1 .3 Area of application
– Intended use:
The
KWL EC 45-160
unit with inner panel is a component of the EcoVent Verso ventilation unit. The unit is intended for
installation in a wall mounting sleeve in the external building wall and may only be installed as a complete unit. The air pas-
ses through via a closable inner panel on the internal side of the wall and via a facade panel on the external side of the wall.
The EcoVent Verso ventilation unit is designed for the supply and extract ventilation of living spaces and may only be
operated as a complete system. In order to ensure balanced ventilation, at least two ventilation units are required, which
operate in phases with regard to operating phase (supply air/extract air).
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.
Any use other than the intended use is prohibited!
– Reasonably foreseeable misuse:
The
KWL EC 45-160
unit with inner panel is 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.).
