NOTICE Unpleasant smells from the main
duct. Shut-off device does not close tightly in
cases of improper installation.
Before mounting, check the correct installation
position and check that the shut-off shutter func-
tions.
8.8.2 Safety instructions for the installation of
the plastic shutter
Preparing the shaft and suspended ceiling
1. Make an opening in the suspended ceiling.
2. Make an opening in the shaft for DN 75 or DN
80 connection duct.
3. Correctly attach main duct inside the shaft.
4. For fire protection systems, use ceiling com-
pound. To do this, encase the ceiling and pour
in the material from above.
5. Fit duct attachments to the ceiling ( Prepara-
tions for the ER-APB ceiling installation (with
fire protection) [
}
12] ). Only use permitted
mounting material.
DANGER Risk of incorrect installation if
non-permitted mounting material is used.
Only secure connection duct to ceiling with per-
mitted mounting material (duct clamp or clamping
band).
6. Connect permitted connection duct to main
duct and seal for ventilation, for example with
cold-shrink tape.
7. Apply wall/board compound. Seal gap
between brickwork and folded spiral-seams
duct. The gap remaining must be fully sealed
with non-flammable materials that are resist-
ant to deformation. For example, use concrete
or cement mortar or for wall boards, use fire
protection filler.
8. Fit suspended ceiling. Use ER GH housings to
ensure a suitable, flat surface so that the fan
insert can be safely inserted in the housing
later on.
9. Lay power cable: ER-AP: Preparations for wall,
shaft or ceiling installation without fire protec-
tion [

8.9 Preparing the shutter
NOTICE Odours may escape from the ventila-
tion channel.
If the installation position is wrong, the plastic
shutter will not close leak-tight.
Insert shutter at the top/to the right/to the left/to
rear in the exhaust socket of the housing to fit the
installation position. Ensure that the shutter
closes entirely leak-tight.
1. Before fitting housing, it is essential that the
position of the shutter is checked and its func-
tion ensured.

shutter [ } 16] and ER-APB: Safety instructions
for installation of the fire protection shut-off
device [

8.10 Attaching blind plug
1. Attach the supplied blind plug to the fan insert.
8.11 Conversion of air blow-out ad-
apter for using the AP housing
NOTICE In case of incorrect installation of the
air blow-out adapter, the function of the unit
is impaired.
Make sure that the adapter is tightly fitted to the
housing.
