Warranty claims – exclusion of liability
All versions of this documentation must be observed, otherwise the warranty shall cease to apply. The same applies to
liability claims against Helios. The use of accessory parts, which are not recommended or offered by Helios, is not per-
mitted. Any possible damages are not covered by the warranty. Changes and modifications to the unit are not permitted
and lead to a loss of conformity, and any warranty and liability shall be excluded in this case.
1.4
Certificates - guidelines
If the product is installed correctly and used to its intended purpose, it conforms to all applicable European
Standards at its date of manufacture.
1.5
Shipping
The fan is packed ex works in such a way that it is protected against normal transport strain. Carry out the shipping
carefully. It is recommended to leave the fan in the original packaging. The fan must be kept in the housing or lugs
provided (if applicable) for transportation or installation. Only use appropriate lifting equipment and fastening devices,
which have a load capacity of at least the corresponding weight. Weight specifications according to the delivery note
or information on the unit.
Do not transport fan on the connection cables, terminal box or impeller!
Do not stand under suspended loads!
1.6
Receipt
The shipment must be checked for damage and correctness immediately upon delivery. If there is any damage,
promptly report the damage with the assistance of the transport company. If complaints are not made within the agreed
period, any claims could be lost.
1.7
Storage
When storing for a prolonged time, the following steps are to be taken to avoid damaging influences: Motor protection
by dry, airtight and dust-proof packaging (plastic bag with desiccant and humidity indicators). Vibration-free, water-tight
and constant-temperature storage at a temperature in the range -20 °C to +40 °C.
In case of a storage period of more than three months or motor standstill, maintenance must be carried out before
commissioning according to chapter 4. In case of reshipment (above all over longer distances; e.g. by sea), it must be
checked whether the packaging is suitable for the form and route of transport. Damages due to improper transporta-
tion, storage or putting into operation are not liable for warranty.

Application
– Normal use: The axial high-performance fans are suitable for conveying normal or slightly dusty (particle size < 10 µm),
less aggressive and humid air, in moderate climates and in the range of their performance curves, see Helios sales docu-
ments / internet. The permissible medium and ambient temperature is -30 °C to +40 °C. If applicable, deviating tempera-
tures can be found on the type plate. The axial high-performance fans are designed as components of a stationary venti-
lation unit for buildings. They can only be operated once they have been installed for their intended purpose and safety is
ensured by safety devices.
– Reasonably foreseeable misuse: The fans are not suitable for operation under difficult conditions, such as high levels of
humidity, aggressive media, long standstill periods, heavy contamination, excessive loads due to climatic, technical or
electronic influences. The same applies for the mobile use of fans (vehicles, aircraft, ships, etc.). Usage under these con-
ditions is only possible with release approval from Helios, as the standard version is not suitable in this case.
– Improper, prohibited use: Any use other than the intended use is not permitted! The conveying of solid matter or solid
matter content > 10 µm in air and liquid is not permitted. The fans must not be operated in contact with water and effective
weather protection must be ensured in case of outdoor installation. Transport media, which affect the materials of the fan,
and abrasive media are not permitted. The fan may only be operated in the specified performance curve range. Usage
outside of the performance curve range is not permitted and can lead to the excessive heating of the motor, and strong
vibrations and increased noise generation may also occur. Use in explosive atmospheres is not permitted!
1.10 Performance data
The unit type plate gives an indication of the mandatory electrical values; which must be coordinated with the local
supply network. The fan performances* were established on a test stand according to DIN EN ISO 5801; they apply to
the nominal speed and standard design using an inlet nozzle, without a protection guard and with unhindered inflow
and outflow. Different versions and unfavourable installation and operating conditions can lead to a reduction of out
put.
