6 Mounting preparations

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).
4. Connect permitted connection duct to main
duct and seal for ventilation, for example with
cold-shrink tape.
5. 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.
6. 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.
7. Lay power cable: Electrically connecting the
unit [ } 23] .
6.4 Preparations for the electrical
connection
• Always note the relevant specifications for elec-
trical installations and when fitting equipment. In
Germany, observe DIN VDE 0100 and the cor-
responding parts in particular.
• Observe ambient conditions ( Environmental
conditions and operating limits [ } 10] ) and
technical data ( Technical data [ } 10] ).
• Observe permitted duct cross-section of max.
1.5 mm².
1. Lay power cable to the installation location.
2. Continue with the safety test of the release
device: Preparing the shutter [ } 16] .
6.5 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.
Before fitting housing, it is essential that
the position of the shutter is checked and its
function ensured.
For wall installation with air outlet direction
(exhaust socket) to the left or right , install the
shutter rotated by 90°, see following figures.
Prepare plastic shutter: Air outlet to top, left
or right
Wall installation
1. Upwards air outlet direction: Do not carry
out any modifications (factory setting).
2. Air outlet direction to the left or right: Pull
the shutter out of the exhaust socket, depend-
ing on the installation position, rotate and rein-
sert it. Make sure that the shutter is pushed up
to stop in the exhaust socket.
As a rule, use the standard installation position
with upwards air outlet direction
for ceiling in-
stallation (factory setting).
