• The air supply to the home must be set up so

that virtually no air can flow into the living areas
from the kitchen, bathroom or WC.

• A room from which the air is to be extracted

must be fitted with a non-closable, free supply
air cross section of at least 150 cm², e.g. with
Maico MLK door ventilation grille.

• ER EC units have resistance to interference in

line with EN 55014-2 (depending on pulse type
and an energy factor of 1000 to 4000 V). These
values can be exceeded when operating with
fluorescent tubes. In this case, additional inter-
ference suppression measures (L, C or RC
modules, protection diodes, varistors) are re-
quired.
