1. Correctly attach main duct inside the shaft.
2. Apply ceiling compound. To do this, encase
the ceiling and pour in the material from
above.
Make a wall or shaft opening for the flexible
aluminium duct.
DANGER Danger to life due to fire trans-
mission in case of faulty ceiling compound.
It is essential that the remaining gap between the
main duct and the wall or ceiling is completely
sealed with non-flammable materials that are res-
istant to deformation. For example, use concrete
or cement mortar.
3. Connect the flexible aluminium duct to the
main duct and seal for ventilation.
4. Cut flexible aluminium duct to length, observe
a maximum duct length of 2 m.
Dimension the length of the flexible alu-
minium duct so that it protrudes from the
wall or shaft so that the ER connection
socket can be attached later. Also attach a
ventilation seal on the unit side.
5. Ensure a suitable, level substructure.
Compensate any unevenness in the wall or
ceiling so that the housing can be installed
without warping. Otherwise it may be that
the fan insert can no longer be inserted into
the housing or that the degree of protec-
tion indicated on the rating plate is no
longer guaranteed.
6. Attach spigot made from shaft material F90
around the shaft.
The spigot compensates for the length of
the shaft walls in the event of a fire.
7. Continue with the safety test of the APB shut-
off device: Electrically connecting the unit
