8. Environmental conditions and
operating limits
The permissible maximum temperature of the
air medium is + 40 °C.
The domestic air supply 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 has to be extracted
must be fitted with a non-closable, free supply
air cross section of at least 150 cm², e.g. with
Maico door ventilation grille MLK.
All ER-UP units have resistance to interfe-
rence in line with EN 55014-2 (depending on
pulse form and energy factor 1000 to 4000 V).
These values can be exceeded when
operating with fluorescent tubes. In this case,
additional interference suppression measures
(L, C components or RC module, protection
diodes, varistors) are required.
Take the risk of draughts into account when
planning by selecting a suitable installation
location.
8.1 Regulations for operation with
fireplaces
Sufficient supply air intake must be
ensured during operation with air-ventilated
fireplaces. The maximum permitted pressure
difference per living unit is 4 Pa.
The fan may only be installed in rooms with
air-ventilated fireplaces if:
●the evaluation criteria drawn up by the
responsible, regional master chimney
sweep are met,
●a parallel operation of air-ventilated
fireplaces for liquid or gaseous fuels and
the air-extracting equipment can be
prevented, or
●the extraction of exhaust gas from the air-
ventilated fireplaces is monitored by
special safety equipment. The ventilation
unit or the fireplaces must be switched off
if the equipment is triggered.
