Central ventilation unit – KWL 220/340 D
Installation and Operating Instructions

Different versions and unfavourable installation and operating conditions can lead to a reduction of output or increased
sound levels. The figures for the air-side sound are recognised as A-weighted sound power levels L
WA
(according to
DIN 45635, pt.1). The figures in A-weighted sound pressure L
PA
are influenced by room and installation-specific factors.
Accordingly, there are deviations in the figures.
In order to achieve the planned performance data (e.g. optimal volume flow, less noise and current consumption),
attention must be paid to the correctly planned and executed air distribution (intake air/supply air and extract air/
exhaust air). Furthermore, these must always be dimensioned accordingly.
2.6 Regulations and guidelines
If the ventilation unit is installed correctly and used to its intended purpose, it conforms to all applicable regulations and
CE guidelines at its date of manufacture.
2.7 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 the manufacturer.
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 product are not permitted and lead to a loss of conformity, and any warranty and
liability shall be excluded in this case.
