• FWL-ABLV units have resistance to interfer-
ence in line with EN 55014-2 (depending on
pulse type and an energy component of 1000 to
4000 V). These values can be exceeded when
operating with fluorescent tubes. In this case,
additional interference suppression measures
(L, C or RC modules, protection diodes, varis-
tors) are required.
7.2 Regulations for operation with
fireplaces
Sufficient supply air intake must be ensured
during operation with air-ventilated fireplaces.
The maximum permitted pressure difference per
residential unit is 4 Pa.
The unit may only be installed in residential units
with air-ventilated fireplaces under the following
