• 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.
8.2 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
conditions:
• the evaluation criteria drawn up by the respons-
ible, regional master chimney sweep are met;
• Parallel operation of air-ventilated fireplaces for
liquid or gaseous fuels and air-extracting equip-
ment can be prevented using safety devices or
• the extraction of exhaust gas from the air-ventil-
ated fireplaces is monitored by special safety
devices. The ventilation system or the fire-
places must be switched off if the equipment is
triggered.
