cut test classification 2 / DIN EN ISO 2409. Steel with an electro-galvanised or hot-dip galvanised
surface is not critical. However, care must be taken that appropriate protection is also applied to the cut
edges.
