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.
