• Cold smoke barrier as a standard feature.
• No additional telephony sound absorbers re-
quired.
• Control circuit board in spiral housing for
Centro-H-APB.
• Electrical plug connection for quick spiral hous-
ing installation in the lower part of the housing.
Spiral housing secured with snap-fit fasteners.
• Shaft level difference according to DIN 4109,
tested by IAB Oberursel (The Institute for
Acoustics and Building Physics in Germany).
• Upper part of housing with exhaust air filter.
Trouble-free filter change without tools.
6.5 Installation conditions
If installed in accordance with DIN 18017-3,
use is only permitted:
• in central ventilation systems with a common
main duct;
• with permitted connection ducts;
• with unit suitable for the system (Permitted ex-
haust air systems);
• with surface installation on the wall or ceiling;
• if correctly installed as per the instructions in
this manual and national technical approval;
• if unit is completely installed;
• with the correct air filters;
• with the outside air openings stated in the plan-
ning documents.

7.1 Environmental conditions and op-
erating limits
• Permissible maximum temperature of air me-
dium + 40 °C.
• 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
MLK door ventilation grille.
• Centro-E-APB and Centro-H-APB with resist-
ance to interference according to EN 55014-2 –
1000 to 4000 V depending on pulse type and
energy component. When operating with fluor-
escent tubes, these values can be exceeded. In
this case, additional interference suppression
measures (L or RC modules, protection diodes,
varistors) 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
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.
