CHAPTER 2
GENERAL INSTRUC-
TIONS
Unit KWL EC 45
– Reasonably foreseeable misuse:
The KWL ventilation units EcoVent Verso 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 or solid matter content > 10µm in
air and liquid is not permitted. Transport media, which affect the materials of the fan, and abrasive media are not per-
mitted. Use in explosive atmospheres is not permitted!
1 .4

Personnel qualification

m DANGER!
The electrical connection and start-up must only be carried out by qualified electricians .
Installation, servicing and maintenance of the fan must only be carried out by qualified electricians .
EcoVent Verso individual room ventilation units can be used by children over the age of 8 as well as persons with physical,
sensory, or mental disabilities or lack of experience and knowledge, if they are supervised or instructed with regard to the safe
use of the unit and they understand the resulting risks. Children must not play with the unit. Cleaning or user maintenance
must not be carried out by unsupervised children.
2 .0 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.
2 .1

Certificates - guidelines

If the product is installed correctly and used to its intended purpose, it conforms to all applicable EU guidelines at its
date of manufacture.
2 .2

Shipping

The individual room fan unit 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.
2 .3

Receipt

The shipment (Set fan unit KWL EC 45, Ref.no. 3011) 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). 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
start-up according to chapter 7. In case of reshipment (above all, over longer distances; e.g. by sea), it must be che-
cked whether the packaging is suitable for the form and route of transport. Damages due to improper transportation,
storage or putting into operation are not liable for warranty.
2 .5

Mode of operation

The KWL EC 45 has an EC axial fan, which runs in a cyclical reversing mode. Thus, the supply air phases, whereby
the outside air flows into the building, continuously alternate with extract air phases, whereby the indoor air is extracted
from the building.
2 .6

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.
2 .7

Noise data

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 (e.g. wind load in wind-exposed locations).
