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
permitted. 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.
2.1
Regulations - Guidelines
If the unit is installed correctly and used to its intended purpose, it conforms to all applicable regulations and EU gui-
delines at its date of manufacture.
2.2
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 casing or the
provided lifting lugs for transportation or installation – observe transportation diagram! In this respect, only use
appropriate lifting equipment and fastening devices. Weight information can be found in the table Chapter 5.0 on page
14 or the unit label.
m DANGER
Do not transport fan on the connection cables, terminal box or impeller!
Do not stand under suspended loads!
2.3
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.
2.4
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). The storage place must be
water proof, vibration-free and free of temperature variations. Storage temperature -20 °C to +60 °C, and these limits
must not be exceeded. The motor bearings must be turned at regular intervals (10 turns per month). In case of a sto-
rage period of more than three months or motor standstill, the bearings must be inspected before commissioning. In
this respect, the silent, free movement of the impeller must be checked. When transhipping (especially over longer
distances) check if the packing is adequate for method and manner of transportation. Damages due to improper
transportation, storage or commissioning are not liable for warranty.

Series version
These installation and operating instructions describe the Helios medium-pressure axial fans:
Series
Medium-pressure axial fans AMD..
Binding information on the individual fan types can be found on the type plate.
2.6
Performance data
The motor type plate gives an indication of the electrical values; which must be coordinated with the local supply net-
work. The fan performances* were established on a test stand according to DIN EN ISO 5801:2010-12; they apply to
the nominal speed and standard design using an inlet nozzle, without a protection grille with unhindered inflow and
outflow and a pressure-side pipe section with 2.5 x diameter length. In this respect, different versions and unfavourable
installation and operating conditions can lead to a reduction of output.
2.7
Noise data
The noise data* also refers to the aforementioned directive. Casing variations, unfavourable operating conditions and
many other things can lead to an increase in the specified catalogue values. Data that refers to certain distances (1
m, 2 m, 4 m) apply to free field conditions. With regard to installation, the sound pressure level can differ significantly
from the catalogue data, as it is highly dependent on the installation conditions, i.e. on the absorption capability of the
room, the room size among other factors.

Design
Series AMD 315-1120
The medium-pressure axial fan is a direct-driven fan where the motor is positioned in the airflow. The air
flow direction is blowing via the motor. The axial flow pattern allows a low-loss, linear airflow and ensures a high fan
efficiency. The cylindrical casing with flanges on both ends, integrated guide vane and motor support are made from
galvanised steel sheet.
The axial impeller with ten spatially curved blades consists of a cast aluminium alloy. Dynamic balancing according to
ISO 1940 T1, class 6,3.
