– Isolate the device from the mains power supply and secure against
being switched on again!
– The rotating parts must first come to a standstill!
– Once the rotating parts come to a standstill, a waiting time of 3 min.
must be observed, as dangerous voltages may be present due to
internal capacitors even after disconnection from the mains!
• All plant-related safety regulations must be observed!
If applicable, further country-specific regulations must also be obser-

1.3

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 (supp-
ly 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.
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!
