Application
– Normal use:
The wall installation units KWL EC 45 are intended for external building wall installation. The air outlet is on the external
side of the wall via a stainless steel panel. A lockable plastic panel serves this purpose on the internal side of the wall
with an integrated non-woven air filter class G3 and sound insulation. In order to ensure balanced ventilation, at least
2 units, which operate in phases with regard to operating phase (supply air/extract air), are required for one residential
unit. Depending on the overall ventilation requirement of the residential unit, more than 2 units are normally installed and
the individual volume flows are automatically adjusted by means of the central control unit.
The standard equipment allows installation and use in frost-free rooms >+ 5 °C.
When operating under difficult conditions, such as high levels of humidity, long standstill periods, excessive loads and
climatic, technical or electronic influences, consultation and release approval is required, as the standard version is not
suitable for this.
Any use other than the intended use is prohibited!
– 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!
