CAUTION
Move impeller by hand to check unhindered running!
Before installation, check the minimum air gap between impeller tip and casing according to the following table:
If the observed values do not correspond to the specified
dimensions, the fan must not be installed or operated.
For questions, please contact Helios customer services “TGA”.
Own repair attempts are strictly prohibited!

3.6 Maximum permissible vibration limits according to ISO 14694 / ISO 10816-3
– Installation of a vibration monitor
The vibration monitor (on-site) must be installed on the casing of the fan and it must not lie in the turning range zone
of the impeller.
The air gap (see Fig.13) must not be affected by the installation of the vibration monitor!
– Selection of vibration dampers
In order to optimally dampen the vibrations created by the rotating components in the fan, the correct selection of
the vibration damper is crucial. The design is based on the determined total mass of the fan incl. mounting parts to
be dampened. In this respect, the individual net weights of the components must be added together.
Example:
AMD 900/4 30 kW as Z unit
