1.3 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 per-
mitted and lead to a loss of conformity, and any warranty and liability shall be excluded in this case.
1.4 Regulations
If the product is installed correctly and used to its intended purpose, it conforms to all applicable regulations and CE
guidelines 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.
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: 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-tempe-
rature 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 8. 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.
1.8 Application
– Normal use:
The ELS-V.. fan units are suitable for conveying normal or slightly dusty, less aggressive and humid air, in moderate
climates and in the range of their performance curves (see Helios sales documents/internet). Operation is only admissi-
ble with fixed installation in a ELS flush-mounted or surface-mounted casing within buildings. The maximum admissible
media and ambient temperature is 40 °C. ELS-V.. complete units correspond to protection type IPX5, protection class
II and must be installed according to VDE 0100 part 701 in wet rooms in zone 1.
– 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 conditions 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 and liquid is not per-
mitted. Transport media, which affect the materials of the fan, and abrasive media are not permitted.
Use in explosive atmospheres is not permitted!
1.9 Performance data
The unit must be installed correctly with correctly designed extract air ducting and sufficient supply air flow to achieve
the optimum performance.
When using a vented fire place (chimney) in a ventilated room, there must be sufficient supply air for all operating con-
ditions (consult chimney sweep).
Different versions and unfavourable installation and operating conditions can lead to a reduction of output. In accor-
dance with DIN 18017, pt. 3, the flow rate for the simultaneous operation of multiple fan units in a line and caused by
external influences may be up to 15 % below the planned flow rate.
1.10 Noise data
The noise data is indicated as A-weighted sound power levels LWA (according to DIN 45 635 pt.1).
Noise data that refers to certain distances 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 and the room size among other factors.
