MINIMUM DISTANCES AND PROJECTING
ENDS
The dimensions given must be considered an installation
recommendation for the ERK-MB and may differ, depending
on the local situation. The smoke extraction blade damper
must be installed in accordance with the technical documen-
tation, installation, mounting and operating instructions.
For functional test, service, retrofitting, etc., inspection ope-
nings must be provided on site in suspended ceilings, shaft
walls, connected ventilation ducts etc., if necessary. They
must be built in sufficient numbers and size and must not im-
pair the functioning of the smoke extraction blade dampers;
they may lead to increasing the distances.
1) The distance between smoke extraction blade damper and
adjacent component (wall/ceiling) must be determined ac-
cording to the particular installation situation or adjusted
to the dimensions of the projecting ends (e.g. actuator
housing) and is at least 75 mm.
2) The distance between two smoke extraction blade dam-
pers depends on the particular installation situation and is
described in the corresponding installation situations. (p. 8
and the following pages).
